Recently, from Japan's unilateral rescue of the Japanese yen exchange rate to America's rare entry into it, what signals did the joint actions of the two sides send? Can the two sides join forces to reverse the long-term depreciation of the yen? Wan Zhe, a professor of economics at Beijing Normal University, pointed out that the rare joint intervention of the US and Japan in the yen exchange rate is a sign of risk escalation, indicating that the depreciation of the yen has escalated into a global financial risk. However, such foreign exchange intervention is only short-term management; there is no way to reverse long-term exchange rate trends determined by economic fundamentals and capital flows.
