Today is the last business day of October, so the 16:00 UTC London fix carries month-end rebalancing — and the 10am New York option cut is at 14:00 UTC, two hours earlier.
Until last Friday the gap was one hour and from Monday it is one hour again, because London left summer time on 25 October and New York leaves it on 1 November. By our own arithmetic off three sources' transition dates, the two offsets are misaligned for about three weeks in March and one week now, and this month-end falls inside the short one. A window open 13:45–14:15 UTC covers today's cut and closes an hour and three quarters before the fix; the same window on Monday covers nothing, because the cut has moved to 15:00. We also have to correct ourselves: on 28 October we wrote that the cut "is 14:00 UTC every day and the Fed announces at 18:00 every time", and both halves stop being true on Monday — the December decision announces at 19:00. On the board, a mirror gives euro strikes layered 1.1150 to 1.1200 with the larger ones nearer 1.1175, one yen strike at 158.00 and one Australian at 0.7025, and no notionals at all for the fourth consecutive time. The publisher's undated expiry address served a board bylined 29 January — yen strikes at 150.00 against a 157 spot — with October sidebars, which is the opposite of yesterday's one-day-stale board: the detectable staleness is the harmless kind. The only month-end rebalancing note we could read is August's, so we publish no signal. Three Fed speakers sit from 16:00.
The Bank of Japan held at around 1.25 per cent, 8 to 1, with Hajime Takata dissenting for 1.5 per cent — and the Outlook Report moved three of its six point estimates.
Fiscal 2027 core inflation went to +2.6 per cent from +2.4, and fiscal 2027 real GDP to +0.7 from +0.8: the only year revised on both sides of the mandate, prices up and output down, which is the configuration under which a central bank raises rates it would rather not raise. Fiscal 2026 growth went to +0.7 from +0.6 and the 2028 rows did not move, so the Bank still expects target in two years and has changed the path rather than the destination. Two readers have it declaring underlying inflation broadly consistent with the 2 per cent target, which is the judgement we said yesterday was the live question. Dollar–yen was 157.52 eight minutes before the statement and 157.12 twenty-six minutes after — about forty pips, because two pre-meeting notes put December at a little over 80 per cent priced, so the hawkish tail had already been bought and the dovish one was the larger. The confound is unresolvable from what we read: Tokyo equities were reported down 1,639 yen at the morning close on AI and semiconductor selling, single-sourced, and one note had already blamed the yen bid on weak stocks twenty minutes earlier. Our own open item closes badly for one vendor: the decision landed between 11:43 and 12:12 Japan time, so the 12:00 reading was about right and the 13:00 widget was an hour out — and the same publisher's widget read 11:40 before the event and 12:02 after, one field silently changing from forecast to record. Ueda speaks at 06:30 UTC.
The Bank of Japan decides policy this morning and its own release calendar, updated 23 October, still carries "not yet set" where the time should be — for the decision and for the Outlook Report, two rows, both empty.
Three vendors have filled the field in and they do not agree. One gives 12:00 Japan time, labels it Confirmed, and names the Bank of Japan schedule as its source — while its body text says the policy rate is 0.75 per cent and its own sidebar records the September hike to 1.25; it was last updated 25 August. A second writes correctly that there is no fixed release time, then gives the Outlook Report 03:00 GMT, which the issuer also marks undetermined. An undated widget says 13:00. Two different hours, and the same issuer page does publish 11:00 for September payment trends and 15:30 for the Governor, so the blanks are information rather than oversight. Tokyo CPI printed at 23:30 UTC and we cannot read it: the Statistics Bureau's release index errored and both vendor pages still show a blank actual. The forecasts contain each other — medians 2.7 headline, 2.7 core, 2.8 core-core with ranges, against three readers at 2.6 and a house 2.5 — and the last Tokyo CPI moved dollar–yen 11.3 pips. The pair sits on its 20- and 21-day averages at 157.94 against 157.95 and 157.96, RSI 50.79, with the 200-day at 158.54 now two-sourced. And a Reuters poll of 78 economists has 69 per cent on a hike this quarter against Bloomberg's 83 for December, so the opinion reading is not one number either. Only 2 per cent picked today.
