According to CoinWorld, the Japanese yen suddenly jumped against the US dollar on Thursday, as traders remained highly alert to the possibility that Japanese authorities may have intervened to support the yen. It is currently unclear what triggered this market volatility or whether Japanese authorities have intervened in the market. The magnitude of this fluctuation appears smaller than the movements following previous rounds of intervention. Hirofumi Suzuki, chief foreign exchange strategist at Sumitomo Mitsui Banking Corporation, said: "It is still unclear whether this is intervention. However, as reported, authorities may have shifted their intervention strategies and tactics, potentially no longer signaling intervention in advance, which could make it more difficult for the yen to weaken further."
