This paper discusses important issues associated with mandating the use of swap execution facilities (SEFs) for executing certain OTC derivatives products. It asserts that such mandates should be structured in a way that preserves the OTC derivatives market’s strengths while addressing its weaknesses, presents a set of desirable SEF characteristics to meet this objective and identifies relatively modest infrastructure and transparency benefits that SEFs might bring. The paper also analyzes the proposed rules of the CFTC and the SEC required by the Dodd-Frank Act (DFA).
