Bankrate's daily 30Y print stayed flat at 6.49% — but that's misleading. The action was intraday in bonds: the 10Y hit 4.63% overnight (a fresh 12-month-plus high), then partially recovered on rumors the U.S. agreed to lift Iran's oil sanctions, closing the day near 4.47% after the round trip. MND's MBS desk titled the morning recap "Early Gains and Losses on Conflicting War Headlines." The structural news, though, was the MBA officially flipping its forecast to project a 2027 Fed rate HIKE (not cut) — a substantive recalibration that formalizes last week's Goldman/BofA repricing and lands as official trade-group consensus rather than a bank-research note. CEO Bob Broeksmit publicly framed rates as "stubbornly high for the foreseeable future." Translation: 6.45–6.50% isn't a wave, it's the new shelf.
Tuesday brings housing starts, Wednesday brings existing-home sales. With the MBA forecast officially flipped and the 10Y bouncing around 4.45–4.63 on Iran headlines, the path is more volatile than directional. Watch 4.50% as the new floor (it used to be a ceiling); a clean break below opens 4.40 and gives rate sheets 5–8 bps of breathing room. The TWO shareholder vote is TOMORROW — whatever the outcome, it shifts the IMB consolidation narrative without moving rates directly. The real rate catalyst is whether the Iran sanctions rumor turns into action; if it does, expect a 10–15 bp 10Y rally; if it doesn't, the next leg above 4.50 starts.
6.49% ties the 90-day high (range 5.98–6.49, avg 6.33), sitting 16 bps above the 90-day average and 7 bps above the 30-day average of 6.42. Second consecutive session at the high water mark — the first time we've held the top of the range two days running this cycle. For the 2023-vintage 7%+ refi cohort, the conventional math is about $200/mo back on a $400K loan at 7.25% → 6.49%. UWM's Refi '86 incentive (86 bps through June 30) still stacks on top for broker-channel files. Gov-loan rates held last weekend's spike (FHA 6.18, VA 6.19) — no further damage, but no relief either.
Two segments today. First — active pipeline with rate sheets from May 15 or earlier: call them today. The Friday/Saturday spike held over the weekend; quotes from before that are now 13–18 bp stale, and any borrower who got a written number then is operating on misinformation. Second — refi 2023-vintage 7%+ cohort, broker-channel — Refi '86 still has 43 days until June 30; the "here's your side-by-side comparison" call is fresh and actionable. Do this today: pull every locked file with a rate-sheet date on or before May 15 and confirm the lock is intact OR push the close date to give yourself flexibility while the Iran sanctions news plays out. Don't relock anything today before Tuesday morning's 10Y open — wait for overnight clarity, because the Iran headline cycle could move the tape 10 bps either direction in 24 hours.
