Definition, types How to be valued and effect on FIs Dramatic growth and related regulations Returns and Risks of OBS Activities The Role of OBS Activities in Reducing Risk
Off-Balance-Sheet Activities
In accounting terms – appear below the bottom line, frequently just as footnotes to financial statements
In economic terms – contingent assets and liabilities that affect the future, rather than the current shape of as FI’s balance sheet
Off-Balance-Sheet Activities
Off-Balance-Sheet Activities
Off-Balance-Sheet Asset - Contingent Gain
- When an event occurs, this item moves onto the
asset side of the balance sheet. Off-Balance-Sheet Liability
- Contingent Loss
- When an event occurs, this item moves onto the
liability side of the balance sheet.
Valuation of OBS Activities
Option features Contingent asset / liability value
(Delta Equivalent)= Notional value × Delta of an option
Delta = ————————————————————
ex. An FI has an OBS asset of call option on bonds with a notional
value of $100million and the delta is 0.25Contingent asset value = $25million
Change in the option’s price
Change in price on underlying security

*E = A + CA - L - CL
Incentives to Do OBS Activities Earn more fee income to offset declining
margins or spreads on traditional lending business
Avoid regulatory costs or taxes since reserve requirements and capital adequacy requirements were not levied on off-balance-sheet activities
Hedge on-balance-sheet interest rate, foreign exchange, and credit risks

Note that data after 1994 do not include spot FX in the total notional amount ofderivatives. Credit derivatives were reported for the first time in the first quarter of 1997. Currently, the CallReport does not differentiate credit derivatives by product and thus they have been added as a separatecategory.

Returns and Risks of OBS Activities
Loan commitments Standby letters of credit and letters of credit Futures, forward contracts, swaps, and
options When issue securities Loans sold
Loan Commitments
A certain maximum amount, at given interest rate terms, in a period of time
Up-front Fee Back-end Fee Example Maximum amount = $10million
BR = Interest on the loan = 12%m = Risk premium = 2% t = Expected takedown rate = 75%f1 = Up-front fee = 0.125% ( of $10million )f2 = Back-end fee = 0.25% ( of $2.5million )b = Compensating balance = 10%R = Reserve requirements = 10%
Loan Commitments
The promised return (1+k) of the commitment is :
1 + k = 1+ ————————————
1 + k = 1 + —————————————————————
1 + k = 1.1566 or k = 15.66%

Loan Commitments
Interest Rate Risk Takedown Risk
This exposes the FI to future liquidity risk or uncertainty.
Credit Risk Aggregate Funding Risk
In credit crunches, spot loans may decline but loan- commitment-takedown not. However, cost of funds rise above than normal level in this time.
Commercial Letters of Credit
A contingent payment guaranty for domestic and international trade
Letter of credit fee Default risk on letter of credit
U.S. FI
1(Orders $10 million of machinery)
3( machinery shipped)
($10 million letter of credit issued) 2
U.S. importer German exporter
Standby Letters of Credit
A contingent payment guaranty for CP issuing firm onto maturity
Standby Letter of credit fee Default risk on standby letter of credit The LC or SLC fees should exceed the
expected loss from default risk, after adjusting for reclaiming and any monitoring costs.
When Issued Securities
Commitment to buy and sell securities before issue
Sell the yet-to-be-issued securities in the secondary market at a small margin above the price expected to pay at the primary auction
Risk of mistake regarding the tenor of the auction
Nonschedule L Off-Balance-Sheet Risks Settlement Risk
An FI is exposed to a within-day or intraday credit risk that does not appear on its balance sheet.
Affiliate RiskThe failure of an affiliated firm or bank imposes affiliate risk on another bank in a holding company structure.
The Role of OBS Activities in Reducing Risk When used to hedge on-balance-sheet risks, OBS i
nstruments can actually reduce overall insolvency risk.
Regulatory costs of hedging have risen, and caused FIs to underhedge, thereby increasing, rather than decreasing, their insolvency risk.
Noninterest fee income from OBS activities can potentially compensate for risk exposure for some FIs.
Optimum is always the point.

Macrohedging : Hedging the entire duration gap of an FI
Interest Rate Risk- Macrohedging with Futures

Credit Risk Hedging with Forward FIs are afraid of the decline in credit quality of
a borrower Solution: They could buy a credit forward to
hedge against an increase in default risk on an loan after the loan rate is determined and the loan is issued
