USD/JPY Volatility Linked to Joint Intervention and U.S. Treasury Market Impact
The recent USD/JPY market volatility has been attributed to a joint U.S.-Japan intervention, but behind the scenes, it's affecting the vast U.S. Treasury market.
On August 6, the exchange rate hovered around 157.7 after rapid volatility, with intraday swings far exceeding typical levels. This was not solely driven by changes in interest rate differentials.
The intervention involves providing U.S. dollar liquidity to Japan through repurchase agreements, which helps avoid destabilizing the U.S. Treasury market but blurs boundaries among foreign-exchange intervention, balance-sheet management, and monetary policy.