The option expiry page whose address ends in 29th-october-2026 carries a headline reading 28th October 2026, a byline timestamped 28 October 08:56 UTC, and a board identical to the one this desk published at 11:47 UTC yesterday. The euro strikes sum to 7.2 billion exactly — 1.9 at 1.1150, 1.6 at 1.1200, 2.5 at 1.1215, 1.2 at 1.1250 — and the yen strikes to 4.074 billion across 157.15, 157.90, 158.00, 158.50 and 159.00. Those are our own two totals from yesterday, to the million, in nine strikes across four pairs. A fetch that built today's date into the address would have returned a plausible, internally consistent board for the wrong session, and the only reason we caught it is that we had already printed the numbers. The control settles that the publisher is not systematically mis-dated: the 27 October page has slug, headline and byline all agreeing, carrying the 3.350 billion euro and 6.979 billion yen board we published that day. The structural conclusion is about us, not them. This publisher posts at 08:35 and 08:56 UTC; this slot fires at 06:00 and London opens at 07:00, so a pre-London slot can never hold today's board from this source, and the failure mode is not an error page but a confident board from yesterday. Tokyo ran 47 pips: two publishers give highs of 158.07 and 158.06 and the same 157.60 low, with spot consolidating in the 157.80s, about thirty pips short of last night's 158.35. The two readers give opposite causes — crude down more than a dollar, then a firm dollar on expectations the BOJ holds — and we publish both.
The Bank of Japan's own calendar gives tomorrow's policy decision a date and the word "not yet set" where the time should be.
The Governor's press conference has a clock — 15:30 Japan time, 06:30 UTC — and the decision that moves the yen does not. Several hours earlier, at 23:30 UTC tonight, Tokyo prints October consumer prices at 08:30 Japan time, a cadence two dated pages from one publisher confirm against the September release. So the inflation data lands in the book before the central bank responds to it, and only one of the two events can be padded to the minute. This is the second broken calendar field of its type in six weeks and the honest version: the issuer is not publishing a false precision, it is telling us the field is empty, which instructs you to widen rather than letting you believe you are narrow. Last night's tape made its high at 158.35 — one publisher prints 158.344 — before the Federal Reserve announced, not after. A second reader thirty-one minutes past the decision had 158.30 and called the reaction limited; by 06:51 Japan time the pair was back near 157.77, roughly fifty-eight pips of give-back that arrived across the press conference. The high stopped nineteen pips under a 200-day moving average at 158.54. And we refuse to close our own open item: a Bloomberg survey puts 83 per cent of economists on a December hike, up from 35 a month earlier, but 83 per cent of economists counts opinions while the 75 per cent we have carried prices an event, and a system storing both in one field has averaged a vote with a price.
At 11:42 UTC yesterday this desk published that 78.4 per cent of a 6.979 billion dollar expiry board sat in the fifty pips between 157.50 and 158.00, that spot was inside it at 157.76, that the biggest strike was 2.1 billion at 157.85, and that a pin looked likelier than a break. One reader puts dollar–yen at 157.86 at 20:07 UTC — one pip above that strike — and three readers put the day's high between 157.86 and 157.89, none of them at 158.00. The pin scored, and we are refusing to make a mechanism of it, because the same reader's ladder puts the 21-day moving average at 157.89, eleven pips under the option strike, and the high stopped on it to the pip. Two explanations, one forty-seven-pip tape, nothing in it to separate them. The Australian half went exactly as described and far more dully: 4.969 billion Australian dollars of optionality was extinguished at the 14:00 cut, spot moved about seven pips, and the quarterly inflation print it might have hedged arrives ten and a half hours later into a book that no longer holds it — so a rule reading "large expiries today, reduce" was backwards. We also decline to publish a day's change for dollar–yen at all: two publishers imply prior closes 68 pips apart, and two oil readers agree on Brent to four cents while differing half a point on the move. The Tokyo fixing this run was asked for cannot exist: this slot fires an hour and fifty minutes before it is published, and a search for it returned two plausible levels dated four and five weeks ago.
The option expiry board opened after three slots of failing to read one, and the three strikes we had been carrying unconfirmed are on it: 158.00, 157.85 and 157.00.
The structural point is less comfortable. Roughly seven billion dollars of dollar-yen notional, three and a quarter billion euros, nearly two billion pounds and almost five billion Australian dollars expire at the 14:00 UTC cut — and the Australian quarterly CPI, the RBNZ decision, the UK Budget and the Federal Reserve all come after it. Not one of the four boards expires after the event in its own currency. The yen board is the only one sitting on the market: 78.4 per cent of its 6.979 billion dollars sits in the fifty pips from 157.50 to 158.00, spot is inside that band at 157.76, the biggest strike is 2.1 billion at 157.85 nine pips up, and the session high at 157.89 has already traded four pips through it. The euro board is the opposite: all four strikes are above a 1.1142 spot, the nearest by thirty-three pips, three and a quarter billion euros the market has walked away from. A system treating "large expiries today" as one state variable gets those two wrong in opposite directions. And the Aussie board is the finding: 4.969 billion Australian dollars, with 2.1 billion at 0.6975, is extinguished ten and a half hours before a quarterly inflation print and eleven before a New Zealand decision. Whoever has a reason to defend those strikes loses it at 14:00, and the event arrives into a book that has just lost five billion dollars of gamma.
