The document provides an overview of financial derivatives, including definitions and types. It discusses common derivative instruments such as forwards, futures, options, and swaps. Forwards and futures are agreements to buy or sell an asset at a future date, while options provide the right but not obligation to buy or sell. Swaps involve exchanging cash flows. Derivatives are used for hedging risks and discovering prices. While they provide benefits like risk management, criticisms include speculation and increased systemic risk. The derivatives market has evolved over centuries with early markets in rice and currencies, and modern exchanges in commodities, stocks and foreign exchange.
