Yen Surges as US and Japan Intervene in Currency Markets

Asian stock markets reacted to recent currency interventions by the US and Japan on Monday. The two countries confirmed last week's joint efforts to prop up the value of the Japanese yen against the dollar.

The yen surged, falling from nearly 164 yen per dollar to around 155.20 yen after the intervention was confirmed. This move has boosted profits for Japanese companies with overseas operations and attracted foreign tourists.

However, a weaker yen also increases Japan's costs for importing oil and other essential goods.

The US Treasury bought yen through the Federal Reserve Bank of New York to help boost its value, while the Japanese side spent over $50 billion on intervention. Analysts see this as a strong signal that Washington is willing to work with Tokyo to defend the yen.
