Benjamin Lawsky, New York’s aggressive banking regulator who is campaigning to clean up Wall Street, is turning his sights on the individuals as well as the institutions who squeeze struggling homeowners or help banks violate US sanctions.

“Corporations are a legal fiction. You have to deter bad individual conduct within corporations,” said Mr Lawsky, superintendent of NY’s Department of Financial Services, in an interview with the Financial Times. “People who did the conduct are going to be held accountable.”

Mr Lawsky’s name and shame strategy taps into a wave of popular discontent in the US and Europe over the fact that few individual bankers have been personally sanctioned for the bad decisions that led to the global financial crisis. Taxpayers have been forced to stump up hundreds of billions of dollars to rescue banks brought low by reckless behaviour.
