Nikkei 225 surges 2% as USD/JPY nears 158 level

The Japanese stock market saw a significant boost, with the Nikkei 225 rising approximately 2% to the 66,800–66,900 yen range, driven by a resurgence in AI and semiconductor stocks following positive U.S. market performance.

In the foreign exchange market, the USD/JPY pair has fluctuated near the 158 level. Despite recent coordinated interventions by Japan and the United States, market fundamentals continue to favor dollar buying over yen selling. Discussion regarding these interventions highlights the use of the FIMA Repo Facility, a mechanism that allows Japan to use U.S. Treasuries as collateral to obtain dollars to purchase yen, thereby mitigating the need to sell Treasuries directly and avoid impacting bond prices.

Investors are currently monitoring upcoming U.S. Consumer Price Index (CPI) data and the Bank of Japan's monetary policy signals. While there is speculation regarding potential rate hikes in September, market volatility is expected to increase during the upcoming Obon holiday period due to lower trading volumes.
