Notes for Wed, May 27, 2026

Iran-relief bid gave the front a leg; we faded it, 12th consecutive 5Y tail and Cook/Waller framing point to a higher-for-longer reprice through Thursday's PCE.

The take

We're fading today's front-end rally into Thursday's PCE. Session opened on the continuation of the Iran-deal bid, Brent down to $96.70^[1], 10yr at 4.47%^[2] on the relief tape, but the back-half told the real story: Brent rebid to $99.50^[3] as Hormuz language stayed unresolved, and the Cook commentary stacked on top of the Waller pivot is the wall the front has to clear. We don't think today's bid survives a confirming inflation print.

OIS now prices zero ease beyond June with 45% terminal tightening odds by late October^[6], the kind of repricing that either gets validated or gets faded. Our read is validate: core PCE is tracking 3.3% YoY in April per the sell-side cut and 6mo annualized at 3.8% (highest since Jun '23)^[4], with forecasters running 0.28% MoM^[5]. If that holds, the geopolitical-relief bid in 2s gives back fast. Cook's hikes-on-the-table framing^[7] reads as standard guardrail to us in isolation, but stacked with Waller killing the easing bias^[8] it's two committee voices steering against the cut path in the same week.

Alternate read we considered and rejected: a clean Hormuz reopening plus a sub-0.25 core PCE print would put us in genuine bull-flattener territory. The market itself isn't priced for that, Brent rebid to $99.50 says the cleaner outcome isn't believed, and the household-vs-establishment payroll divergence Tchir flagged^[9] is the labor-side option, not the inflation-side. View breaks if core PCE prints 0.20 or below MoM and Hormuz traffic actually normalizes inside the week. Assumes Treasury holds May refunding bill pace and Indirects stay engaged at the 7Y.

Auctions and the curve

Two-year tapped 4.071%^[10], highest stop since February, with internals merely fine. Dealers took 12.3%^[11], bid-to-cover flat YoY, no signal of fresh supply stress at the front. The five-year did the work: priced at 4.182% with a 0.1bp tail^[12], the 12th consecutive 5Y tail and the longest streak on record^[13]. Foreign bid carried it, with Indirects 74.85% (highest since May '25)^[14], while dealers absorbed 12.8%^[15] of the belly. We read this as persistent indigestion masked by foreign carry demand, not real-money conviction at 4.18%.

5s30s closed near 81bp^[16] on one quote and 84bp on another^[17], tightest in roughly a year either way. The flattener is front-end driven, not duration strength; the curve mechanic is consistent with OIS hike repricing, shorter tenors cheapen relative to wings as policy stays restrictive longer. SOMA SecLend confirmed the technical: belly issue 91282CQL8 (T 3.750 04/30/28) clipped 13.4 bp through floor on $6.96B accepted yesterday^[18], and the bill 912797SU2 (B 11/27/26) printed 30.1 bp special on $6.05B today^[19]. Borrow demand in the belly aligns with the auction indigestion.

Money markets and month-end plumbing

SOFR fixed at 3.63% on 5/26^[20], two basis points below IORB at 3.65%^[21]; EFFR at 3.62%^[22]. No stress in the funding stack, SOFR-IORB hasn't inverted in the way that would force a rethink on reserves adequacy, and reserves at $3,129B per the 5/20 H.4.1^[23] are comfortably above the operational floor we've been watching. GCF UST repo printed 3.671% on 5/26^[24], up six basis points from 3.611% Friday^[25], typical month-end firmness, not a stress signal.

RRP take-up has whipsawed mid-week, $24.9B on 5/20^[26], $3.3B on 5/21^[27], under $1B Friday, $1.79B on 5/26^[28]. We read the pattern as mid-month coupon-settlement plumbing rather than a regime change in MMF cash demand. TGA stood at $825.6B as of 5/22 close^[29], the 5/26 Daily Statement hasn't ingested, so the month-end refill picture waits for tomorrow's update. Treasury yields for 5/26 likewise haven't filed in our H.15 mirror; the freshest cite tuples we have are 5/22 (DGS10 at 4.56%^[30], DGS2 at 4.13%^[31], DGS30 at 5.07%^[32], DGS5 at 4.27%^[33]), and intraday color is doing the work for today's tape.

Through to Thursday

Positioning into the open: we'd be modestly short 2s heading into PCE, not size. The trade is binary on the print and the front end already gave back a meaningful chunk of Friday's rally into the 4.071% 2Y stop today. 7Y on Thursday is the cleaner read, if Indirects step back from the 74.85% level that carried the 5Y, the belly cheapening becomes structural rather than carry-masked and the curve flattener trade extends. If Indirects hold and PCE comes in soft, we're wrong about both the direction and the source.

Falsifications we're tracking: core PCE ≤0.20% MoM AND oil cracking back below $90, that combination breaks the front-end-cheapening view. A 5s30s widening through 90bp on a bull-steepening tape says the curve flatness wasn't really about the front. And if reserves drop materially on the next H.4.1 with SOFR-IORB inverting again, the month-end firming we're calling typical needs to be reframed.
