A financial futures contract is an agreement to buy or sell a financial asset like a stock, bond, currency, or index at a predetermined price and date. These contracts are standardized and traded on an exchange. There are several types of financial futures including interest rate futures, foreign currency futures, stock index futures, and bond index futures. Participants in the futures market include hedgers who aim to reduce risk, speculators who try to earn profits from price movements, arbitrageurs who seek riskless profits from pricing discrepancies, and spreaders who take positions to lower risk. The key functions of futures markets are hedging risk, price discovery, financing, providing liquidity, and stabilizing prices.
