TSX Closes at 36,171 as Copper Surges 2.3% and Gold Tops $4,074

TSX Closes Higher, Led by Metals and Materials

The S&P/TSX Composite Index settled at 36,171 on Tuesday, October 27, 2026 — a gain of +0.63%, or roughly 227 points — as a broad commodity tailwind propelled materials and base-metals stocks while the energy sector absorbed a punishing sell-off in crude oil. Volume was healthy, with participation above the 30-day average, suggesting institutional conviction behind the day’s advance rather than thin-market drift. South of the border, the S&P 500 added 0.60% to close at 7,723, while the NASDAQ outperformed at +1.18%, finishing at 26,478 on the back of AI-linked semiconductor names.

Winners: Copper Miners and Gold Royalties Lead the Charge

Copper was the undisputed commodity story of the session, surging +2.30% to USD $6.6575/lb (approximately CAD $9.34/lb at today’s 1.4023 exchange rate) on tightening global inventory data out of the London Metal Exchange and renewed electric-vehicle supply-chain demand signals from China. TSX-listed copper producers and diversified miners were the primary beneficiaries, with the materials sub-index posting its strongest single-session gain in several weeks. Gold added +0.89% to USD $4,074.20/oz (CAD ~$5,713/oz), anchoring precious-metals royalty companies and senior producers firmly in positive territory. Silver followed gold’s lead, rising +0.74% to USD $54.51/oz (CAD ~$76.44/oz), providing an additional lift to intermediate silver miners listed on the TSX and TSX-V.

Losers: Energy Dragged Down by a Brutal Crude Slide

WTI crude collapsed -1.79% to USD $99.94/bbl, falling back below the psychologically important $100 threshold, while Brent shed a steep -5.40% to USD $109.56/bbl — one of the sharpest single-day percentage declines for the international benchmark in 2026. The divergence between WTI and Brent narrowed sharply, pointing to specific North Sea supply disruptions unwinding and OPEC+ compliance concerns resurfacing after weekend reports of quota overproduction. Canadian integrated oil producers and oil-sands names bore the brunt of the selling, with the TSX energy sub-index underperforming the broader market by a wide margin. Pipeline operators with commodity-price exposure also retreated, though fee-based midstream names held up comparatively better on their contracted revenue structures.

Key News Drivers

Three catalysts defined the session. First, the LME copper inventory drawdown — reported before the North American open — was larger than consensus expected, triggering a short-covering rally that accelerated through the TSX morning session. Second, a weekend OPEC+ compliance report, circulated by Reuters, cited two Gulf members producing above quota, directly undermining Brent’s price floor and sparking the crude sell-off. Third, after-hours Monday earnings from two major U.S. semiconductor firms beat expectations handily, fueling the NASDAQ’s outperformance and providing a modest halo effect for Canadian tech names on the TSX.

What to Watch Wednesday, October 28

Three items top tomorrow’s watch list. Canada’s August GDP print — delayed one month in the national accounts calendar — hits at 8:30 AM ET and will be scrutinized for confirmation that the Bank of Canada’s rate path remains on hold. U.S. Q3 advance GDP drops simultaneously, and any upside surprise could strengthen the U.S. dollar against the loonie, pressuring CAD-denominated commodity prices. Finally, a cluster of TSX-listed mid-cap earnings — spanning base metals, biotech, and software — report after the close Wednesday, setting up potential overnight volatility for Thursday’s open.
