What moved rates

Monday brought more of the same. Selling resumed at the open, a midday recovery took back part of the loss without changing the direction, and the daily 30-year index closed up another 5 basis points at 7.17%. That is six consecutive increases and the highest reading since January 2025.

This morning the 10-year Treasury moved above 5%, trading near 5.03%. Three forces are stacked in the same direction. Oil remains elevated with the Saudi East-West pipeline still shut, which keeps feeding the energy line that drove August inflation. Inflation itself has now run above the Federal Reserve’s 2% target for five years. And a wave of corporate borrowing, much of it from companies financing AI infrastructure, is competing for the same pool of capital that buys long-term government debt. This is not only a U.S. story: Australian benchmark yields reached their highest since 2011 and Japanese yields are trading near 3%.

The Federal Open Market Committee began its two-day meeting this morning and announces its decision Wednesday at 2:00 p.m. Eastern, along with the updated projections that show where members expect rates to go from here. Interest-rate futures moved again overnight and now price the odds of a quarter-point increase around 92%, up from roughly 85% yesterday. There are no economic releases today; retail sales arrive Wednesday morning ahead of the decision. This page will carry the actual outcome, the vote and the projections on Thursday morning.

What it means if you are…

Buying. The daily index at 7.17% is what reflects current pricing, and it has moved higher every session for more than a week. The survey figure of 6.76% at the top of this page was collected before almost all of that, so it is a benchmark for direction rather than a quote you can act on. If you are in the market, the useful move is knowing your maximum comfortable payment rather than your maximum approval amount, because those two numbers drift apart quickly when rates climb this fast.

Refinancing. Rate-and-term refinancing is off the table for nearly everyone at these levels. Two things still deserve attention: whether you carry an escrow shortage from a Florida insurance increase, which can be addressed without touching your rate, and whether your rate would ever justify a refinance if you also removed mortgage insurance. Both depend on your own numbers rather than the market’s. The refinance savings check on this site will show what a change would actually accomplish.

Under contract. The decision and the projections land tomorrow afternoon, and the projections are often what moves rates in the hours after. Locking today removes that exposure entirely. Floating through it keeps the chance that the market has already priced in more than the Committee delivers, at the cost of being exposed if the projections point to further increases. Your closing date and any days remaining on an existing lock decide which risk you can carry, so ask your lender today what a lock costs, what an extension costs, and when the current one expires.

What a $400,000 loan looks like at today’s average

At 6.76% on a 30-year fixed, principal and interest on a $400,000 loan is approximately $2,597 per month (6.76% ÷ 12 = 0.563% monthly rate, over 360 payments). At the daily index reading of 7.17%, the same loan runs about $2,707 — roughly $110 more per month, or about $39,600 across the full term. These figures exclude property taxes, homeowners insurance, flood insurance, mortgage insurance and any association dues; the actual monthly obligation will be greater.

Florida note

The gap between the conventional and jumbo readings above is unusually narrow right now, 11 basis points, which is worth knowing if your purchase price sits near the conforming loan limit. Loans at or below that limit follow Fannie Mae and Freddie Mac pricing; a dollar above it becomes a jumbo loan with different pricing, different reserve requirements and often a different appraisal standard. Most of Florida uses the standard national limit, while Monroe County carries a high-cost limit because of Keys home values. The Federal Housing Finance Agency announces next year’s limits in late November, and they are based on home price data through the third quarter, so a purchase that closes in January may qualify at a higher limit than the same purchase in December. If your price is within a few thousand dollars of the line, that timing is worth raising with your lender before you set a closing date.
