How central banks should prepare for the next recession

IT HAS BEEN a decade since America’s latest recession, and it has taken that long for the Federal Reserve to ask itself whether it is ready for the next one. On June 4th officials and scholars will gather in Chicago to debate how monetary policy should work in a world of low interest rates. The benchmark rate is 2.25-2.5%, which gives the Fed little room to cut before hitting zero—and less than half as much as it has needed in past downturns. As if to remind policymakers that rock-bottom rates are here to stay, the ten-year Treasury yield fell below 2.3% this week. Other central banks, many of which preside over still lower rates and weaker economies, are looking to the Fed for inspiration.
