The Globe and Mail reports in its Wednesday edition that U.S. President Donald Trump is on a crusade to punish banks that purportedly discriminate against his supporters, and is co-opting the Office of the Comptroller of the Currency, or OCC, America's national banking regulator, to do his bidding. The Globe's Rita Trichur writes that OCC has stopped supervising banks for reputational risks that result in scandals or financial losses. Instead, the OCC is actively hunting for evidence that banks rejected customers or shuttered accounts for religious or political reasons. Not only is the U.S. the main growth market for Canadian banks, but their home-country regulator, the Office of the Superintendent of Financial Institutions, or OSFI, is maintaining its focus on reputation risks. That OSFI guideline requires lenders to have appropriate policies and procedures to guard against threats to their integrity. Last Wednesday, the OCC released the preliminary findings of its review of debanking activities by JPMorgan Chase, Bank of America, Citibank, Wells Fargo, U.S. Bank, Capital One, PNC Bank and the U.S. arms of TD and BMO. The OCC failed to provide specific examples of malpractice at any of those financial institutions.
