Mortgage and refinance rates in the US were higher on May 4, 2026, with the average 30-year fixed mortgage at 6.39% and the average 15-year fixed mortgage at 5.74%, according to WSJ Buy Side reporting based on Bankrate data (WSJ Buy Side, 2026). The short answer: rates could rise again this week if inflation concerns push Treasury yields higher or if Federal Reserve commentary sounds less willing to cut rates. These figures are as of May 2026; rates change daily, verify current terms with a licensed lender before deciding.

Why Rates Moved Higher

Mortgage rates do not move only because of the Federal Reserve. They tend to follow the bond market, especially the 10-year Treasury yield, because lenders price mortgages against the broader cost of long-term borrowing. The Federal Reserve publishes daily Treasury and other benchmark rates through its H.15 release, which is one useful way to monitor the rate environment (Federal Reserve, 2026).

On May 4, the market was still weighing inflation risk, energy-price pressure, and uncertainty about when the Fed might lower short-term rates. The federal funds rate does not directly set the 30-year mortgage rate, but it shapes expectations for inflation, bank funding costs, and investor demand for mortgage-backed securities.

Will Mortgage Rates Rise Again This Week?

A further increase is possible, but not guaranteed. The most likely trigger would be hotter inflation data, stronger labor-market data, or a rise in Treasury yields. If investors expect inflation to stay elevated, they usually demand higher yields, and mortgage lenders often respond by raising offered rates.

Rates could also hold steady or dip if economic data weakens, inflation expectations cool, or investors buy more Treasury and mortgage-backed securities. Freddie Mac’s research hub tracks broader housing and mortgage-market conditions, including weekly mortgage-rate trends that help show whether daily rate moves are becoming a larger pattern (Freddie Mac, 2026).

For buyers, the practical point is that “today’s rate” is only a snapshot. The rate you are quoted can differ from the national average based on credit score, down payment, loan type, points, property type, location, and debt-to-income ratio.

What Borrowers Should Do Now

If you are buying a home soon, ask lenders for same-day Loan Estimates so you can compare interest rate, APR, points, lender fees, and cash needed to close. A lower interest rate is not always the better deal if it requires expensive discount points or higher upfront costs.

If you are refinancing, run the break-even math before focusing on the headline rate. A rate-and-term refinance may make sense if the monthly savings recover closing costs within the time you expect to keep the loan. A cash-out refinance needs an extra layer of caution because it increases your loan balance and uses home equity as collateral.

If you are close to closing and the payment already fits your budget, a rate lock may reduce uncertainty. If you have more time, ask your lender about float-down options, lock periods, and what happens if rates move before closing.

Bottom Line

Mortgage and refinance rates were under 7% on May 4, 2026, but they were moving higher. Another rise this week would depend mostly on inflation signals, Treasury yields, and Fed expectations, not on any single mortgage-market headline.
