Nations increasingly use sanctions and tariffs as weapons, risking a destructive race to the bottom. A new international doctrine is needed to establish rules of engagement for economic statecraft, much like the Geneva Conventions govern military conflict, to preserve the global economy.

The tariff war was not primarily about revenue but a strategic move to create an "artificial negotiating point." By imposing tariffs, the U.S. could then offer reductions in exchange for European countries committing to American technology and supply chains over China's growing, low-cost alternatives.

Beyond the US-China rivalry, a new front is opening between Brussels and Beijing. Incidents like the French suspension of fashion retailer Shein are not isolated but symptomatic of growing European mistrust and a willingness to take action. This signals a potential fracturing of global trade blocs and increased regulatory risk for Chinese firms in the EU.

Tariffs are politically useful in a fiscal crisis because they function as a hidden consumption tax. They allow politicians to claim they're taxing foreigners and protecting the nation, while the revenue raised is insufficient to solve the debt problem and domestic consumers bear the cost.

Contrary to typical pessimism, European financial and government officials are relatively optimistic about their economic outlook. They believe they successfully navigated the Trump tariffs with minimal damage, though concerns about future trade disputes and unmet investment commitments remain.

The economic impact of tariffs is not an immediate, one-time price adjustment. Instead, Boston Fed President Collins characterizes it as a "long one-off" process where the full effect can take months or even a year to filter through the economy. This prolonged adjustment period extends uncertainty and complicates inflation forecasting.

The impending 107% tariff on Italian pasta is based on legally sound anti-dumping laws targeting a specific product. This is distinct from Trump's broader, country-specific tariffs, which were enacted via a national emergency declaration and are more likely to be struck down by the Supreme Court. This signals a key legal risk difference for global businesses.

Tariffs are creating a stagflationary effect on the economy. This is visible in PMI data, which shows muted business activity while the "prices paid" component remains high. This combination of slowing growth and rising costs acts as a significant "speed break" on the economy without stopping it entirely.

Far from being a precise tool against China, recent US tariffs act as a blunt instrument that harms America's own interests. They tax raw materials and machine tools needed for domestic production and hit allies harder than adversaries. This alienates partners, disrupts supply chains, and pushes the world towards a 'World Minus One' economic coalition excluding the US.
