On the contrary, Section 165 of the Dodd-Frank Act gives the Federal Reserve the authority, and the obligation, to apply regulations of increasing stringency to large banking organizations in order to mitigate risks to financial stability. In any event, it is unlikely that the problems associated with too-big-tofail institutions can be efficiently ameliorated using a single regulatory tool.
The explicit expectation in Section 165 that there will be a variety of enhanced standards seems welladvised.
