Policy Pulse — Global Spillover — US-Canada Trade War & Commodity Shifts — 24 Aug 2026
Executive Summary
The escalating US-Canada trade war has emerged as the dominant global policy risk factor for equity markets, with 50% tariffs now in effect on approximately $20 billion of Canadian exports to the United States. Canadian Prime Minister Mark Carney has pledged "dollar-for-dollar" retaliation effective September 8, 2026, marking the most severe trade friction between the allies in decades.
Concurrently, gold has surged to 3-month highs as investors seek safe-haven assets amid geopolitical uncertainty, while crude oil prices remain elevated due to persistent Iran-Hormuz tensions despite recent de-escalation talks.
Indian Market Impact: The Sensex closed 171 points lower at 77,369, while the Nifty slipped 32 points to 24,219, as global trade uncertainty weighed on sentiment. Banking stocks declined, while metals gained on supply chain realignment expectations.

Trade volume at risk: $650+ billion annual bilateral trade

Cross-Border Analysis: Winners and Losers
Global Trade Flow Disruption
The US-Canada trade war creates third-party beneficiary opportunities for countries with neutral trade status:
Steel Sector Realignment:
- US tariffs on Canadian steel create supply gaps
- Indian steel exports (TATASTEEL, JSWSTEEL) positioned to capture Asian demand shifts
- EU steelmakers (MT, VOE.VI) may redirect Canadian-bound volumes
Agricultural Trade Diversion:
- Canadian dairy exports to US face 50% tariffs
- New Zealand (FSP.NZ), Australian dairy exporters potential beneficiaries
- Indian dairy (not a major export category) limited direct impact
Currency Impact
| Currency | Direction | Driver |
|---|---|---|
| USD/CAD | Strengthening | Trade war CAD weakness |
| USD/INR | Stable (95.65-95.70) | RBI intervention; FII inflows supportive |
| Gold (USD) | Rising ($2,550+ oz) | Safe-haven demand; 3-month highs |
Global Risk Factors
-
Retaliation Escalation: Canada's September 8 tariffs may trigger further US response, deepening the trade war.
-
USMCA Uncertainty: The trade pact's future is in question as both sides bypass agreement mechanisms.
-
Commodity Inflation: Tariff-driven cost increases may reignite inflation pressures, constraining Fed/RBI policy flexibility.
-
Iran-Hormuz Overlay: Concurrent Middle East tensions amplify safe-haven flows and energy price volatility.
Strategic Outlook
The US-Canada trade war represents a structural shift in US trade policy with lasting implications for North American supply chains. Key themes:
Near-term (1-3 months):
- Steel sector margin expansion for US/Indian producers
- Retail margin compression from input cost inflation
- Defensive rotation into IT services, utilities, and consumer staples
Medium-term (3-12 months):
- Supply chain relocation from Canada to Mexico/other jurisdictions
- Permanent trade flow realignments
- Investment uncertainty impacting North American capex
Long-term structural changes:
- US trade policy increasingly transactional and unpredictable
- Diversification of supply chains away from single-source dependencies
- Rising trade barriers as permanent feature of global commerce
