After JPMorgan Chase revealed their Fail Whale trades, there was a debate over whether those trades would have been stopped by the Volcker rule, which was supposed to prevent proprietary trading by the mega-banks. Jamie Dimon called the trade a hedge, the authors of the Volcker rule disagreed with him, they leaned on the regulators to prevent this kind of risky activity from happening, and there was much debating. And it was supposed to end in July, with the final Volcker rule published and released by the regulators.
July 21 was the deadline, to be precise.
That was over two weeks ago.
