As a general point I wouldn't quote Greenspan on just about anything after the GFC > One of the arguments against inflation targeting, whether implicit or explicit, is that it invites asset bubbles--financial markets know that so long as the CPI[1] doesn't budge, they can go wild. But that's a somewhat different debate. Basel III introduced a 'discretionary counter-cyclical buffer' on capital requirements to enable central banks to better manage asset bubbles, while still focusing on price stability with the cash rate. > I think the basic argument against explicit targeting is that it hinders the Feds flexibility. With implicit targeting there's a degree of uncertainty and so markets arguably respond better to abrupt or unexpected changes; whereas with explicit targeting the Fed has to be more careful and gentle because markets will more heavily leverage against that fixed number. Central banks strive to keep inflation at the target band on average, over the long term. It doesn't stop them from taking quick and decisive action in a crisis. A cursory study of the bank's actions (under Bernanke) at the outset of the GFC will affirm this. https://en.wikipedia.org/wiki/Basel_III#Capital_requirements https://en.wikipedia.org/wiki/Basel_III#Capital_requirements
