A process which involves surplus units depositing funds with financial institutions who then lend to deficit units
Main functions of a Financial Intermediary
Brokerage function
Asset transformation function (Qualitative Asset Transformation function)
Brokerage function
Match transactors and provide transaction and other services - nature of claims not changed
Reduce transaction costs
Remove information costs
Asset transformation function (Qualitative Asset Transformation function)
Financial intermediaries hold long-term, high-risk, large-denomination claims issued by borrowers and finance this by issuing short-term, low-risk, small-denomination deposit claims to depositors
Makes deposits attractive to savers than the lending directly to corporations in terms of lower monitoring costs, lower liquidity costs and lower price risk
Maturity Transformation
Liquidity Transformation
Components of Asset Transformation
Asset diversification function
Asset evaluation function
Asset diversification function
With a small sum, depositors can spread his risk to many borrowers
Asset evaluation function
Borrowers have more information than the depositors (Asymmetries of information)
Difficult for depositor to evaluate the borrower directly
Banks takes on the evaluation role on behalf of the depositors
Distinguishing features of a Financial Intermediary
Main category of liabilities (deposits) are specified for a fixed sum which is not related to the performance of a portfolio
Deposits are typically short-term and of a much shorter term than their assets
A high proportion of their liabilities can be withdrawn on demand
Liabilities and assets are largely not transferable
Reasons why Financial Intermediation is preferred over Direct Financing by the individual saver
Transaction costs
Liquidity insurance
Information-sharing coalitions
Delegated monitoring
Components of transaction costs relating to lending
Search costs
Verification costs
Execution cost
Monitoring costs
Enforcement costs
When the transaction cost including the borrower, the saver and bank (Tb1+ Ts1 + C) is lower than the all in cost paid by the saver and borrower before introduction of the bank (Tb + Ts)
It makes sense for the bank to act as the Financial Intermediary
How the bank achieves lower transaction cost as compared to direct financing
Use of distribution channels to reduce search cost for customers
Banks helps lower monitoring cost
Standard forms reduce negotiation cost
Economies of scale
Economies of scope
Liquidity
Individuals are unsure of their future liquidity requirements in the face of unanticipated events, and hence they maintain a pool of liquidity
How a bank reduces the overall liquidity requirements of all the individuals as a pool
Assumption that since shocks are not perfectly correlated across individuals, not everyone needs money at the same time
Portfolio theory suggests that the total liquid reserves needed by a bank will be less than the aggregation of the reserves required by individual consumers acting independently
By holding a small pool of money, bank can allow individuals who need money early to withdraw first while those who do not need their money can withdraw later
Liquidity Insurance
The bank's assurance to the surplus unit that they can have access to their funds as and when they need it
Borrower is likely to have more information than the lender about the risks of the project for which they receive funds (Information Asymmetry)
Problems of Information asymmetry
Adverse Selection (Before loan is made) - Increases the probability that bad credit risks will get loans, lenders may decide not to give any loans, even to good credit risks
Moral Hazard (by Borrower after loan is made) - Borrowers are more likely to behave differently when using borrowed funds rather than when using their own funds
How banks help in bridging the savers and borrowers since there is information asymmetry
Bank is able to afford the cost of good quality information through economies of scale
Surplus units can benefit from good quality information if they place their funds with the bank for lending to deficit units
Why a lender needs to monitor a borrower
Information collection before and after a loan is granted, including screening of loan applications - to ensure collectability of loans
Examining the borrower's ongoing creditworthiness
Ensuring that the borrower adheres to the terms of the contract
Why a bank is able to perform the monitoring function better than an individual saver
Efficiency - Privileged information, Provide credibility, Possess economies of scale, Exposed to higher level of risk by banks – more incentive to get good information
Expertise - Have specialist, Developed reputational capital as monitors of credit risk, Regulators are monitoring the banks
Delegated monitoring
Not all savers have the time, inclination or expertise to monitor borrowers for default risk. FI provide a solution by pooling funds from suppliers (e.g. household savers) and investing in the financial claims of corporations. Therefore the surplus units appoint the FI as delegated monitors due to the FI's efficiency and expertise.
