The U.S. has defaulted on its debt before

Since the day of Alexander Hamilton, the United States has never defaulted on the federal debt.

That’s what we budget-watchers always say. It’s a great talking point. One that helps bolster the argument that default should not be an option in Washington’s ongoing debt limit slowdown.

There’s just one teensy problem: it isn’t true. As Jason Zweig of the Wall Street Journal recently noted, the United States defaulted on some Treasury bills in 1979. And it paid a steep price for stiffing bondholders.

Terry Zivney and Richard Marcus describe the default in The Financial Review (sorry, I can’t find an ungated version):

Investors in T-bills maturing April 26, 1979 were told that the U.S. Treasury could not make its payments on maturing securities to individual investors. The Treasury was also late in redeeming T-bills which become due on May 3 and May 10, 1979. The Treasury blamed this delay on an unprecedented volume of participation by small investors, on failure of Congress to act in a timely fashion on the debt ceiling legislation in April, and on an unanticipated failure of word processing equipment used to prepare check schedules.

The United States thus defaulted because Treasury’s back office was on the fritz....
