PARIS, more used to staging fashion shows, put on a celebrity catwalk of central bankers today. The line-up of big names at a glitzy hotel in the heart of the French capital stretched from Ben Bernanke of the Fed to Zhou Xiaochuan of China, with Mervyn King of the Bank of England, Masaaki Shirakawa of the Bank of Japan and Jean-Claude Trichet of the European Central Bank. Hosting the event—on global imbalances and financial stability—was Christian Noyer of the Bank of France.
