Critic: CFPB Regulations Ensure Fannie, Freddie Market Dominance. The Consumer Financial Protection Bureau, through its scores of regulations, has stifled and discouraged mortgage market growth away from the GSEs, a critic of the bureau noted during the CFPB’s third anniversary last week. “One of the important effects of the CFPB has been to ensure the continuing market dominance of Fannie Mae and Freddie Mac by the way they have written their mortgage regulations, which give you a pass if you make a loan eligible for sale to Fannie or Freddie or give you very onerous legal risks if you don’t,” said Alex Pollock, a resident fellow at the American Enterprise Institute.
