Many economists argue that altering exchange rates is a form of monetary policy, given that interest rates and exchange rates are closely related.
The Bank of England’s Monetary Policy Committee (MPC) has responsibility for monetary policy in the UK. The MPC has nine members, four of whom are appointed by the Chancellor. The MPC has one goal – to hit its inflation target of 2%.
The inflation target is symmetrical because a rate of inflation below the target is considered as damaging as a rate of inflation above the target.
Changing the official base rate, which alters the cost of borrowing across the economy, is the most visible tool used by the MPC. The MPC's team of experts meet each month to discuss current and future monetary policy options, and set a rate which they believe will steer the economy towards achieving the target inflation rate.
The rate set by the MPC is the repo rate, which is the rate that the Bank of England will charge in the moneymarkets for short-term loans to other banks or financial institutions. Other rates of interest in the economy, such as mortgage and credit card rates, will adjust in line with changes to the official rate.
Interest rates are set so that the inflation target can be met in the future. It takes up to two years for a rate change to affect inflation, so the Bank of England must try to predict the state of the economy two years in advance.
The interest rate transmission mechanism
Interest rates transmit their way to aggregate demand in the following ways:
Household demand is affected because changes in interest rates affect savings, which indirectly affect spending.
For households or firms with existing debt, such as a mortgage, a change in rates affects repayments, and hence individuals have more (or less) cash after servicing their debts. Changes in rates affect the cash-flow of firms and households.
In the case of new debt to fund spending, borrowing is also encouraged (or discouraged) following interest rate changes.
Interest rates also affect consumer and business confidence, which in turn affects spending.
Asset values are also affected by interest rates. A fall in rates will tend to increase the profitability of firms and they may pay higher dividends to shareholders. This can trigger an increase in household spending. Similarly, a rate fall makes savings less attractive and property more attractive, increasing the value of property and household wealth.
Finally, interest rates may affect the exchange rate, which can also influence export demand. For example, a rise in interest rates may raise the exchange rate, pushing up export prices and reducing overseas demand. Changes in the exchange rate also affect the price of imports, which also affect the inflation rate.
In recent years. interest rates have been adjusted to reflect changing inflationary pressure, and general macro-economic conditions.
Rates were relatively high at 6% to restrict demand
In order to stimulate demand, between 2000 and 2003 rates were pushed down to what was then their lowest level for 25 years.
Rates were pushed up into a neutral zone at around 5% and edged towards the restrictive zone by the middle of 2007.
Rates were pushed down to a record low of 0.5% to stimulate household spending in the wake of the
financial crisis and recession.

If we assume the economy has an output gap, then a reduction in interest rates by the Bank of England will increase aggregate demand because saving is discouraged, new borrowing and spending is encouraged, and confidence and investment will increase. The effect of the increase in aggregate demand on real output and the price level depends upon the elasticity of aggregate supply.
Assuming the economy is at or very near to full employment, a reduction in interest rates may over-stimulate aggregate demand beyond the capacity of the economy to respond in the short run.
In this case, the effect is mainly on the price level rather than output and jobs.
Quantitative easing is a method of introducing new liquidity into the economy when interest rates are very low and approaching zero.
Evidence shows that, in normal conditions, interest rates have a direct and powerful effect on household spending, which suggests that UK consumers are highly interest rate elastic.
The Bank of England’s Monetary Policy Committee is independent from government and can make decisions free from political interference.
Interest rates can be adjusted on a monthly basis, which contrasts with discretionary fiscal policy which cannot be adjusted at such regular intervals.
While the full effects of interest changes may not be experienced for up to a year, there is often an immediate effect on confidence. The time-lag on output is estimated to be around one year, and on the price level, around two years.
There are still time lags to see the full effects, and there are some negative effects.
There is also the problem of the dual economy - are high rates set for the booming service sector, or low rates for the depressed manufacturing and export sector?
The money supply is difficult to control in practice, so controlling interest rates is preferable.
Interest rates may fall to very low levels during a deep recession, and
while the demand for credit may rise, the supply may become
trapped in the system, known as the
