The Bottom Line
The Federal Reserve’s interest rate decisions ripple through every aspect of your finances. When rates are high, prioritize paying off variable-rate debt and take advantage of higher savings rates. When rates are low, consider locking in low mortgage rates and investing more aggressively. You can’t control Fed policy, but understanding it helps you make better financial decisions with the tools you have.