For delegated monitoring to be feasible, the cost of delegated monitoring (monitoring via intermediary) must be less than the minimum of: (a) costs without monitoring, and (b) total costs of direct monitoring by multiple lenders
Conditions under which the borrower would prefer direct financing
When the borrower has good credit risk, established reputation, good prospects for growth
Bank run
A bank run occurs when a large number of bank customers simultaneously withdraw their deposits because they believe the bank is, or might become, insolvent
What makes banks vulnerable to runs
Asset Transformation Function - Financing long-term assets (e.g. loans) through short-term deposits is the source of potential fragility of banks, because they are exposed to the possibility that a high number of depositors will decide to withdraw their funds for reasons other than their own liquidity needs
Liquidity transformation function - The deposits are liquid and thus can be withdrawn at any time while the assets of the bank are illiquid
How the features of a deposit contract contribute to a bank run
Non-time deposits are payable on demand
Claims to fixed amounts regardless of the performance of the bank's assets
Funds are given to depositors on a first-come, first-served basis (Sequential service constraint) - Customers are therefore subject to likely default on the last redemption claim serviced
Theory on bank runs
Banks offer highly liquid and low price-risk contracts to savers on the liability side, while holding relatively illiquid and higher price-risk assets
Under ordinary circumstances, savers' unpredictable needs for cash are unlikely to occur at the same time, so the bank expects only a small fraction of withdrawals in the short term
Sequential service constraint - The bank will be able to pay the first depositors who demand their money back, but if all others attempt to withdraw too, the bank will go bankrupt and the last depositors will be left with nothing
Self-fulfilling prophecies - Each depositor's incentive to withdraw her funds depends on what she expects other depositors to do
Nash Equilibrium - If enough depositors expect other depositors to withdraw their funds, then they all have an incentive to rush to be the first in line to withdraw their funds irrespective of the outcome to the bank
Main arguments for implementing bank regulations
Systemic (the whole financial system) Stability
Protection of payment system
Consumer Protection
Depositor Protection
Unregulated private actions create outcomes whereby social marginal costs are greater than private marginal costs
Regulated banking leads to lower cost
Problems deposit insurance gives rise to
Under full insurance, depositors lack incentives to monitor a bank's activities, because they will suffer no losses if the bank fails
Banks are tempted to take on excessive asset risk and to hold lower reserves
How capital mitigates excessive risks taken by banks
Capital provides a buffer intended to absorb losses while permitting the bank to continue operating, and thus preventing default
Capital provides confidence for depositors and other creditors
Measures of capital adequacy
Gearing ratio = Debt / Equity
Risk asset ratio = Capital / Risk Adjusted Assets
1988 Capital Adequacy Accord of the Basle Committee
Also known as Basle I, use the risk–assets ratio to determine the adequacy of a bank's capital
Ratios proposed under Basle I
Total risk-based capital ratio = Total capital (Tier I + Tier II) / Credit risk-adjusted assets = at least 8%
Tier I (core) capital ratio = Core capital (Tier I) / Credit risk-adjusted assets = 6% min
What is included in Tier I and Tier II under Basel I
Tier 1 capital includes common stockholders' equity, non-cumulative perpetual preferred stock and minority interest in equity accounts of consolidated subsidiaries
Tier II capital includes loan loss reserves (up to a specified maximum), perpetual preferred stock, hybrid debt/equity instruments, subordinated debt, and revaluation reserves
Main criticism of Basle I
Risk weights were rather unsophisticated and inadequately related to default risk

Main criticism of Basle I
Risk weights were rather unsophisticated and inadequately related to default risk
The most serious objection related to the uniform 100 per cent weighting applied to commercial loans
The capital requirement is additive across loans, with no reduction in capital requirements arising from greater diversification of a bank's loan portfolio
Differences in taxes and accounting rules could mean that measurement of capital varies widely across countries
