Trading venue MarketAxess has asked regulators to make the trading of some credit default swaps on electronic platforms mandatory, as US market participants prepare for new over-the-counter derivatives rules due to come in early next year.

The firm joins rival market operator Tradeweb in submitting the list of credit derivatives it believes should be subject to rules in the Dodd-Frank Act that require OTC derivatives to be traded on platforms, known as swap execution facilities, or SEFs.
