Price stability is one of the areas in which public institutions should be involved.6  The principle of the Bank's monetary policy is stipulated by the Bank of Japan Act. Article 2 prescribes that "[c]urrency and monetary control by the Bank of Japan shall be aimed at achieving price stability, thereby contributing to the sound development of the national economy."
The ultimate objective is not price stability itself but the resultant sound development of the national economy, generally accompanied by improvements in employment and household income.