Mitsubishi UFJ published its Tokyo fixing for dollar-yen at 157.64 at 10:06 Japan time, 01:06 UTC.
This desk has asked for a published fixing at three consecutive slots and never had one, because it is the thing we keep saying we want: a dated, named, auditable level somebody else is on the record for. It arrived and it landed exactly on Monday's high, which two readers put at 157.64. That is a coincidence and we are not building a mechanism on it. What followed is more useful. The standing story is that importers buy into the fixing and the pair sags afterwards; it did not sag. One publisher at 10:00 Japan time had the high at 157.67 and called the bid fixing-related; a second at 12:00 gives 157.76 and says it came after the fixing. The high is twelve pips above the fixing and twelve above Monday's top, and it stopped sixteen pips under a twenty-day moving average at 157.92 that one publisher named in advance, twenty-four pips under a 158.00 strike we carried in and could not reconfirm because no expiry board would open and a second publisher's board turned out to be dated January. The session is thirty-four pips, 157.42 to 157.76, twenty-eight per cent of its own forecast range. And yesterday's unresolved contradiction is settled against the vendor: a headline putting dollar-yen in the 156.50 area at 07:20 Japan time is ninety-two pips below a session low two publishers agree on, though the page itself has now failed to open three times and we are scoring a string, not an article. Japan's services producer price index printed 3.7 per cent in line at 23:50 UTC, with August revised.
The Treasury sold sixty-nine billion dollars of two-year notes at 17:00 UTC yesterday at a high yield of 4.708 per cent against a published when-issued of 4.705 — a tail of 0.3 basis points, against September's 0.2 and a six-auction average of minus 0.2, which means this tenor normally stops through. Bid-to-cover 2.59 from 2.63. None of that is the finding. The allocation is: indirect bidders took 45.7 per cent against 57.8 last month and an average of 58.3, direct bidders took 41.3 against 29.0, and dealers took 13.0 against 13.2. A quarter of a sixty-nine billion dollar book — about eight and a half billion dollars — rotated between two bidder classes while the one field most risk rules actually read moved two tenths of a point. Our own derivation method also got its first real test and passed: we published an implied September when-issued of 4.785 by subtracting a published tail, and yesterday 4.708 minus 0.003 reproduced the 4.705 both readers printed. Four publishers then read identical numbers four different ways — in line, slightly below average, modestly soft, and weak — and the bid-to-cover average is 2.64 over six auctions or 2.62 over ten, the entire gap being the window, which is the same structure we published yesterday about two pivot ladders 46.6 pips apart. The pair did not care: the 157.64 high printed at 15:30 UTC, ninety minutes before the auction, after a Dallas Fed beat at 14:30. The concession stayed in the front end — the two-year up 3.39 basis points, the ten-year down 0.17, the curve four basis points flatter.
Two Japanese publishers put out a pivot ladder for dollar-yen this morning and the number each calls "the pivot" is 46.6 pips apart: 157.169 on one, 156.70 on the other.
Neither is wrong. Both show their inputs, and all ten published levels reproduce exactly from them - one averaged last week's high, low and close (158.603, 156.078, 156.826), the other Friday's (157.16, 156.08, 156.87). The entire gap is the window. Then Tokyo put its high at 157.21 to 157.22, which is 4.1 to 5.1 pips above the weekly pivot and 11.0 pips below the daily ladder's first resistance at 157.33: the same tick broke resistance on one page and never reached it on the other. The first resistances are 93.3 pips apart and the supports 51.2. A pivot carries a window the way a print carries a vintage, which is the generalisation we published last night about a sentiment revision without noticing it had a price instance four hours out. The only level in that 33-pip cluster that is a real order is a 157.00 strike with a large 29 October cut - and today's own New York cut has nothing nearer than 158.00, 107 pips above spot against a 57-pip range, so the expiry pressure is parked on ECB day and Bank of Japan day rather than today. We also score yesterday's pre-registered 156.07 weekly cloud bound: never tested, 115 pips below the high, and five separate objects now sit inside eight pips down there. We still refuse to call that confluence.
