Yen Intervention Sparks Carry Trade Fears and Crypto Volatility

The US Treasury and Japanese authorities have coordinated a massive yen-buying intervention for the first time in 15 years, with President Donald Trump describing it as a 'signal of friendship' between the two nations.

The intervention was substantial, totaling approximately ¥8.45 trillion ($53 billion), with the yen dropping from near 164 to the 156-157 range against the dollar after the operation.

This coordinated currency intervention is rare, and it's a reversal of previous events in 2011 when both countries intervened to prevent a deflationary spiral in Japan due to a strong yen.

The yen's decline has been driven by interest rate differentials between the US and Japan, with Japan keeping rates relatively low compared to the US.
