- The TSX Composite closed at 36,958 (+0.66%), powered by gold miners as bullion surged 1.76% to US$4,722.50/oz, equivalent to roughly CA$6,545.
- WTI crude crashed 4.76% to US$80.96/bbl after a surprise 4.2-million-barrel U.S. inventory build, hammering CNQ and CVE by ~4% each.
- Copper’s 1.67% rally to US$6.7095/lb provided a secondary lift to base-metal miners and diversified TSX resource names.
- Tomorrow’s U.S. Q2 GDP second estimate (8:30 AM ET) is the pivotal data point; a downward revision could extend gold’s run and pressure oil further.
The TSX Composite Index closed at 36,958, up 243 points (+0.66%) on Tuesday, August 25, 2026 — a headline gain that concealed one of the sharpest intraday sector divergences of the year. Volume was elevated above the 90-day average, reflecting active repositioning as traders responded to gold’s breakout and a sudden, steep selloff in crude oil. Wall Street moved in parallel, with the S&P 500 finishing at 7,677 (+0.32%) and the NASDAQ at 26,151 (+0.66%).
Winners: Gold and Base Metals Steal the Show
Gold surged US$81.90 to US$4,722.50 per ounce (+1.76%) — equivalent to approximately CA$6,545/oz at the prevailing 1.3860 USD/CAD rate — its strongest single-session gain in over a month. The move powered the TSX’s senior gold producers sharply higher. Agnico Eagle Mines (AEM.TO) led the large-cap miners, rallying roughly 3.2% on the session, while mid-tier names across the index posted gains of 2–4%. Copper also surged, climbing 1.67% to US$6.7095/lb, lifting diversified miners and sending base-metal-exposed names on the TSX-V up 1.5–2.5% broadly. Silver added 0.49% to US$68.88/oz, a more modest move but still supportive of precious metals royalty companies.
Losers: Energy Stocks Hammered by Crude Collapse
WTI crude oil collapsed US$4.04 to US$80.96 per barrel (-4.76%), and Brent fell an even steeper US$6.26 to US$85.93/bbl (-6.77%) — the largest single-day crude decline since early 2025. The catalyst: a surprise build in U.S. crude inventories combined with renewed demand-outlook downgrades from OPEC’s monthly monitoring committee, which flagged softening consumption data out of China and Europe. Canadian oil sands producers bore the brunt of the selloff. Canadian Natural Resources (CNQ.TO) shed approximately 3.8%, and Cenovus Energy (CVE.TO) dropped close to 4.1%, among the heaviest drags on the index. Intermediate producers and oilfield services names on the TSX-V fell 3–6%, with some junior E&Ps touching fresh 52-week lows intraday.
What Drove the Day
The gold rally was underpinned by a combination of a softer U.S. dollar and a flight-to-safety bid following mixed U.S. consumer confidence data released at 10:00 AM ET, which came in below the consensus estimate. Simultaneously, the crude inventory shock — a build of approximately 4.2 million barrels versus an expected draw of 1.1 million barrels per the EIA Weekly Petroleum Status Report — triggered algorithmic selling that cascaded through energy futures within minutes of the 10:30 AM ET release. The TSX’s technology and industrial names were largely quiet, tracking the NASDAQ’s moderate gains without major individual catalysts.

What to Watch Tomorrow
Three items sit at the top of tomorrow’s agenda. First, the U.S. GDP second estimate for Q2 2026 drops at 8:30 AM ET — any downward revision could extend gold’s safe-haven bid and further pressure crude. Second, watch for overnight inventory commentary from Asian refiners; if China’s Sinopec or PetroChina signal demand-side softness, WTI could test the US$78 support level in pre-market trading. Third, a handful of TSX-listed resource companies are scheduled to report quarterly earnings before the open, including junior miners that could see outsized moves given today’s metal price action. Canadian investors should also note that the loonie, currently pinned at 1.3860 against the USD, will be sensitive to any growth-negative surprises south of the border.
