The Globe and Mail reports in its Wednesday, April 9, edition that oil is trading at its lowest levels in nearly four years, raising concerns on Wall Street that President Trump's trade policies could lead the U.S. into a recession. A New York Times dispatch to The Globe reports that despite this, oil and gas executives have kept mostly silent, aiming to maintain good relations with the President. In private, they have expressed concerns about the uncertainty caused by his tariffs, as noted in a survey by the Federal Reserve Bank of Dallas. If U.S. oil prices fall below $60 (U.S.) a barrel, companies may need to cut drilling, spending and potentially lay off workers, especially in states like Texas. Oil executives donated millions to elect Mr. Trump, who has supported the industry. However, recent events suggest that a friendly relationship in the White House has its limits. Oil prices have plunged, as have energy company stocks. By the end of the trading day Monday, shares in Exxon Mobil and Chevron, the largest U.S. oil companies, had fallen about 13 per cent and 16 per cent since Wednesday, when Mr. Trump announced his latest tariffs. Neither company made its CEO available for an interview.
