The most significant trade barrier being erected by Donald Trump’s latest tariff threats is not the duties themselves, but the dense fog of economic uncertainty they create. For businesses across Europe, the inability to predict the rules of trade from one month to the next is a paralyzing force that stifles growth, delays investment, and makes long-term planning impossible.
This “economic fog of war” is evident in the statements from companies and industry groups. A spokesperson for Ikea captured the mood perfectly, stating the company is “closely monitoring the evolving situation.” This is the language of a business in a defensive crouch, forced to react rather than proactively plan. The German VDA’s warning that tariffs “burden investment” speaks to the same issue: capital is frozen when the future is this murky.
The UK’s pharmaceutical sector is trapped in the thickest part of this fog. It is operating under a cloud of complete uncertainty, not knowing if its largest export market will still be viable after October 1st. This makes it impossible to make decisions about hiring, research, or production levels.
This climate of unpredictability is a direct result of a policy approach that relies on sudden announcements, contradictory promises (like the “preferential treatment” offered to the UK), and the use of brinkmanship. It keeps allies and competitors alike permanently off-balance, but it also inflicts significant collateral damage on the global economy.
Ultimately, this uncertainty may be a more potent economic weapon than the tariffs themselves. While a tariff is a quantifiable cost that can be factored into a business plan, deep uncertainty is a corrosive force that can grind economic activity to a halt. In this trade war, the fog is as dangerous as the bullets.
