Yen Intervention Falls Short as Japan's Economic Policy Comes Under Scrutiny

The Japanese government has sought assistance from the US to prop up the yen, which has been experiencing a historic depreciation. The two governments have coordinated an intervention in the currency market, with the US buying yen and selling dollars for the first time in 28 years.

This move is unusual outside of major disasters or global economic crises, as it can distort financial markets. However, the Japanese government was unable to correct the yen's weakness through its own efforts, prompting a request for help from Washington.

The US Treasury Secretary Scott Bessent led the coordinated intervention, citing concerns that turmoil in Japanese markets would push up US long-term interest rates. Japan has incurred a significant debt to the US as a result of this move, and may be pressured into concessions such as completing investment commitments under the Japan-U.S. tariff agreement.

The root cause of the yen's weakness lies in market distrust of Japan's economic policies, which prioritize fiscal expansion over consolidation and independent monetary policy. To address this issue, the Japanese government must review its economic policy and take steps to restore market confidence.
