Mark Sobel

Mark Sobel spent over three decades at the US Treasury Department, becoming Deputy Assistant Secretary for International Monetary and Financial Policy and the US representative to major international forums including the G7, G20, and IMF. He worked on international monetary system reform, exchange rate diplomacy, and financial crisis responses. After leaving Treasury, he became US chair at OMFIF (Official Monetary and Financial Institutions Forum), where he publishes research on dollar policy, SDR reform, and international monetary coordination. His Treasury career encompassed major events including the Asian financial crisis, the dot-com era capital flows, the 2008 global financial crisis, and multiple episodes of currency market volatility. He developed deep expertise in the US approach to exchange rate policy, including the criteria and process for designating countries as currency manipulators in the Treasury's semi-annual foreign exchange reports to Congress. At OMFIF, he has been a prominent voice on the dollar's role in the international monetary system, the geopolitical dimensions of dollar hegemony and potential reserve currency diversification, and the implications of central bank digital currencies for international monetary arrangements. His writing and commentary are widely read by policymakers, investors, and researchers focused on international finance.
