The dollar will remain king – but only of a smaller hill

January 2026, Interview: "Few economists can claim a résumé as eclectic as Kenneth Rogoff’s. Before he was advising governments and lecturing at Harvard as the Thomas D. Cabot Professor of Public Policy and Professor of Economics, he was outthinking opponents as an internationally ranked chess player, even achieving the title of grandmaster. His career includes serving as Chief Economist at the International Monetary Fund (IMF), where he played a pivotal role in navigating economic challenges of the early 2000s. Rogoff has now turned his analytical mind to the future of the US dollar. In his latest book, Our Dollar, Your Problem, he explores how America’s currency shapes – and sometimes destabilises – the world economy in an era of shifting global power. Blending economic insight with a strategist’s instinct, Rogoff unpacks the risks and realities of a financial system still ruled by the greenback, but increasingly undermined by rivals such as the renminbi and stablecoins, as well as political polarisation in the US."
