Federal regulators are proposing that the eight biggest U.S. banks be required to further increase the amount of capital they set aside to cushion against unexpected losses.

The global quality chief of Takata Corp. apologized and an official from Honda acknowledged the automaker broke a disclosure law as a Senate committee put the spotlight on a growing problem with exploding air bags.

Something about the deal smelled fishy.

Traders with nicknames like the “Three Musketeers” and the “A-Team” plotted over Internet chat rooms to manipulate currency markets for years, profiting at the expense of clients — and then congratulating themselves for their brilliance — regulators said Wednesday, as they fined five banks $3.4 billion.

Former top regulator Timothy Geithner defended terms of the US gov’t’s bailout of AIG, saying Wednesday that the insurance giant’s exceptionally risky behavior had caused losses that called for strict treatment.
