Japan and the United States have undertaken a coordinated yen-buying intervention, marking the first such action in 28 years, as the yen's value plummeted to historic lows, nearing 164 to the dollar in late July, a level not seen since 1986.
This intervention, traditionally reserved for times of crisis, is now seen as an effort to curb excessive yen depreciation and mitigate potential disruptions in global financial markets. U.S. Treasury Secretary Scott Bessent noted in an interview that a key objective was to contain currency risk in Asia, as many regional currencies, like the Korean won, are influenced by the yen's weakness.
However, experts suggest that the intervention alone is insufficient to reverse the yen's fundamental decline and will at best provide a temporary reprieve. The core issues lie within Japan's domestic policies. Prime Minister Sanae Takaichi's government has maintained an expansionary fiscal stance, raising concerns about Japan's fiscal health. Additionally, the Bank of Japan faces pressure to demonstrate progress on interest rate hikes, with its September policy meeting being a critical focus for markets.
Persistent demand for dollars from Japanese companies, exacerbated by high global energy prices, also contributes to the yen's weakness. Speculators betting on further depreciation are likely to increase their influence amidst currency market volatility. Despite the intervention, the yen has since weakened again to 158 to the dollar. Toyota Motor, Japan's largest company, has revised its fiscal year 2027 exchange rate assumption to 160 yen per dollar, signaling expectations of continued yen weakness.
