Why do mortgage rates fluctuate?

If you follow mortgage interest rates for a few days, you’ll likely notice that rates can fluctuate by a bit — or a lot — from day to day. Many factors drive these fluctuations. Here are some of the most common reasons why mortgage rates move frequently:

Employment patterns

The job market has a widespread effect on the nation’s overall economic health. When more people are out of work, the economy suffers. When more people are fully employed, the economy benefits. The employment rate is also an indicator of demand for mortgages. 

When more people are unemployed, fewer people will be looking to get a mortgage and buy a home — and that lower demand will push interest rates down. When the employment rate improves, demand for mortgages will likely keep pace. And as demand for mortgages rises, so will mortgage interest rates.

The bond market

Because bonds are a lower-risk type of investment, demand for bonds can increase when investors are wary of other investment vehicles, or fearful of the overall state of the economy. Increased demand for bonds causes their price to rise and their earnings — called their yield —  to fall.

When bond yields fall, consumer interest rates generally do as well, including mortgage interest rates. When investors feel more confident about the economy, demand for bonds declines, bond prices drop and yields rise. And interest rates tend to follow.

Federal Reserve System

"The Fed," as it’s commonly called, is the United States’ central bank. But it doesn’t actually set mortgage rates. Rather, multiple things the Fed does influence mortgage rates. For example, while mortgage rates don’t mirror the Fed funds rate — the rate banks apply when borrowing lending money to each other overnight — they do tend to follow it. If that rate rises, mortgage rates typically rise in tandem.

The Fed also buys and sells mortgage-backed securities, or MBS — a package of similar loans that a major mortgage investor buys and then resells to investors in the bond market. Rates tend to be lower when the Fed is doing a lot of buying. When the Fed buys fewer MBS, demand falls and rates will likely rise. Similarly, when the Fed raises the Fed fund rate, mortgage rates will also increase.

Global economy

Global banking systems and economies are closely interconnected. When economies in other parts of the world — especially Europe and Asia — experience a downturn, it affects investors and financial institutions in the United States. And, when foreign economies are doing well, they may attract more American investors — and divert those investment dollars out of the U.S. economy.

Those global influences contribute to the overall health of the U.S. economy. When the domestic economy is doing well, interest rates rise. And when the American economy falters, interest rates fall.

Current mortgage rates

After rising above 2.5% for four days last week, today’s average mortgage interest rate fell back down to just 2.375%.

Current 30-year mortgage rates

The current interest rate for a 30-year fixed-rate mortgage is 2.875%. This is down from last Friday. Thirty years is the most common repayment term for mortgages because 30-year mortgages typically give you a lower monthly payment. But they also typically come with higher interest rates, meaning you’ll ultimately pay more in interest over the life of the loan.

Current 20-year mortgage rates

The current interest rate for a 20-year fixed-rate mortgage is 2.500%. This is down from last Friday. Shortening your repayment term by just 10 years can mean you’ll get a lower interest rate — and pay less in total interest over the life of the loan.

Current 15-year mortgage rates

The current interest rate for a 15-year fixed-rate mortgage is 2.125%. This is down from last Friday. Fifteen-year mortgages are the second most-common mortgage term. A 15-year mortgage may help you get a lower rate than a 30-year term — and pay less interest over the life of the loan — while keeping monthly payments manageable. 

Current 10-year mortgage rates

The current interest rate for a 10-year fixed-rate mortgage is 2.000%. This is down from last Friday. Although less common than 30-year and 15-year mortgages, a 10-year fixed rate mortgage typically gives you lower interest rates and lifetime interest costs, but a higher monthly mortgage payment.

How Credible mortgage rates are calculated

Changing economic conditions, central bank policy decisions, investor sentiment, and other factors influence the movement of mortgage rates. Credible average mortgage rates and mortgage refinance rates are calculated based on information provided by partner lenders who pay compensation to Credible.

The rates assume a borrower has a 740 credit score and is borrowing a conventional loan for a single-family home that will be their primary residence. The rates also assume no (or very low) discount points and a down payment of 20%.

Credible mortgage rates will only give you an idea of current average rates. The rate you receive can vary based on a number of factors.

Fixed-rate vs. adjustable-rate mortgage

With a fixed-rate mortgage, your interest rate will remain the same for the life of your loan. At the beginning of your loan, you’ll know exactly how much total interest you’ll pay. But the rate can — and usually does — change with an adjustable-rate mortgage, or ARM. This means the total interest cost of the loan will also change.

ARMs tend to have introductory interest rates that are lower than fixed rates. But when the introductory period ends, the rate can move based on market factors.

Fixed-rate loans can be good for people who know they’ll be in their homes long term. ARMs may be a good option for people who don’t expect to stay in a home long, or who are confident they’ll be able to refinance into a fixed-rate loan when the introductory rate ends.

30-year vs. other terms

The repayment term is the number of years over which you’ll pay back your mortgage. Common terms for fixed-rate mortgages are 30 (the most common), 20, 15, and 10 years. 

Generally, the longer your repayment period, the higher your interest rate and total interest costs will be, but you’ll have a lower monthly payment. With shorter terms, you’ll usually get a lower interest rate and total interest costs, but a higher monthly payment.

Conforming vs. jumbo loans

Conforming loans are for amounts that fall below Fannie Mae and Freddie Mac’s established limits. Jumbo loans exceed that limit, which is $548,250 for a single-family home in 2021.