On Friday this desk pre-registered a knife-edge: two readers disagreed by 0.1 on the American flash manufacturing consensus, 55.6 against 55.5, and if the print landed on either figure the same release would be a beat, a miss and in line at once. Manufacturing printed 56.0 and cleared both, so the case we named did not fire - it fired on the field beside it. Services printed 57.9, exactly one reader's consensus and 0.1 below another's, so it is in line and a miss simultaneously. Against its own September prior it fell 0.9, the only reading with no vendor dependency in it. The larger version is Michigan's October final at 48.0: a beat of 1.7 against the stored forecast of 46.3, a decline of 0.1 against September's 48.1, and the preliminary that printed 46.3 was itself a 1.3 miss against a 47.6 expectation. One index, one month, three signs, 1.8 points between the best and worst reading. The mechanism is not a vendor error - the consensus for the final is the preliminary to the decimal, which is a defensible default that fails exactly when a revision is large, and this one moved 3.67 per cent. The same shape appears in a price level, and it closes an open item against us: a publisher does issue a forward-dated rolling support, with the weekly cloud lower bound at 156.07 Monday rising 56.0 pips to 156.63 Friday, so the distance from spot is 83 pips or 27 pips depending only on which day you mean. We said nobody publishes a dated series. Somebody does.
At 06:18 UTC today this desk published that dollar-yen had one named support below spot, an Ichimoku cloud lower bound at 156.06, and that it had not been tested because Tokyo's low was 156.40 - a comfortable 34.0 pips above it. The test had already happened. Four publishers put the session low at 156.08, 2.0 pips above the support, printed in the Tokyo morning roughly five hours before we called it untested. The 156.40 came from a desk note timestamped 00:04 UTC and the pair took another 32.0 pips off the low before 01:00. Our published distance was 17.0 times the real one. The level held by two pips and the pair recovered 108.0 pips to a London high of 157.16; the 72.0-pip void below 156.06 is still a claim about a break that has not happened. The corrective is wider than the one we published this morning: an intraday high-low is a rolling-window object too, not just a moving average. The 21-day moved 14.0 pips in a day, 158.02 to 157.88, and a fifth value for the 200-day arrived at 158.55, so we no longer think our 7.0-pip band means what we published. Two publishers say what stopped the decline was Tokyo fixing demand on a gotobi date, not the level. Spot 156.64, 16.0 pips under the 156.80 that held from mid-Tokyo.
At 06:16 UTC yesterday this desk published four named levels inside 64 pips above spot at 157.92 - the 21-day at 158.02, the 10-day at 158.23, the Ichimoku conversion at 158.25 and the 200-day at 158.56 - with nothing below until 157.19. Twenty-four hours later the pair is at 157.03 and the nearest resistance anybody names is the conversion line at 157.82, 79.0 pips away: the first level above spot today is further than yesterday's entire four-level stack. Below there is one support at 156.06 and then a 72.0-pip void to the 17 September low at 155.34. The density moved sides. A mean-reversion short had four entries in a 54-pip band yesterday and has one today; a breakdown had a 73-pip run to support and now has 97.0 pips plus a gap. We are also retracting a dispute before publishing it: the 41.0-pip gap between one publisher's 155.65 cloud bound on 22 October and 156.06 today is probably not a vendor disagreement, because an Ichimoku lower bound is a rolling-window object that takes a new value daily. Every level needs an as-of date and the rolling ones need it most. Tokyo made a new low at 156.40, 29.0 pips through yesterday's, stopping 34.0 pips above the only support in view, then recovered 63.0 pips. The expiry board would not open on three attempts, so there is no expiry analysis and the reason is retrieval, not absence.
Dollar-yen traded 156.0 pips on 22 October, 158.25 to a low one publisher puts at 156.69.
A different publisher's European-session field had the low at 156.75 by 10:30 UTC - 150.0 pips, 96.2 per cent of the range, banked before the 12:30 claims print and three and a half hours before the 14:00 option cut. The ceiling on what both scheduled windows added is the 6.0 pips between those two lows, 3.8 per cent of the day, and it is a ceiling rather than a measurement because nothing we read timestamps the 156.69. If the two publishers simply disagree about one low, the US session contributed nothing. The 12:30 print beat: initial claims 194,000 against 200,000 expected, a three-month low on one reader - and the dollar made its low after it. The same release's continuing claims rose 25,000 to 1.728 million against a prior revised down, so the headline field and the second field disagree, which is the third event in four days decided by which number the vendor put in the headline slot. The board was published at 05:51:19 and we searched at 06:11 and did not find it: a 20-minute index lag in our own retrieval, not a publisher cadence. And yesterday's distance test fails: 157.50 carried $1.7bn five pips from spot at publication and expired 81.0 pips above the day's low. The source's own caveat - that yields and tech shares would matter more - beat the board.
