US officials are discussing trade agreements with the EU and a group of Asian-Pacific countries. Treasury Secretary Jack Lew has vowed to prevent the deals from weakening financial regulation, including derivatives rules. "We will not allow these agreements to serve as an opportunity to water down domestic financial regulatory standards," Lew said. SIFMA says including financial services could improve efficiency of rules across borders. "There is no evidence that the Europeans are watering down their new regulatory scope," according to SIFMA.
