Business Report BEFORE THE BELL: Commodity prices slip with Chinese currency; CP Rail earnings expected to boost Bay Street SHARE ON: James Bowler, contributor, Thursday, Jul. 19th, 2018 Commodity prices are weighted by a suffering Chinese economy affected by trade war worries. The price of industrial and precious metals, used heavily in China, are all sliding. This comes as China’s currency slides to a one-year low as a trade war with the US grows further. Canada may be in US sights again as White House officials probe uranium trade as a national security threat, the same tactic used to put tariffs on Canadian steel and aluminum. Bay Street may get a boost today though as CP Rail reported better than expected earnings with jumps in grain and oil shipments. Meanwhile, US crude continues to slide to 66.99 a barrel as inventories reports send mixed messages to investors. The Loonie is down to 75.49 cents US.
