WASHINGTON, Aug 5 (Reuters) - U.S. regulators warned Wall Street banks on Tuesday to improve plans that spell out how they would avoid taxpayer bailouts during a future crisis or face tough repercussions, including being forced to break up their businesses.
Six years after the financial crisis, the Federal Deposit Insurance Corp and Federal Reserve said the so-called living wills 11 big banks submitted last year were overly optimistic, allowed banks to be too complex, and would not enable them to go through bankruptcy without government support.
“The plans provide no credible or clear path through bankruptcy that doesn’t require unrealistic assumptions and direct or indirect public support,” said Thomas Hoenig, second in command at the FDIC.
The 11 banks sent in living wills for the third time this year, laying out how they could enter bankruptcy without causing the mayhem that triggered costly government bailouts in 2008.
These plans, often thousands of pages thick, range from mundane data as where to reach key staff to complex discussions of how to unwind legal entities in the United States and abroad.
But the FDIC said on Tuesday it had decided the second set of plans, submitted in 2013, were “not credible.” The Fed did not take quite as harsh a tone, but both warned that the plans needed considerable work.
Banks also submitted a round of living wills in July 2014, but regulators were still evaluating the previous submission. Their comments on Tuesday only covered the 2013 documents.
If banks’ 2015 plans do not address the criticisms, both agencies said they would declare that the plans did not meet the requirements of the 2010 Dodd-Frank Act.
Firms would have a formal period to correct problems if their living wills were deemed deficient by both regulators, who could then tell banks to cut down their business after two years if things did not improve, a senior Fed official said.
The regulators did not publicly disclose problems with individual 2013 plans, although they sent the banks private letters spelling out the issues.
The submissions included unrealistic assumptions about the likely behavior of customers and others and failed to identify the changes in the structure of their firms that would enable such an “orderly resolution,” the regulators said.
They said the banks across the board need to simplify legal structures and change financial contracts to avoid an exodus of trading partners during insolvency.
The banks also need to develop a holding company structure to support resolvability, make sure that they could continue to use shared services during insolvency, and work on producing reliable data quickly, the Fed and FDIC said.
Banks had complained they did not get enough feedback from regulators on the living wills. Regulators’ tough language surprised some industry observers on Tuesday.
“It would seem to be incongruous to make a determination of ‘not credible’ without having provided feedback really on the first or second times companies filed their plans,” said Mike Krimminger, a former FDIC official who is now a partner at Cleary Gottlieb Steen & Hamilton in Washington.
