Introduction to Derivatives for Actuarial Exams
Welcome to the foundational module on derivatives, a crucial topic for actuarial exams. Derivatives are financial contracts whose value is derived from an underlying asset. Understanding them is key to managing financial risk and pricing complex financial instruments.
What are Derivatives?
At their core, derivatives are agreements between two or more parties to buy or sell an asset at a predetermined price on a future date. The 'underlying asset' can be a stock, bond, commodity, currency, interest rate, or market index. Derivatives are not assets themselves but rather contracts that derive their value from these underlying assets.
Key Types of Derivatives
There are four main categories of derivatives, each with its own characteristics and applications:
| Derivative Type | Definition | Key Feature |
|---|---|---|
| Forwards | A customized contract between two parties to buy or sell an asset at a specified price on a future date. | Over-the-counter (OTC), non-standardized. |
| Futures | Similar to forwards but are standardized contracts traded on an exchange. | Exchange-traded, standardized, clearinghouse guarantees. |
| Options | Give the buyer the right, but not the obligation, to buy or sell an underlying asset at a specified price on or before a certain date. | Right, not obligation; premium paid. |
| Swaps | Agreements between two parties to exchange cash flows or liabilities from two different financial instruments. | Exchange of cash flows, often interest rates or currencies. |
Forwards and Futures: The Basics
Forwards and futures contracts are agreements to transact an asset at a future date for a price agreed upon today. The primary difference lies in their standardization and trading venue. Forwards are private, over-the-counter (OTC) agreements, while futures are standardized and traded on organized exchanges. This standardization in futures reduces counterparty risk through a clearinghouse.
Forwards are customized OTC contracts, while futures are standardized and exchange-traded.
Options: The Right, Not the Obligation
Options provide flexibility. A call option gives the holder the right to buy an asset, while a put option gives the right to sell. The buyer pays a premium for this right. The seller of the option receives the premium and is obligated to fulfill the contract if the buyer exercises their right. Understanding strike prices, expiration dates, and premiums is crucial.
Consider a call option on a stock. The underlying asset is the stock. The strike price is the price at which the option holder can buy the stock. The expiration date is the last day the option can be exercised. If the stock price is above the strike price at expiration, the option is 'in-the-money' and can be profitably exercised. If it's below, it's 'out-of-the-money' and likely won't be exercised. The premium is the price paid for the option contract itself.

Swaps: Exchanging Cash Flows
Swaps are agreements to exchange future cash flows. The most common types are interest rate swaps (exchanging fixed-rate payments for floating-rate payments) and currency swaps. They are typically used to manage exposure to interest rate or currency fluctuations.
For actuarial exams, focus on the mechanics of these derivatives, how their values change with underlying asset prices and time, and how they are used for hedging and speculation.
Why are Derivatives Important for Actuaries?
Actuaries work with financial risk daily. Derivatives provide powerful tools for:
- Hedging: Reducing exposure to adverse price movements in underlying assets.
- Risk Management: Quantifying and managing financial risks associated with insurance liabilities and investments.
- Product Development: Designing and pricing complex financial products, including those with embedded derivatives.
- Investment Strategy: Optimizing investment portfolios for return and risk.
Hedging and speculation.
Key Concepts for Exam Success
To excel in your actuarial exams, ensure you have a firm grasp of:
- Underlying Assets: What they are and how they influence derivative prices.
- Contract Specifications: Strike price, expiration date, notional amount.
- Payoff Profiles: How much profit or loss is realized under different scenarios.
- Pricing Fundamentals: Basic concepts of how derivatives are valued (though advanced pricing models are often separate topics).
- Risk Management Applications: How derivatives are used to mitigate specific financial risks.
