A year after US investment bank Lehman Brothers collapsed, a British think tank is warning the lessons of the crisis have not been learned.
The Institute for Public Policy Research (IPPR) says a rapid return to the bonus culture in the financial sector shows that real reform has been "very limited".
The warnings echoed a speech by United States President Barack Obama, who warned of complacency in the banking sector, the BBC reports.
British Prime Minister Gordon Brown has also said there was "unfinished business" with banks.
Lehman Brothers, once the fourth-largest American investment bank, filed for bankruptcy protection in September 2008.
Governments around the world subsequently had to pump trillions into their financial systems to save their economies from collapse.
