the policy of Ministry of Finance to reduce the official discount rate are insufficient in explaining the actions taken by the Bank of Japan. Trying to deflate speculation and keep inflation in check, the Bank of Japan sharply raised inter-bank lending rates in late 1989. This sharp policy caused the bursting of the bubble, and the Japanese stock market crashed. Equity and asset prices fell, leaving overly-leveraged Japanese banks and insurance companies with books full of bad debt. As a result, bank credit growth stagnated, and as Professor Richard Werner warned at the time, the economy would not recover until bank credit for the real economy recovered (this took until 2013). He provides evidence that the central bank chose not to increase bank credit since their tightening of credit burst the bubble, because a prolonged recession would help implement structural reform. The financial institutions were bailed out through capital infusions from the government, loans and cheap credit from the central bank, and the ability to postpone the recognition of losses, ultimately turning them into zombie banks. Yalman Onaran of Bloomberg News writing in Salon stated that the zombie banks were one of the reasons for the following long stagnation. Additionally, Michael Schuman of Time magazine wrote that these banks kept injecting new funds into unprofitable "zombie firms" to keep them afloat, arguing that they were too big to fail. However, most of these companies were too debt-ridden to do much more than survive on bail-out funds. Schuman believed that Japan's economy did not begin to recover until this practice had ended. Eventually, many of these failing firms became unsustainable, and a wave of consolidation took place, resulting in four national banks in Japan. Many Japanese firms were burdened with heavy debts, and it became very difficult to obtain credit. Many borrowers turned to sarakin (loan sharks) for loans. As of 2012, the official interest rate was 0.1%; the interest rate has remained below 1% since 1994. Economic effects Despite mild economic recovery in the 2000s, conspicuous consumption of the 1980s has not returned to the same pre-crash levels. Japanese firms such as Toyota, Sony, Panasonic, Sharp, and Toshiba, which had dominated their respective industries from the 1960s to the 1990s, had to fend off strong competition from rival firms based in other East Asian countries, particularly South Korea, and China, since the 2000s.
