USD/CAD closed at 1.4138 on Thursday, meaning the Canadian dollar bought 70.73 US cents, its weakest level in almost seven weeks. The loonie has weakened in nine of the last ten sessions, moving from 1.3859 on September 12 to 1.4138 on September 24, a decline of more than 2 percent in under two weeks.

The shaded region marks the final four sessions of the run, during which the Canadian dollar extended its slide to a fresh seven-week low against the US dollar.

Why the CAD Moved Against the Oil Story Today

Currency direction usually tracks oil when energy makes up as much of the index as it does on the TSX, and WTI crude actually rose 1.97 percent Thursday to 93.98 US dollars. The loonie fell anyway. The mechanism running the currency this week is not oil. It is the widening gap between Canadian and US policy rates.

The Federal Reserve raised its target range a quarter point to 3.75 to 4.00 percent on September 16, the first US increase since 2023, under a notably hawkish Chair Kevin Warsh. The Bank of Canada has not moved since its October 2025 cut, holding at 2.25 percent through seven straight decisions including September 2. A 175 basis point gap between the two currencies rates pulls capital toward the higher yielding US dollar, and that flow is showing up directly in the currency pair, independent of what oil is doing on any given day.

The TSX Absorbed a Smaller Hit Today After Wednesday Steep Drop

The S&P/TSX Composite Index closed at 35,706.46 Thursday, down 44.97 points, a modest move compared with Wednesday 584-point decline, the index sharpest single session loss in more than three months. That larger move traced to a sharp reversal in copper, gold and silver prices, which hit mining names including Teck Resources, Ivanhoe Mines and Agnico Eagle Mines hard earlier in the week.

Thursday brought a clearer sector split. Energy stocks gained as WTI firmed, while materials stayed under pressure from the same higher-yield dynamic weighing on the currency. A rising US dollar makes US-denominated gold and copper less attractive to hold, compounding the pressure already coming from higher bond yields.
