What the Mark Carney era may offer is a little bit more predictability on monetary policy. Under Mervyn King the main guidance came from the Bank’s quarterly Inflation Report press conferences, MPC minutes, and speeches by committee members. Under the Bank’s new remit, set by the Chancellor in the March budget, it’s likely that Carney, like Bernanke, will seek to link interest rates and monetary policy directly to growth and jobs targets
There will be subtle changes but no one, as economists at HSBC have noted, is expecting ‘shock and awe’. The big question for Carney is which indicators to use as targets. The runners are unemployment (as in the US), real GDP, or the measure preferred by many economists: nominal GDP.
