The Federal Reserve said Wednesday it will maintain the benchmark interest rate at its current range of 4.25% to 4.5%

The Federal Reserve is expected to leave interest rates unchanged Wednesday, but also should provide important economic data and a forecast that could impact financial markets.

Later today, the Federal Reserve is expected to extend a pause on interest rate cuts for a fourth consecutive time this year. While mortgage rates could see some volatility, many economists expect them to stay relatively flat until the economic picture changes.
