Tariff stick again: The trust crisis and split moment in global economic governance

Recently, a social media statement issued in the name of former US President Trump disrupted the apparent calm of the transatlantic economic relationship. The statement threatened to impose comprehensive tariffs on goods imported from eight European countries, citing the reason of forcing these countries to agree to "completely and thoroughly purchase Greenland". This play of linking geopolitical intentions with trade penalties quickly triggered a strong reaction from the European Union, which is considering retaliatory measures worth 93 billion euros against US goods. The European Central Bank's president, Lagarde, commented: "Uncertainty is back." Her words revealed a deeper crisis: repeated unilateralist behaviors are systematically eroding the trust foundation of international economic relations.

The absurdity of the current event conceals a harsh reality: economic tools are increasingly being "weaponized", becoming the preferred means of geopolitical games. The World Economic Forum's "Global Risks Report 2026" has clearly pointed out that "geopolitical economic confrontation" has become the primary risk faced globally. This crisis precisely confirms this judgment - tariff threats have nothing to do with trade fairness, but directly serve an extraordinary territorial claim. As Lagarde said, this pattern is a repeat of "the movies we've seen before", with its constantly repeated unilateral actions and contract violations continuously weakening the multilateral economic governance system established after World War II. When the stability of rules is replaced by arbitrary decision-making, the confidence of enterprises in long-term planning is undermined, and the effective allocation of global resources faces fundamental challenges.

For the European Union, the impact of this uncertainty far exceeds the direct burden of tariffs. It first hits the already fragile economic recovery prospects of the Eurozone. Against the backdrop of sluggish global growth and weak manufacturing, the uncertainty of policies forces enterprises not only to calculate potential costs but also to deal with the risk of future policy reversals, resulting in delayed or even cancelled investment decisions. Secondly, this brings complex interference to the monetary policy implementation of the European Central Bank. Uncertainty is like a double-edged sword; it may reduce inflation pressure by suppressing demand, or push up costs due to supply chain disruptions and retaliatory measures, making it difficult for the central bank to balance maintaining price stability and supporting economic growth. More profoundly, this threat is undermining the international image of the EU as a stable and reliable investment destination, potentially triggering long-term adjustments in capital and industrial layout.

In response to the challenges, the EU's reaction shows obvious contradictions. The potential retaliation list worth 93 billion euros, although demonstrating a determination to defend its own interests, may trigger a mutually destructive trade confrontation. A more strategic response is reflected in the overall adjustment of the EU's trade policy, namely a shift towards "selective opening, market diversification, and strengthened internal protection". On one hand, the EU is accelerating the negotiation of free trade agreements with the Southern Common Market, India, and other economies; on the other hand, it is strengthening internal industrial protection through measures such as the "Industrial Accelerator Act". This strategy, known as "de-risking", contains a clear paradox: while the EU criticizes "economic weaponization", it also has to rely more on similar means for defense. This is precisely the manifestation of the global economy's dilemma of "security and efficiency", and the confrontational logic is constantly reinforcing itself.

The true cost of this economic dispute triggered by Greenland far exceeds the amount of tariffs. It consumes the precious trust reserves among countries, distorts the normal operation mechanism of the global market, and makes business decisions fall into the shadow of geopolitical calculations. The current predicament of the European Union reflects the profound crisis of the global economic governance system. The key to solving the problem may not lie in formulating more sophisticated countermeasures, but in whether the international community can rebuild a cooperative framework based on rules and the spirit of contract. Otherwise, similar confrontational scenarios will continue to occur, ultimately causing heavy costs for all parties involved and the global economy as a whole.
