The Federal Reserve is expected to hike rates one more time. What that means for you

Experts predict the Federal Reserve likely will approve a quarter-percentage-point interest rate increase this week.

This 0.25 percentage point hike will mark the 10th time the Fed has raised its benchmark interest rate over the past year or so, the fastest pace of tightening since the early 1980s. 

Consumers are now paying more to borrow while still grappling with a high cost of living — causing them to feel increasingly worse off financially.

Even though the Fed’s rate-hiking cycle has started to cool inflation, higher prices are causing real wages to decline.

Real average hourly earnings are down 0.7% from a year earlier, according to the latest reading from the U.S. Bureau of Labor Statistics.

Because incomes have not kept pace with inflation, household budgets are squeezed, causing more people to lean on credit just when interest rates have been rising at the fastest pace in decades.

“People are racking up debt and that’s troublesome,” said Tomas Philipson, University of Chicago economist and the former chair of the White House Council of Economic Advisers.

Here’s a breakdown of how increases in the benchmark rate have been affecting the rates consumers pay on the most common types of debt:

Most credit cards come with a variable rate, which has a direct connection to the Fed’s benchmark rate.

After a prolonged period of rate hikes, the average credit card rate is now more than 20% on average — an all-time high, while balances are higher and nearly half of credit card holders carry credit card debt from month to month, according to a Bankrate report.

“Yet another rate hike from the Fed means today’s sky-high credit card interest rates will rise even further in the very near future,” said Matt Schulz, chief credit analyst at LendingTree. Cardholders should expect their current cards’ interest rates to rise in the next billing cycle or two, he said.

Although 15-year and 30-year mortgage rates are fixed, and tied to Treasury yields and the economy, anyone shopping for a new home has lost considerable purchasing power, partly because of inflation and the Fed’s policy moves.

The average rate for a 30-year, fixed-rate mortgage currently sits at 6.48%, according to Bankrate, down slightly from November’s high but still much higher than it was a year ago.

“While borrowers can save money relative to what they would have paid for a mortgage a few months ago, they’re still going to be shelling out much more than they would have had they bought a home at the start of last year,” said Jacob Channel, senior economic analyst at LendingTree.

“All in all, there’s no getting around just how tough today’s housing market is for many people to break into and navigate.”

Adjustable-rate mortgages, or ARMs, and home equity lines of credit, or HELOCs, are pegged to the prime rate. As the federal funds rate rises, the prime rate does, as well, and these rates follow suit. Most ARMs adjust once a year, but a HELOC adjusts right away. Already, the average rate for a HELOC is up to 7.99%, according to Bankrate.

Even though auto loans are fixed, payments are getting bigger because the price for all cars is rising along with the interest rates on new loans.

The average rate on a five-year new car loan is now 6.58%, according to Bankrate.

Keeping up with the higher cost has become a challenge, research shows, with more borrowers falling behind on their monthly loan payments.

Federal student loan rates are also fixed, so most borrowers aren’t immediately affected by rate hikes. The interest rate on federal student loans taken out for the 2022-23 academic year already rose to 4.99%, and any loans disbursed after July 1 will likely be even higher. Interest rates for the upcoming school year will be based on an auction of 10-Year Treasury notes later this month.

For now, anyone with existing federal education debt will benefit from rates at 0% until the payment pause ends, which the U.S. Department of Education expects to happen sometime this year.

Private student loans tend to have a variable rate tied to the Libor, prime or Treasury bill rates — and that means that, as the Fed raises rates, those borrowers will also pay more in interest. How much more, however, will vary with the benchmark.

While the Fed has no direct influence on deposit rates, the yields tend to be correlated to changes in the target federal funds rate. The savings account rates at some of the largest retail banks, which were near rock bottom during most of the Covid pandemic, are currently up to 0.39%, on average.

Thanks, in part, to lower overhead expenses, top-yielding online savings account rates are as high as 4.5%, according to Bankrate.

However, if this is the Fed’s last increase for a while, then deposit rate hikes are likely to slow, according to Ken Tumin, founder of DepositAccounts.com.

But “it’s not too late,” said Greg McBride, chief financial analyst at Bankrate.com. “We may not see much more in the way of improvement but there’s still a substantial advantage,” he said of switching to a high-yield savings account.

“There’s no advantage to staying where you are if you haven’t benefited from rising rates.”
