Low inflation rates in Asia, especially in Japan, Taiwan, and China, have become a major concern for monetary policy. The reason for this is due to factors like rapid economic growth and setting inflation targets too low. When inflation is very low or negative, people tend to delay spending, which can slow down economic growth. This situation can be worsened by interest rates being at their lowest possible level. To address these challenges, policymakers need to carefully consider their inflation targets and how they manage demand in the economy.
