History

Historical Context

In the late 1980s Japan’s asset-price bubble (1986-1991) drove the Nikkei to a record 38,915 points in December 1989. Tightening monetary policy in 1989-1990 caused the index to plunge to 21,902 by December 1990, a 43% loss and sparked the “Lost Decade.” Regulators such as the Financial Services Agency now cite that episode as they consider curbing the renewed margin-buying surge at Kioxia Holdings.
