JPMorgan Chase CEO Jamie Dimon says the U.S. dollar could lose its reserve-currency status if the United States no longer maintains its economic and military advantages. He frames reserve-currency dominance as tied to broader national power and confidence in the stability of the U.S. system.

Both outlets note that the dollar is currently the world’s dominant reserve currency, holding a large share of global foreign-exchange reserves—about 57% is cited in the Business Insider account. The Yahoo News item emphasizes Dimon’s warning about potential decline in the dollar’s role, while Business Insider provides the supporting context of the dollar’s current share. Neither source presents alternative forecasts or countervailing analysis in the provided text; the emphasis is on Dimon’s assessment and the dollar’s existing scale.
