30-Year Mortgage Rates Jump to a Summer High of 6.671% Going Into the Fed Meeting

30-year mortgage rates jumped 0.126 points to 6.671% and 15-year rates rose nearly as much, the sharpest weekly increases of our recent reports, one day before the Federal Reserve convenes to decide on rates.

Average home loan rates rose faster this week than in any of our recent reports, with the Federal Reserve's two-day meeting starting Tuesday. 30-year mortgage rates jumped 0.126 points to 6.671% and 15-year fixed mortgage rates rose 0.124 points to 6.200%, new summer highs for both. Jumbo, FHA, and VA mortgage rates all climbed by around a tenth of a point as well. The one average that didn't rise was the thinly quoted 3/1 ARM, which held steady at 5.808%.

The sharpest weekly rise of our recent reports

Conventional mortgage rates, national average APR since late March

Average APRs from MonitorBankRates.com's nightly collection, updated daily. The figures in the text and table below are average note rates, which run below APR.

In the four prior weeks, the 30-year average moved 0.006, 0.018, 0.042, and 0.042 points. This week it moved 0.126, to 6.671%, clearing the summer high it set just one report ago, and 15-year fixed mortgage rates matched the pace, up 0.124 points to 6.200%. In payment terms, this single week added about $33 a month to principal and interest on a $400,000 30-year loan, roughly what the previous month of increases added combined.

Adjustable-rate averages rose more slowly, which widened the gap between fixed and adjustable pricing. 5/1 ARM rates added 0.063 points to 5.991% and remain the lowest average we track, now 0.680 points under 30-year fixed rates; on a $400,000 balance that difference is about $178 a month, in exchange for a rate that can change after year five. 7/1 ARM rates rose 0.066 points to 6.132%, while 3/1 ARM rates held steady at 5.808%, the only average that didn't climb; that figure comes from the smallest ARM pool we track and deserves matching caution.

Jumbo and government-backed rates climbed just as fast

30-year jumbo mortgage rates rose 0.120 points to 6.759% and 15-year jumbo rates 0.102 points to 6.281%, keeping pace with conventional loans almost exactly. A borrower above the conforming limit is quoted about 0.088 points more than a conventional 30-year borrower on average, roughly the same difference as last week. Jumbo averages come from the smallest lender pools we track, and the exact figures deserve the usual caution.

Jumbo and FHA rates, national average APR since late March

Average APRs from the nightly collection. VA loans are omitted from this chart pending a data-quality fix in the nightly series; the VA table figures below are verified.

Government-backed loans joined the move. VA mortgage rates rose 0.120 points to 6.425% and FHA rates 0.109 points to 6.369%, the third straight week with the VA average above FHA. Both still sit below every conventional fixed average, and the rate an individual borrower gets depends far more on the lender and the loan file than on which program's national average is ahead. Buyers comparing local offers can line up Georgia mortgage rates against these national averages.

Mortgage rates moved before the Fed did

The Federal Reserve convenes Tuesday and announces its decision Wednesday afternoon, and futures markets ended last week pricing a quarter-point increase as more likely than not. Whether that expectation explains this week's jump is more than our data can show, but the order of events is worth understanding: fixed mortgage rates follow long-term bond yields, and those yields build expectations in ahead of an announcement rather than waiting for it. A week like this one, arriving before the Fed has done anything, is what that looks like from a rate table. It also cuts the other way; if Wednesday's decision matches what markets already priced, quotes may barely move on the news. The benchmark has held at 3.50% to 3.75% since December, three members voted for an increase in July, and our next report is the first that will show mortgage rates with the answer in hand.

What 6.671% does to the monthly payment

At 6.671%, principal and interest on a $400,000 30-year loan run about $2,573 a month, up roughly $33 from last week's average. Our mortgage calculator now works from this same live data: its example recalculates from the current MonitorBankRates average every time the page loads, drawing on rates published by more than 8,000 banks and credit unions, and it can load your state's average rate, property taxes, and insurance costs to build the full monthly payment rather than a sample one. Buyers weighing whether this market is worth entering at all can put real numbers on that question too: the rent vs buy calculator starts from today's live average and Census-based home values for your state and finds the year buying breaks even against renting. Week-to-week movement for every loan type is on our mortgage rate trends page.

Insurance quotes belong in the same afternoon

A week when rates add $33 a month to the average payment is a good week to remember the payment's other moving part: lenders require homeowners insurance before closing, and in many states the premium separates similar houses by more than this week's rate move does. Our MBR Home Insurance Burden Index ranks all 50 states by how heavily insurance weighs on homeowners, and Georgia buyers can compare carriers in our Georgia homeowners insurance guide. Quote the specific house while you shop the rate, not after.

The bottom line before Wednesday's announcement

Mortgage rates just posted their biggest weekly rise of our recent reports and enter the Fed's meeting at summer highs on every fixed product. Nothing about Wednesday is knowable in advance, but a borrower's defenses are the same either way: a rate lock protects a quote through the announcement, quotes from several lenders beat any single one, and behind the 6.671% average, 30-year offers in our data run from under 5% to above 9%. The spread between those lenders is worth far more than anything the calendar does this week.
