4.97%
10-Year Treasury

4.65%
2-Year Treasury
2-year Treasury rose 2 bps to 4.65%, keeping the 10–2 curve spread flat at 32 bps and suggesting no immediate Fed pivot priced in.
3.63%
Fed Funds Rate
Fed funds rate unchanged at 3.63% as of early August, now stale by two weeks but consistent with a stable short-end through mid-September.
7,585.73
S&P 500

What it means for your shop

Lenders face renewed compression on production margins as the 30-year fixed climbs faster than long-duration Treasuries, signaling either a revaluation of mortgage credit risk or a rebalance of secondary market demand — either way, a tighter bid-ask and lower origination volume ahead unless rate locks accelerate.
