European and Indian regulators are hoping to reach an eleventh-hour agreement that would allow European banks to continue trading in Asia’s third-largest economy.

HSBC, Royal Bank of Scotland, BNP Paribas, Barclays, Deutsche Bank, Standard Chartered, and Societe Generale are among the institutions that could find themselves affected by new European derivatives rules that prevent EU-domiciled banks from using foreign clearing houses that have not been rubber-stamped by EU authorities. Clearers sit in between a trade to guarantee the transaction in case either party defaults.
