US Treasury Warns Against Excessive Yen Volatility, Pushes BOJ for Rate Hikes

The U.S. Treasury Department has expressed concern over Japan's weak yen in its semiannual foreign exchange policy report, stating that 'excessive volatility is undesirable.' The report released on July 23rd noted that despite a narrowing interest rate differential between the U.S. and Japan, the yen's depreciation continues.

The Treasury Department emphasized the importance of monetary policy normalization by the Bank of Japan (8301.T) in achieving exchange rate stability. A senior official stated that 'monetary policy normalization helps stabilize inflation expectations and curb excessive exchange rate volatility,' implying a need for additional rate hikes.

Market participants are now focused on how this warning will influence the BOJ's policy decisions, particularly with regards to potential rate hikes. The report also highlighted the importance of close consultations between the U.S. Treasury and Japan's Ministry of Finance on macroeconomic and exchange rate issues.
