The Globe and Mail reports in its Wednesday edition that the impending trade war with the United States has not yet roiled oil markets, but uncertainty about what is next still looms over the sector at the start of a 30-day tariff reprieve. The Globe's Emma Graney and Jeffrey Jones write that includes where crude might end up should demand ease from U.S. refiners, redirecting product to the Asian market as American companies baulk at higher costs stemming from a 10-per-cent tariff on Canadian oil. On the weekend, President Donald Trump said he would impose 25-per-cent tariffs on imports from Canada and Mexico, with a lower 10-per-cent tariff for Canadian energy imports. Analysts are surprised that markets have not moved much in response to the tariffs. Even the slight bump to the Canada-U.S. differential is less than expected -- about $14.50 (U.S.) per barrel on Monday, down from $16.25 (U.S.) a barrel on Friday. Tariffs on oil will likely be short-lived. Scotiabank analysts said inflationary pressure on U.S. energy costs simply would not allow a prolonged hit. The tariffs will result in a surplus of crude and refined products in Canada and Mexico, while driving shortages in the U.S. as the two countries redirect crude.
