Between 1980 and 1982 the U.S. economy experienced a deep recession, the primary cause of which was the disinflationary monetary policy adopted by the Federal Reserve. The recession coincided with U.S. President Ronald Reagan's steep cuts in domestic spending. [Another] cause of the early 1980s recession was the Iranian Revolution of 1979, which sparked a second large round of oil price increases.
