1 Chapter 24 Central banking and the monetary system David Begg, Stanley Fischer and Rudiger Dornbusch, Economics, 6th Edition, McGraw-Hill, 2000 Power Point presentation by Peter Smith

2 24.1 The central bank n acts as banker to the commercial banks in a country n and is responsible for setting interest rates. n In the UK, the Bank of England fulfils these roles. n Two key tasks: – to issue coins and bank-notes – to act as banker to the banking system and the government.

3 24.2 The Bank and the money supply n Three ways in which the central bank MAY influence money supply: – Reserve requirements n central bank sets a minimum ratio of cash reserves to deposits that commercial banks must meet – Discount rate n the interest rate that the central bank charges when the commercial banks want to borrow n setting this at a penalty rate may encourage commercial banks to hold more excess reserves – Open market operations n actions to alter the monetary base by buying or selling financial securities in the open market

4 24.3 The repo market n A gilt repo is a sale and repurchase agreement – e.g. a bank sells you a gilt with a simultaneous agreement to buy it back at a specified price at a specified future date. – this uses the outstanding stock of long-term assets (gilts) as backing for new short-term loans n Used by the Bank of England in carrying out open market operations

5 24.4 Other functions of the Bank of England n Lender of last resort – the Bank stands ready to lend to banks and other financial institutions when financial panic threatens n Banker to the government – the Bank ensures that the government can meet its payments when running a budget deficit n Setting monetary policy to control inflation – more of this later

6 24.5 The demand for money n The opportunity cost of holding money is the interest given up by holding money rather than bonds. n People will only hold money if there is a benefit to offset that opportunity cost.

7 24.6 Motives for holding money n Transactions – payments and receipts are not perfectly synchronized: n so money is held to finance known transactions n depends upon income and payment arrangements n Precautionary – because of uncertainty: n people hold money to meet unforeseen contingencies n depends upon the (nominal) interest rate

8 24.7 Motives for holding money (2) n Asset – people dislike risk – so may hold money as a low-risk component of a mixed portfolio n depends upon opportunity cost (the nominal interest rate) n Speculative – people may hold money rather than bonds – if bond prices are expected to fall – i.e. the interest rate is expected to rise n depends upon the rate of interest and on expectations about bond prices

9 24.8 The demand for money: summary n The demand for money is a demand for real money balances n It depends upon: – real income – nominal interest rate (the opportunity cost of holding money) – the price level (currently assumed fixed) – expectations about future interest rates

10 24.9 Money market equilibrium Real money holdings Interest rate LL Other things being equal, the demand for real money balances will be lower when the opportunity cost (the rate of interest) is relatively high. The position of this schedule depends upon real income and the price level. When money supply is L 0, money market equilibrium occurs when the rate of interest is at r 0. L0L0 r0r0

11 24.10 Reaching money market equilibrium Real money holdings Interest rate LL L0L0 r0r0 If the rate of interest is set below the market equilibrium – say at r 1 r1r1 there is excess demand for money (the distance AB) AB This implies an excess supply of bonds – which reduces the price of bonds and thus raises the rate of interest until equilibrium is reached.

12 24.11 Monetary control Real money holdings Interest rate LL L0L0 r0r0 Given the money demand schedule: The central bank can... EITHER set the interest rate at r 0 and allow money supply to adjust to L 0 OR set money supply at L 0 and allow the market rate of interest adjust to r 0 BUT cannot set both money supply and interest rate independently.

13 24.12 Monetary control – some provisos n Monetary control cannot be precise unless the authorities know the shape and position of money demand n Controlling money supply is especially problematic – and the Bank of England has preferred to work via interest rates n The situation is further complicated by the relationship between the interest rate and the exchange rate

14 24.13 Targets and instruments of monetary policy n Monetary instrument: – the variable over which the central bank exercises day to day control – e.g. interest rate n Intermediate target – the key indicator used as an input to frequent decisions about when to set interest rates n The financial revolution has reduced the reliability of money supply as an indicator – and central banks increasingly use inflation forecasts as the intermediate target
