President Donald Trump revealed that the United States intervened in the foreign exchange market to support the yen at Japan's request, calling it a gesture of friendship and beneficial for the global economy. Speaking aboard Air Force One on Sunday, Trump said the yen had weakened and Japan needed help. After the intervention on Friday, the yen briefly rebounded to the lower end of 155 yen per US dollar in Tokyo trading. Japanese Finance Minister Satsuki Katayama confirmed the intervention, while economists view it as a sign of US concern over Japan's economic trajectory and its impact on US interest rates.
