The smartest money moves to make now that interest rates are going higher

The Federal Reserve's quarter-point interest-rate increase raises the cost of borrowing across a wide range of consumer and business credit. Because the federal funds rate feeds into the prime rate, variable-rate debt — credit cards, home-equity lines of credit, and many private student and auto loans — typically reprices within one or two billing cycles. Fixed-rate mortgages are largely unaffected, though new mortgage rates tend to track longer-term Treasury yields rather than the Fed's move alone.

For savers, the transmission is slower and less uniform. Yields on money-market funds and short-term Treasury bills have historically responded quickly to policy changes, while bank deposit rates — especially at large institutions — often adjust with a lag. That gap is why the phrase "the Fed hikes, your savings don't" circulates after tightening cycles.

What to watch: the pace and endpoint of further increases, the spread between market yields and what your bank pays, and whether higher servicing costs start to show up in consumer credit data. Those signals matter more than any single meeting's decision.
