Monetary Policy and Financial Stability

Monetary Policy in the UK has never been as expansionary as it is today. Just over 15months ago the level of Bank Rate was reduced to what is – to all intents anpurposes – its floor. As Chart 1 rather starkly shows, this is the lowest level to which Bank Rate has fallen since the Bank of England was established at the end of the seventeenth century. Bank Rate has not been changed for 16 consecutive meetings of the MPC. That is not so unusual. In fact, as the Chart reveals, between 1720 and 1820 Bank Rate did not move from 5%. Had a Monetary Policy Committee then met each month, as it does now, it would have decided at 1200 consecutive meetings not to change the level of interest rates. So it is far from unusual for the interest rate set by the Bank to remain constant for over a year. And for much of the period since rates fell to the floor, policy has been actively changed – asset purchases have built up to now stand at around £200 billion.

So it is the level to which interest rates have fallen that is unprecedented. I believe it has been right to loosen aggressively the stance of monetary policy because of the scale of the deflationary and recessionary forces unleashed by the remarkably rapid downturn that followed the crisis in the banking sector. This crisis intensified dramatically in the autumn of 2008 when the banking system came close to total collapse. That would have been an outcome comparable in its impact to the failure of the system for electricity supply. Many now argue that monetary policy should be set in a different way so as to reduce the chances of this sort of banking crisis. That is one of the issues I want to discuss today. The argument that the aims of monetary policy need to be broadened beyond a focus on inflation is one that deserves to be taken seriously because the damage done by extreme financial instability is great. If there were no tools better suited to help preserve financial stability than varying interest rates then the case for broadening the goals of monetary policy would be strong. But I believe there are tools better suited to make the financial system more robust and I want to consider one of them – capital requirements – and how they might in future interact with monetary policy. More immediately, problems and fragilities in the banking sector remain and pose risks that the recovery in demand and activity we have seen across Europe – including in the UK – falters. But in the UK we have also seen CPI inflation rise to a level that is significantly above the inflation target. In recent months CPI inflation has begun to fall, but remains well above the 2% target level and that makes setting monetary policy difficult. We continue to face the problem of balancing risks: risks that inflation of 1.0pp-1.5pp above target lasts long enough to become ingrained in expectations and affect behaviour so that it is hard to bring down, versus risks that the recovery in output becomes weaker and then disappears, leaving inflation pressures lower than is consistent with the target further ahead.
