30-year mortgage rates increase - When should you lock? | Today's mortgage and refinance rates, June 11, 2026

Mortgage rates were mostly higher compared to last week, according to Bankrate data. Average rates for 30-year fixed, 15-year fixed and 5/1 ARM moved higher, while jumbo loan rates decreased.

Rates are still rising as the Iran War has no end in sight.Interest rates are oscillating, but staying on track, in response to this week’s economic data. The yield on the 10-year Treasury bond, which fixed-rate mortgages are set by, has risen to 4.54% as of June 5, around 10 basis points higher week-over-week. Average rates for the 30-year mortgage are hovering right around that 6.5% mark, where they’ve stayed since the start of May, though they’ve increased by half a percentage since the war in Iran started. Expect more of the same volatility until the war in Iran is resolved, many experts say.

“Rates have bounced around a bit depending on the current [temperature] in the Middle East,” says James Sahnger, mortgage planner at C2 Financial. “While the general ceasefire has remained intact, the outcome of a long-term agreement remains in flux, with no clear sign for a break-out move ahead.”

Rates as of 06/11/2026.

Today's average rate for the benchmark 30-year fixed mortgage is 6.55 percent, an increase of 0.03 basis points over the last week. This time a month ago, the average rate on a 30-year fixed mortgage was higher, at 6.47 percent.

At the current average rate, you'll pay $76.24 for every $100,000 you borrow. That's up $0.23 from what it would have been last week.

The average rate for the benchmark 15-year fixed mortgage is 5.92 percent, up 0.03 basis points over the last week.

Monthly payments on a 15-year fixed mortgage at that rate will cost approximately $100.74 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 5.69 percent, up 0.02 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 5.69 percent would cost approximately $69.57 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 6.69 percent, down 0.02 basis points from a week ago. A month ago, the average rate on a jumbo mortgage was lower, at 6.59 percent.

At the current average rate, you'll pay $0.16 per month in principal and interest for every $100,000 you borrow. That's down $0.16 per $100,000 compared to last week.

The average 30-year fixed-refinance rate is 6.69 percent, unchanged 0.00 basis points from a week ago. This time a month ago, the average rate on a 30-year fixed refinance was lower, at 6.68 percent.

At the current average rate, you'll pay $69.57 per month in principal and interest for every $100,000 you borrow. That's up $0.02 from what it would have been last week.

If you’re looking for the best deal on a new loan, here’s how to position yourself for the lowest possible rates:

• Grow your credit score: Grow your credit score by paying down debt, making your payments on time and not taking on new debt. 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 tells your lender that you mean business, and you'll be seen as less of a risk. You’ll get a better offer due to this decrease in risk.

A rate lock can prevent your mortgage rate from rising and weakening your buying power. 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.

Mortgage rates declined at the beginning of 2026, but changed course in March. The lowest rate for the year so far was 6.09% on February 18. Since then, rates have risen nearly 40 basis points and currently sit in the mid-6% range.

At the beginning of the year, Bankrate projected rates could fall as low as 5.7%. But no one had a war in Iran in the cards. This war has contributed significantly to rising oil prices and rising 10-year Treasury yields, which have driven rates up.

Where they’ll go the rest of the year depends on whether the war in Iran is resolved, as well as whether a slowing job market drives down housing demand.
