On December 11, 2014, the US House passed a bill repealing the Dodd-Frank requirement that risky derivatives be pushed into big-bank subsidiaries, leaving our deposits and pensions exposed to massive derivatives losses. The bill was vigorously challenged by Senator Elizabeth Warren; but the tide turned when Jamie Dimon, CEO of JPMorganChase, stepped into the ring. Perhaps what prompted his intervention was the unanticipated $40 drop in the price of oil. As financial blogger Michael Snyder points out, that drop could trigger a derivatives payout that could bankrupt the biggest banks. And if the G20's new "bail-in" rules are formalized, depositors and pensioners could be on the hook.
