Federal agencies implementing the Dodd-Frank Act have missed most of their deadlines, but a Treasury official said they are more focused on getting the rules right. "We want quality and speed, but we’re not going to sacrifice quality for speed," said Deputy Treasury Secretary Neal Wolin. "We want to make sure that we do these rules in a thorough way." Industry insiders have raised concerns about the proposed rules. Ken Bentsen, executive vice president for public policy at SIFMA, said market participants are worried they could be penalized for trades they thought were legal. "What you think was allowed, you find out in the rearview mirror that it was not allowed," he said.
