Mortgage rates aren’t stuck where they are by accident — they’re shaped by a number called the “spread,” the gap between the 10-year treasury yield and the average mortgage rate. Understanding that spread is the key to understanding why rates haven’t dropped dramatically, and why they likely won’t anytime soon.
If you’re house hunting or thinking about listing anywhere from St. Augustine to Nocatee to the rest of St. Johns County, you’ve probably wondered why rates seem stuck in a holding pattern. There’s real logic behind it, and once you see the numbers, today’s rates may look a little less discouraging.
The Relationship Between Treasury Yields and Mortgage Rates
Mortgage rates don’t move independently. For more than 50 years, they’ve tracked closely with the 10-year treasury yield, which reflects how investors feel about the broader economy.
- When the economy looks strong, that yield tends to rise over time
- When the outlook feels shakier, it tends to ease
- The two numbers aren’t identical — the difference between them is known as the “spread”
That spread currently averages about 1.76 percentage points historically. A wider spread pushes mortgage rates higher than the treasury yield alone would suggest, while a narrower spread keeps rates closer to it.
Why Rates Probably Won’t Drop Much Further
A few years ago, economic uncertainty pushed that spread as high as 3.19 points in 2023 — one of the widest gaps in recent memory. Since then, it’s narrowed to around 2.01, just above the long-term average.
Here’s what that means in real numbers, based on today’s 10-year treasury yield of 4.68%:
- If the spread were still as wide as it was in 2023, rates would be pushing close to 8% right now
- With the spread narrowing to its current level, today’s rate sits around 6.69%
- If the spread matched its exact long-term average, rates would land closer to 6.5%
That last comparison matters most. Today’s rate is only about a quarter of a point away from where the long-term average spread would put it. Housing analyst Logan Mohtashami has pointed to improved mortgage spreads as one of the more encouraging housing developments of the year — a sign that most of the relief a shrinking spread could offer has already worked its way into rates.
What This Means If You’re Buying or Selling
For buyers, this explains why waiting for a dramatic rate drop may not pay off — most of the room for improvement from the spread has already been used up. For sellers, it’s a reminder that buyers adjusting to today’s rates are still active, since the alternative (rates near 8%) never fully materialized.
- Rates are unlikely to swing sharply in either direction without a major economic shift
- The spread narrowing is largely responsible for rates being lower than they could have been
- That same narrowing limits how much further rates can realistically fall
FAQs
Why aren’t mortgage rates dropping even though people keep saying they will? Rates are closely tied to the 10-year treasury yield plus a gap called the spread, and that spread has already narrowed close to its historical average, leaving less room for rates to fall further.
Is now a bad time to buy because rates are still kind of high? Not necessarily — today’s rate is well below where it would be if the spread were as wide as it was in 2023, so waiting for a dramatically lower rate may mean waiting on something unlikely to happen soon.
How do I know what a rate like this actually means for my monthly payment? The best way to know for sure is to talk with a local lender who can run the numbers based on your specific loan amount, credit profile, and down payment.
Bottom Line
Rates aren’t where many buyers and sellers wish they were, but they’re meaningfully better than they could have been if the spread hadn’t narrowed.
