Jumbo Loans Are Surging — What It Means for CA Homebuyers

Non-agency mortgage-backed securities hit near-record levels in Q3 2026, driven largely by jumbo loan activity — a strong signal for California's high-value real estate market.

California's real estate market has always leaned heavily on jumbo loans — after all, when median home prices in many parts of the state easily exceed conforming loan limits, jumbo financing isn't a luxury, it's a necessity.

That's why the latest mortgage market data caught my attention. Non-agency mortgage-backed securities issuance surged nearly 11% from Q2 to Q3 of 2026, reaching one of its highest production levels in nearly two decades. The biggest driver? Prime jumbo loans, which jumped over 21% quarter-over-quarter and made up more than half of all prime residential MBS collateral.

What this tells us is that investor appetite for high-quality jumbo mortgages remains very strong. When Wall Street is actively buying up jumbo loan securities at this pace, it keeps the jumbo lending market competitive and liquid — which is good news for California buyers financing higher-priced homes.

In practical terms, this means jumbo loan products should remain accessible and competitively priced. If you're purchasing or refinancing a home above the conforming loan limit in California, now is a great time to explore your jumbo loan options.
