This module delves into the practical application of derivatives for managing financial risk. We will explore how futures, forwards, options, and swaps can be strategically employed to hedge against adverse price movements in underlying assets.

Hedging is a risk management strategy used to offset potential losses or gains that may be incurred by a companion investment. In essence, it's like taking out an insurance policy on your financial positions. Derivatives are powerful tools for hedging because their value is derived from an underlying asset, allowing for precise risk transfer.

Futures and forwards contracts obligate the buyer to purchase and the seller to sell an asset at a predetermined future date and price. They are commonly used to hedge against price fluctuations in commodities, currencies, and interest rates.

Options provide the right, but not the obligation, to buy or sell an underlying asset at a specified price (the strike price) on or before a certain date. This flexibility makes them valuable for hedging, especially when the direction of price movement is uncertain.

A common hedging strategy with options is to buy a put option to protect against a price decline in an asset you own. If the asset's price falls below the strike price, you can exercise the put option to sell the asset at the higher strike price, limiting your loss. If the price rises, you can let the option expire worthless and benefit from the higher market price, having only lost the premium paid for the option.

Swaps are derivative contracts where two parties agree to exchange cash flows or liabilities from two different financial instruments. Interest rate swaps and currency swaps are widely used for hedging.

When designing a hedging strategy, several factors are crucial:

• Basis Risk: The risk that the price of the hedging instrument does not move perfectly in line with the price of the asset being hedged.
• Cost of Hedging: The premiums paid for options, transaction costs, and potential opportunity costs.
• Effectiveness: How well the hedge reduces the intended risk without introducing new ones.
• Over-hedging/Under-hedging: Hedging too much or too little of the exposure.

Let's consider a few scenarios:

• Airline Hedging Fuel Costs: An airline can buy call options on jet fuel to protect against rising fuel prices. If fuel prices increase significantly, the airline can exercise its call options to buy fuel at a lower, predetermined price. If prices fall, they can let the options expire and buy fuel at the lower market rate.
• Portfolio Manager Hedging Equity Exposure: A portfolio manager holding a large equity portfolio can sell stock index futures to hedge against a market downturn. If the market falls, the losses on the portfolio are offset by gains on the short futures position.
• Importer Hedging Currency Risk: An importer who needs to pay for goods in Euros in three months can buy a forward contract to lock in the USD/EUR exchange rate today, protecting against a depreciation of the USD.
