25.08.2026 - New Trade War

Canada strikes back. Just days after US–Canada trade negotiations collapsed, tariffs are back in focus.

Today, Canada announced retaliatory tariffs on CAD 27.6 billion, roughly USD 20 billion, of US goods, matching the latest US tariffs dollar-for-dollar. Washington's new 50% tariffs on the same value of Canadian goods came into effect on August 22.

Canada's counter-tariffs will take effect on September 8, with duties ranging from 15% to 50% across hundreds of products. The measures target sectors including steel, dairy, appliances, agricultural equipment, pulp and paper, and electronics.
At the same time, Ottawa unveiled a CAD 7.5 billion support package for Canadian businesses and workers affected by the escalating trade conflict.

The tit-for-tat escalation marks another significant deterioration in the relationship between two of the world's closest trading partners.

Only days ago, both sides still appeared relatively close to reaching an agreement. Instead, negotiations collapsed and have now been replaced by 50% tariffs and direct retaliation.

Markets:

• Equities: So far, the market reaction remains surprisingly muted, with no major moves in either US or Canadian equities.
  

My View: Are tariffs coming back as a major market topic?

Investors had almost forgotten about the tariff story. Attention shifted toward the Middle East, inflation, rising global bond yields and, increasingly, the US debt situation.

However, current escalation between Canada and the US is an important reminder that the trade wars are far from over.

The first question is why Washington is again willing to escalate tariff pressure against one of its most important trading partners.
One possible explanation increasingly worth considering is the US fiscal situation.
As highlighted repeatedly in recent Market Insights, the bond market is starting to demand greater fiscal discipline from Washington. US debt has moved above USD 40 trillion, refinancing costs are rising rapidly, and investors are increasingly questioning the sustainability of the current fiscal trajectory.

Against this backdrop, tariffs serve more than one purpose. They are a negotiating instrument, but they also generate additional government revenue.
This does not mean that reducing the debt burden is the sole or even primary reason behind the latest tariffs. The Trump administration has consistently used tariffs to pursue broader trade, industrial and political objectives. But with fiscal pressure increasing, the revenue component should not be underestimated.
Washington urgently needs additional sources of income while simultaneously trying to avoid politically difficult spending cuts or tax increases.

The second interesting development is Canada's willingness to retaliate aggressively.
Until now, most countries confronted with US tariff threats have ultimately prioritized negotiations and concessions over a major escalation. China has been the clearest exception.

Canada is now taking a noticeably tougher approach. It raises an interesting broader question: Are governments increasingly concluding that demonstrating strength is more effective than immediately making concessions to Washington?

Recent geopolitical confrontations, including the US conflict with Iran, may reinforce the perception that aggressively pushing back can create negotiating leverage. Whether this strategy will work for Canada remains to be seen, but Ottawa is clearly signaling that it is not willing to simply accept Washington's terms.

For financial markets, today's announcement may still look like a side story. But investors should not ignore the signal. If the US increasingly turns toward tariffs as both an economic policy instrument and a source of government revenue, Canada may not be the last country facing renewed pressure.
And if more governments respond with meaningful retaliatory tariffs, the consequences could quickly become more relevant for global trade, corporate margins, supply chains and, importantly, inflation.

Tariffs are back on the radar — and today's escalation shows that this topic is far from resolved.
