London sold the dollar this morning and then bought it all back. The dollar index traded below 98.70 around 07:58 UTC, its lowest in over two weeks. USD/JPY, which had bottomed at 153.11 in the Tokyo session, extended into the 152 handle as London came in. EUR/USD pushed to about 1.1650. By 10:49 UTC EUR/USD was back at 1.1625 and by 11:35 UTC USD/JPY was back at 153.28. The whole move round-tripped inside three hours, and there is nothing on the US calendar at 12:30 UTC to explain what happens next. The dated event today is the 10-year note reopening at 17:00 UTC — and Treasury spends the same afternoon buying long-end paper back.
Seven consecutive 10-year auctions have cleared higher than the one before
The reopening at 17:00 UTC follows a straight ladder. January cleared at 4.173%, February 4.177%, March 4.217%, April 4.282%, May 4.468%, June 4.538%, July 4.580%, August 4.683%. That is seven auctions in a row each clearing above its predecessor, and 51 basis points of additional yield since January.
The cash 10-year is at 4.81% as we write, up about 1.7bp on the session and at its highest since October 2023. Against the 12 August stop of 4.683%, the market is asking for roughly 13 more basis points than it took four weeks ago. If today prints above 4.683% it makes eight in a row.
Note what that is not. It is not a failed auction, and nobody should read it as one. The 3-year on Tuesday stopped through by a tenth of a basis point with a 2.72 bid-to-cover against a 2.62 average — entirely normal demand, at eighteen basis points more money than the last one. That is the pattern worth holding: buyers keep showing up, and they keep showing up at a higher price. Those are two separate facts and conflating them is how people talk themselves into a crisis narrative that the tape does not support.
Treasury is on both sides of the long end today
Treasury announced that its maximum liquidity-support buyback size in the longer-dated nominal sectors goes from $2 billion per operation to at least $4 billion per operation, covering the 10-year to 20-year and 20-year to 30-year buckets, effective 9 September 2026 through 4 November 2026. Today is the first day. The stated reason is the volume of high-quality offers Treasury routinely receives in longer-dated operations — in its own words, consistent strong sponsorship.
So on the same afternoon, the US government sells 10-year duration at auction and doubles the size at which it stands ready to buy 10-to-20-year paper back. This is not quantitative easing and treating it as such will lose you money. Liquidity-support buybacks target off-the-run issues that have stopped trading well; the point is market function, not net duration extraction. The amounts are small next to the issuance calendar.
But the two things sharing an afternoon is not nothing either, because it changes what a soft auction would mean. In a week where the long end is the story, Treasury has just made the marginal bid for seasoned long paper twice as large. If the reopening still comes cheap into that, the demand question is a real one rather than a plumbing one.
The yield and the dollar are telling different stories, and that is the trade to watch
Ordinarily a 10-year at a three-year high pulls the dollar up with it. It is not doing that. The dollar index made a two-week low this morning; gold sits at $4,403.98, up 1.11% on the day; the yen is up roughly 3.8% over the past month. Higher yields and a weaker currency at the same time is the combination that says the market is pricing something other than a policy differential.
We are deliberately not going to name that something. There is a comfortable story available — the one about confidence in the dollar — and it is unfalsifiable on a one-day horizon, which is exactly why it is comfortable. What we will say is that the 17:00 UTC auction is one of the few places this week where that story gets a number attached to it. A stop-through with strong indirect participation says foreign official and fund money is still happy to own dollar duration at 4.7-something. A tail says it is not. That is a cleaner read on the same question than anything you will get from spot.
What this means for size, which is the only question you actually control
Today has no 12:30 UTC release. It has a small ADP weekly employment reading at 12:15 UTC, the New York option cut at 14:00, a 17-week bill auction at 15:30, the 10-year at 17:00, and the API crude inventory number at 20:30. The New York open at 13:00 UTC therefore arrives on top of nothing.
The practical consequence is that your afternoon has one real window in it and it is at 17:00 UTC, which is late in the European day and after most retail systems have already done their trading for the session. If you carry positions through the London close, you are carrying them through an auction. If your event filter only knows about 12:30 UTC releases — and most of them only know about 12:30 UTC releases — it will not see this at all.
The other half of it: the pin under EUR/USD is still there. This morning we said the 1.1615 and 1.1600 expiries for today's 14:00 UTC cut had London as the place they would break. London tried, took the pair to about 1.1650, and put it back at 1.1625 with two and a half hours left on the clock. That is a failed break, not a confirmed pin, and the distinction matters for how you size the next one. A range system that got stopped on the 1.1650 push and re-entered at 1.1625 has now paid the spread twice for a net flat market.
What this does not tell you
We do not know where the auction clears. Nothing above is a prediction of the stop, and the when-issued level is not something we have read at a source we trust today, so we have not published one.
The dollar-index level and the two-week-low framing come from a single vendor read at 07:58 UTC; other dollar measures were being described more dramatically elsewhere this morning, and we could not read those pieces in full, so we left them out. Treat “below 98.70” as one source's number.
The Tokyo range for USD/JPY (153.11–153.98) is one Japanese desk's, timestamped 07:10 UTC. A second Japanese desk described the pair reaching the 152 handle in early London at 06:32 UTC. Those are consistent if the first covers Tokyo hours only, which is how it is labelled — but we have not reconciled them tick by tick and you should not build a level off either.
Finally, the causal claim in the third section is the weakest thing here. Yields up and dollar down has a dozen explanations and we have offered none of them. The auction is a measurement, not an answer.
