The conclusion is straightforward: the ability to navigate through the crisis, using either fiscal or monetary measures effectively and at modest overall cost, depends in both of these cases on the credibility of the authorities’ commitment to long-term monetary stability.

This is crucial even for a country as indispensable to the global economy as the US. For the UK, it is close to a matter of economic life and death.
