Off-Balance-Sheet Activities 陳秀蘭 楊雅智 翁明祥
Off-Balance-Sheet Activities Outlines • Definition, types • How to be valued and effect on FIs • Returns and Risks of OBS Activities • Loan commitments • Commercial letters of credit / Standby letters of credit • When issued securities • Futures and forwards Interest rate risk Foreign exchange risk Credit risk Catastrophe risk • Options, caps, floors, and collars • Swaps • Loans sold
Off-Balance-Sheet Activities • 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 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.
Change in the option’s price Change in price on underlying security 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 0.25 Contingent asset value = $25million

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
Regulations • 1983 Quarterly Call Report (Schedule L) List notional size and variety of OBS activities. • 1993 BIS Framework Impose capital requirements on OBS activities and explicitly recognize FI’s solvency risk exposure from pursuing OBS activities. • 1994 DSSSA Derivatives Safety and Soundness Supervision Act • 1994 GAO’s report
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% compared to the cost of capital f1 + f2(1-t) + (BR+m)t t – [bt(1-R)] 0.00125+0.0025(0.25)+(0.12+0.02)0.75 0.75-[(0.1)(0.75)(0.9)]
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
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 Risk The 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 instruments 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.
Futures and Forwards • Interest rate risk • Foreign exchange risk • Credit risk • Catastrophe risk
Interest Rate Risk Hedging with Forward • Change in bond values = Capital loss on bonds = Initial value of bond position = Change in forecast yield D = Duration of the bonds 1+R= 1plus the current yield
Interest Rate Risk Hedging with Forward • Suppose an FI holds a 20-year, $1million face value bond • As interest rates rise, the FI makes a capital loss on these bonds =$970000 D= 9 years = 0.02(from 8% to 10% over the next three months) 1+R = 1.08
Interest Rate Risk Hedging with Forward • Capital loss: Hedging: selling $1 million face value of 20-year bonds forward delivery in three months’ time
Interest Rate Risk Hedging with Futures • Microhedging versus Macrohedging • Microhedging : Using a futures (forward)contract to hedge a specific asset or liability • Macrohedging : Hedging the entire duration gap of an FI
Interest Rate Risk- Macrohedging with Futures • FI’s net worth exposure to interest rate changes =change in an FI’s net worth = duration of its asset portfolio =5 years = duration of its liability portfolio =3 years k = ratio of on FI’s liability to assets =0.9 A = size of an FI’s asset portfolio=$100million = shock to interest rates = (from 10% to 11%) • Loss on balance sheet: = -$2.091million
Interest Rate Risk- Macrohedging with Futures • Gain off balance sheet on selling futures = change in dollar value of futures contract = duration of the bond to be delivered against the futures contracts = the number of contract bought or sold = the price of each contract = expected shock to interest rates 1+RF= 1 plus the current level of interest rates
Interest Rate Risk- Macrohedging with Futures • How many futures ( )do we sell to fully hedge the interest rate risk • Assume the interest changes of the cash asset position match those of futures position =5years, =3years, k=0.9, A=$100m, =9.5years, =$970000 = = = 249.59contracts to be sold
Foreign Exchange Risk Hedging with Forward • Example:All assets and liabilities are 1 year Assets Liabilities U.S loans $100m U.S CDs $200m U.K loans$100m Risk : The pound will depreciate against the dollar Hedge: Selling both the pound loan principal and interest forward
Foreign Exchange Risk Hedging with Futures • Assuming perfect correlation between spot and futures prices Loan principal=£100m interest = £15m = spot exchange rate($/£)=$1.4713 per £1 = futures price($/£)=$1.4640 per £1 = $1.4213 per £1 = $1.4140 per £1 = -5cents = -5cents
Foreign Exchange Risk Hedging with Futures • The size of each British pound futures contract is £62500 = £115000000/£62500 = 1840 contracts to be sold Loss on British pound loan £115m*($1.4713/£-$1.4213/£) = $5.75m Gain on futures contracts (1840* £62500)* ($1.4640/£-$1.4140/£)= $5.75m
Foreign Exchange Risk Hedging with Futures • Assuming imperfect correlation between spot and futures prices = $1.4213 per £1 = -5cents = $1.4140 per £1 = -3cents let h be the ratio of to
Foreign Exchange Risk Hedging with Futures • The number of futures contracts to be sold changes = £115m*1.66/£62500 =3054.4 contracts Loss on British pound loan £115m*($1.4713/£-$1.4213/£) = $5.75m Gain on British pound futures position (3054.4*£62500)* ($1.4640/£-$1.4340/£)=$5.75m
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
Credit Risk Hedging with Forward • :the actual credit spread on the bond in maturity : the credit spread originally agreed to • MD : modified duration on the benchmark BBB bond • A : the principal amount of the forward agreement
Catastrophe Risk Hedging with Futures • Who need to transfer the catastrophe risk Property-casualty insurers are allowed to hedge the extreme losses Example: Payoff= loss ratio*nominal value of futures 0.8*$25000=$20000 Insurer Investor 1.5*$25000=$37500
