12.3 Hedging Strategies and Instruments

A hedging strategy matches an identified exposure with an offset whose payoff responds appropriately over the required horizon. Instrument choice follows the objective. A firm seeking certainty may prefer a locked price; one seeking downside protection while retaining upside may prefer an option; one lacking derivative capability may reduce or naturally offset the exposure.

Forwards and futures

A forward contract is a bilateral agreement to buy or sell an asset or currency at a specified future date and price. Terms can be customized, but the parties bear counterparty, documentation, valuation, and collateral risk. A dollar payable can be hedged by agreeing to buy dollars forward; a dollar receivable can be hedged by selling dollars forward.

A futures contract is standardized and traded through an organized market with clearing, margin, and daily marking to market. Clearing reduces bilateral counterparty exposure but does not remove risk. Daily variation margin creates liquidity needs, and contract size or expiry may not match the underlying exposure, producing basis and rollover risk.

For a bond portfolio, selling interest-rate or government-bond futures can offset losses from rising yields. The number of contracts should reflect value and duration sensitivity, not only principal amount.

Options

An option gives the buyer a right, not an obligation, in exchange for a premium. A call gives the right to buy; a put gives the right to sell. The seller or writer has the corresponding obligation if exercised.

• An investor holding shares can buy a protective put to set a downside floor while retaining upside above the premium cost.
• A firm needing a foreign currency can buy a call on that currency, establishing a maximum effective purchase price while retaining benefit if the currency weakens.
• An issuer exposed to rising borrowing rates can use a cap or appropriate option structure to limit the maximum rate.

Options have nonlinear payoffs. Their sensitivity changes with the underlying price, time, volatility, and rates, so a hedge may need rebalancing. Premium is a known cost but not evidence that the strategy failed.

Swaps

An interest-rate swap exchanges interest cash flows, commonly fixed for floating, on a notional amount. A floating-rate borrower that wants payment certainty can pay fixed and receive floating, offsetting the floating component of its debt. A fixed-rate borrower seeking floating exposure can take the reverse side.

A currency swap exchanges cash flows in different currencies and may include principal exchanges. It can address longer-term funding exposure but introduces counterparty, collateral, legal, and cross-currency basis risk. The notional generally measures cash flows and is not automatically the amount at risk.

Natural and balance-sheet hedges

A natural hedge aligns operating inflows and outflows. A company earning dollars may fund part of its dollar expenses or debt with those receipts. Maturity matching, asset-liability management, supplier or customer contract terms, and geographic diversification can also reduce net exposure.

Natural hedges can be cheaper and simpler but may be unstable if revenue falls or timing differs. Borrowing in a foreign currency merely to create an accounting offset can add refinancing and credit risk.

Diversification, limits, and reduction

Not every risk requires a derivative. Diversification reduces idiosyncratic concentration but does not remove system-wide market risk. Position limits cap exposure before it grows. Rebalancing, selling part of a position, shortening duration, holding liquidity, or declining a transaction may be the clearest treatment.

Strategy matching

Implementation controls

Verify legal authority, permitted instruments, exposure evidence, suitability, limits, counterparty approval, master agreements, collateral terms, independent price verification, confirmations, settlement, accounting review, and reporting. Front-office execution should be separated from confirmation, valuation, collateral, and reconciliation.

Performance should be assessed on the combined hedge and underlying exposure. If a put gains during a market fall while the protected shares lose more, the gain is doing its job even though the total position may still decline. Conversely, a profitable derivative can conceal failure if it was not linked to the approved exposure.

Exam method

For a payable, determine what must be bought; for a receivable, what will be sold. Match direction, amount, and horizon. Remember that forward and futures payoffs are broadly symmetric, while an option buyer has asymmetric protection for a premium. Include residual basis, liquidity, and counterparty risks in the answer.
