European Central Bank (ECB) website published a speech by Vujčić, who stated that Europe should enhance resilience through deeper integration, stronger risk sharing, and diversified supply chains, rather than retreating into isolation. He noted that differences in national rules, standards, and procedures create barriers akin to "internal tariffs"; the ECB estimates these tariff equivalents to be around 67% for goods and 95% for services, though this is an upper bound estimate. He advocated for reducing internal trade barriers for goods and services and improving the single market.
