Speaking in London last night, the Mayor of New York, Michael Bloomberg, called for greater transparency to break the cycle of uncertainty. In Haberdashers' Hall in the City last night, Mr Bloomberg said: "[Lack of transparency] is a big reason not only for the panics that our countries have experienced but also for the freezing up of credit markets. We simply don't know the value of the assets that financial institutions are holding." Greater transparency would help restore the confidence the market needs.
