Adam Posen, president of the Peterson Institute for International Economics, discusses US Treasury Secretary Scott Bessent's push to support the Japanese yen, calling the threat to weaken the dollar "credible" but "very shortsighted." Speaking with Bloomberg's Stephen Carroll and Caroline Hepker, Posen examines the thinking behind the Trump administration's currency policy, rising bond yields and $100 dollar oil prices, as well as mounting fiscal and political risks across the US and Europe.
