How did the US Dollar become the dominant currency internationally? What keeps other currencies, fiat or crypto, from displacing the dollar's role? Does the aggressive use of sanctions by the US Government put the dollar's role at risk? Paul Blustein is with the Center for Strategic and International Studies, as well as an author and journalist. He has written several books including his latest work King Dollar: The Past and Future of the World's Dominant Currency and previous works, Off Balance: The Travails of Institutions That Govern the Global Financial System, And the Money Kept Rolling In (and Out) Wall Street, the IMF, and the Bankrupting of Argentina, and Laid Low: Inside the Crisis That Overwhelmed Europe and the IMF. Greg and Paul discuss the reasons behind the US dollar's dominance in global finance, its historical roots stemming from the Bretton Woods Agreement, and the challenges posed by international crises and economic policies. Paul also discusses the role and limitations of the IMF, the geopolitical implications of using the dollar as a financial weapon, and the potential impact of emerging currencies and digital threats. The episode concludes with insights into the phenomena of dollarization and how various economic strategies, including those of China and Russia, intersect with the enduring power of the US dollar. *unSILOed Podcast is produced by University FM.*
