Fed Rate Increase Raises Borrowing Costs and Savings Returns
The Federal Reserve raised its benchmark interest rate by 0.25 percentage points on September 16, bringing the federal funds target range to 3.75% to 4.0%. The increase, the first since July 2023, followed renewed consumer-price growth in August amid the war with Iran and came despite President Donald Trump’s calls for lower rates.
The Federal Open Market Committee, chaired by Kevin Warsh, said tighter monetary policy was needed to address inflation. The federal funds rate governs overnight lending among banks but also influences the prime rate, consumer credit costs and deposit returns. The prime rate typically sits three percentage points above the Fed’s benchmark.
Borrowers are likely to experience higher costs across several categories. Credit-card annual percentage rates, which are usually variable, are expected to rise within a few billing cycles. WalletHub estimated that the quarter-point increase could add about $2 billion in credit-card interest charges over 12 months.
New mortgage rates may also move higher, although fixed mortgage rates track Treasury yields and broader bond markets more closely than Fed policy. Adjustable-rate mortgages and home-equity lines of credit are more directly connected to the prime rate. A quarter-point mortgage increase could add approximately $65 to the monthly payment on an average new mortgage, according to TransUnion.
Rates on new automobile loans may rise modestly, adding to already elevated vehicle prices and financing costs. Existing federal student loans will generally remain unaffected because their rates are fixed, while borrowers with variable-rate private loans may pay more.
Savers may benefit. Banks often raise yields on high-yield savings accounts, certificates of deposit and money-market accounts after Fed increases. Economists noted that wealthier and older households may be better positioned because they often carry less variable-rate debt and hold more interest-earning savings. This creates uneven effects across borrowers, homeowners, students, and depositors alike.