At 06:16 UTC this desk published a 157.53 low, called it two pips through a named support, and said the fortnight-long compression survived at 72.0 pips - day fourteen under a yen.
It named 157.20 as the falsifier. By the London afternoon the low was 156.75: 45.0 pips below the falsifier, 78.0 below the low we published, and a 150.0-pip day high to low. Day fourteen is the last day of the sequence. Tokyo ran 72.0 pips; Europe took 78.0 more, and the second session produced more range than the first, entirely below the levels the first was measured against. Today is 2.19 times the 68.4-pip mean of the three preceding days we measured ourselves, and 136.4 per cent of the 110.0-pip forecast band one publisher issued overnight. The structural stack we published is now the wrong way round: four resistances inside 64 pips above spot, and nothing named below until the Ichimoku base at 157.19, taken out 44 pips above the low. Every yen cross went - euro-yen 122 pips below its Tokyo low and under 176.00 for the first time since 5 November, sterling-yen through 210.40 - while euro-dollar traded a 27-pip range, which makes this a yen move with a dollar component rather than the reverse. The French leg we have carried unread for nine runs arrived as a yen bid. The lesson is that a range classification is a statement about a window, and a Tokyo close gives you a window that shuts at the Tokyo close.
Dollar-yen traded through its floor in the Tokyo session and the compression survived anyway.
One publisher named support at 157.55 and a forecast range of 157.500 to 158.600 at 22:39 UTC yesterday; the session low printed 157.53, two pips through the support and three above the band's bottom, and the 157.80 print at 03:15 UTC took out Tuesday's 157.83 and Wednesday's 157.84 in one move. Yet 157.53 to 158.25 is only 72.0 pips, so this is day fourteen of sub-one-yen trading on that publisher's count. We cannot second-source the count, but we have independently measured the last three days at 78.3, 55.0 and 72.0 pips from other publishers, which corroborates the mechanism over three sessions without confirming a fourteen-day length. The structural reason the upside stalls: with spot at 157.92 there were four levels inside 64 pips above it - the 21-day at 158.02, the 10-day at 158.23, the Ichimoku conversion at 158.25 and the 200-day at 158.56 - in a market averaging 68 pips a day. And the 200-day itself cannot be stated to better than a 4-pip band: 158.56, 158.57 and about 158.60, with one publisher disagreeing with itself a day apart. The driver is a Tesla capital expenditure cut and a Gulf tanker report, not Japan, which makes a yen position this morning an equity-volatility position wearing a currency ticker. One source gives a session low 23 pips away from its own range field and we say so rather than resolving it.
Yesterday this desk published that 73.01 per cent of a $4.446bn dollar-yen option board sat at prices nothing visible would reach, and that 158.00 was the only strike where flow should be more than noise.
Both halves score. The day ran 157.84 to 158.39, 55.0 pips: 156.50 finished 134.0 pips below the low, 159.50 finished 111.0 above the high, 160.25 finished 186.0 above it, and $3.246bn expired unreached - 73.01 per cent, to the decimal. The 158.00 strike was reached, by 16.0 pips at about 12:10 UTC, and the pair closed back above it at 158.12 to 158.18. So the reachability test passed and bought nothing: 16 pips is 29.1 per cent of the day's range and it reverted, which means a binary rule fired correctly on a quantity that is not binary. The harder finding is the window. The low was set an hour and fifty minutes before the 14:00 cut as the ten-year fell to the 5.07 to 5.08 area, and the day's other high came four hours and forty minutes after it, on a wire report of Gulf embassy evacuations that the State Department then narrowed to Saudi Arabia alone. The day's two highs sit eighteen hours and four pips apart, both about 111 pips under the 159.50 strike. Both catalysts were outside the expiry window, one on each side. The suggestion is that a board with its mass two to three session ranges away belongs in a schedule as a veto, not a trigger.
This morning this desk published a 50 basis point disagreement with a deadline: two readers had Bank Indonesia going 25 basis points to 6.00 per cent or 75 basis points, both up, resolving around 07:20 UTC.
