Open Interest

Definition

Open Interest refers to the total number of outstanding contracts that are still active in a commodity or options market. These contracts must not have been exercised, closed out, or allowed to expire. Open interest provides useful information regarding the liquidity and activity in the market, often serving as an indicator of the strength or weakness of current market trends.

Examples

  1. Commodities Market: Assume there are 100 oil futures contracts currently open at the end of a trading day. The open interest, in this case, is 100 contracts. If 10 of these contracts are closed the next day, the new open interest would be 90 contracts.

  2. Options Market: Suppose investors hold 200 call options on a particular stock. These options remain open and have not been executed. The open interest is 200. If later, 50 of these options are executed, the open interest reduces to 150 contracts.
