ECB Vice-president Luis de Guindos cautioned that President Trump's approach to Iran raises serious risks of triggering a global financial crisis. The warning signals growing concern among European policymakers about escalating tensions in the Middle East and their potential spillover effects on world markets.

De Guindos specifically highlighted Washington's volatile trade policies and reduced cooperation as factors threatening financial stability. These comments reflect mounting anxiety about how aggressive foreign policy moves could disrupt carefully balanced international economic relationships that markets depend on.

European officials have grown increasingly worried about the unpredictability of U.S. policy shifts under the Trump administration. The ECB's concerns extend beyond immediate market volatility to potential long-term disruptions in global supply chains and energy markets that could reverberate worldwide.

The warning carries significant weight given the ECB's role in monitoring systemic risks across European and global markets. Investors should brace for heightened uncertainty as geopolitical tensions intersect with ongoing trade disputes, potentially creating cascading effects through already stressed financial systems.
