An offsetting transaction is a financial trade that cancels out or neutralises the risk or position of an existing open trade — effectively closing an existing exposure by entering into an equal and opposite transaction on the same underlying instrument. In futures markets, a long futures position is offset by selling (going short) an equivalent futures contract at the current market price — eliminating the obligation to take delivery without physically closing through the exchange's settlement process. In options markets, a long call option is offset by selling an equivalent call option at the same strike and expiry. Offsetting transactions are the primary mechanism by which traders and institutional investors manage and close derivatives positions in Indian F&O markets — the vast majority of NSE and BSE derivatives positions are closed through offsetting transactions before expiry rather than through physical or cash settlement at the final settlement date. For corporate hedgers, offsetting a forward currency contract before maturity — by entering into a reverse forward at the current forward rate — locks in the gain or loss on the original hedge, effectively closing the currency risk management position. The profit or loss on an offsetting transaction equals the difference between the original entry price and the offsetting price, minus transaction costs.
