Mortgage interest rates went up again today as markets remain sensitive to shifting threats during the Iran war.
The average interest rate on a 30-year, fixed-rate mortgage rose to 6.47% APR, according to rates provided to BW by Zillow. This is eight basis points higher than yesterday and 19 basis points higher than a week ago. A basis point is one one-hundredth of a percentage point.
We probably won’t see stable mortgage rates until an actual peace agreement is finalized. If mortgage rates keep moving up this week, we’ll likely see the highest rates of 2026 in the next several days. Why? Check out our analysis below the chart.

🤓 From the Nerds: Kate on Rates
📈 Why are mortgage rates moving upward?
The next major data drop that the Nerds are looking toward is the Personal Consumption Expenditures Price Index (PCE), which the Bureau of Economic Analysis is scheduled to release on May 28. This contains the Federal Reserve’s preferred inflation measure, and will likely sway mortgage rates.
The further inflation rises above the Fed’s target of 2%, the harder it will be for incoming Fed chair Kevin Warsh to push for a rate cut. If inflation grows too high, we might even be looking at the possibility of rate hikes in the fall.
Refinancing might make sense if today’s rates are at least 0.5 to 0.75 of a percentage point lower than your current rate (and if you plan to stay in your home long enough to break even on closing costs).
With rates where they are right now, you may want to start considering a refi if your current rate is around 6.97% or higher.
🏡 Should I start shopping for a home?
There is no universal “right” time to start shopping — what matters is whether you can comfortably afford a mortgage now at today’s rates.
🔒 Should I lock my rate?
Rate locks protect you from increases while your loan is processed, and with the market forever bouncing around, that peace of mind can be worth it.
🤓 Nerdy Reminder: Rates can change daily, and even hourly. If you’re happy with the deal you have, it’s okay to commit.
🧐 Why is the rate I saw online different from the quote I got?
Market factors beyond your control play a role in determining your personalized quote, as well as other factors such as:
Even two individuals with similar credit scores may receive different rates based on their overall financial profiles.
👀 Is the rate I see today guaranteed if I apply now?
While it’s possible, personalized rate quotes can fluctuate until you lock them in. Lenders adjust pricing multiple times daily in response to market changes.
