Tax Foundation: Federal Debt Doesn't Raise Long Term Interest Rates

January 14, 2002

There is no evidence to support the frequently asserted link between federal debt and long-term interest rates, according to a memo by Tax Foundation chief economist John Barry being circulated by the Senate Finance Committee.

Barry charted the 10-year Treasury Constant Maturity Rate and publicly held federal debt as a percentage of gross domestic product (GDP) from 1953 through 2001.

  • Overall, he found, there appears to be a negative correlation between 10-year interest rates and publicly held federal debt as a percentage of GDP -- meaning that interest rates actually fell when federal debt rose, and interest rates rose as federal debt fell.
  • Over the last five years, Barry found no apparent correlation between publicly held debt and long-term interest rates.
  • In fact, between 1998 and 2000, a period of substantial budget surpluses and publicly held debt reduction, long-term interest rates rose from 5.3 percent to 6.0 percent.

The relationships held when real (inflation-adjusted) interest rates are considered.
