Japan's core consumer price index (CPI), excluding one-off factors and measured by the Bank of Japan's (BoJ) new gauge, increased by 2.7% in May, slightly easing from a 2.8% rise in April but remaining above the BoJ’s 2% inflation target [1]. The core-core CPI, which also excludes special factors, rose 2.1% in May compared to a 2.2% increase in April [1].
The market responded modestly to the data, with the USD/JPY currency pair rising 0.07% on the day to 161.67 at the time of reporting [1]. This suggests a limited but positive reaction in the foreign exchange market, possibly reflecting expectations around the BoJ’s monetary policy stance.
The BoJ has historically maintained an ultra-loose monetary policy to stimulate inflation and economic growth, but began unwinding this stance in March 2024 by lifting interest rates, citing persistent inflation above its target and rising salaries as key factors [1]. The central bank’s policy shift has contributed to a partial reversal of the Yen’s previous depreciation against major currencies [1].
The continued inflation above target may influence future BoJ policy decisions, as the central bank aims to ensure price stability while monitoring the effects of its recent policy adjustments [1].
CONCLUSION
Japan’s core inflation remains above the BoJ’s 2% target, reinforcing the central bank’s recent shift away from ultra-loose monetary policy. The modest market reaction indicates that investors are closely watching for further policy signals as inflation persists.
