Wednesday, August 26, 2026 — and the mortgage market this week is in a holding pattern that I’d describe as “tense calm.” Everyone’s waiting for Friday. That’s when Federal Reserve Chair Kevin Warsh takes the stage at Jackson Hole for his first major policy speech since taking over. The bond market isn’t moving much right now because no one wants to be caught on the wrong side of whatever he says.
10-Year Treasury: Holding at 4.66%
The benchmark 10-year Treasury yield has been pinned in a tight range all week — opening Monday around 4.68%, dipping to 4.63% Tuesday, and settling back to roughly 4.66% this morning. That’s meaningful for you as a Marin County borrower because the 30-year mortgage rate moves in lockstep with the 10-year. Right now the spread between the 10-year and a conventional 30-year mortgage is running about 175–185 basis points, which puts conforming rates in the 6.40–6.55% range for well-qualified buyers, and jumbo pricing (which dominates in Marin) is actually tighter — closer to 6.25–6.40% for strong files through our wholesale lenders.
That spread between Treasuries and mortgage rates had been running as wide as 250+ bps during the 2023–2024 volatility. The fact that it’s compressed to under 185 bps tells me lenders are competing harder for loan volume. That’s a quiet win for borrowers.
Bond Market: Treasury Buybacks Are Real and They Matter
Something that hasn’t gotten enough mainstream coverage: the U.S. Treasury has quietly doubled its bond buyback operations on longer-dated securities over the past few weeks. Buybacks reduce the supply of bonds in the market, which pushes prices up and yields down. It’s a technical support mechanism, and it’s one of the reasons the 10-year yield hasn’t blown out toward 5% despite the deficit numbers.
I’m not going to pretend this is a guarantee of lower rates. But it does mean there’s a structural buyer in the market supporting long-duration bonds. If Warsh signals Friday that the Fed is comfortable with current policy and isn’t looking to hike, you could see the 10-year pull back toward 4.50% — which would be meaningful for mortgage rates. A 15–20 bps drop in the 10-year flows directly into borrower pricing.
Equities: S&P 500 Consolidating After Strong Run
The S&P 500 is essentially flat on the week — up maybe 0.3% from Monday’s open, hovering just below recent all-time highs. Tech is steady, financials are slightly positive (bank stocks like it when the yield curve steepens, which it has been doing gradually). No big selloff, no breakout — just consolidation while everyone waits on Warsh.
For the real estate market, a healthy equity market matters. Marin County buyers are disproportionately funded by stock options, RSUs, and concentrated tech positions. When the market is up, buyers feel flush. When it’s down, we see deals blow up at the last minute because a borrower’s asset verification comes in lower than expected. Right now the equity market is supportive of transaction volume.
Jackson Hole Friday: What Warsh Actually Needs to Say
Kevin Warsh is a different animal than Jerome Powell. He’s been more hawkish historically, more focused on price stability, and less willing to telegraph moves far in advance. That’s actually fine — the market has had 18 months to digest the post-Powell transition and knows what Warsh is about.
What the bond market needs to hear Friday is simple: no new hikes, and some acknowledgment that the disinflationary trend is intact. That’s it. If Warsh says those two things in any form, expect a Treasury rally and mortgage rate relief heading into September. If he sounds hawkish — if he signals the door to rate hikes isn’t fully closed — expect yields to spike back toward 4.80%+ and mortgage rates to follow.
My read: he’ll be cautious but not alarming. The jobs data has been softer, PCE inflation is running near target, and there’s no political upside to rattling the market right now. I’m cautiously optimistic about Friday.
What This Means for Marin County Buyers and Sellers Right Now
Inventory in Marin remains tight. We’re seeing active listings in the 350–400 range countywide, which is low historically. The properties that are priced correctly — meaning priced for today’s market, not last year’s peak — are moving in under three weeks. The ones that are sitting are overpriced by $200K–$400K and sellers haven’t accepted that yet.
For buyers: if you’re pre-approved and sitting on the sidelines waiting for rates to come down dramatically before jumping in, I’d challenge that thinking. Rates at 6.25–6.40% on a jumbo loan for a $2M Marin home translate to a principal and interest payment around $12,400–$12,700/month on 20% down. If rates drop to 5.75% — which would require a significant shift — that payment falls to roughly $11,700/month. That $700/month difference is real, but so is the risk that a rate dip brings 40 more buyers back into competition on the same house you want. I’ve watched that movie before.
For sellers: buyers right now are sophisticated and rate-sensitive. They’re doing the math. Price your home with that in mind and you’ll sell faster than anyone else on the block.

🗺️ Marin City-by-City Snapshot
- Tiburon — Waterfront and view homes still command their premium in the $3M–$5M+ range, but off-water listings are negotiating for the first time in years.
- Belvedere — Thin as always; a handful of listings, mostly jumbo, and buyers here are far less rate-sensitive than the rest of the county.
- Mill Valley — The busiest submarket in Marin right now, with a median around $2.55 million and more genuine choice than buyers have had in a long time.
- Sausalito — Condos and houseboats sit longer than hillside single-family; financing for floating homes stays specialty, so line up your lender before you write.
- Corte Madera — Steady and family-driven; well-priced homes near the schools still move quickly.
- Larkspur — Downtown and Greenbrae-adjacent inventory has loosened modestly, with more room to negotiate on the older housing stock.
- Kentfield — School-district demand keeps a firm floor under prices even as days on market stretch out.
- Greenbrae — One of the better value plays in central Marin right now if you can be flexible on updates.
- San Rafael — The county’s volume leader at roughly $1.2M–$1.8M, and expanded inventory is creating real openings for move-up buyers.
- San Anselmo — Charming older homes; budget for inspections and expect sellers to entertain repair credits.
- Fairfax — Most affordable entry point in central Marin, and the first-time buyer pool here is the most rate-sensitive in the county.
- Ross — Very few listings, very high price points, and almost every deal is a jumbo or portfolio conversation.
- Novato — The most inventory in the county and the most negotiating room; strong candidate for a seller-paid rate buydown.
- Marinwood / Terra Linda — Mid-century inventory with solid value per square foot; renovation financing fits well here.
- Strawberry — Condo and townhome supply where HOA review can make or break the loan, so check it early.
- Stinson Beach / Bolinas — Coastal fire-zone properties where insurance drives the deal; specialty lending required, and get an insurance quote before you go into contract.
- Point Reyes / Inverness / Nicasio — Rural west Marin with acreage, wells, and septic in play; specialty loans, not standard conforming, and slower to structure.
💡 What Should Marin Buyers Do Right Now?
- Lock if you’re in contract. With hike odds near two-thirds and CPI landing September 11, the risk between now and the FOMC meeting skews higher, not lower. Floating into that is a gamble, not a strategy.
- Ask for a seller-paid buydown instead of a price cut. At 3.2 months of inventory, sellers are listening — and a seller-funded 2-1 buydown usually improves your payment more than an equivalent price reduction, for the same money out of their pocket.
- Use the leverage on inspections and credits. Seven weeks on market means you can write a normal offer with normal contingencies. That wasn’t true in Marin two years ago.
- Get pre-approved before you tour, especially west of the ridge. Fire-zone, acreage, and floating-home properties need lenders who actually do those loans. Learning that after you’re in contract costs you the house.
