The two entities are in talks for launching option contracts based on the US index at the Indian exchange.
According to persons familiar with the development, the discussions are currently on and a decision on the option contracts can be expected soon.
Thereafter, NSE would be free to launch futures and options on both S&P500 and DJIA. Incidentally, the current tie-up between NSE and CME Group allow the former to launch only futures contracts on DJIA.
"The partnership between NSE and CME (Group) is relatively new and hence the discussions (for options) are taking time," said a person familiar with the development.
"On the other hand, NSE has a long association with S&P and so the approvals for both futures and options based on S&P500 were received at the same time," he explained.
While NSE has already got all the regulatory approvals for launching futures based on S&P500 and DJIA, it has sought the capital market regulator's approval for options only on S&P500.
