Japanese asset price bubble
economic bubble in Japan from 1986 to 1991 in which real estate and stock market prices were greatly inflated, collapsing in early 1992
The Japanese asset price bubble (バブル景気, baburu keiki; lit. 'bubble economy') was an economic bubble in Japan from 1986 to 1991 in which real estate and stock market prices were greatly inflated. In early 1992, this price bubble burst and the country's economy stagnated. The bubble was characterized by rapid acceleration of asset prices and overheated economic activity, as well as an uncontrolled money supply and credit expansion. More specifically, over-confidence and speculation regarding asset and stock prices were associated with financial policy deemed to exacerbate them. Through the creation of economic policies that cultivated the marketability of assets, eased the access to credit, and encouraged speculation, the Japanese government started a prolonged and exacerbated Japanese asset price bubble.
By August 1990, the Nikkei stock index had plummeted to half its peak by the time of the fifth monetary tightening by the Bank of Japan (BOJ). By late 1991, other asset prices began to fall. Even though asset prices had visibly collapsed by early 1992, the economy's decline continued for more than a decade. This decline resulted in a huge accumulation of non-performing asset loans (NPL), causing difficulties for many financial institutions. The bursting of the Japanese asset price bubble contributed to what many call the Lost Decade.
