US-Japan Intervention Sets Precedent for Currency Interventions

The U.S. Treasury Department has assisted Japan in propping up the yen, sparking questions about motivations and policy implications.

Last week's surprise announcement saw the yen surge from a 40-year low of 163 yen per dollar to 155 yen per dollar, but it has since surrendered half of its gains.

The Japanese authorities face the prospect that the surge in oil prices and a weak yen will boost import prices and add to inflation pressures.

Treasury Secretary Scott Bessent's motive is to lessen the need for Japanese authorities to sell Treasuries to fund their currency market intervention, with Japan holding $1.1 trillion in U.S. debt.
