Yen Slides Toward Critical Threshold, Triggers Intervention Fears

The Japanese yen has weakened past the critical 160-per-dollar threshold, sparking fears of coordinated intervention by Tokyo and Washington to stabilize markets.

Currency traders in Tokyo and New York are watching the screens with bated breath as the yen slides relentlessly toward the psychologically vital 160-per-dollar mark.

The persistent weakness of the world's third-largest economy's currency has reignited fears of massive market intervention by the Bank of Japan and the US Federal Reserve, sending ripples through emerging markets from Nairobi to Lagos and threatening to upend global carry trade strategies.

The yen's depreciation is primarily driven by a widening monetary policy divergence between Japan and the United States. While the US Federal Reserve has maintained relatively high interest rates to combat sticky domestic inflation, the Bank of Japan has historically clung to ultra-loose monetary policies to stimulate economic growth.
