Deutsche Bank CEO Calls for Global Banking Rules at Davos

Josef Ackerman, CEO of Deutsche Bank, told CNBC's Maria Bartiromo his views on recent bank regulation proposals at the World Economic Forum in Davos yesterday. "We're in a global market, we need global rules," Ackerman said, suggesting that President Obama's recent proposal to separate banks from the capital markets might not work if only one country adopts it. Ackerman supports the Basel II capital allocation requirements, but feels the Volcker rule could reduce liquidity and efficiency in the global markets.
