Notes for Wed, Jun 17, 2026

Secured rates pushed SOFR 4bp above IORB into FOMC day, but the bill strip prices no cut; hold is baseline.

Into the decision

FOMC lands today and the baseline is a hold: IORB has been pinned at 3.65% since mid-May^[1] and nothing in the overnight tape forces a re-baseline. The call we'd flag isn't the statement, it's the funding. Secured rates firmed hard into mid-month: SOFR fixed 3.69% Monday^[2], up from 3.59% on the 10th^[3], and that's the last fixed print, Tuesday's drops at 8 AM, so we read into the decision one business day stale. The move left SOFR 4bp above IORB and 6bp above EFFR at 3.63%^[4], a spread that was flat-to-negative two weeks ago. Plumbing signal, not a policy-rate one.

Funding

This is broad, not a single-issue squeeze, and that's the load-bearing read. GCF traded 3.711% on Treasury collateral and 3.731% on MBS Monday^[5], BGCR and TGCR both fixed 3.67%^[6], tri-party and GCF moving together, not one venue. More telling: the SOMA specials that drove the early-June tape have faded. 912797UX3 went off at 198.7bp on the 9th^[7], but by the 16th the richest issue, 912797TM9, was down to 32.4bp^[8] from 142.9bp the day prior^[9]. If a collateral squeeze were the story, specials would be widening into the firming, not collapsing, so we read this as cash scarcity, and the cushion is gone. RRP ran $0.58bn Monday^[10], no buffer left to absorb pressure. Reserves at $3,081bn on the 10th^[11] sit only modestly off the May peak, which is the tension: repo behaves tight while reserves still look ample. We don't think that holds quietly into quarter-end.

Front end

Here's where we part with the easing narrative: the front end is not discounting cuts. The 2-year sat at 4.09% Friday^[12], above both IORB and effective funds, and the bill curve slopes up, 4-week 3.60%^[13], 3-month 3.63%^[14], 6-month 3.68%^[15], which prices no cut over the next six months, if anything a tilt the other way. 2s10s at +40bp^[16] is a term-premium story in the long end, not a Fed-easing story in the front. So we'd fade a knee-jerk rally that reads a dovish hold as the start of a cutting path. View breaks if the dots show a near-term cut the strip hasn't, or if Powell explicitly opens July. On funding, the trade is wrong if Tuesday's SOFR prints back below IORB at 8 AM, that would tell us the mid-month squeeze was technical and already reverting.
