2. J. K. Dietrich - FBE 524 - Fall, 2005 Interest rate risk u Future interest rates will affect value of all assets and liabilities, both real and financial assets and financial liabilities u No one knows future interest rates –Predictions of econometric models and the Lucas critique –Supply and demand factors (e.g. bond calendar) reflect expectations used in planning –Rational expectations and market rates

3. J. K. Dietrich - FBE 524 - Fall, 2005 Interest Rate Risk u Interest rates change constantly –Each element of rates change: real rate, inflation premium, term premium, and risk premium –Market participants have varying degrees of sensitivity to changes in components of rates u One way to view interest-rate risk is in terms of balance sheet risk

4. J. K. Dietrich - FBE 524 - Fall, 2005 Balance Sheet Risk Real Assets Inventories Equipment Plant Land Financial Assets Receivables Money Bonds Stock Financial Liabilities Payables Short-term notes Mortgages Bonds Preferred stock Common Stock AssetsLiabilities and Equity Increasing duration

5. J. K. Dietrich - FBE 524 - Fall, 2005 Hedging Balance Sheet Risk u Hedging on balance sheet –Matching duration of assets and liabilities: –Changing duration of assets and/or liabilities through swaps –Floating rate securities with short re-pricing intervals have short durations u Hedging off balance sheet –Futures, forward contracts, and options Weighted average asset duration = Weighted average liability duration

6. J. K. Dietrich - FBE 524 - Fall, 2005 Swaps u Exchange of future cash flows based on movement of some asset or price –Interest rates –Exchange rates –Commodity prices or other contingencies u Swaps are all over-the-counter contracts u Two contracting entities are called counter- parties u Financial institution can take both sides

9. J. K. Dietrich - FBE 524 - Fall, 2005 Definition of Derivatives u Derivatives are contracts –Commit parties to certain actions/payments in the future –The payment/action depends on outcomes of pre-specified events in the future u In most cases, the major cash flow or costly action will or may occur in the future, not in the present u Contracts can be standardized or negotiated

10. J. K. Dietrich - FBE 524 - Fall, 2005 Types of Derivative Contracts u Three basic types of contracts –Futures or forwards –Options –Swaps u Many basic underlying assets –Commodities –Currencies –Financial assets like fixed incomes or residual claims

11. J. K. Dietrich - FBE 524 - Fall, 2005 Derivatives = Value Derived from Prices of Other Assets u Stock market or equity price, commodity price, exchange and interest rate derivatives u Swaps, forwards and futures, options, and swap-options (or swaptions) u Traded and over-the-counter derivatives u Derivative are a zero-sum game u Credit risk in derivatives is performance risk, not notional value risk

12. J. K. Dietrich - FBE 524 - Fall, 2005 Exposure to Risk u A general term to describe a firm’s exposure to a particular risk (e.g. a commodity price) is to classify the exposure as long or short u Long exposure means that the firm will benefit from increases in prices or values u Short exposure means that the firm will benefit from decreases in prices or values

13. J. K. Dietrich - FBE 524 - Fall, 2005 Long Exposure u A firm (or individual) is long if at the time of the risk assessment if it has or will have an asset or commodity. As examples –The firm owns assets, as in inventories of raw materials or finished goods –The firm produces a commodity or product, as in an agribusiness raising wheat or livestock –The firm will take possession in the future or a commodity or an asset –The firm has bought a commodity or asset

14. J. K. Dietrich - FBE 524 - Fall, 2005 Short Exposure u A firm (or individual) is short if at the time of the risk assessment if it needs or will need an asset or commodity. As examples –The firm is planning or has promised to deliver raw materials or finished goods –The firm uses a commodity or product in production as inputs, like steel or lumber –The firm will have possession in the future or a commodity or an asset it does not need or needs to sell –The firm has sold a commodity or asset and must deliver

15. J. K. Dietrich - FBE 524 - Fall, 2005 Exposure to Risks

16. J. K. Dietrich - FBE 524 - Fall, 2005 Examples of Exposure u Farmer with wheat is long wheat u Honey Baked Ham is short pork before Easter selling season u Treasurer with excess cash in three months is short investments u Company needing cash in nine months is long financial assets (its liabilities are others’ assets) to sell

Dietrich - FBE 524 - Fall, 2005 Forward vs. Futures Contracts u Bilateral contract (usually with a financial firm as counter-party) u Terms are tailor made to needs of client, not standardized u No exchange of cash until maturity of contract u Over-the-counter market not as liquid as organized exchange

20. J. K. Dietrich - FBE 524 - Fall, 2005 Managing Risk with Futures u Offset price or interest rate risk with contract which moves in opposite direction u “Cross diagonally in the box” u Identify contract with price or interest rate which moves as close as possible with the price or interest rate exposure u Imperfect correlation is basis risk u Not using futures or forwards can be speculation
