Fed hikes interest rates for seventh time this year

The Federal Reserve has raised interest rates for the seventh time this year, while signaling that it is moving more cautiously as the U.S. economy slows.

The Fed's rate-setting committee hiked its benchmark rate by 0.5 percentage point on Wednesday, lifting its target rate into a range between 4.25% and 4.5% — the highest level in 15 years. The federal funds rate affects the cost of borrowing for consumers and businesses throughout the economy. 

The half-percentage-point increase marks a step-down from a string of bigger interest rate hikes this summer, when the Fed made four consecutive 0.75% jumps in an effort to curb the most ferocious bout of inflation in four decades.
