The Federal Reserve and the U.S. Department of Treasury provide the broadest range of interest rate data.  The Federal Reserve provides data on the interest rates that are set by the government.  Those rates include the Bank Prime Loan Rate and U.S. Treasury Securities rates.

The Department of Treasury provides a number of different interest rates statistics.  The Treasury data included in this section focuses on corporate bond rates.  Those rates give a broader indication of interest rate trends than data limited to government rates.
