Miller contended that these wills should provide regulators with the ability to break up large banks into a safer size. However, he was not adamant that banks be required to shrink, although he said he wouldn't object to it either.
"I support a direct approach, but am willing to consider nuanced approaches," he wrote.
He also threw his support behind an idea put forward by Sheila Bair, the former head of the FDIC. Bair has suggested that large, complex firms could be reorganized in a way that allows each of its subsidiaries to function as a separately managed legal entity. That way, if a portion of a bank began to face trouble, its impact could be easily isolated from the rest of the firm, reducing the danger.
"I urge that you not assume that the next financial crisis is decades or perhaps generations away in exercising your living wills authority," said Miller. "I urge that you assume that the financial system faces an exigent threat, because it may."
Support for breaking up the nation's largest banks has not broken cleanly down partisan lines. Both Sens.

Vitter, two others MORE (R-La.) have expressed support for the idea, as has Richard Fisher, president of the Federal Reserve Bank of Dallas. A common critique of Dodd-Frank among congressional Republicans is that it has failed to end the problem of "too big to fail" firms. However, many Republican lawmakers have argued that a strengthened bankruptcy regime is the proper course for addressing the issue, not splintering the biggest banks.
Many Dodd-Frank backers, including the White House, argue that the new law gives regulators the power to handle such massive firms, meaning that banks do not need to be broken up.