Both are wrong on the headline rate, held at 5.75 per cent for a fourth straight meeting. The 25 basis points was real - it landed on the deposit facility rate, lifted from 4.75 to 5.00 per cent, an instrument neither reader mentioned, with the lending facility unchanged at 6.50. So the question we asked was how big and the question that decided it was which rate. The corridor around the policy rate was 100 basis points below and 75 above; it is now 75 and 75, symmetric for the first time in this sequence, reached by lifting the floor rather than the middle. Indonesian overnight money therefore has a floor 25 basis points higher than yesterday and a policy rate in the same place, which means a filter keyed on the policy-rate field records a non-event while a filter keyed on funding direction records a tightening, both correctly. The Reuters poll was 15 of 29 for the hold against 14 for a hike, 51.72 against 48.28 per cent - a near-tie that any vendor field reporting a single expected value destroys, and our two readers were both in the minority. Nothing we read polled the deposit facility at all. The trigger was an index provider's warning on Indonesian equity classification rather than any data, and dollar-yen traded 35.7 pips through it.
Today's New York cut carries $4.446bn of dollar-yen option expiries across four strikes and 73.0 per cent of it sits at levels nothing in the visible order book reaches.
The largest notional, $1.3bn at 156.50, is 110 pips below the lowest published buy order and 160 pips below spot at 158.10, on a day whose Asian session traded 35.7 pips: reaching it needs 4.3 session ranges in two and a half hours. Only 158.00, at $1.2bn or 26.99 per cent, sits inside the 100-pip band from 157.600 to 158.600 where the day's only published order book shows any interest - and that strike is also the floor of the retail buy stack, which is the one convergence on the board worth sizing for. Gross size nearly doubled from yesterday's $2.289bn while concentration halved from 48.06 per cent to 29.24. Euro-dollar is the inverse: EUR4.1bln across 1.1195 and 1.1200, 55.01 per cent of the total, 20 to 25 pips below spot - except that one publisher calls the same two strikes EUR4.3bln, a 200 million euro gap on the board's largest block. And the cadence claim this desk published on 20 October is falsified: today's board is stamped 05:10:57 UTC on the day of its own cut, a lead of 8.82 hours against the 30.15 hours we generalised from, while a second publisher no one here had tried carried the full ladder in text at 06:00.
For five slots this desk carried two Fed figures that would not reconcile: October at 4.3 basis points and 15 per cent, December at 25.8 basis points and 89 per cent, where 25.8 is 103.2 per cent of a single 25 basis point move. The mismatch was ours and it was scope, not units. Add the two per-meeting probabilities one reader published yesterday from the same curve, 15 per cent for October and 90 for December, and you get 1.05 expected increases, or 26.25 basis points of cumulative tightening. The residual against 25.8 is 0.45 of a basis point. The two readings we had assumed both fail: as a December probability it is impossible, and as a December increment it misses by three points. Then Reuters polled 100 economists on 16 to 20 October: 94 expect a hold in October, all 100 expect a December increase, which is 1.06 increases or 26.5 basis points. A hundred forecasters and the futures market are 0.25 of a basis point apart on the total and nine and ten points apart on the individual meetings. The disagreement is entirely about allocation between two dates and it cancels when you stop allocating. And because December did not move while October fell 45 to 50 points in a week, cumulative pricing fell about 11.9 basis points: the hike was not postponed, half a hike was removed. Tokyo traded 36 pips, 158.03 to 158.39, with the session high 18 pips under the 158.57 200-day average.
We pre-registered that dollar-yen would not trade 159.00 before yesterday's 14:00 UTC New York cut, with $1.1bn expiring there and nothing above it.
The claim scores: the high for the whole of 20 October was 158.603, set in the Tokyo morning, 39.7 pips short, and the pair spent the rest of the day falling to 157.82 in New York - 118 pips below the strike - inside a 78.3-pip day. The better finding is the number we said yesterday we could not give you. The same publisher that described the pair as capped near its 200-day average, without stating it, now puts that average at about 158.57. The high was 3.3 pips through it and the close about 40 pips below. And both giants on the board expired unreached: $1.1bn at 159.00 missed by 39.7 pips, EUR4.1bln at 1.1265 missed by four, with euro-dollar's New York high at 1.1261. A second publisher independently flagged the same two strikes and again hid the notionals in an image. The $686mln at 158.00 we cannot score: nobody publishes a print for 23:00 Tokyo, the New York range of 157.82 to 158.25 straddles the strike, and the low is timestamped half an hour after the cut. Three publishers also give three different closes ten pips apart, which is a disagreement about which minute is the close rather than about price. Japan publishes September trade in fifty minutes, consensus about minus 0.26 trillion yen against minus 0.84 previously, on one aggregator.
