The Federal Reserve raised interest rates on Wednesday (September 16), its first in over three years. This move is likely to increase borrowing costs while providing a modest boost to savers. Fed Chairman Kevin Warsh and the FOMC announced the widely anticipated 25-basis-point rate hike and hinted at one more. The stock market reaction likely dominated headlines, with Goldman Sachs partners leaning towards an optimistic scenario, predicting the S&P 500 will rise above 8,000 points within a year. The federal funds rate affects not only the stock market but also savings rates and, to a lesser extent, mortgage rates.

Impact on checking and savings accounts: Deposit returns rise slowly.

A series of Fed rate hikes may slowly improve deposit yields, but deposit accounts are primarily for convenience rather than substantial returns, yielding meager returns so far in 2026. The national average interest rate for checking accounts has barely changed this year, remaining at 0.07%. Rate hikes could slightly increase yields. Savings account rates are only slightly better, hovering around 0.38%, but savings accounts are for near-term funds. High-yield savings accounts are more effective in terms of interest payments, with rates mostly in the 3% range, occasionally reaching 4%. This is the category where interest rate comparisons and subsequent Fed rate hikes truly take effect. Money market accounts, for holdings of $10,000 or more and wanting funds on the sidelines but easily accessible, have always been convenient but low-yielding, averaging only 0.63% nationally. High-yield money market accounts are a better option; rates may still be close to 4%, but mostly in the mid-3% range.

Impact on mortgage rates: Approaching or exceeding 7%

Mortgage rates are often the largest borrowing expense for consumers. Federal Reserve rate hikes typically don't directly affect mortgage rates—the bond market tends to price in rate increases before monetary policy actions are taken. Mortgage rates hit a three-year low in late February and early March, but the subsequent Middle East conflict caused rates to rise instead of fall further. Mortgage rates have recently approached or exceeded 7% (depending on the source of the rate report), consistent with the rise in 10-year Treasury yields. Analysts at the Mortgage Bankers Association and Fannie Mae predict that mortgage rates will remain above 6.5% until 2027.

Impact on personal loans and student loans: An increase in personal loans indirectly affects student loans.

Personal loan rates have risen slightly to an average of 11.86%, while advertised rates are generally in the 7% to 8% range. The Federal Reserve influences consumer loan rates by setting the federal funds rate, which in turn affects interbank overnight lending costs, typically passed on to borrowers through higher or lower rates. Regarding student loans, the Fed does not directly set rates, but the federal funds rate influences the 10-year Treasury yield (which determines the federal lending rate) and the prime lending rate (which determines private loan rates). Congress sets the federal student loan rate based on the 10-year Treasury yield, adding a fixed spread annually. However, the 10-year Treasury yield moves with investor demand, not the Fed's rate. When investors anticipate high inflation or strong growth, they demand higher yields, potentially pushing up federal student loan rates. That said, if the Fed successfully raises rates to cool inflation, Treasury yields may fall, and federal student loan rates may be lower the following year. Private student loans are provided by banks, credit unions, and online lenders, many of which base their rates on the prime lending rate, which moves with the Fed's rate decisions.

Impact on credit cards: Interest rates have risen from 16% to over 22%.

Credit card interest affects everyone—except those who pay off their balance each month. Interest rates have climbed from around 16% in 2021 to an average of over 22% today. A leading U.S. research analyst predicts that as floating-rate credit products reflect the Federal Reserve's rate hikes, consumers will see "higher minimum" borrowing costs. She stated that consumers holding an average credit card balance of $6,610 in the second quarter of 2026 with an annual interest rate of 22% could see their minimum monthly payment increase by $1.38 as higher rates are passed on. While the immediate impact on minimum payments may be relatively small, higher borrowing costs accumulate over time, especially for consumers with larger balances or those who only make minimum payments. She added that reducing revolving debt will limit the impact of rising interest rates. Some media outlets suggest that the best way to get a lower credit card interest rate immediately is to ask. If you make regular payments and your credit score has improved, now is a good time to call your credit card provider to request a lower interest rate.

Impact on investment: Don't fight the Fed, but the economic backdrop remains relatively favorable.

A prominent macro research and strategy director at a leading institution stated that there's an old Wall Street adage: "Don't fight the Fed." The underlying idea is that Fed rate hike cycles are often accompanied by significant volatility. He pointed out that history shows the S&P 500 has seen an average maximum drop of over 10% within 12 months of the start of a higher-interest-rate cycle. However, he added that overall, the economic backdrop remains relatively favorable for Fed rate hikes, so even in a cycle with more than one rate hike, the economy may be able to weather the storm. Stock prices tend to react to Fed rate actions, but this is only one of many factors influencing the investment environment and stock prices. AI investments and oil-driven inflation appear to be the most significant drivers in the current stock market. To manage investments in the current environment, monitor broader economic and corporate profit trends, as well as interest rates. For a more conservative approach, fill your portfolio with high-quality stocks that have been validated through all economic cycles and patiently wait for long-term growth.
