Fed's silence may impact investors

The Federal Reserve, which controls interest rates in the U.S., hasn't said much about whether they'll change the current rate, which is between 3.50% and 3.75%.

This silence might make investors nervous.

Right now, jobs are doing okay, the economy is healthy, and prices aren't going up as fast as they were, even though oil prices are higher.

Even though prices have been going up more than the Fed's target of 2% a year for the past five years, these good signs might mean the Fed will keep rates the same.

But investors might still worry about what the Fed will do next.
