The Japanese yen's rapid depreciation, which saw the U.S. dollar reach a 40-year high of 162.83 yen last week, may prompt coordinated intervention from major central banks. Michael Nizard of Edmond de Rothschild Asset Management stated that the yen's weakness doesn't reflect Japan's economic fundamentals, creating a misalignment that could spur action.

Nizard forecasts that without intervention, the dollar could reach 170 yen within three months, a level that would significantly boost Japanese industry competitiveness. He believes the U.S. administration would oppose such a scenario, increasing the likelihood of intervention.

The Bank of Japan, the U.S. Federal Reserve, and the European Central Bank are predicted to act in concert during the latter half of the year. Such coordinated efforts are seen as essential, as unilateral actions by any single central bank are unlikely to yield lasting results for the yen.
