【Golden Finance Express】As the yen continues to slide against the dollar, Japanese authorities face a stark reality: unless the Federal Reserve eases its long-running policy path, the decline will be hard to stop. Global investors have realized how high borrowing costs in the United States boost the dollar and its impact on the rest of the world. The continued plunge in the yen is an extreme manifestation of the United States' financial dominance. This year, the Federal Reserve's high interest rates have reverberated in the foreign exchange market, with many major currencies weakening against the dollar due to interest rate gaps. Efforts by Tokyo officials to support the yen have so far been ineffective, and further intervention may be equally ineffective. Data released on Monday showed that asset managers have been heavily shorting the yen, with last week's data being the most pessimistic since 2006. The huge interest rate gap between Japan and the United States has been the main driver of the yen's decline this year.
