What Slowing MBS Growth Means for CA Homebuyers

Mortgage-backed securities issuance hit a four-year high in Q2 2026, but rising interest rates are cooling the market. Here's what that means if you're buying or refinancing in California.

The mortgage market had a strong start to the second quarter of 2026, with securities issuance reaching its highest level in four years. But as interest rates climbed through May and June, momentum faded — and that shift is worth paying attention to if you're in the market for a home.

Refinance activity took the biggest hit, with monthly volume dropping sharply in June. That's no surprise when rates rise — fewer homeowners see a financial benefit in refinancing their existing loans. If you've been sitting on the fence about a refi, the window may be narrowing.

On the purchase side, things looked more stable. Seasonal demand helped keep purchase mortgage activity moving in a positive direction, which is typical for the spring and summer homebuying season here in California.

What does this tell us? The market is still active, but it's becoming more rate-sensitive. Locking in a competitive rate sooner rather than later could save you significantly over the life of your loan.
