ニクソン・ショック
The 1973–1974 stock market crash caused a bear market between January 1973 and December 1974. Affecting all the major stock markets in the world, particularly the United Kingdom, it was one of the worst stock market downturns since the Great Depression, the other being the financial crisis of 2007–2008. The crash came after the collapse of the Bretton Woods system over the previous two years, with the associated 'Nixon Shock' and United States dollar devaluation under the Smithsonian Agreement. It was compounded by the outbreak of the 1973 oil crisis in October of that year. It was a major event of the 1970s recession.
