Global central bank chiefs gave lenders four more years to meet international liquidity requirements and watered down the measures in a bid to stave off another credit crunch.

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.

“This was a compromise between competing views from around the world,” Bank of England Governor Mervyn King said at a briefing following yesterday's meeting. King chairs the Group of Governors and Heads of Supervision, or GHOS, which decides on global bank rules. “For the first time in regulatory history we have a truly global minimum standard for bank liquidity.”
