30-year mortgage rates rise - To buy or wait? | Today's mortgage and refinance rates, March 30, 2026

Mortgage rates jumped according to Bankrate data. The average rates for 30-year fixed, 5/1 ARMs and jumbo loans moved higher.

Rates keep climbing due to warfare in Iran and rising oil prices. While there has been mention of a ceasefire, nothing has materialized yet. On top of that, the damage to infrastructure and oil has already been done, which could have lingering impacts on the economy for some time to come.

But why does this affect mortgage rates? The 10-year Treasury bond yield responds to changes in the market, and fixed-rate mortgages are tied directly to this yield.

“The 10-year U.S. Treasury rate seems to have shifted to a higher level and has stabilized there over the past few days. However, the uncertainty over the Iran conflict and the resulting impact on consumer prices — oil, food, medicine, etc. — may drive inflation expectations higher and interest rates higher across the board,” says Sean Salter, associate professor of finance at Middle State Tennessee University.

If inflation rises, the chance of another rate cut from the Federal Open Market Committee (FOMC) recedes. At the last FOMC meeting on March 17 and 18, the committee projected one more rate cut of 25 basis points to come in 2026. The FOMC meets next on April 28 and 29. March's employment and inflation data, which should show the impact of the war in Iran, will likely have an impact on the Fed's meeting.

Mortgage rates change all the time. Sometimes they can swing wildly from day-to-day and lender-to-lender. That’s why Bankrate created the Mortgage Rate Variability Index. This index changes every week to show how much rates are fluctuating and the range of rates between lenders.

Rates as of 03/30/2026.

The average rate you'll pay for a 30-year fixed mortgage today is 6.56 percent, an increase of 0.20 basis points over the last week. This time a month ago, the average rate on a 30-year fixed mortgage was higher, at 6.07 percent.

At the current average rate, you'll pay $76.32 for every $100,000 you borrow. That's up $1.57 from last week.

The average rate for a 15-year fixed mortgage is 5.89 percent, up 0.18 basis points over the last week.

Monthly payments on a 15-year fixed mortgage at that rate will cost approximately $100.55 per $100,000 borrowed. That may put more pressure on your monthly budget than a 30-year mortgage would, but it comes with some big advantages: You'll save thousands of dollars over the life of the loan in total interest paid and build equity much faster.

The average rate on a 5/1 ARM is 5.71 percent, up 0.10 basis points over the last week.

Adjustable-rate mortgages, or ARMs, are mortgage loans that come with a floating interest rate. To put it another way, the interest rate can change periodically throughout the life of the loan, unlike fixed-rate mortgages. These types of loans are best for those who expect to sell or refinance before the first or second adjustment. Rates could be materially higher when the loan first adjusts, and thereafter.

Monthly payments on a 5/1 ARM at 5.71 percent would cost approximately $69.72 for each $100,000 borrowed over the initial five years, but could climb hundreds of dollars higher afterward, depending on the loan's terms.

The average jumbo mortgage rate is 6.62 percent, up 0.20 basis points from a week ago. Last month on the, the average rate on a jumbo mortgage was lower, at 6.29 percent.

At the current average rate, you'll pay $1.58 per month in principal and interest for every $100,000 you borrow. That's up $1.58 compared with last week.

The average 30-year fixed-refinance rate is 6.78 percent, up 0.15 basis points from a week ago. Last month on the, the average rate on a 30-year fixed refinance was lower, at 6.59 percent.

At the current average rate, you'll pay $69.72 per month in principal and interest for every $100,000 you borrow. That's up $0.10 from what it would have been last week.

To get the best mortgage ratem follow these steps to strengthen your application:

• Grow your credit score: Paying down debt, making all payments on time and putting a stop on new debt will help you boost your credit score. A higher score will unlock a better rate, with the best rates going to those with a score of 780 or higher.
• Shop around: It pays to shop around mortgage offers because rates and fees can vary so much by lender. By comparing offers from different lenders, you could save thousands of dollars.
• Lock your rate: When you get the rate you want, lock it. This can help you take advantage of dips in the market. Ask your lender if they offer a float-down option, which will allow you to adjust your rate downward if market rates dip lower.
• Put more money down: A higher down payment lowers the loan amount, which means less risk for your lender. You’ll get a better offer due to this decrease in risk.

In volatile economic times, locking your mortgage rate can protect you if rates move up. Many homebuyers choose to lock their rates after their offer on a home has been accepted, but you can lock sooner than that if you think rates will rise before you find a home. Before you lock your mortgage rate, ask your lender:

• How much does it cost to lock a rate? Many lenders offer free rate locks, but only for a certain time frame. Ask about any rate lock fees or lock extension fees.
• How long does the rate lock last? The typical initial rate lock lasts 30 to 60 days, though some lenders do 90-day initial locks. Beyond that, you’ll need to ask for an extension.
• If rates drop, will I be able to take a lower rate? Some lenders allow you to take a lower rate after you lock in, known as a float-down lock. If your lender offers this, be sure you understand the details, including if there’s an additional fee or rate change threshold.

Mortgages rates have been steadily decreasing since Q4 2025, with the 30-year rate averaging 6.18% for the first two months of 2026. For the same period last year, rates were hovering above 7%.

Still, rates have been slow to come down and they may not drop much further. Bankrate projects that the average rate for 2026 will be around 6.1%. Rates may drop as low as 5.7%, but could also rise to 6.5% throughout the year.

One thing is for certain: if rates go lower, it will open up more opportunities for people to buy or refinance.
