Part IV The Management of Financial Institutions Chapter Twenty Two RISK MANAGEMENT IN FINANCIAL INSTITUTIONS
Managing Credit Risk • Solving Asymmetric Information Problems • 1. Screening • 2. Monitoring and Enforcement of Restrictive Covenants • 3. Specialize / Diversify in Lending • 4. Establish Long-Term Customer Relationships • 5. Loan Commitment Arrangements • 6. Collateral and Compensating Balances • 7. Credit Rationing promote長期關係 and information flow
Managing Interest-Rate Risk 15x0.1 • First National Bank • Assets Liabilities • --------------------------------------------------------------------------------------------------------------------- • Reserves and cash items $ 5 m | Checkable deposits $ 15 m • | • Securities | Money market deposit accounts $ 5 m • less than 1 year $ 5 m | • 1 to 2 year $ 5 m | Savings deposits $ 15 m • greater than 2 year $ 10 m | • | CDs: Variable-rate $10 m • Residential mortgages | less than 1 year $ 15 m • Variable rate $ 10 m | 1 to 2 year $ 5 m • Fixed rate (30 year) $ 10 m | greater than 2 year $ 5 m • | • Commercial Loans | Fed funds $ 5 m • less than 1 year $ 15 m | • 1 to 2 year $ 10 m | Borrowings: less than 1 year $10 m • greater than 2 year $ 25 m | 1 to 2 year $ 5 m • | greater than 2 year $ 5 m • Physical capital $ 5 m | • | Bank capital $ 5 m 15×0.2 10×0.2
Income Gap Analysis • RSA, which has interest rate that will be reset (repriced) within one year • Rate-Sensitive Assets = $5m + $ 10m + $15m + 20% x $10m • RSA = $32 m • Rate-Sensitive Liabs = $5m + $25m + $5m+ $10m + 10% x $15m • + 20%x$15m • RSL = $49.5 m • If i 5% in one year • increase Asset Income = + 5% x $32.0m = + $ 1.6m • increase Liability Costs = + 5% x $49.5m = + $ 2.5m • increase Income = $ 1.6m - $ 2.5 = - $0.9m • If RSL > RSA, iNIM, Income • GAP = RSA - RSL • = $32.0m - $49.5m = -$17.5m • ΔIncome = GAP x Δi • = - $17.5m x 5% = -$0.9m 改進:maturity bucket approach
Duration of First National Bank's Assets and Liabilities 100 95
Duration Gap Analysis • %ΔP - DUR x Δi/(1+i) • i 5%, from 10% to 15% • ΔAsset Value = %ΔP x Assets • = -2.7 x .05/(1+.10) x $100m • = -$12.3m • ΔLiability Value = %ΔP x Liabilities • = -1.03 x .05/(1+.10) x $95m • = -$4.5m • ΔNW = -$12.3m - (-$4.5m) = -$7.8m • Alternatively, • DURgap = DURA - [L/A x DURL] • = 2.7 - [(95/100) x 1.03] • = 1.72 • %ΔNW = - DURgap x Δi/(1+i) • = - 1.72 x .05/(1+.10) • = -.078 = -7.8% • ΔNW = -.078 x $100m • = -$7.8m
Example of Finance Company • Friendly Finance Company • Assets Liabilities • ------------------------------------------------------------------------------------------------- • Cash and Deposits $ 3 m | Commercial Paper $ 40 m • | • Securities | Bank Loans • less than 1 year $ 5 m | less than 1 year $ 3 m • 1 to 2 year $ 1 m | 1 to 2 year $ 2 m • greater than 2 year $ 1 m | greater than 2 year $ 5 m • | • Consumer Loans | Long-Term Bonds • less than 1 year $ 50 m | and other long-term • 1 to 2 year $ 20 m | debt $ 40 m • greater than 2 year $ 15 m | • | Capital $ 10 m • Physical capital $ 5 m | 90 100
Gap and Duration Analysis Finance company RSA>RSL.∴income gap>0 DURgap< 0∴ DURA<(L/A)DURL ∴利率上升較有利income, MW • If i 5% • Gap Analysis • GAP = RSA - RSL = $55 m - $43 m = $12 million • ΔIncome = GAP x Δi = $12 m x 5% = $0.6 million • Duration Gap Analysis • DURgap = DURA - [L/A x DURL ] • = 1.16 - [90/100 x 2.77] = -1.33 years • %ΔNW = - DURgap X Δi /(1+i) • = -(-1.33) x .05/(1+.10) • = .061 = 6.1% Commercial bank RSA<RSL.∴income gap<0 DURgap> 0∴ DURA>(L/A)DURL ∴利率上升較不利income, MW ∴ΔNW=0.061×100m=6.1m
Managing Interest-Rate Risk • Problems with GAP Analysis • 1. Assumes slope of yield curve unchanged and flat • 2. Manager estimates % of fixed rate assets and liabilities that are rate sensitive Income gap假設利率改變時,yield curve斜率不變 Duration gap更進一步假設yield curve斜率=0
Managing Interest-Rate Risk DURGAP=DURA-(L/A)DURL =2.7-(95/100)×1.03=1.72>0 • Strategies for Managing Interest-Rate Risk • In example above, shorten duration of bank assets or lengthen duration of bank liabilities • To completely immunize net worth from interest-rate risk, set DURgap = 0 1. Reduce DURa = 0.98 DURgap = 0.98 - [(95/100) x 1.03] = 0 2. Raise DURl = 2.80 DURgap = 2.7 - [(95/100) x 2.80] = 0
