According to Petrasic, this means that the regulators have been purposely vague, so that "near term and short term can be as long or short as they care to make it, depending on the circumstances."

During the comment period, "there will be a desire for as much of a bright line as possible," he said.

Petrasic went on to say that at this point, "everybody's focused on proprietary trading," since the Volcker Rule's ban on private equity and hedge fund investments, with certain exceptions, is much easier to understand.

"The proposal represents the agencies' understanding that daylight is needed for banks to be able to understand what the requirements are. At this point the regulators recognize that they are driving through fog," he said.

Frank A. Mayer, III -- a partner in the Financial Services Practice Group of Pepper Hamilton LLP - said that the lengthening of the comment period and the "350 questions" asked by regulators in the prosed rules mean that "the regulators are having difficulty defining precisely in their rule making what is impactful to safety and soundness of insured depository institutions" regarding "mitigation hedging activities for customers and the financial institution."

"I predict this will end up being a compliance issue at the institutional level with roughly hewn safe harbors," he said.
