The average 30-year fixed mortgage rate in the United States is now 6.95 percent, up 19 basis points from a week ago, according to the weekly Freddie Mac series. The jump lands in the same week the Federal Reserve raised its policy rate for the first time in three years, and the timing is not a coincidence, even though the two rates are not connected the way they appear to be.

The Fed sets a short-term policy rate. The 30-year mortgage is priced by the bond market, off Treasury yields and mortgage-backed securities. The Fed's hike moved the short end of the yield curve on Wednesday, but the long end had been repricing for weeks on inflation expectations, oil prices, and government debt supply. What the weekly mortgage series just recorded is that repricing arriving at the kitchen table: the number a lender quotes to a buyer is now nearly a fifth of a point higher than the number quoted last week.

Why the mortgage moved with the Fed

The connection between the Fed's decision and the 30-year rate runs through the bond market rather than through any mechanical link. When the Fed signals that inflation is stubborn enough to require a hike, the whole fixed-income market reprices expectations for the years ahead. Treasury yields rise, mortgage-backed securities reprice against them, and lenders pass the move through in the rates they publish. The weekly Freddie Mac series catches the result with a lag, which is why the full move showed up in Thursday's release rather than Wednesday afternoon.

The magnitude matters. A 19-basis-point weekly move is several times the size of a typical week's change in this series, which usually drifts a few basis points at a time. The last comparable weekly jump in this data came during the rate spikes of the past few years, when the market was repricing inflation expectations quarter by quarter. A week this large says the market's view of the rate environment changed, not that it drifted.

There is also an important asymmetry to state plainly. Mortgage rates began rising before the Fed's announcement, because the bond market prices the expected decision ahead of time. That means some of Wednesday's hike was already in mortgage rates before Wednesday, and some of the market's post-decision repricing will show up in next week's number. The 24-basis-point move is the market's week of adjustment, not the full effect of the Fed's decision.

What 6.95 percent does to a buyer's math

The practical effect of the repricing is smaller than the headline number suggests, but it is real. On a $400,000 loan, the principal-and-interest payment at 6.95 percent is roughly $2,647 a month. At last week's 6.76 percent, the same loan cost roughly $2,596. The difference, about $51 a month, is the weekly repricing's direct bill to a borrower who locked before the move.

The larger effect is on the credit check. Lenders qualify borrowers at the rate they are actually being offered, and a fifth of a point of rate reduces the loan amount a given income qualifies for. A household that could qualify for $400,000 last week qualifies for a few thousand less this week, at the same income, on the same debt-to-income ratio. In a housing market where affordability is already the binding constraint, the rate moves the ceiling, and the ceiling just moved down.

For sellers, the repricing works in the other direction. Buyers whose ceiling moved down bid less, or stay out, and the inventory that has been sitting through the summer gets priced against a smaller pool of qualified demand. The fall selling season, which is already the slower half of the year, now opens at 6.95 percent instead of 6.76.

The bond market's version of the story

The 30-year rate is best understood as a summary of the bond market's view of the next several years. At 6.95 percent, the market is pricing in inflation that stays above target for longer, government borrowing that stays heavy, and a Fed that holds its new policy level through next year. Each of those judgments is contestable, and the weekly series will revise them as the data arrives.

The Fed's own projections and the bond market's pricing are not the same thing, and the gap between them is where the next mortgage-rate moves will come from. If inflation prints cooler than the market expects, the 30-year will fall without the Fed doing anything, because the bond market will reprice the future on its own. If inflation holds, the rate will stay where it is or drift higher, and the Fed's next decision will again arrive after the market has already priced most of it.

That is the frustrating asymmetry of mortgage rates for everyone involved: the Fed's decision is scheduled, telegraphed, and anticipated, and the mortgage market absorbs it in advance. The 24-basis-point weekly jump is the visible evidence that the absorption happened. The next move is already being priced, invisibly, in the bond market's daily churn, and it will show up in next week's number the same way this one did.

What comes next

The immediate question is whether 6.95 percent holds or drifts. The mortgage market will watch the same inputs the Fed named in its decision: the next inflation prints, oil prices, and the Treasury's borrowing schedule. Each is a data release away, and each will move the 30-year before the Fed's next meeting.

The deeper question is what a 7 percent mortgage environment does to the housing market's equilibrium. Buyers who bought through the low-rate years are locked into rates they will not voluntarily leave, which keeps inventory tight, which keeps prices elevated, which keeps the affordability problem intact even as rates rise. The rate is only half of the equation, and the other half, the supply of homes for sale, has not moved in response to anything the Fed has done.

For anyone shopping this week, the practical guidance is unglamorous. The rate you are quoted depends on the day you lock, not on the Fed's calendar. A decision made on the news of the hike is a decision made after the market has already priced it. The 6.95 percent in this week's data is the market's summary of the week that was. Next week's number is already being assembled, one bond trade at a time, and it will not wait for the next press conference.
