Flatteners into CPI: the front-end is doing the work, the long end is along for the ride

Post-NFP hawkish repricing drove 10s2s to 38bp, the 1y bill is bleeding specialness into Tuesday's $50B sale, and we stay short the belly.

The take

Today's tape is hawkish front-end, not duration. The 2Y at 4.16% on the desk's morning marks is the highest since Feb 2025^[1], and 10s2s slumped to 38bp on June 5^[2], from 49bp ten sessions earlier on May 26^[3]. That is not term premium doing the work. The Fed's 3y10y model term premium has actually rolled off from 0.86 on May 19 to 0.75 on May 29^[4], so the curve flattening is Fed-path repricing: roughly 50bps of cuts taken out by year-end after Friday's payroll beat^[5]. We sit short the belly into Wednesday; if CPI prints core services hot, the 2-5y has more room to give than the long end at current term-premium levels.

Auction tell — the load-bearing read

The cleanest signal on dealer positioning is in SOMA SecLend. The 5/13/27 1y bill traded at 147.6bp special on Monday with $1.45B accepted^[6], dealers short the WI ahead of Tuesday's $50B 52-week sale, hedging into a hawkish CPI tail. More telling, the May 2036 10y on-the-run decelerated from 61.9bp on June 3^[7] to 23.8bp Monday^[8], long-end duration concession is being absorbed as fast as it's being created. Setup says front-end auction risk is real, long-end is digesting cleanly.

Money markets otherwise unchanged. SOFR 3.63%, EFFR 3.62%, IORB 3.65%^[9], GCF repo 3.66 MBS / 3.66 UST on June 5^[10]. TGA at $826B per the desk's morning read after a $19B draw^[11], with reserves at $3.01tln after a $52.7bn weekly drop^[12]. No funding stress, no repo squeeze, no auction tail risk from cash scarcity.

Geopolitics fade, but the falsifier sits in oil and core services

Iran-Israel pause is holding but fragile, Trump halted strikes on Iran proper, Israel continues Lebanon ops^[15]. Brent at $97.83 (+5%) on Houthi Red Sea ban^[13] is the air pocket; sustained dual-chokepoint disruption is the tail we'd have to repay. View breaks if (a) CPI core services prints sub-0.20% MoM, GS at 0.17%, DB at 0.22%^[14], in which case 2Y has 10-15bp of clean room to rally and the flattener unwinds, or (b) crude clears $100 and holds on confirmed Bab-el-Mandeb closure, which forces front-end cuts further out and bear-steepens via the inflation impulse rather than the duration bid we'd want. Assumes Treasury holds bill pace into July refunding; a coupon upsize surprise at the next quarterly announcement reshapes the trade.
