Banks won the delay to fully meet the so-called liquidity coverage ratio, or LCR, following a deal struck by regulatory chiefs meeting yesterday in Basel, Switzerland. They’ll be able to pick from a longer list of approved assets including equities and securitized mortgage debt as they seek to build up buffers of liquidity for use in a financial crisis.
