BOJ Rate Hike Falls Flat as Fed's Shadow Keeps Yen Weak

The Bank of Japan's (BOJ) recent rate hike has failed to strengthen the yen, as expected. The USD/JPY exchange rate nearly reached 158 despite the 25 basis point increase in interest rates by the BOJ. This unexpected outcome is attributed to the simultaneous Fed rate hike, which keeps the US-Japan rate gap from narrowing and leaves yen borrowing profitable.

With rate hikes alone unable to bolster the yen, market analysts speculate that intervention through selling US Treasuries may be the next step for the BOJ. This would aim to reduce the yen's attractiveness for borrowing, thereby strengthening its value.
