6.66%
30-Year Fixed Mortgage
30-year fixed mortgage reached 6.66%, up 8 bps in a single day and now pricing meaningful credit and volatility risk relative to Treasuries.
4.68%
10-Year Treasury
10-year Treasury held at 4.68%, up only 1 bps — the long end of the Treasury curve is stable, but mortgages are repricing faster.
4.23%
2-Year Treasury
2-year Treasury steady at 4.23%, 1 bps higher, keeping the front end of the curve flat relative to 10-year at 45 bps — signaling stubborn Fed rates expectations.
3.63%
Fed Funds Rate
Fed Funds Rate unchanged at 3.63% (as of June 1), holding below the 10-year yield and leaving no imminent cut signals to anchor long rates.
7,489.72
S&P 500
S&P 500 closed at 7,489.72, up on the day — risk appetite remains despite higher mortgage costs, suggesting market-wide repricing rather than credit stress.
