S&P/TSX composite down nearly 300 points as deadline for 50% tariffs from U.S. nears - BNN Bloomberg

The S&P/TSX composite index fell nearly 300 points as markets braced for an approaching U.S. deadline tied to proposed 50% tariffs. The drop reflects investor anxiety over an escalation in trade policy, with the threat of higher duties raising concerns about the cost of cross-border commerce and its ripple effects on corporate earnings.

For a resource-heavy index like the TSX, tariffs carry particular weight. Many listed companies rely on integrated supply chains and export demand, especially in energy, materials, and manufacturing. A steep tariff hike could raise input costs, squeeze margins, and reduce competitiveness, prompting investors to reassess valuations ahead of the deadline.

The key focus now is whether the deadline passes or a last-minute agreement emerges. Markets will also watch for signals on which sectors face the largest exposure and whether retaliatory measures follow. Until clarity arrives, volatility may persist as traders weigh the potential for disruption against hopes for a negotiated outcome. The development underscores how quickly trade policy can shift market sentiment.
