BUENOS AIRES – The global financial crisis has raised fundamental questions regarding central banks’ mandates. Over the past few decades, most central banks have focused on price stability as their single and overriding objective. This focus supported the ascendancy of “inflation-targeting” as the favored monetary policy framework and, in turn, led to operational independence for central banks. The policy was a success: the discipline imposed by strict and rigorous concentration on a sole objective enabled policymakers to control – and then conquer – inflation.
But, as a consequence of this narrow approach, policymakers disregarded the formation of asset- and commodity-price bubbles, and overlooked the resulting banking-sector instability. This, by itself, calls for a review of the overall efficacy of inflation-targeting. Moreover, after the financial crisis erupted, central banks were increasingly compelled to depart from inflation targeting, and to implement myriad unconventional monetary policies in order to ameliorate the consequences of the crash and facilitate economic recovery.
