The Basel Committee on Banking Supervision recently agreed to subject systemically important financial institutions to increased capital requirements based on their risk-weighted assets. However, there are concerns about how banks calculate those assets. "There is no question that the weightings can be manipulated," said Charles Goodhart, a former policymaker at the Bank of England. "They are light-years away from being scientific. The idea that risk can be captured and then not adjusted to reflect dynamic markets is absolutely flawed."
