Per Financial Times reporting cited by Bloomberg, the US intervened in currency markets to support the yen, which had fallen to a 40-year low, by selling euros rather than dollars. The ECB was told only after the trade was done. Japan has signalled it will act again if needed. For a Thai SME, this is background: it signals currency volatility among major currencies, so watch import costs in yen or euro-linked inputs and any pricing that depends on them. No action is needed this week.
