The Yen Didn't Buy It The BOJ hiked to 1.25 and the yen fell anyway. The relief bid in Treasuries gave it all back into the weekend.
The Bank of Japan hiked to 1.25 and signaled more. The yen fell 1.2% to 157.79. That is the whole morning. A central bank tightened and its currency sold off, which is the same sentence the Treasury market has been writing about Warsh since Wednesday. Yesterday's relief bid is gone: twos 4.74, tens 4.99, thirties 5.32, the levels of Wednesday's close to the basis point. Into a $7 trillion options expiry and a weekend, nobody wanted to be long.

THE BOARD
THE TAPE
Curve. Front end +7, long end +3. Twos 4.741 (+6.6), fives 4.853 (+6.7), tens 4.993 (+5.8), thirties 5.322 (+3.4). 2s10s 25, flattest of the week. Thursday's bull steepening lasted one session and gave back every basis point. Twos sit 74 over a 4.00 funds rate, which is the market pricing the October hike we argued for in October, Not December (https://dispatch.thebondbro.com/p/october-not-december) and then some.
Global. Gilts +7 at the ten, +15 at the two. The BOE scrapped long-end gilt sales Thursday; the market sent the bill to the front end, which is exactly the trade. OATs +9 against Bunds +1, OAT-Bund back over 100. Japan's curve did nothing on the hike: JGB tens 2.99, thirties 4.08. The market was already there.
Credit. IG 15+ OAS 98, tighter than 100 Thursday and 103 on Sept 7. Long credit keeps outperforming long Treasuries, which tells you the seller is duration, not risk. HY 270, BBB 96. CCC 1076 and quiet. Nothing here says stress.
Flows on the screen. SHV z +2.71, MINT +1.95. The front end is a parking lot again. Everything with duration is red on the day, and MUB carries the worst z-score on the tape at −1.71, the morning after Bloomberg reported a record outflow from the largest muni ETF. Bloomberg's other headline, money flowing into bonds at a record pace, is not a contradiction. Both are true: the money is going to bills and to 5% coupons in IG. It is leaving long tax-exempts.
Oil. WTI 103.15, +23% on the month, +80% on the year. Heating oil +143% YTD. This is what the Fed hiked into.
FX. USDJPY 157.79, +1.16%, z +2.28. The pair we told you to watch Thursday moved two big figures the wrong way for the BOJ.
THE EVENT
The BOJ delivered the hike and Ueda said more are coming. The yen fell anyway. A 25 basis point hike that was fully priced, to a policy rate still 275 basis points below Warsh's, is not a reason to own yen, and the market said so in about an hour.
Why this is a Treasury story: 158 is inside the range where the Ministry of Finance defended the currency in 2024, and Japan defends the yen by selling dollars, which means selling Treasuries. The largest foreign holder of US debt becomes a seller of the long end precisely when its own central bank is trying to tighten. That is the Treasury-side long end test, run from Tokyo instead of Washington. Thursday's note said the front end tests the chair and the long end tests the Treasury. Add: the yen tests both.
Watch 160. That is the line the MoF drew two years ago, and the only line the market respects.
THE ROUND TRIP
One week of Warsh, start to finish. Twos went from 4.63 to 4.74 and stayed there. Tens went nowhere. Thirties are lower than where they started. The curve flattened 9 basis points and the front end did every one of them.
That is Wednesday's post-FOMC note, The Short Got Paid, in one table. The hike got priced, then the next one, and the long end never blinked. It is also why One Hundred Basis Points Apart (https://dispatch.thebondbro.com/p/dispatch-morning-brief-6d3d) still matters: a market that will price 75 more of tightening at the two-year while leaving thirties flat is a market that believes the Fed will break something before it gets there.
THE DATA
Factory production unexpectedly shrank in August, and the decline was broad. One print is not a trigger for the Growth dial. Two would be. But a manufacturing contraction with crude at 103 and a chair saying underlying growth is higher is the stagflation shape, and the front end is priced for a Fed that hikes into it. Retail sales at 6% nominal with CPI at 3.4 is still consumption, and that is what the chair is leaning on.
The two-year at 4.74 does not care about the factory number. It will care about the next one.
THE ALABAMA TAPE
Enhanced 5s of 2056 (01065CAH6) last 5.19–5.22 against a 5.28 reoffer; enhanced 5s of 2066 (01065CAK9) 5.30 against 5.41. The backstopped tranches are still through issue with MUB at a −1.71 z-score, which is the whole tiering argument: the TIFIA-wrapped paper is trading like credit, not like duration. The first-lien 6s of 2066 have not printed on EMMA since pricing. That is the tranche that answers the question, and it is the one nobody has had to mark yet.
THE OTHER SIDE
Bloomberg's silver-lining piece is the bull case: 5% on tens, 5.3% on thirties, 6.3% on long IG, and record inflows chasing them. Allocators have waited two years for these coupons. If the factory number is the first of several, the front end is 50 basis points too high and 4.74 twos are the trade of the quarter.
Two problems. The inflows are going to bills, and the yen. A weaker yen at these levels is a forced seller of the long end, not a buyer. The bull case needs Tokyo to stay home.
PRESSURE GAUGE
The Dispatch Pressure Gauge · carried from Sept 16. Composite ELEVATED.
Scores carried. Cross-Asset stays GROWING with USDJPY at a +2.28 z-score; one more session above 158 and it moves to PRESSURE. Credit stays CALM on the CUSIP tiering and the 15+ bucket at 98. Growth stays STABLE on one factory print.
THE WEEK AHEAD
Monday–Wednesday. First post-FOMC Fed speakers. Anyone who says 'October' out loud moves the two-year. Flash PMIs Tuesday, the first read on whether the factory number was noise.
Thursday. GDP third estimate and claims. Claims are the only labor number that can move the Growth dial before the October meeting.
Friday. PCE. The inflation dial's trigger. Core at 2.4 with headline 3.4 is the relative-price problem the chair said must not broaden.
Standing. USDJPY 160. The first-lien Alabama mark. The Anthropic S-1. Month-end 2s/5s/7s supply the following week.
THE KICKER
A central bank hiked and its currency fell. Another central bank hiked and its curve flattened from the front. Both markets are saying the same thing: the hike is priced, the ending is not.
The Dispatch shows you the signal. The Vault shows you what it means.
