The Japanese yen experienced its worst week since May, continuing a downward trend and nearing the psychologically important ¥165-per-dollar mark. On Thursday, the yen hit a fresh 40-year low of ¥163.99 against the US dollar, signaling significant currency devaluation. This decline underscores ongoing economic pressures and policy divergence between Japan and the United States. Analysts are closely watching the ¥165 level, as breaching it could further exacerbate the situation. The weakening yen impacts import costs for Japan and potentially influences the Bank of Japan's monetary policy. The current trend reflects a sustained period of dollar strength and persistent concerns about Japan's economic growth. This ongoing depreciation raises questions about potential intervention from Japanese authorities to stabilize the currency.
