日本前高级外汇官员：外汇干预配合加息效果将更为持久

Core Viewpoint - The use of foreign exchange reserves for currency intervention can have an immediate impact on the market, but its effects will be more lasting if accompanied by a commitment to sustained interest rate hikes [1] Group 1: Currency Intervention and Interest Rates - Former senior foreign exchange official Takahiko Nakao emphasizes that actual monetary intervention can strongly influence the market, but a clear commitment from the Bank of Japan (BOJ) to continue raising interest rates would enhance the durability of this effect [1] - The BOJ raised interest rates to 0.75% in December last year, yet the actual borrowing costs remain deeply negative [1] - Nakao attributes the weakness of the yen to the BOJ's continued accommodative stance, noting that the slow pace of rate hikes has resulted in significantly negative real interest rates when adjusted for inflation, alongside an expanding US-Japan interest rate differential [1] Group 2: Inflation and Long-term Bond Yields - Nakao suggests that responding appropriately to inflation through interest rate hikes may help curb excessive rises in long-term Japanese bond yields [1] - He warns that if the BOJ delays rate hikes, the yen may weaken further, referencing the nomination of Walsh as the next Federal Reserve Chair, who may favor a strong and stable dollar as beneficial for the US [1]