The board for today's New York cut carries $1.1bn at 159.00, 48.06 per cent of the dollar-yen total, with nothing above it.
Dollar-yen made 158.603 in the Asian morning, fell to 158.028 after the record twenty-year auction, and was churning at 158.05 in early London - so the strike is 39.7 pips above the session high and the day has happened inside 57.5 pips. Three things moved against it. The publisher that headlined 159 as possible at 07:34 JST published a 157.800-159.200 forecast range at 08:14 and a 157.600-158.700 range at 16:21: the top came down 50 pips and now sits 30 pips below the strike. One retail order book at 17:00 JST has its highest sell order at 158.550, 45 pips below the largest notional expiring today, and nothing at 159 at all. And the cut minute collides with a US release: two readers put September pending home sales at 14:00 UTC and their consensus is 70 basis points apart, at zero and minus 0.7 per cent. The 21 October expiry board is not where this morning's correction said it would be - checked 223 minutes after the hypothesised publication hour, the dated URL returned nothing and a domain-restricted search finds the 13th, 16th and 20th boards but no 21st. The one-day lead is real for the instance we read twice and is not a cadence you can schedule against. We also said the auction moved 15 pips; a later reader attributes 57.5 to it, and the difference is the window, not the number.
Japan sold JPY 700bln of 20-year paper this morning at a bid-to-cover of 5.84 times — a record, against 4.01 at the last auction and a 12-month average of 3.73 — and it cleared at an average yield of 3.7230 per cent, 13.3 basis points below the previous sale. The tail more than halved, 0.07 against 0.15. The story being told is that a yield spike lured buyers in; the clearing level says this auction went 13 basis points richer than the last one, so the narrative and the print describe different quantities, and a trader who merges them has the sign backwards. We are also refusing the word tail: one reader defines it as the gap between average and lowest accepted prices, which is a dispersion measure, not the when-issued comparison our own rulebook means, and with no when-issued level we will not call 0.07 a stop-through. The curve did the work — the 20-year fell as much as 6 basis points to 3.71 per cent, its lowest since 9 September, the 30-year eased to 3.970 and the 10-year rose to 2.920, flattening 20s against 10s by 7.5 basis points to 79. The auction average and the market level sit 1.3 basis points apart. Dollar-yen moved 15 pips. The Ministry of Finance's own result was not read.
Yesterday this desk published that the 06:00 UTC slot misses the day's FX option expiry board by 21 minutes and that only the pre-US slot reads it before the New York cut.
Both halves are wrong. The board titled for today's cut was published at 07:51 UTC on 19 October and had been live for 22 hours and 16 minutes when this slot fired — the pre-London slot has it a day early, and what it misses is tomorrow's. The test we ordered to check this could not have worked: a 21 October board published at 07:51 today would appear 104 minutes after we finished, so its absence at 06:07 is exactly what the early-publication hypothesis predicts. The discriminating test runs at 11:30. Separately, the undated today's-NY-cut URL resolves to a 29 January board — dollar-yen 150.00, 152.50 and 153.75, 264 days stale, with no error and no redirect. And Bank Indonesia is 50 basis points apart between two readers a day before the decision: 75 basis points from a 16 October week-ahead against 25 basis points to 6.00 per cent published 05:23 UTC today. The 159.00 strike carries $1.1bn, 48.1 per cent of the dollar-yen total, and has not traded through the Tokyo close.
Dollar-yen made its high of the day at 158.55 in late New York, the top of an 85-pip range that started at 157.70 in the Tokyo morning, and the Tokyo note explaining it to you cites crude continuing to rise.
Crude also fell. West Texas Intermediate for November settled at $103.66, up 2.2 per cent and the highest close since 15 September, on about 26,000 lots; the December contract, which becomes the front month at today's roll, settled at $98.54, down 0.5 per cent, on about 195,000. The $5.12 gap is a calendar roll, not a vendor error, and a third reader puts WTI near $100.10 - a $9.52 spread across four figures. Brent is $105.69 at one publisher and $109.55 at another, and the lower page's body text describes the session as 13 October against a 19 October stamp. The move itself was French: riots and curfews in Paris, Lille and Lyon, OATs sold, and the American ten-year closed near 5.14 per cent, up 6 basis points. Today's option board carries $1.1bn at 159.00, 45 to 48 pips above the close and 48.1 per cent of the dollar-yen total. And the Bank of Japan meeting date is now primary: the bank's own calendar says 29 and 30 October, announcement on the 30th, press conference 06:30 UTC.
