Worldwide stockmarket crash that began 19 Oct 1987, prompted by the announcement of worse-than-expected US trade figures and the response by US Secretary of the Treasury, James Baker, who indicated that the sliding dollar needed to decline further. This caused a world panic as fears of the likely impact of a US recession were voiced by the major industrialized countries. Between 19 and 23 Oct, the New York Stock Exchange fell by 33%, the London Stock Exchange Financial Times 100 Index by 25%, the European index by 17%, and Tokyo by 12%. The expected world recession did not occur; by the end of 1988 it was clear that the main effect had been a steadying in stock market activity and only a slight slowdown in world economic growth.
