On Friday, BSE said that its newly launched Sensex and Bankex derivatives contracts traded a record Rs 528 crore in the first week of expiry on the exchange.

Futures traded at Rs 35 crore and options at Rs 493 crore, the exchange said in a release.

It added that the recently relaunched S&P BSE Sensex and S&P BSE Bankex derivatives contracts traded Rs 528 crore on the first weekly expiry on the BSE.

Since its launch, the BSE has seen a steady increase in volume and open interest in these contracts, which expire on Friday. According to the press release, these contracts saw wider participation of more than 125 members across India.

On Monday, the BSE restarted the Sensex and Bankex derivatives contracts to facilitate derivatives trading on the country’s major exchanges.

The relaunch of derivatives contracts was accompanied by reduced futures and options lot sizes and new expiration cycles on Friday and early Thursday.

Derivatives are considered high-risk-reward financial instruments designed to hedge against equity market risk.

The BSE first launched Sensex-30 derivatives (options and futures) in 2000. The Sensex-30 derivatives consist of the 30 largest and most actively traded companies on the exchange.
