LONDON -Signs of de-dollarisation are unfolding in the global economy, strategists at the biggest U.S. bank JPMorgan said on Monday, although the currency should maintain its long-held dominance for the foreseeable future.

The strains of steep U.S. interest rate rises and sanctions that have frozen Russia out of the global banking system have seen a fresh push by the “BRICS” nations, Brazil, Russia, India, China, and South Africa, to challenge the dollar’s hegemony.

JPMorgan strategists Meera Chandan and Octavia Popescu said that while overall dollar usage is within its historical range and the greenback remains at the top of the pack, a closer look shows a more bifurcated picture.

Their assessment on the dollar is the most high profile by any large U.S. bank so far, although heavyweight money managers such as Goldman Sachs Asset Management have aired similar views.
