Friday, August 21, 2026 — Stocks are recovering today after a rough week, with the S&P 500 up 0.4% and the Dow gaining 264 points on stronger-than-expected US business activity data. But here’s what matters for homebuyers: the bond market didn’t follow. The 30-year Treasury yield hit 5.273% today — near its highest level since 2007 — which is why mortgage rates are staying stubbornly elevated despite the equity rally. A stock market bounce doesn’t move mortgage rates. Bonds do.

Today’s Mortgage Rates — August 21, 2026

Loan TypeRate (Today)
30-Year Fixed6.50%
15-Year Fixed6.00%
5/1 ARM6.25%
30-Year Jumbo6.787%
30-Year FHA6.086%

Rates are essentially flat from yesterday. The 15-year fixed at 6.00% remains attractive for buyers who can handle the higher monthly payment in exchange for building equity faster — particularly relevant in Marin, where buyers are often equity-rich and looking to accelerate payoff.

Why Stocks Rallied but Rates Didn’t Drop

Today’s stock market bounce is being driven by a strong US business activity reading — the fastest pace of growth in over four years. That’s actually bad news for mortgage rates. Strong economic data signals the Fed doesn’t need to cut, which keeps pressure on bond yields. The Treasury’s decision to increase long-end buybacks provided some temporary technical support for bonds, but investors are reluctant to chase that rally because buybacks don’t fix the underlying fiscal picture. Bottom line: don’t wait for stocks to rally and assume mortgage rates will follow. They move on different signals.

What This Means for Marin County Buyers

The Marin County market has shifted into a more measured pace heading into late summer. The typical home value sits around $1.45 million, with median sale prices closer to $1.2 million — and homes are taking more time to sell than during the peak years. That’s actually good news for serious buyers: you have more room to negotiate and fewer bidding wars to navigate.

At today’s 30-year rate of 6.50% with 20% down on a $1.2M home, you’re looking at a principal-and-interest payment of roughly $6,063/month. That’s not cheap, but with Marin inventory still limited and demand from San Francisco tech commuters remaining steady, prices haven’t softened dramatically. Waiting for rates to fall to 5% before buying could mean competing against a wave of buyers who’ve been on the sidelines even longer than you.

What This Means for Marin County Sellers

Historically, the stretch from late August through September is one of the best windows to list in Marin. Spring buyers who missed out earlier in the year re-engage, and competition from new listings is lighter than spring. If your home is priced right and shows well, you may be surprised how quickly it moves — even in a higher-rate environment.

The key in today’s market is price discipline. Homes that chase spring’s wishful comps and then sit for 60+ days are creating the “declining values” narrative in the data. Homes priced at real market value — accounting for today’s rate environment — are still getting clean offers.

Rate Outlook: The Bond Market is the Story

The 30-year Treasury yield touching highs not seen since 2007 is the defining story for mortgage rates right now. Investors are pricing in a “higher for longer” Fed, a resilient economy, and ongoing Treasury supply concerns. For mortgage rates to move meaningfully lower, we’d need to see either a significant economic slowdown, a clear inflation downtrend, or a shift in Fed guidance — none of which appear imminent.

That said, rate volatility can work in your favor if you’re ready to act. When rates dip — even briefly — locking quickly can save you real money over the life of a jumbo loan. Being pre-approved and ready to lock on short notice is a real tactical advantage in this market.

Jumbo Loan Note for Marin Buyers

Most Marin County purchases require jumbo financing (loans above the conforming limit of $1,149,825 in most CA counties). Today’s 30-year jumbo rate of 6.787% is slightly higher than the conforming rate — which is typical. But jumbo guidelines have loosened compared to prior years, and for well-qualified buyers with strong assets and income, jumbo loans are very accessible.

If you’re buying in Tiburon, Belvedere, Ross, or other high-value Marin towns where even starter homes clear $1.5M, you’re almost certainly in jumbo territory. We structure a lot of these loans and know how to find the best execution for your specific profile.
