In this episode of the Sound of Economics, Paola Subacchi, Professor of international economics and chair of the advisory board of the Global Policy Institute at Queen Mary University of London, and Bruegel senior scholars Alicia García-Herrero and Michael Leigh join Giuseppe Porcaro for an age old discussion but with a twist. 

They try to understand the geopolitical role of money, in other words, currencies and capital flows. While unconstrained capital flows cause afflictions of the global economy, the current debate on currencies is in fact driven by politics rather than economics, as Alicia argued in an opinion piece recently: Politics, not economics, demands a strengthened international role for the euro. What would the next US Treasury Secretary, Janet Yellen do on the dollar?
