Bank of Japan Raises Interest Rates to 1.25 Percent

The Bank of Japan raised its policy interest rate to 1.25 percent, the highest level in 31 years, in an effort to stabilize the yen and combat domestic inflation. Despite the hike, the yen remains significantly depreciated against the U.S. dollar, trading between 150 and 160 yen per dollar. This deviates sharply from the purchasing-power-parity equilibrium of approximately 93 yen reported by the OECD.

The currency weakness is driven by a wide interest-rate differential between Japan and the United States, where short-term rates remain near 4 percent. This gap encourages speculators to engage in the carry trade, which further pressures the yen. While the weak currency provides an advantage to exporters, it increases costs for importers and fuels inflation within Japan.

Former prime ministerial adviser Koichi Hamada argues that current rate levels are insufficient and that the central bank must pursue more aggressive monetary tightening to stabilize the economy. Meanwhile, Japanese Finance Minister Satsuki Katayama continues to coordinate with U.S. Treasury Secretary Scott Bessent on fiscal and monetary matters to address the economic imbalance.
