Mortgage Spread Compression Is Doing What Rate Cuts Haven't: Moving Pending Sales Higher
With the 30-year spread over Treasuries near 2.01%, pending home sales have climbed to 422,120 nationally — a meaningful year-over-year gain that the Fed deserves little credit for.
The Federal Reserve has not cut the federal funds rate since December 2024, yet something in the mortgage market is quietly working in buyers' favor. The spread between the 30-year fixed mortgage rate and the 10-year Treasury yield has narrowed to approximately 2.01 percentage points, a level that is keeping the average 30-year rate near 6.60% even as underlying Treasury yields remain elevated. The result: total pending home sales have risen to 422,120, compared with 396,652 at the same point last year — a gain of roughly 6.4% year over year.
That pending sales figure matters more than closed sales for gauging current demand, because it reflects contracts signed but not yet settled. Buyers signing contracts today made their decisions at current financing costs, not six months ago. The uptick suggests that 6.60% is, for a meaningful slice of buyers, a workable rate — particularly when compared with the 7.00%-plus environment that characterized much of 2023 and early 2024.

Why Spreads Matter More Than the Fed Funds Rate Right Now
Mortgage rates are not set by the Fed. They track the 10-year Treasury, with a spread added to compensate investors in mortgage-backed securities for prepayment risk and market uncertainty. During periods of elevated volatility — as in 2022 and 2023 — that spread widened well past historical norms, briefly reaching 3.00 percentage points or more. The Mortgage Bankers Association has documented spread levels over time, and a return toward the long-run average near 1.70 to 1.80 points would push rates meaningfully lower even without any change in Treasury yields.
At 2.01 points, spreads remain above that historical average, but the directional move has been significant. Investors in agency MBS — primarily Fannie Mae and Freddie Mac securities — appear more willing to accept tighter compensation as volatility expectations moderate. The MOVE Index, which tracks implied volatility in the Treasury market and closely correlates with mortgage spreads, has declined from peaks above 160 in late 2023 to a range below 100 through much of early 2025.
For originators and brokers, the practical implication is that rate-and-term refinance volume remains limited — the vast majority of existing borrowers carry sub-5% rates they are unlikely to abandon — but purchase demand has a floor that is not entirely dependent on Fed action. If spreads continue compressing toward 1.80 points, the effective 30-year rate could approach 6.20% to 6.30% with no change in monetary policy.
The practical takeaway for operators: do not wait on Fed meeting calendars to forecast purchase volume. Monitor the 10-year Treasury yield alongside spread behavior in the agency MBS market. If spreads tighten another 20 basis points, that alone represents a larger rate improvement than any single Fed cut at the current pace of policy — and it could happen without a single FOMC vote.
