Kevin Warsh has spent his first three months as chair of the Federal Reserve pretty tight-lipped about his views on the economy, a stark contrast to how central bank policymakers have traditionally communicated with market participants. On this episode, host Stephanie Flanders speaks with Bloomberg Opinion columnist Bill Dudley, a former president of the Federal Reserve Bank of New York, and Robin Brooks, senior fellow at the Brookings Institution and chief FX strategist at Goldman Sachs, about whether Warsh’s approach is a welcome change or another threat to the Fed's credibility.
