Goldman analysts said the signal for intervention appears stronger than in 2022 or 2024 if U.S. participation is possible, though they cautioned that direct operations often have only temporary impact when broader pressures are justified; ahead of a Federal Reserve meeting and a possible Trump announcement on the next Fed chair, investors trimmed dollar positions as worries over another U.S. government shutdown weighed.
