  • CUSMA negotiations collapsed on August 21, with both sides trading blame. As a result, 50% tariffs on auto parts, steel, trucks and cars will take effect January 1, 2027, and Canada announced retaliatory 50% tariffs on more than 700 US products effective September 8.
  • Despite the escalating tariff rhetoric, USDCAD traded with minimal reaction, suggesting markets still viewed a resolution as eventually forthcoming.
  • USD weakened through August as deteriorating US labour data—nonfarm payrolls declining against expectations for positive prints—and recalibrated Fed expectations triggered a sustained selloff.

  • US–Iran tensions oscillated throughout August, shifting from a potential breakthrough to Trump’s sanctions announcement, with China threatened with exclusion from the US dollar clearing system for purchasing Iranian oil.
