Federal debt held by the public was $11.90 trillion in the third quarter of 2013 (71% GDP) and is
projected to grow to $21.0 trillion by 2024 (78% of projected 2024 GDP, according to the
Congressional Budget Office (see below).
Year Gross Federal Debt Federal Debt Held by Public
2013 $16.7 Trillion $11.9 Trillion (71% GDP)
2024 (Projected debt and % projected GDP) $27.0 Trillion $21.0 Trillion (78% GDP)
Growth 62% 76%
Large levels of debt held by the public create the potential for crowding out and/or excessive
dependence on foreign investment. Interest expense is projected to grow substantially over the
next decade as well. When debt held by public (which is the measure that affects the credit
markets) hits about 90% most economists believe that GDP growth will be retarded, perhaps
holding back GDP growth by up to 1%, … but nobody knows for sure, and it depends on interest
rates and ability to attract foreign source money.
Teaching Tip:
One can illustrate the problem of high debt levels by appealing to corporate theory. Using debt
provides a boost to ROE when the money is invested and earns a sufficiently high return to grow
income. Otherwise the use of debt will eventually crowd out other spending. The question that
taxpayers/voters have to ask is whether the money invested will generate a sufficient return to
warrant borrowing such high levels. Certainly, as in all debt usage, increasing debt levels adds to
risk and potentially erodes the value of the dollar. The U.S. has been able to continue with such
high debt levels because the global reserve currency status of the dollar generates sustained
demand for the currency. At some point, and no one knows when, the world may no longer be
willing to hold as many dollars and at that point the U.S. will have a much more difficult time
financing its deficit.
Teaching Tip:
The credit rating agency, Standard & Poor’s, downgraded the U.S. from a AAA credit rating.
There was very little market impact from the downgrade, perhaps because Fitchs and Moody’s
did not downgrade the debt or more likely because the market did not consider the U.S. to be
significantly riskier. You may wish to ask students to consider whether United States’ Treasuries
are truly risk free in real and nominal terms. Could the U.S. have a sovereign debt crisis similar
to Europe?
a. Treasury Notes and Bonds
T-notes and bonds are default risk free. T-notes have an original issue maturity from 1 to 10
years inclusive, whereas T-bonds have original maturities more than 10 years. Both types pay
interest semi-annually. Price quotes are in 32nds as a percent of par. The minimum par or face
value has been $1,000, but the text is now quoting $100. The Treasury also issues inflation
indexed bonds where the principle is adjusted for inflation.
In 1985 the Treasury began its Separate Trading of Registered Interest and Principle Securities
(STRIP) program. A STRIP is a Treasury security where each individual coupon payment and
the principle payment at maturity can be separated and sold individually. STRIPs are registered
securities; a private dealer requests that the Treasury ‘strip’ the individual payments and keep a
record of them on the Treasury’s computer system. Each payment will be given its own CUSIP
