• Regulatory Constraints on Bank Leverage: Issues and Lessons from the Canadian Experience

  Staff Discussion Paper 2009-15 Étienne Bordeleau, Allan Crawford, Christopher Graham

  The Basel capital framework plays an important role in risk management by linking a bank's minimum capital requirements to the riskiness of its assets. Nevertheless, the risk estimates underlying these calculations may be imperfect, and it appears that a cyclical bias in measures of risk-adjusted capital contributed to procyclical increases in global leverage prior to the recent financial crisis.

• Testing for Financial Contagion with Applications to the Canadian Banking System

  Staff Working Paper 2009-14 Fuchun Li

  The author proposes a new test for financial contagion based on a non-parametric measure of the cross-market correlation. The test does not depend on the assumption that the data are drawn from a given probability distribution; therefore, it allows for maximal flexibility in fitting into the data.
