Giving the Treasury secretary authority the power to seize a broader range of companies would mark a significant shift from the existing model of financial regulation, which relies on independent agencies that are shielded from the political process. The Treasury secretary, a member of the president’s Cabinet, would exercise the new powers in consultation with the White House, the Federal Reserve and other regulators, according to an internal administration document…

The administration’s proposal contains two pieces. First, it would empower a government agency to take on the new role of systemic risk regulator with broad oversight of any and all financial firms whose failure could disrupt the broader economy. The Federal Reserve is widely considered to be the leading candidate for this assignment. But some critics warn that this could conflict with the Fed’s other responsibilities, particularly its control over monetary policy.

The government also would assume the authority to seize such firms if they totter toward failure.
