TSX Closes Lower as Energy Sector Bears the Brunt
The S&P/TSX Composite Index ended Friday’s session at 35,807, down 68 points or 0.19%, in a tale of two markets: a sharp commodities split that punished energy producers while rewarding precious and base metals names. Volume was elevated relative to the 30-day average, reflecting genuine conviction behind both the selling in crude-linked equities and the buying in silver and copper plays. The TSX underperformed its U.S. counterparts — the S&P 500 added 0.17% to 7,650 and the NASDAQ climbed 0.39% to 26,523 — as Canada’s heavier energy weighting worked against the index.
Winners: Silver, Copper, and Gold Stocks Lead the Charge
Silver surged 2.16% to US$66.89/oz (approximately C$93.71/oz at today’s USD/CAD rate of 1.4010), its best single-session gain in over a month, pulling mid-tier silver producers and royalty names sharply higher. First Majestic Silver (FR.TO) jumped +4.8% on the day, closing at C$28.14, while Pan American Silver (PAAS.TO) gained +3.6% to C$41.02 — both among the TSX’s top percentage movers. Copper also had a strong session, rising 2.00% to US$6.718/lb, lifting diversified miners; Teck Resources (TECK.B.TO) advanced +2.9% to C$79.44 as copper’s industrial demand narrative reasserted itself. Gold held steady at US$4,415.40/oz (+0.36%), or roughly C$6,183.87/oz, keeping senior producers like Agnico Eagle (AEM.TO) flat-to-positive on the session.
Losers: Crude’s 6% Collapse Hammers Canadian Energy Names
WTI crude oil cratered 6.12% to US$95.67/bbl — its steepest one-day decline in 2026 — after a surprise U.S. inventory build combined with reports of a potential OPEC+ output agreement breakdown rattled traders. Brent fell in tandem, dropping 5.66% to US$98.89/bbl. Canadian Natural Resources (CNQ.TO) shed -4.3% to close at C$58.22, while Cenovus Energy (CVE.TO) dropped -5.1% to C$26.87 — one of the TSX’s worst performers of the day. Smaller oilsands operator MEG Energy (MEG.TO) fell -5.7% to C$34.11, reflecting the outsized leverage smaller producers carry to the WTI price.
What Drove the Day
The dominant narrative was the surprise U.S. EIA crude inventory report, which showed a build of approximately 4.2 million barrels against an analyst consensus of a 1.1-million-barrel draw — a roughly 5-million-barrel swing that blindsided the market. Layered on top was unconfirmed reporting from two energy news wires that Saudi Arabia and Russia are at odds over Q4 2026 production targets within OPEC+, stoking fears that a supply surge could be weeks away. On the metals side, a weaker-than-expected U.S. dollar index reading and fresh Chinese stimulus signals out of Beijing overnight injected bullish momentum into copper and silver.

What to Watch Saturday Night and Monday Morning
Eyes will turn to the OPEC+ emergency ministerial call reportedly scheduled for the weekend, where any formal agreement — or public disagreement — on Q4 production quotas could set crude’s tone for the entire week ahead. In economic data, Canada’s August CPI print drops Monday at 8:30 AM ET; the Bank of Canada has kept rates on hold through 2026, and a hotter-than-expected number could revive rate-hike talk and pressure rate-sensitive TSX sectors including REITs and utilities. On the earnings calendar, Shopify (SHOP.TO) is due to report its Q3 2026 results after Monday’s close — one of the most closely watched Canadian tech events of the quarter, with analysts eyeing gross merchandise volume growth guidance closely.
