US Equity Futures Lower as Traders Assess Rising Oil, Canadian Retaliatory Tariffs

07:59 AM EDT, 09/08/2026 (MT Newswires) -- US equity futures were lower pre-bell Tuesday, coming off a three-day weekend as traders assessed rising oil prices and Canada's retaliatory tariffs against the US. Dow Jones Industrial Average futures were 0.8% lower, S&P 500 futures were down 0.3%, and Nasdaq futures were off 0.1%. Canadian tariffs, which were announced after trade talks with the US collapsed last month, took effect on Tuesday and range from 15% to 50%, impacting hundreds of US products, including dairy, agricultural equipment, paper, household appliances and electronics. US President Donald Trump, in a Monday post on Truth Social, called for a boycott of Canadian aerospace manufacturer Bombardier, saying "If they want our Market, they must build here, and stop treating America like a 'piggybank'". In response, the company told CNBC that its workers are based all over the US, with sites in 10 states, while its aircraft are constructed using US-made components. Oil prices were higher, with front-month global benchmark North Sea Brent crude up 1.8% at $98.73 per barrel and US West Texas Intermediate crude 2.7% higher at $93.91 per barrel. The National Federation of Independent Business' monthly Small Business Optimism Index fell to a reading of 98.7 in August from 99.8 in July.
