Mortgage rates today: May 21, 2026

Rates are daily averages based on Better Mortgage data, not APRs, and vary by borrower.

Mortgage rates on May 21, 2026, are averaging 6.67% for a 30-year fixed loan. The 15-year fixed is running around 6.22%, and the 7/6 SOFR ARM is priced at approximately 6.33%.

Rates pulled back this week after spiking to a 9-month high of 6.75% on Monday, a move driven by the U.S.-Iran conflict and aggressive bond selling, before recovering Wednesday on reports that a peace agreement may be nearing completion.

Within this context of this national average, your actual rate will depend on your credit score, down payment, debt load, and loan size. National averages provide a useful benchmark, not a quote.

What's moving rates right now

Mortgage rates don't exist in a vacuum. They follow the bond market, specifically the yield on 10-year U.S. Treasury notes, and that yield moves based on how investors read the economy.

When inflation data comes in hotter than expected, bond yields typically rise, and mortgage rates follow. When economic uncertainty spooks investors into the safety of bonds, yields fall and rates can soften with them. The relationship isn't instant or perfectly correlated, but over time, it's the most reliable lens for understanding why mortgage rates are going up or down.

On Monday, rates surged to their highest level since July 2025, up roughly 0.75% since the start of the U.S.-Iran conflict, as investors sold bonds aggressively in response to war-related uncertainty and oil price pressure. Elevated oil prices feed through to inflation expectations, and higher inflation expectations push bond yields up.

On Wednesday, rates settled down after newswires reported that U.S. and Iran negotiations are approaching a final peace framework. Bond markets rallied strongly on the news, pulling the 10-year Treasury yield noticeably lower.

The volatility of this week is a useful reminder that rates can move meaningfully in either direction based on geopolitical developments, not just domestic economic data.

How bond markets affect your mortgage rate

The 10-year Treasury yield functions as a benchmark because mortgage-backed securities, the bonds that fund most home loans, are priced relative to it. When investors demand a higher return on Treasuries (usually because they're worried about inflation or geopolitical risk eroding returns), mortgage lenders respond by raising rates to keep their products competitive.

This is what determines mortgage rates at the macro level. Your individual rate is then layered on top: your credit score, debt-to-income ratio, and loan-to-value ratio all adjust the final number up or down from that baseline.

30-year vs. 15-year vs. ARM — which makes sense today?

The right loan type depends on how long you plan to stay in the home and how you want to manage monthly cash flow.

A 30-year fixed at 6.67% offers the lowest required monthly payment for a given loan amount. You pay more in total interest over the life of the loan, but the lower payment gives you flexibility. If rates fall significantly — and this week's volatility shows they can move quickly — you could refinance to access lower rates.

A 15-year fixed at 6.22% carries a higher monthly payment but comes in 45 basis points below the 30-year rate. You build equity faster and pay substantially less in total interest over the life of the loan. It makes the most sense for buyers who can comfortably handle the higher payment without straining their budget.

A 7/6 ARM at 6.33% starts with a fixed rate for seven years, then adjusts twice a year. Today's ARM rate sits 34 basis points below the 30-year fixed, a meaningful but not dramatic spread. ARMs make sense for buyers with a defined, shorter timeline, someone who knows they'll sell or refinance before the initial fixed period ends. They carry more uncertainty: rate caps limit how much the rate can move each year, but the payment will change. Given the current geopolitical environment and rate volatility, that uncertainty deserves extra weight.

Use the mortgage calculator to compare monthly payments across loan types at today's rates before deciding.

Should you lock your rate or wait?

Rate lock timing is one of the most common questions buyers face — and this week's rate swings illustrate exactly why.

A rate lock freezes your interest rate for a set period (usually 30 to 60 days) while your loan moves through underwriting. If rates rise during that window, you're protected. If rates fall, you've missed the lower rate unless your lender offers a float-down option.

Many lenders offer float-down options that allow you to lock a rate and then move to a lower rate should it drop materially before closing. These aren't universal, and they typically come with conditions. Ask your lender about the specifics before counting on one.

The conventional guidance: If you're within 60 days of a closing date, lock your rate. This week showed how quickly rates can spike — 0.75% increase can increase monthly payments as well as long-term interest costs.

