When the Fed Cuts Rates, Your Mortgage Rate Can Go Up. It Did After 4 of the Last 6 Cuts.

Will Mortgage Rates Go Down After a Fed Rate Cut?

Not reliably, and the lock desk proves it. Simply stated, the Fed controls an overnight rate that banks charge each other. A 30-year mortgage is priced off the 10-year Treasury yield plus the extra return investors demand to hold mortgage bonds. Both of those move on expectations about inflation and about what the Fed will do next, and they move weeks before the vote.

By the time the statement prints, the cut is already in the price. What moves mortgage rates on Fed day is what the Fed says about next time. If the message is "fewer cuts ahead," the 10-year yield rises, and the rate on your quote rises with it, on the same afternoon the Fed cut.

That's why the data looks the way it does. AmeriSave compared the average rate on loans borrowers locked in the seven days after each of the last six Fed cuts with the seven days before. On the cash-out refinance product, the average locked rate was higher after four of the six cuts. Across all loan products, it was higher after three of six. The moves were small, a few hundredths to a few tenths of a point, but the direction is the point. Figure 1 shows each cut.

The one clear exception was the November cut two years ago, when the average locked rate fell 0.18 of a point and lock activity rose 13.2% in the week. That's the exception that proves the rule. The other five did not behave that way. Table 1 lists all six.

The Buyer Who Waited for Fed Day

Picture a buyer with an accepted offer and a complete loan file. The Fed meets in nine days. A friend says wait, rates are about to drop. The buyer floats.

Fed day arrives. The cut lands as expected. The press conference signals a slower path from here. The 10-year yield rises that afternoon, mortgage-bond pricing follows, and the next morning the buyer's quote is a tenth of a point higher than it was the day the offer was accepted. The buyer locks anyway, because the closing date is fixed, and pays a little more every month for nine days of waiting.

The data shows this is not a rare outcome. It also shows what most borrowers actually do. In every window around every Fed decision, roughly half to two-thirds of borrowers locked within a day of starting their file. Lock activity moved less than 4% on average in either direction after cuts, holds, and hikes alike. The first 24 hours after a meeting swing in both directions, which makes them noise, not signal. Waiting for Fed day is a lottery ticket, and the expected value is negative. Locking is not.

Figure 2 shows how little lock activity moves after any type of decision, and Table 2 adds the speed-to-lock and lock-length figures.

Run the Numbers on the Typical Loan

The moves in Table 1 look tiny. On a real loan they’re not. The typical escrowed first mortgage in AmeriSave's data is about $195,360, and on a 30-year loan of that size each half-point of rate changes principal and interest by roughly $60 to $65 a month in the rate range borrowers have seen over the past two years. Scale that down and Table 3 shows what each post-cut move in Table 1 would have meant to a borrower who floated through Fed day instead of locking the week before.

These are illustrations of payment arithmetic, not rate offers, and they assume the borrower keeps the loan for its full term. Most people refinance or move sooner, so the lifetime figures are a ceiling. Even so, the monthly figures are the cost of nine days of waiting, and they land on a decision the borrower could have made for free.

Now the float-down. The average lock in the data runs about 43 days. If a lender charges a fee for the right to take a lower rate once before closing, compare that fee with the monthly saving at the improvement the float-down requires. A float-down that triggers at a quarter-point improvement is worth roughly $30 a month on the typical loan; if the fee is less than two to three years of that saving and you plan to hold the loan at least that long, it's reasonable protection. If the loan closes in three weeks, the fee rarely earns its keep, and a plain lock does the job.

What to Check Tonight

Check whether your file is complete enough to close inside a lock period. That's the test for locking, not the Fed calendar. A lock fixes your price for a set number of days; if the loan can close in that window, the lock is doing its job.

Check whether the fear of locking too high is what's keeping you floating. If it is, ask your loan officer to price a float-down. A float-down lets you take a lower price once if the market improves before closing, usually for a fee or a slightly higher starting price. Pay for the protection. Don’t pay for it by waiting.

Check the headline against the mechanism. If a story says the Fed's cut will lower mortgage rates, ask what the 10-year Treasury did that day. That number, not the Fed's, is the one on your quote.

The full report, After 4 of the Last 6 Fed Rate Cuts, the Rates Borrowers Locked Went Up, Not Down, walks through all 30 decisions across the past three and a half years, including holds and hikes.

Methodology

The figures come from AmeriSave's lock desk, counting only loans that locked a rate. Each window is the seven days before and seven days after 2:00 PM Eastern on the Fed's decision day, so both contain the same weekdays. Rate figures are simple averages on locked loans and move with product and borrower mix, which is why the cash-out product row is the primary comparison and all products is the check. No rate level is stated; only the direction and size of the change. The October meeting this year is excluded because its after window was still open. Data through October 29.

The Bottom Line

The Fed sets an overnight rate. Your mortgage prices off the 10-year Treasury and mortgage-bond spreads, which move on what the Fed says about next time, not on the cut itself. That's why locked rates rose after four of the last six cuts. Lock when your file can close inside the lock period, buy a float-down if the downside keeps you up at night, and ignore the calendar. AmeriSave's fixed-rate loan with a lock placed on the file's timing, not the Fed's, is how that discipline becomes a payment.
