The Globe and Mail reports in its Wednesday edition that chief executive officers at Canada's largest banks are optimistic about prospects for growth in the United States under a Donald Trump presidency, but are waiting for clearer signals. The Globe's James Bradshaw writes that promises of deregulation, infrastructure spending and rising interest rates have driven a sharp run-up in bank stocks. The uncertainty dogging Mr. Trump's transition to power comes when some of Canada's largest banks are eager to expand south of the border amid what they hope will be an improved U.S. business climate. Widespread uncertainty around trade rules threatens to dampen the prevailing optimism. Mr. Trump's threats to tear up the North American free-trade agreement and slap punitive tariffs on China and Mexico have spurred fears that a full-blown trade war could erupt. Bank of Nova Scotia boasts a large footprint in Mexico -- one of Mr. Trump's favourite rhetorical targets. "They're adapting to the rhetoric out of Washington, and we'll see what happens in terms of some revised negotiation on NAFTA, or whatever happens," CEO Brian Porter said. "But, look, the long-term economic prospects of Mexico remain intact."
