Asset-Liability Management

1. CHAPTER SIXAsset-Liability Management: Determining and Measuring Interest Rates and Controlling a Bank’s Interest-Sensitive And Duration Gaps The purpose of this chapter is to explore the options bankers have today for dealing with risk – especially the risk of loss due to changing interest rates – and to see how a bank’s management can coordinate the management of its assets with the management of its liabilities in order to achieve the institution’s goals.

2. Asset-Liability Management The Purpose of Asset-Liability Management is to Control a Bank’s Sensitivity to Changes in Market Interest Rates and Limit its Losses in its Net Income or Equity

3. Historical View of Asset-Liability Management • Asset Management Strategy • Liability Management Strategy • Funds Management Strategy

4. Interest Rate Risk • Price Risk • When Interest Rates Rise, the Market Value of the Bond or Asset Falls • Reinvestment Risk • When Interest Rates Fall, the Coupon Payments on the Bond are Reinvested at Lower Rates

5. Yield to Maturity (YTM)

6. Bank Discount Rate (DR) Where: FV equals Face Value

7. Market Interest Rates Function of: • Risk-Free Real Rate of Interest • Various Risk Premiums • Default Risk • Inflation Risk • Marketability Risk • Call Risk • Maturity Risk

8. Net Interest Margin

9. Goal of Interest Rate Hedging One Important Goal of Interest Rate Hedging is to Insulate the Bank from the Damaging Effects of Fluctuating Interest Rates

10. Interest-Sensitive Gap Measurements Dollar Interest-Sensitive Gap Interest-Sensitive Assets – Interest Sensitive Liabilities = Relative Interest-Sensitive Gap Interest Sensitivity Ratio

11. Interest-Sensitive Assets • Short-Term Securities Issued by the Government and Private Borrowers • Short-Term Loans Made by the Bank to Borrowing Customers • Variable-Rate Loans Made by the Bank to Borrowing Customers

12. Interest-Sensitive Liabilities • Borrowings from Money Markets • Short-Term Savings Accounts • Money-Market Deposits • Variable-Rate Deposits

13. Asset-Sensitive Bank Has: • Positive Dollar Interest-Sensitive Gap • Positive Relative Interest-Sensitive Gap • Interest Sensitivity Ratio Greater Than One

14. Liability Sensitive Bank Has: • Negative Dollar Interest-Sensitive Gap • Negative Relative Interest-Sensitive Gap • Interest Sensitivity Ratio Less Than One

15. Gap Positions and the Effect of Interest Rate Changes on the Bank • Asset-Sensitive Bank • Interest Rates Rise • NIM Rises • Interest Rates Fall • NIM Falls • Liability-Sensitive Bank • Interest Rates Rise • NIM Falls • Interest Rates Fall • NIM Rises

16. Zero Interest-Sensitive Gap • Dollar Interest-Sensitive Gap is Zero • Relative Interest-Sensitive Gap is Zero • Interest Sensitivity Ratio is One • When Interest Rates Change in Either Direction - NIM is Protected and Will Not Change

17. Important Decision Regarding IS Gap • Management Must Choose the Time Period Over Which NIM is to be Managed • Management Must Choose a Target NIM • To Increase NIM Management Must Either: • Develop Correct Interest Rate Forecast • Reallocate Assets and Liabilities to Increase Spread • Management Must Choose Dollar Volume of Interest-Sensitive Assets and Liabilities

18. NIM Influenced By: • Changes in Interest Rates Up or Down • Changes in the Spread Between Assets and Liabilities • Changes in the Volume of Interest-Sensitive Assets and Liabilities • Changes in the Mix of Assets and Liabilities

19. Cumulative Gap The Total Difference in Dollars Between Those Bank Assets and Liabilities Which Can be Repriced over a Designated Time Period

20. Aggressive Interest-Sensitive Gap Management

21. Problems with Interest-Sensitive Gap Management • Interest Paid on Liabilities Tend to Move Faster than Interest Rates Earned on Assets • Interest Rate Attached to Bank Assets and Liabilities Do Not Move at the Same Speed as Market Interest Rates • Point at Which Some Assets and Liabilities are Repriced is Not Easy to Identify • Interest-Sensitive Gap Does Not Consider the Impact of Changing Interest Rates on Equity Position

22. The Concept of Duration Duration is the Weighted Average Maturity of a Promised Stream of Future Cash Flows

23. To Calculate Duration

24. Price Sensitivity of a Security

25. Convexity The Rate of Change in an Asset’s Price or Value Varies with the Level of Interest Rates or Yields

26. Duration of an Asset portfolio Where: wi = the dollar amount of the ith asset divided by total assets DAi = the duration of the ith asset in the portfolio

27. Duration of a Liability Portfolio Where: wi = the dollar amount of the ith liability divided by total liabilities DLi = the duration of the ith liability in the portfolio

28. Duration Gap

29. Change in the Value of a Bank’s Net Worth

30. Impact of Changing Interest Rates on a Bank’s Net Worth

31. Limitations of Duration Gap Management • Finding Assets and Liabilities of the Same Duration Can be Difficult • Some Assets and Liabilities May Have Patterns of Cash Flows that are Not Well Defined • Customer Prepayments May Distort the Expected Cash Flows in Duration • Customer Defaults May Distort the Expected Cash Flows in Duration • Convexity Can Cause Problems
