The Financial Post reports in its Saturday edition that regulators should rethink capital requirements imposed on Canada's largest financial institutions if banks in the United States and Europe are not forced to follow through with the strict final stages of the international risk management regime put in place following the 2008 financial crisis, the head of Canada's largest bank says. The Post's Barbara Shecter quotes RBC chief executive officer Dave McKay saying: "We cannot get out of sync with our two major competitive markets, Europe and America. A level playing field is really important." U.S. Federal Reserve chair Jerome Powell signalled an about-face on a plan to raise large bank capital requirements when he spoke before the U.S. Congress on March 6, saying significant changes would be made to the "Basel III end game" proposal, which encompasses an internationally agreed set of measures created in the wake of the 2008 financial crisis. His surprise statement followed pushback from banks in the U.S., which lobbied to avoid the final, most stringent stage of the protocol. Canada's Office of the Superintendent of Financial Institutions has updated its bank rules to reflect the final package of Basel III reforms.
