The Monetary Stimulus

There was no change to UK base interest rates this week with the Monetary Policy Committee holding rates at 5.0% for May. Across the Channel, the hyperactive (!) European Central Bank also kept policy rates constant for what now seems like an eternity! Thank heavens the UK remains outside the Euro Zone! Whilst policy rates are at 5% for the moment, this does not mean that monetary policy is not acting as a stimulus to one or more of the components of aggregate demand (C+I+G+X-M).

The overall stance of monetary policy includes the effects of base rate movements and also changes in the external value of sterling against a basket of other currencies. So whilst interest rates have edged lower in recent months we should also take into account the major depreciation of sterling against the Euro Zone with whome we do more than half of our trade. A falling pound acts as an important stimulus to the export sector of the economy, even though the boost is muted somewhat by a slowdown in economic growth in our export markets. Will the lower pound be a white knight for the faltering UK economy?

Cheaper sterling to the rescue?

For some time now I have been arguing that the media should be paying more attention to the exchange rate when considering the propsects for the UK economy over the coming months. A cheaper currency acts as a boost to exports and aggregate demand and can be a very useful stabiliser in an economy weakening from the fall-out from the credit crunch. There are naturally risks from a sharp downward movement in the exchange rate, not least the impact on the prices of imported products and possible flow-through effects on cost and price inflation. But taken as a whole, a lower exchange rate is what the UK economy needs at the moment - and we are getting it! Charles Bean, Chief Economist of the Bank of England made clear reference to this in an important speech in London today - it is available to download here from the Bank of England website. I have picked out one paragraph in particular which focuses on the exchange rate and compares the impact of cuts in interest rates with currency depreciations.
