PRINCIPLES OF BANK MANAGEMENT
The bank’s balance sheet
Managing the bank’s balance sheet:
1. Liquidity management.
2. Asset management.
3. Liability management.
4. Capital adequacy management.
Off-balance-sheet activities.
The bank’s balance sheet
Four core / traditional principles of bank management:
Liquidity management.
Asset management.
Liability management (only to prominence since 1960s).
Capital adequacy management.
These four principles all concern management of the bank’s balance sheet.
This has two columns; Assets and Liabilities:
Liabilities – sources of the bank’s funds.
Assets – uses to which the bank puts these funds.
TOTAL TOTAL
Assets Liabilities
Example of a bank’s balance sheet:
Reserves consist of:‘Vault Cash’ (UK: ‘Cash in Till).Funds held by the bank in its account at the Central Bank
If a cheque for £100 is drawn upon Bank I and is paid by the recipient into Bank II, then Bank I owes Bank II £100.
This debt is paid through the clearing system at the Central Bank:
The CB withdraws £100 from the account of debtor bank (A) and pays it into the creditor bank (B).
There is thus a one-to-one relation between deposits and reserves.
Reserves Deposits
Assets Liabilities
Bank I
Reserves Deposits
Assets Liabilities
Bank II
‘T-accounts’: These are simplified balance sheets listing only the changes that occur in balance sheet items starting from an initial balance sheet position.
Reserves Deposits
Assets Liabilities
Bank II
Bank II has now gained £100 in reserves. Say it has a Required Reserve Ratio of 10%.It thus has an additional £ of Excess Reserves.
Required Reserves Deposits
Assets Liabilities
Bank II
Excess Reserves
It can use these ER to invest in interest bearing assets (reserves earn no interest).
Bank profit:
Revenue from assets, e.g.• interest from loans, securities, etc.
less
Costs incurred on liabilities, e.g.Costs of servicing a deposit account:
Recall: Bank II gained £90 of Excess Reserves as a result of A’s deposit.It now uses the addition to its ER to make a loan to B at 10%.
Required Reserves Deposits from A
Assets Liabilities
Bank II
Loan to B
It pays A 5% on his/her deposit.An additional cost of 3% is incurred in servicing this account.
Its profit is thus: Revenue on asset side: £9
less Costs incurred on liabilities side: £=
Return on Assets: Profit (i.e. revenue net of costs) as percentage of total assets.
When it first received A’s deposits the resulting return on its increase in assets was nil:
Reserves receive no interest → ROA = 0/100 = 0%.
Required Reserves Deposits
Assets Liabilities
Bank II
Excess Reserves
But once it had used the addition to its ER to make a loan to B, it made a profit of £ ( = Revenue £ m – Costs £ m).
→ ROA = / = %.
Bank Capital.
The difference between a bank’s assets and liabilities.
→ alternatively defined as ‘net worth’.
Included in the liabilities column of the balance sheet.

Principal 1 Liquidity management.
Sustain adequate liquidity to meet deposit outflow
Deposit outflow means equivalent loss of reserves
→ Liquidity management is equivalent to
Reserve adequacy management.
Replenishing reserves
Original / ‘traditional’ means:
Adjust the balance sheet:
Borrow from other banks or firms, or Central Bank (discount loans).
Sell securities.
Call in or sell off loans.
BUT: Rearranging balance sheet is costly:
Borrowings: Payment of interest.
Sell securities: Loss of interest.
Calling in loans: Loss of interest.
BUT ALSO / most costly of all:
Also damage to customer relationships.
Probable ‘fire sale’ conditions → poor price:
Loss of subjective / informational value.
ER thus traditionally a form of insurance / ‘cushion’ against these costs.
In fact largely superseded in recent decades:
Other forms of insurance -- hedging / derivatives, etc.

Note the very low ER of US banks since the early 1960s.Note also inverse relationship to interest rate.
Dwindles almost to zero when r is high.
A bank’s Assets are: reserves £20m, loans £80m, securities £10m.Its Liabilities are £100m deposits.Its RRR is 10%.It now faces a deposit withdrawal of £10m.

No action is needed to replenish reserves following this withdrawal:

Cost: Interest paid.
In case of borrowings from CB, this is the ‘Discount Rate’.
Note: The bank’s BS has here ‘expanded’.
Before borrowing, it had been only 100m

Cost (besides loss of interest):Transaction costs (brokerage, etc.).Can be very low in case of govt securities (Gilts, US TBs, etc.) ‘Secondary reserves’.

Cost: The costliest of all:• Damages customer relationships.• Selling loans on may be at unfavourable price:• Loss of informational element in their value.• Particularly if sold under ‘fire sale’ conditions.
Replenishing reserves (3) Call in loans. → Loans fall from 90m to 81m:
Principle 2: Asset management.
Assets vary in:
liquidity
riskiness
nature of their returne.g. fixed interest payments or
dividends.
Variation in liquidity → asset management is interconnected with liquidity management.
e.g. easily-traded securities like US Treasury Bonds, UK ‘Gilts’, etc., may serve as ‘secondary reserves’
A financial asset for one agent is by definition a liability for another.
The bank’s reserves are no exception:
They are a liability for the CB.
Reserves thus appear in the CB’s liabilities column!
(So does cash.)
Other kinds of assets provide direct utility of various kinds.
e.g. owner-occupied housing.
Note: An asset for one agent is a liability for another.Every category of economic agent has liabilities to, and assets with, banks: HH, FF, G; also other BB and CB.
Definition Liquidity Risk on principal

Inflation.
i.e. Government debt. High (‘secondary reserves’ for banks)
Same as government bonds, though default risk normally higher.
Shares in FF. Quite high (stock exchange)
Very high.
Very low High. Interest rate risk, etc.
Normally totally illiquid prior to retirement.

Liquidity Risk on principal Return

Inflation. Zero on cash, zero to very low on most deposits and other categories.

Asset management must address issues of risk:
Notably credit risk.
Also interest-rate and exchange-rate risk.
Credit risk management:
Central issue is asymmetric information.
i.e. Borrower is better informed on own risk profile than bank.
Traditional strategies for countering credit risk :
Screening borrowers before issuing loan.To counter ‘adverse selection’.
Monitoring borrowers’ behaviour after loan is issuedTo counter ‘moral hazard’.
Diversification or specialization.
Imposing restrictive conditions (‘covenants’) on borrowers’ use of the loan.
Requiring borrowers to supply collateral.
Credit rationing.
BUT: Now largely credit swaps and other innovations.
Principle 3: Liability management.
Traditional / original form of issue to non-equity-holders of liabilities was deposit creation for customers.
It is this aspect of bank management that has changed the most radically in recent decades.
Stylised pre-history of banking.
A gold dealer provides a service to customers:
•Stores their gold coins in a safe house.
•Issues deposit notes to them for the amount stored.
e.g. The owner takes in £100 in gold coins, shown as T-account:
Gold coins Deposit notes
Assets Liabilities
Safe house
These deposit notes become accepted in transactions as a substitute for payment in gold
i.e. Gold (‘commodity money’) becomes ‘customary money’ – a financial instrument (‘bank note’).
A safe house owner storing £100 in gold coins now makes loans to the value of £900.
Gold coins Deposit notes
Assets Liabilities
Safe house
Loans issued
i.e. The store house owner has now become an early ‘banker’, issuing credit.
