The TSX Composite closed at 36,336, up 329 points or 0.91% on Tuesday, September 22, 2026 — a session defined by violent cross-currents that ultimately resolved in the bulls’ favour. Volume was heavy and broad, with materials and mining names doing the heavy lifting while the energy patch endured one of its worst single-session drops of the year. South of the border, the S&P 500 was dead flat at 7,765 and the NASDAQ edged up 0.45% to 27,244, leaving Canada as the standout performer among North American benchmarks today.
Winners: Materials and Metals Steal the Show
Copper was the commodity story of the day, surging 3.23% to US$6.9025/lb (approximately C$9.69/lb at today’s USD/CAD rate of 1.4044) on a combination of tightening supply data out of Chile and fresh demand signals from China’s manufacturing sector. That move lit a fire under Canadian base-metals producers. Teck Resources (TECK.B) was among the session’s biggest large-cap winners, with the stock climbing sharply in sympathy with the copper move. First Quantum Minerals (FM) and mid-cap copper explorers on the TSX-V also posted outsized gains, with several junior names up 5–9% on the day.
Gold added to its already historic run, rising 0.38% to US$4,400.60/oz (C$6,179/oz) — a new psychological milestone that kept the senior gold producers bid throughout the session. Agnico Eagle Mines (AEM) and Barrick Gold (ABX) both closed meaningfully higher, extending their year-to-date outperformance. Silver was the precious-metals standout, however, rocketing 2.91% to US$67.74/oz (C$95.12/oz) and propelling silver-levered names on the TSX and TSX-V to multi-week highs.
Losers: Energy Takes a Brutal Broadside
WTI crude oil collapsed 6.29% to US$89.76/bbl, one of the sharpest single-day drops in months, after U.S. inventory data showed a surprise crude build of 4.7 million barrels — well above the 1.2 million barrel draw that the market had expected. Brent fell a comparatively modest 1.91% to US$98.42/bbl, but the WTI move was enough to hammer Canadian oil sands and intermediate producers. Cenovus Energy (CVE) and Canadian Natural Resources (CNQ) led the TSX energy sector lower, each shedding more than 3% as traders repriced near-term cash flow assumptions. Small-cap oil and gas names on the TSX-V saw even steeper declines, with several names off 5% or more by the close.
The Key Driver: Inventory Data Splits the Market
The EIA weekly petroleum status report, released at 10:30 AM ET, was the single most market-moving event of the session. The unexpected crude build triggered immediate selling in WTI futures, which cascaded into Canadian energy equities within minutes. Simultaneously, the same risk-rotation dynamic — money fleeing cyclical energy for hard-asset protection — amplified the already-strong bid in copper, gold, and silver. It was a textbook flight-to-materials session, and the TSX’s heavyweight mining exposure meant the index absorbed the energy shock and then some.

What to Watch Tomorrow, September 23
Three items deserve a spot on your radar before the open. First, Canadian retail sales data for July prints at 8:30 AM ET — a soft read could reinforce Bank of Canada rate-cut expectations and give rate-sensitive REITs and financials a lift. Second, watch the overnight China PMI flash estimate; given today’s copper surge was partly China-demand-driven, a strong read would validate the move while a miss could reverse it sharply. Finally, U.S. Federal Reserve speakers are scheduled throughout the day — any commentary that leans hawkish could pressure the loonie and add a currency tailwind for Canadian exporters. Energy traders will be watching API inventory data after the close for an early read on whether today’s EIA build was a one-week anomaly or the start of a trend.
