Goldman Sachs said US support for Japan’s yen intervention is unlikely to erode the dollar’s position as the world’s primary reserve currency. Japan is the largest foreign investor in the roughly $31 trillion US Treasury market. After last month’s coordinated US-Japan currency intervention, some market participants warned such measures—aimed at preventing sharp moves in the US bond market—could weaken confidence in dollar reserve assets. Goldman strategists, including Michael Cahill, said that argument rests on the assumption the US would try to block other countries from selling Treasuries in future, which they called "far‑fetched," and they do not expect the action to damage the dollar’s reserve status.
