The Federal Reserve decided on Tuesday (Oct. 3) to leave interest rates unchanged, although it expressed concern about higher energy prices possibly fueling inflation.

Beginning late last year and early this year, the Fed raised rates on several occasions to prevent the economy from growing so fast that it would spark inflation.

On Tuesday, for the first time, the Fed said it was concerned workers might start to demand inflationary wage increases to offset higher energy costs.

However, the Fed believes the current interest rate environment, to this point, has slowed economic growth to a sustainable, non-inflationary, rate.
