HKS professors Meghan O’Sullivan and Jeffrey Frankel say the draconian sanctions on Putin’s regime—which came together faster than almost anyone predicted—will have far-reaching and lasting effects well beyond Russia’s borders. In a nuclear-armed world where direct superpower conflict can have apocalyptic consequences, the proxy battlefield has become economics and finance. Instead of firing missiles, combatants lob sanctions to inflict pain and achieve strategic goals. Rather than cutting off supply routes, opponents cut off access to capital reserves and international financial systems. And during the first weeks of Russia’s war on Ukraine, developments on both the physical and economic battlefields have been swift and unpredictable. But now with an international sanctions regime against Vladimir Putin’s Russia taking shape with a depth and a breadth that took many analysts by surprise, it’s possible to widen the lens on the war in Ukraine to explore not only how it may shape the conflict, but also its potential to disrupt the world order and even create a new one.  O’Sullivan is Director of the Geopolitics of Energy Program at HKS and a former Deputy National Security Advisor under President George W. Bush. Frankel is an international economist and a former member of the Council of Economic Advisors under President Bill Clinton. They join host Ralph Ranalli to discuss sanctions and what the world economic order could look like in a post-Ukraine War world. Jeffrey A. Frankel is the James W. Harpel Professor of Capital Formation and Growth at Harvard Kennedy School. He is also a Research Associate at the National Bureau of Economic Research.

Before coming to Harvard in 1999, he was Professor of Economics at the University of California at Berkeley.