How to get a lower rate than today's average

The national average is built from millions of loan scenarios. It shows trends but not necessarily your specific rate. Here's what actually moves your individual rate:

Credit score. This is the single biggest lever most borrowers have. The difference between a 680 and a 760 score may translate to a meaningfully lower rate on the same loan. Check current mortgage rates with your actual score before assuming you'll pay the average.

Down payment. A higher down payment reduces the lender's risk, which is reflected in pricing. Getting from 5% down to 20% down doesn't just eliminate private mortgage insurance (PMI) — it can also lower your interest rate. Learn how to shop around for mortgage rates once you know your down payment target.

Loan size. Jumbo loans (above the conforming limit of $832,750 in most of the U.S. for 2026) are priced differently than conforming loans. Know which category your loan falls into before comparing rates.

Points. Paying discount points upfront — essentially prepaying interest — lowers your rate for the life of the loan. Whether this makes financial sense depends on how long you plan to keep the loan. Use a refinance calculator to model break-even timelines if you're weighing this option.

Whether rates are negotiable. Most borrowers don't realize that mortgage rates are negotiable — at least to some degree. Getting quotes from multiple lenders and comparing them directly gives you negotiating leverage. Better's fully online process lets you see a personalized rate without a full application.

Frequently asked questions

What are mortgage rates today on May 21, 2026?

The 30-year fixed mortgage rate is averaging 6.67% as of the most recent market data. The 15-year fixed is at 6.22%, and the 7/6 SOFR ARM is at 6.33%. These are national averages. Your rate will vary based on your credit profile, loan size, and down payment.

Are mortgage rates going up or down right now?

Rates pulled back this week after spiking sharply on Monday to their highest level since July 2025. The recovery came Wednesday after reports emerged that U.S.-Iran peace negotiations are nearing a final draft agreement, which calmed bond market selling. Rates remain elevated compared to earlier in 2026 and can shift quickly based on geopolitical developments.

Should I lock my mortgage rate today or wait?

If you're within 60 days of a closing date, locking today eliminates uncertainty. This week showed how fast rates can move. The spike to 6.75% on Monday and the recovery on Wednesday happened within 48 hours. Many lenders offer float-down options that allow you to lock a rate and then move to a lower rate should it drop materially before closing.

Why did mortgage rates spike this week?

According to recent market data, the U.S.-Iran conflict triggered aggressive bond selling, which pushed 10-year Treasury yields to their highest level in more than a year. Because mortgage rates track Treasury yields, they moved sharply higher, rising roughly 0.75% since the war began. Elevated oil prices also added to inflation expectations, which put additional upward pressure on rates. The partial recovery on Wednesday came on peace negotiation reports.

If I have a 720 credit score and 10% down, what rate can I realistically expect?

A 720 credit score puts you in solid territory — well above the minimum for most conventional loans. With 10% down, you'll likely pay PMI, but your rate should be at or slightly below the national average for a well-qualified borrower. The fastest way to know your actual number is to get a personalized quote. With Better's online process, a personalized quote takes about three minutes and doesn't affect your credit.

Is now a good time to refinance if I have a rate from 2023?

If you closed in late 2023 when rates were near cycle highs, current rates may represent meaningful savings depending on your original rate and remaining loan balance. Use a refinance calculator to model your break-even — divide your closing costs by your monthly savings to see how many months it takes to come out ahead. If you're staying in the home long enough to clear break-even, refinancing can make sense.

Does it make sense to get an ARM when rates might come down?

A 7/6 SOFR ARM at 6.33% is priced 34 basis points below the 30-year fixed today, a real but modest spread. An ARM makes sense if you have a defined timeline and are confident you'll sell or refinance before the fixed period ends. The risk is staying past the fixed period if rates don't fall as expected. This week's volatility is a reminder that rate direction is difficult to predict. Factor in rate caps and your actual timeline carefully before choosing an ARM over a fixed loan.

What's the difference between an interest rate and APR?

Your interest rate is the base cost of borrowing, the percentage used to calculate your monthly principal and interest payment. APR (annual percentage rate) is broader: it includes the interest rate plus lender fees, expressed as an annualized cost. APR is a better apples-to-apples tool when evaluating offers from multiple lenders. The rates in the table above are interest rates, not APRs.

The national average is a useful starting point, but it's not your rate. Your actual mortgage rate depends on your credit profile, how much you're borrowing, and the lender you work with. Better's fully online process lets you see a personalized rate in minutes — with no impact to your credit score.
