Bessent Warns of Yen Volatility's Impact on US Interest Rates

Treasury Secretary Scott Bessent defended his decision to intervene in the yen market last month, stating that extreme volatility could have far-reaching consequences for US interest rates. In a letter dated August 27th, Bessent explained that Japan is a major holder of US Treasuries, and disorderly markets in the Japanese currency could lead to forced unwinds, destabilizing global markets and increasing borrowing costs for American families and businesses.

Bessent's response was directed at Democratic Senator Elizabeth Warren, who had criticized the government's intervention. Bessent offered a sarcastic reply, suggesting that Warren might benefit from a tutorial on foreign exchange basics. The letter has been made public, with details of how much the US deployed in support of the yen remaining undisclosed.
