How Do Lower Interest Rates Impact Reverse Mortgages?

Dan Hultquist
When rates are in the news, reverse mortgages should be, too. Fed cuts don’t directly set mortgage rates—markets do. Because HECM guidelines key off Treasury yields (especially the 10-year CMT), even small dips can increase a borrower’s proceeds. Case in point: with a 2.50% margin, the expected rate moved from 6.69% to 6.55% in a few days—boosting one client’s available funds by $9,075. If you or your borrowers are considering a reverse mortgage, lower rates may unlock more cash or line of credit, translating into real flexibility and peace of mind in retirement.

How Do Lower Interest Rates Impact Reverse Mortgages?

Most of the time, my friends and family glaze over the minute I bring up interest rates. But lately? Everyone’s listening. Rates are in the headlines, and homeowners want to know: what does this mean for me—especially if I’m considering a reverse mortgage?

Let’s break it down.

Do Fed Rate Cuts Lower Mortgage Rates?

Not exactly. When the Federal Reserve announces a rate cut, many assume mortgage rates will drop in lockstep. But that’s not how it works.

In fact, mortgage rates often rise after a Fed rate cut. Here’s why:

  1. Mortgage rates track the 10-year Constant Maturity Treasury (CMT), not the Fed funds rate.
  2. The 10-year CMT is influenced by broader economic factors, not just Fed policy.
  3. Markets move on expectations. It’s not what the Fed does today—it’s what they signal for tomorrow.
  4. The market “prices in” cuts early. By the time a cut is official, rates may have already adjusted.

For example, in the 30 days leading up to this week’s 25 basis point cut, the 1-year Treasury yield had already fallen 29 basis points, and the 10-year had dropped 28. The market saw it coming.

Why Lower Rates Matter for Reverse Mortgages

Here’s the good news: when interest rates decline, reverse mortgage applicants usually benefit. That’s because Home Equity Conversion Mortgages (HECMs)—the federally insured reverse mortgages—rely on both long-term (10-year CMT) and short-term (1-year CMT) Treasury rates.

Here are some key concepts:

  • A borrower’s “expected rate” (lender margin + 10-year CMT) helps determine how much the borrower can initially borrow.
  • The lower the expected rate, the more proceeds available.

For example, when I first began writing this article on Friday, September 12th, a 2.50% lender margin plus the weekly average 10-year CMT provided an expected rate of 6.69%.

The result? One borrower’s available funds increased by $9,075—just from a small rate shift.

What This Means for Homeowners

Lower rates don’t just make headlines—they can directly increase the cash or line of credit available through a reverse mortgage.

If you or your clients have been thinking about exploring a reverse mortgage, now may be a smart time to look closer. Even small movements in rates can open up more options. That could mean more financial flexibility, more proceeds, and greater peace of mind in retirement.
