Money, Banking & FinanceLecture 1 The Nature of Financial Intermediation K Matthews

Aims • Explain the theory and purpose of financial intermediation. • Describe the structure of financial markets • Show that financial intermediation is welfare superior to direct transformation of current consumption to future consumption. • Describe the process of financial intermediation and the markets that enable its efficient functioning.

Financial Intermediation • The mechanism whereby surplus funds from ultimate savers are matched to deficits incurred by ultimate borrowers • The process by which ultimate savers are matched to ultimate borrowers. • Saving = Income – Consumption • Typically decisions to save are made independently of decisions to invest

Chanelling of Funds • In a simple economy we have firms and households • Households are the savers and firms are the investors. • The mechanism by which households save is by demanding securities from firms • The mechanism by which firms invest is by supplying securities to households • These securities are claims to the assets of the firm

Direct Finance • Lending and borrowing can occur as a result of direct transacting. • But there are costs associated with direct finance • Search costs – searching for potential transactors • Verification costs – costs in evaluating investment proposals • Monitoring costs – costs of monitoring the actions of borrowing • Enforcement costs – costs of enforcing contracts

Efficient Direct Finance • Some of these costs can be reduced through the organisation of a market. • Direct financing requires the existence of an efficient securities market. • However not all costs are minimised through a securities market. • An additional issue is that the maturity period of finance for the firm is long term. • The maturity period of the household is mostly short term. • The maturity mismatch of households and firms provide the incentive for the development of intermediated finance.

Who are the savers and borrowers? • Savers or lenders are households, firms, governments and foreigners • Investors or borrowers are households, firms, governments and foreigners. • Savers can hold corporate securities (shares), government securities (bonds), currency, bank deposits, foreign currency assets • Borrowers can sell shares, sell bonds, issue currency, take bank loans, issue foreign currency liabilities

A Flow of Funds Analysis • S = Saving • I = private investment • G = government spending • T = taxes • X = exports • M = imports • Y = C + I + G + X – M • Y = C + S + T • 0 = (I – S) + (G – T) + (X – M)

Financial Assets • H = high powered money = Currency + bank reserves • D = Stock of Bank deposits • L = Stock of Bank loans • Q = Stock of Private securities • B = Stock of government bonds • F = Stock of foreign financial assets • A superscript ‘d’ represents demand and a superscript ‘s’ represents supply.

Stocks and Flows • A stock is measured at a point in time • Stock of assets, money, bonds, physical capital measured at 31 December 2007 • Flows are measured over a period of time • Examples of flows are GDP, Savings, Investment measured quarterly, or annually

Implications of Financial Intermediation • Assumptions • Two-period analysis • Perfect capital market – (a) can borrow or lend at the same rate of interest, (b) perfect information, (c) costless access to capital market. • Investment opportunities are infinitely divisible • PIF – physical investment opportunities frontier • FIL – financial investment opportunities line

Structure of Financial Markets • Firm (or individual) obtains funds in the debt market or the equity market • A debt instrument (bond or mortgage) pays a fixed income stream over a specified period. • The maturity of the debt instrument is short term if less than a year, long term if more than 10 years and intermediate term if in between, • Equities (common stock) are claims to shares in the profits and assets of a business. • Equities pay periodic sums called dividends. • The disadvantage of equity is that the holder is a residual claimant

Primary and Secondary Markets • Primary market is the market for new issues of securities, or initial public offerings (IPOs) • Secondary market is where existing securities are traded (NYSE, NASDAQ, LSE, etc) • Some IPOs are well known and advertised and attract a lot of attention but many are of unknown enterprises and are underwritten by a known investment bank. • Brokers are agents of investors who match buyers and sellers of securities. Dealers link buyers and sellers by buying and selling securities at stated prices. A Market Maker buys/sells at the quoted bid-ask spread with the aim of making a profit on the spread.

Money and Capital Markets • Markets are sometimes distinguished on the basis of maturity of the securities traded. • The Money Market is a financial market where short term debt instruments are traded (less than a year) – Commercial paper, Bills etc • The Capital Market is where long term debt (longer than one year such as bonds) and equities are traded. • The money market is usually more liquid and more traded and so is used by financial institutions to earn income on surplus funds.

International Financial Markets • Foreign bonds are denominated in the currency of the market in which it is sold. • Eurobond is bond denominated in in a currency other than the currency of the market in which it is sold. • Eurocurrencies are foreign currencies deposited in banks outside the home country. • Eurodollars are dollars deposited in banks outside the USA

Summary • We have looked at the process and theory of financial intermediation. • Efficient direct finance is conducted through the mechanism of an efficient capital market • Indirect finance is through the process of a financial intermediary. • Financial intermediation is welfare superior to non-market direct financing.
