THE TAPE
Brent 97.92 pre-open after topping $100 overnight on U.S. strikes against Iranian tankers; WTI 93.03. Heating oil +115% year to date, gasoline +90%, copper 6.74 and still making highs. The crack spread is now the number central bankers are quoting. Diesel is the crunch Bloomberg is calling lasting.
Treasuries cheaper again, belly leading: 2Y 4.43 (+2.3), 3Y 4.51 (+5.0), 5Y 4.59 (+2.3), 10Y 4.81 (+1.4), 30Y 5.25 (+0.1). 20s30s inverted at −1 with the 20Y at 5.26. 30Y over 3M is 137, up 66 on the year; 5s30s at 66, down 45. Yesterday's three-year cleared into that belly [INSERT 3Y STATS: stop / tail / dealer take]. Tens today, thirties tomorrow.
Yen 153.30, another 70 pips overnight after Bessent's dare and 280 since Friday's close; z-score −0.87 against a 163.98 fifty-two-week high. JGB 10Y 2.88, 30Y 3.96. Gilts still the world's most expensive borrowing: UK 10Y 5.22, 30Y 5.84. Bund 3.41, OAT 4.30 (+7 on the day).
Credit prior close: IG 81, HY 265, CCC 1,055. IG 15+ at 103 over and 6.26% — the level confirmed on FRED at 1.03, 8 basis points wider than a year ago. The ETF gradient is heavy: MBS −0.20% pre-open, agencies −0.09%, short munis −0.06% at a −0.78 z. Cash is still at the front.
THE HOUSE
Two quotes from the Treasury Secretary in twenty-four hours. On the yen, at SMU Tuesday: "I am the house now… you can bet against me if you want." On yields, the buyback expansion was to cool "this fever that was building." This morning Treasury publishes the size of the first expanded operation. Two weeks ago the open question in this letter was whether it would disclose size at all. It is about to.
Read the two as one operation. A debt manager is now acting as a price-setter in two markets it does not control, and the mechanism in both is the same: swap one thing for another and hope the market takes the hint. In yen it swaps dollars for a currency whose central bank is about to hike. In Treasuries it swaps bills for bonds — a buyback funded with bill issuance pulls duration out of the market and puts cash-like paper in. That is a twist, not QE. No reserves are created; the duration just moves from the market's balance sheet to the Treasury's.
Here is the problem with the twist. The market has already run it. Bills-to-bonds is 66 basis points steeper than a year ago; 5s30s is 45 flatter. The front repriced for a Fed that hikes, the belly repriced for supply, and the long end has been the calmest sector on the curve. The 20-year at 5.26 against the bond at 5.25 tells you the sector Treasury is targeting priced the buyback the day it was announced. A bill-funded operation into a curve shaped like this adds bill supply where the front is already 85 basis points higher on the year and removes long duration where yields moved least.
So price the number against the week. Coupon supply is $58 billion of 3s done, tens today, thirties tomorrow — call it $120 billion gross. A first tranche in the low single-digit billions is a signal; a tranche that reads as a fraction of the week's long-end issuance is a policy. The bar for "the house" is whether the number is big enough to change the dealer's inventory math on the 30-year reopening tomorrow. If it is not, the operation is a headline that costs bill supply, and the long end will tell you by Thursday afternoon.
THE OTHER HOUSE
The yen dare is the more unusual of the two. The U.S. bought yen — the first purchases in three decades — and the Secretary says he has inside visibility on what the BOJ does next. For a Treasury desk the question is not the level. It is who funds the intervention and where the proceeds go. A Treasury that is buying yen and buying back long bonds is running two asset-swap books at once, and both are financed at the front of the U.S. curve. The BOJ decision is the next input; the carry unwind has already done 1,000 pips of the work since the summer high.
CREDIT ASIDE
High grade is still calm into the supply: 81 broad, 103 in the 15-plus bucket, unchanged. The 15-plus one-year change we ran yesterday holds at +8 on FRED's ICE series — the Koyfin change column on the maturity buckets is not stable day to day and the Dispatch will source that field from FRED going forward. CCC at 1,055, a new wide.
PRESSURE GAUGE
Carried from the September 6 Set-Up: Front-End/Policy PRESSURE · Term Premium/Long End PRESSURE · Credit CALM (CUSIP tiering) · Inflation PRESSURE · Growth/Labor STABLE · Cross-Asset ELEVATED · Composite ELEVATED. Term Premium stays at PRESSURE on the buyback: the operation is the confirmation of the reading, not the relief from it. Brent through 100 reinforces Inflation ahead of Friday.