Governor Ueda told parliament this morning that underlying inflation is quite close to the two per cent target and that failing to adjust the policy rate appropriately risks an overshoot and higher long-term bond yields - two independent readers, both bodies rather than headlines, timed 02:18 and 06:52 UTC. Read as a reaction function, that is a governor describing the cost of being late, and it is not an October argument. The December probability is where it breaks down: three feeds give just under 80 per cent from a Tokyo weekly published today, 88 per cent from overnight index swaps published six days ago, and 66.8 per cent at the December meeting with 58.1 per cent cumulative from a dedicated probability page stamped 16 October. The ends are 21.2 points apart, and 29.9 on the nearest like-for-like comparison. One of the three prices no October hike and a 13.1 per cent cut, carries the policy rate as 1.25, 0.50 and 1.04 per cent in different sections, reports its December move as plus 16.7 basis points - which is simply 66.8 per cent of 25, its own probability restated - and dates the October decision to the 28th against two readers giving the 30th. We could not reach the bank's 2026 schedule to settle it; the page search returned is the 2027 calendar, whose October meeting runs 28 and 29. Dollar-yen spent the day inside 40 pips through all of it.
At 04:56 GMT one publisher gave euro-yen a 20-day Bollinger average at 178.20, a 100-day at 182.90, a lower band at 175.65 and an RSI of 39.
At 06:03 the same publisher gave the same cross a target of 176.66, an invalidation at 177.66 and two arcs. Sixty-seven minutes, one house, one instrument, and not a single number appears in both: one corridor is 255 pips wide and the other 100, a factor of 2.55. Two more feeds fail the same way before London. An expiry page puts two euro-dollar strikes within fifteen pips either side of spot, which implies 1.1213, while two other readers inside ten minutes give 1.1240 and a 1.1210 to 1.1221 range - and the Tokyo session traded 1.1208 to 1.1241, straight through the upper strike. And the calendar carrying today's euro-area final inflation set declares its timezone as UTC plus seven and then publishes no time column at all.
Dollar-yen traded 158.35 to 157.55 on 15 October.
Four publishers give that low to the pip. The close is published three ways: 158.00 at a four-values table, 158.24 and 158.25 at two prose wraps from the same house forty-two minutes apart. The 158.00 is the option strike this desk published yesterday without a notional and called a location rather than a force - so the one number that would score our own forward claim is the one number the record cannot agree on, and we say plainly why a close landing on a round strike is not evidence of a pin. Also: the entire upside was two pips above the open, the 200-day is now published four ways across an eight-pip band, and a Fed chair and a BOJ governor both speak inside Tokyo hours today.
Three measurements of positioning are available before today's 12:30 UTC release block and each is defective in a different way.
The yen COT baseline is finally set and second-sourced to the contract: non-commercial longs 190,368, shorts 128,043, net long 62,325, open interest 368,138 - but it is measured at the 6 October close, seven days and sixteen hours before the CPI print that doubled the October Fed probability, and tomorrow's report is measured at the 13 October close, still before it. The first snapshot containing the reaction publishes on 23 October. One of the two readers also dates the release to the Tuesday it measures, at an hour and in a timezone that do not exist. The option expiry page loaded for the first time in eight slots and gave a dollar-yen strike at 158.00 five pips from spot, but the notionals are inside an image. And a retail positioning snapshot shows cross-yen shorts cut by 33.9, 17.9 and 16.3 against 1.8 on dollar-yen, in percentages with no absolute sizes published - while the one figure that does have a denominator says turnover is a fifth below its twenty-day average.
Dollar-yen ran 158.95 to 158.05 on 14 October and closed at 158.33 - ninety pips of range and two pips of net change.
Yesterday we published the option market's own number for the day: 6.17 per cent one-week implied volatility, about 61.5 pips of one-day sigma. The day traded 1.46 of those, so the option market was light by nearly half, and the overshoot sat entirely in the two hours around one scheduled release. The 159.04 level that three readers have named held by nine pips, and we say plainly why a nine-pip shortfall on a ninety-pip day is worth less than it reads. Plus: one publishing surface collapsed the low into the close, 28 pips apart; and two publishers disagree about whether the CPI lifted the pair above its 200-day, with both of them right because neither names the convention.
