Treasury curve flattens as ten-year holds near four-decade lows; mortgage rates stable

Long bonds are pricing in persistent low growth while short rates remain elevated, leaving the refinance window narrow.

The call

The 10Y–2Y Treasury spread sits at 0.38pp — the curve is flat.

6.52%
30-Year Fixed Mortgage
30-year fixed holding at 6.52% leaves borrowers underwater on incentive to refinance unless the 10-year breaks below 4%.
4.43%
10-Year Treasury
10-year Treasury at 4.43% reflects market skepticism on sustained growth—a headwind for rate-sensitive refi volumes.
4.05%
2-Year Treasury
2-year at 4.05% shows near-term policy expectations remain anchored despite the steeper 10-2 slope in nominal terms.
3.63%
Fed Funds Rate
Fed funds at 3.63% (late May) is now a backward-looking anchor; market is pricing continued accommodation.
7,420.1
S&P 500
Equities at 7,420 reflect risk-on sentiment that supports low long-bond yields—but doesn't move the mortgage needle in borrowers' favor.
The 10-year at 4.43% is the real story for lenders: it signals markets expect a prolonged soft landing, which limits refi upside and keeps borrowers locked in at current origination rates around 6.52%. Expect volume pressure until the curve normalizes.
