Four feeds put an October Fed increase at 16, 19, 19.4 and 20 per cent before yesterday's CPI.
Four hours after it, one reading of the futures market had 43.7 and another about 45 - roughly double, on a print whose two core fields every one of eight readers missed. But the October number is not the finding. The same feed's cumulative December buckets sum to exactly 100.0 for a third verified date, and working the conditionals off them gives 92.45 per cent for a December increase following an October one and 92.36 per cent following an October hold. The two differ by 0.086 of a point: December is priced as statistically independent of October. Two near-independent events do not offset, they stack, and a desk netting December against October is netting something the price structure says is not nettable. Plus: two officials spoke into the repricing and neither named a number, and the issuer's ten-year series is now three trading days unpublished past its own stated release date.
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.
US September CPI printed at 12:30 UTC: headline 0.6 per cent on the month and 3.7 on the year, core 0.3 and 2.6.
We spent five slots assembling eight readers across four fields. The one field they all agreed on - core monthly at 0.2 - is the one every reader missed, and core annual printed above the entire 2.39 to 2.5 range. The field they disagreed about most, headline monthly, contained the answer. And the dispute itself was malformed: the 0.53 and the 2.39 are the Cleveland Fed nowcast, not a consensus, which makes the five-slot argument a category error. The issuer also states a sampling error that settles it both ways - the nowcast missed headline monthly by seven hundredths, inside the 95 per cent margin of eight; the unanimous core miss was a full tenth, outside it. Unanimity is not precision. Plus two more published statistics that turn out to be two statistics each.
One vendor put one-week dollar-yen implied volatility at 6.17 per cent this morning.
On our conventions that is about 61 pips of one-day standard deviation and 135 over the week - and the entire Tokyo session traded 40 pips, two-thirds of one sigma. The dollar index ran 102.20 to 102.075 and back to 102.238, finishing just above a ten-day line the publisher gives as 102.161 and does not label. 159.04 now has a third reader naming it, 69 pips away, 1.12 sigma. Fifth straight slot with no expiry ladder for the 14:00 cut, and two searches returned nineteen results with not one from 2026. Plus a correction: the issuer has published 9 October at 5.24 per cent, so Monday night was not a phantom close, and our 0.32-basis-point figure should have been 2.32.
Dollar-yen ran 158.65 to 157.83 on 13 October, eighty-two pips with a fifty-four-pip reversal on a Bank of Japan wire report, and closed at 158.33 - fifty pips above its own low and twenty-eight below Monday.
Tokyo has opened in a seven-pip box, 158.32 to 158.39, eleven and a half times quieter than the day it is reacting to and twenty-two pips below the 200-day. Three things stand out: the report that moved it had been published as settled consensus by a Japanese broker one hour and fifty-six minutes earlier; the day traded both sides of every 200-day reading we hold, a six-pip band from 158.50 to 158.56; and that broker now gives the same average at 158.56 on one page and 158.55 on another, neither naming the convention. A narrow Asian range in front of a 12:30 UTC US CPI print is an inventory statement, not calm.
Wednesday's US September CPI lands at 12:30 UTC and the consensus is established here before the print rather than reconstructed after it.
The headline is 3.6 or 3.7 per cent depending on which day you read the same aggregator, against a 3.4 prior. Core is read at 2.39, 2.4 and 2.5 against a 2.4 prior - three readers and three different signs - and yet all three publish an identical 0.2 core month-on-month. Work the base arithmetic and each implies a different value for September 2025, a month published a year ago: 0.21, 0.20 and 0.10. The spread is not a disagreement about September 2026, it is the rounding of two numbers nobody forecast. Score the monthly fields.
The Fed is about 70% priced for next week, the BOJ fully priced for 17–18 September, and the ECB is being priced for October.
Today's 12:30 print measures August — while Brent has fallen from $108.50 at 06:00 UTC to $103.76 at 11:45, two vendors agreeing, with no sourceable reason. Why the highest-probability CPI outcome resolves nothing.
At 14:00 UTC the New York option cut rolls off $7.26bn of USD/JPY notional, the University of Michigan publishes September sentiment against a 51.0 consensus, and Lagarde takes a stage in Paris.
CPI lands 90 minutes earlier. Two of the four are invisible to a calendar-fed news filter — and the core m/m consensus dispute we carried for two runs closes at +0.2%.
The Bank of Japan's own release has August corporate goods prices at +7.6% year on year against a 7.4% consensus — but July was revised up from +7.2% to +7.7%, so the beat is also a deceleration, and the month itself printed −0.2%. The largest contributor was non-ferrous metals at +43.3%, not petroleum. Plus Britain doubling its GDP consensus at 06:00 UTC for four pips, and a US CPI consensus three vendors cannot agree on.
