In the ever-fluctuating world of mortgage rates, staying informed is key. As of Wednesday, August 26, 2026, the bond market is experiencing intraday volatility, making it challenging to track day-over-day changes. Lenders typically publish their initial rates based on bond prices around 9:30-10:00 AM ET, but these can shift if bonds move significantly. Yesterday, however, bonds improved enough in the afternoon that many lenders offered lower rates, providing a brief window of opportunity for prospective homebuyers.

NerdWallet’s daily mortgage rates are calculated as an average of the published annual percentage rate (APR) with the lowest points from a sampling of major national lenders. This methodology ensures a reliable snapshot of the market. Our daily market updates provide a fresh reading and analysis every business day, so you can see where mortgage rates stand right now—not last week. We track the 10-year Treasury yield and Federal Reserve policy to explain why rates moved and where they may head, offering expert economic analysis.

Our editorial standards are designed to deliver plain-language explanations with real payment math, offering direct lock-or-float guidance without jargon or fluff. The rates shown above are the current rates for the purchase of a single-family primary residence, based on a 45-day lock period. Given the current volatility, it’s more important than ever to stay updated and consider locking in a rate if you find a favorable one. Keep an eye on the bond market and consult with your lender to make the most informed decision.
