Japan's Yen Intervention Fails to Gain Traction Amid Skepticism

The Japanese government and Bank of Japan have intervened in the foreign exchange market to defend the yen by injecting massive funds totaling approximately 55 trillion won. This intervention is estimated to have been implemented after the yen/dollar exchange rate plummeted to 157.80 yen on July 30 in the New York foreign exchange market.

According to market experts, the U.S. government also participated in this intervention. U.S. Treasury Secretary Scott Bessent was confirmed to be carrying a memo on 'purchasing yen valued at 5-10 billion dollars,' and exceptional simultaneous intervention by both Japan and the U.S. through banking notifications via the Federal Reserve Bank of New York has become concrete.

However, a pessimistic view dominates regarding whether the massive intervention will lead to a rebound in yen value. Masafumi Yamamoto, chief foreign exchange strategist at Mizuho Securities, strongly questioned the sustainability of this intervention's effects, forecasting that 'the yen appreciation effect from this intervention will not continue due to the Takaichi Sanae administration's expansionary fiscal policy and the Bank of Japan's accommodative monetary stance.'

The Japanese government has previously intervened in the foreign exchange market by injecting 11.7 trillion yen (approximately 107 trillion won) into the foreign exchange market three months ago, yet the yen weakness trend actually accelerated and persisted.
