(NEWSER) – The scandal over rigged Libor rates, the benchmark rate used for interest rates on trillions of dollars worth of loans, is quickly growing past Barclays and threatens to engulf the Bank of England and a dozen other banks, including several in the US, reports the Wall Street Journal. Barclays officials had hoped the early deal it reached with US and British regulators, admitting guilt and taking a $453 million fine, would spare it from the worst of the scandal’s fallout. But even with the resignation of top Barclays execs including CEO Bob Diamond in recent days, outrage is growing. Diamond was grilled by a parliamentary inquiry yesterday. “Either you were complicit, grossly negligent, or incompetent,” a Labour lawmaker told him.
