Exotic Options
Non-standard option contracts with payoff structures or activation conditions that differ from plain vanilla calls and puts, including barrier options, Asian options, lookback options, and digital options, traded in international OTC markets but not listed on Indian exchanges such as NSE.
Standard (plain vanilla) options — European calls and puts — have payoffs determined solely by the underlying asset price at expiration relative to the strike price. Exotic options modify this relationship in various ways, creating instruments whose payoffs depend on the path of the underlying price over time, on whether the price crosses certain barriers, on averages of past prices, or on combinations of these factors.
Barrier options are among the most commonly traded exotic options globally. A knock-in barrier option only comes into existence (becomes active) if the underlying price reaches a specified barrier level during the option's life. A knock-out option starts active but is extinguished if the price reaches the barrier. Barrier options are generally cheaper than plain vanilla options with the same strike because the activation or extinguishment condition reduces the expected payoff. They are widely used in structured currency hedges — an Indian exporter might buy a USD/INR put with a knock-out above the current spot level, paying a lower premium than for a plain vanilla put but accepting that the hedge disappears if the dollar strengthens too far.
Asian options (also called average price options) have payoffs based on the average price of the underlying asset over a specified period rather than the price at a single expiration date. An Asian call pays the maximum of zero and the difference between the average underlying price over the observation period and the strike. Asian options are popular for hedging commodity exposures where the hedger's economic exposure is to average prices (a refinery that buys crude throughout the month is naturally exposed to the month's average crude price, not the end-of-month price).
Lookback options have payoffs based on the maximum or minimum price achieved by the underlying during the option's life. A lookback call pays the difference between the maximum price achieved and the initial price; a lookback put pays the difference between the initial price and the minimum. Lookback options perfectly hedge the regret of not having transacted at the best possible price, but this benefit comes at a high premium cost.
Digital (or binary) options pay a fixed predetermined amount if a condition is met (for example, if the underlying price is above the strike at expiration) and zero otherwise, rather than a payoff proportional to the degree to which the option is in the money. These are discussed separately as binary options.
None of these instruments are listed for exchange trading in India. Sophisticated Indian corporates and banks access exotic options through the OTC market with global bank counterparties, governed by ISDA documentation and subject to RBI's regulations on offshore hedging transactions by Indian entities.
