The Bank of Japan’s independence was explicitly stipulated when the new Bank of Japan Act took effect in 1998, establishing a framework to ensure its autonomy from the government’s fiscal pressure. The move provided a legal foundation for the role of a central bank focused on price stability.
The Bank of Japan is described as the “guardian of price stability,” with the importance of its independence explained against its historical background. In light of the wartime underwriting of government bonds and postwar inflation, independence from the government has been regarded as essential to ensuring appropriate policy decisions from a long-term perspective.
The new Bank of Japan Act, which took effect in 1998, stipulated that autonomy in currency and monetary affairs should be respected, giving the Bank’s independence a legal basis. This is explained as making policy decisions less susceptible to being driven by short-term economic conditions.
The institutional framework supporting the Bank of Japan’s independence was developed alongside reforms of the Ministry of Finance, which were undertaken as part of broader government reforms. The stated aim was to maintain the Bank’s function as a “guardian” focused on long-term price stability.
The article summarizes the historical establishment of the Bank’s independence and its current legal standing, and makes no particular mention of future developments.
