VERDICT: The tape has already priced a Fed that will neither cut nor hike, and it did that pricing in the belly, not the long end. Trade the reaction in 3s and 5s. The 30-year is a spectator.
1. THE MONTH THAT WASN'T July 31 marks, carried forward: 2Y 4.27 · 5Y 4.41 · 10Y 4.69 · 30Y 5.22 · 2s30s +95bp. This morning: 2Y 4.242 · 5Y 4.414 · 10Y 4.694 · 30Y 5.213 · 2s30s +97.1bp.
Four weeks. A doubled Treasury buyback announced August 19. A nineteen-year high in the long bond. A July FOMC that drew three regional-president dissents in favour of hiking. Net curve movement: two basis points. That is not calm. That is a market with no marginal buyer and no marginal seller, waiting on one man to move first.
2. THE BELLY DID THE REPRICING — NOT THE LONG END Trailing twelve months the US curve is up 17bp at 1Y, 72bp at 3Y and 5Y, 48bp at 10Y and 34bp at 30Y. The hump sits squarely in the belly. Twelve months of repricing went into the reaction function — how long the Fed stays restrictive — not into the fiscal term premium that occupies most of the commentary. 5s30s has flattened 38bp over the year to +80bp.
The consequence for today is where the convexity lives. A hawkish framing — reaccelerating inflation is not transitory, the task-force work points to a higher terminal — cheapens 3s and 5s and flattens 5s30s further. The AI-as-disinflationary-force framing Warsh ran in his November 2025 op-ed re-steepens it. In neither case is the 30-year the instrument: it is already 5.21% with a Treasury bid arriving underneath it on September 9.
3. THE BUYBACK IS A LIQUIDITY OPERATION, AND THE TAPE KNOWS IT Treasury doubled long-end liquidity-support buybacks from $2bn to at least $4bn per operation in the 10–20Y and 20–30Y sectors, effective September 9 through November 4. The rally on the announcement lasted a single session before yields retraced above their pre-announcement levels. Four billion dollars per operation against a debt stock north of $40tn is a market-function backstop, not duration removal. Trading it as quantitative easing is the standard error of this quarter.
The instrument to watch is not the 30-year headline. It is 20s30s, which is 0.8bp this morning. The twenty — historically the cheap point on the curve, and one of the two sectors Treasury is now buying — has fully converged to the long bond. When operations go live on September 9, that convergence is where the intervention shows up first. Mark it today.
4. THE INFLATION BACKDROP HE HAS TO TALK AROUND Heating oil +101% year to date. Gasoline +98%. WTI +45%. CRB +39%. This is six months of war in Iran working its way through the products complex, and the orthodox central-bank answer is that a supply shock should be looked through.
The difficulty is duration. Six months in, the shock is no longer sitting in crude — it is in the refined products households actually buy. A chair who has publicly committed to two percent, presiding over a sixth consecutive year of overshoot, with three of his own colleagues already voting to hike, has a narrow path between looking through this and validating them.
5. CREDIT IS NOT CORROBORATING ANYTHING IG broad at 80bp OAS, marginally tighter on the day. HY broad at 267. The quality ladder runs linear from AAA through BB — 42 / 59 / 67 / 99 / 156 — and then steps 126bp to B at 282 and 749bp to CCC at 1,031. Effectively the entire risk premium in the corporate market lives on the last two rungs.
The practical instruction is to stop reading a 267bp HY index as confirmation of any macro view. The information is in the 875bp gap between BB and CCC, and that gap is a dispersion story about issuer-level capital structure, not a statement about growth.
6. MUNIS AND THE ETF COMPLEX MUB −0.30z, SUB −0.28z. The muni block is doing nothing into the event, which is correct behaviour — the muni curve does not trade Jackson Hole, it trades the September reinvestment calendar and the fall new-issue slate.
Across the fixed-income ETF screen the only positive z-scores on the board are MINT at +0.55 and FLOT at +0.38. Everything carrying duration is modestly negative: GOVT −0.40, TLT −0.34, BNDX −0.72. That is textbook pre-event de-risking into floating rate. It also means positioning is light enough that a genuine surprise gets a full move rather than a half one.
WHAT TO DO WITH IT — The event risk sits in 3s and 5s, not 30s. Size the position where the convexity actually is. — 5s30s at +80bp is the cleanest single expression: hawkish flattens it, dovish steepens it, and both directions have room after a 38bp flattening over twelve months. — 20s30s at 0.8bp is the September 9 buyback tell. Record the level today and watch it through the first two operations. — Credit tells you nothing this morning. Do not treat HY at 267 as a confirmation of anything. — The CCC countdown stays open at 1,031. Six is drift; twelve is signal. — Prior editions referenced: "Warsh Trade Reverses as 30Y Cracks 5%" (12-May-2026); "The July Mark" (31-Jul-2026).
