Federal banking regulators will lose their powers to write consumer protection rules on July 21, 2011.
On that so-called transfer date, which was published Monday, such powers will be moved from the existing agencies to the new Consumer Financial Protection Bureau created under the Dodd-Frank Act.
The administration had until Monday to issue the transfer date.
The Treasury "secretary finds that designating July 21, 2011, as the transfer date will advance the mission of the CFPB and promote an orderly and organized startup," the administration wrote in the Federal Register.
Under Dodd-Frank, the consumer bureau gains rule-writing authority for the Truth in Lending Act, Home Mortgage Disclosure Act, Home Ownership and Equity Protection Act, Real Estate Settlement Procedures Act and other financial consumer protection laws.
On Friday, President Obama officially tapped Harvard professor Elizabeth Warren as assistant to the president and special adviser to Treasury Secretary Tim Geithner in charge of creating the CFPB.
