ECB's Lagarde warns of inflation danger and signals readiness to act.

The European Central Bank (ECB) President, Christine Lagarde, has warned of the dangers of "tit-for-tat" inflation, which could arise from a global trade war. She urged countries to avoid imposing tariffs on each other, as this could lead to a spiral of rising prices and reduced economic growth. Lagarde also called for greater cooperation between nations to address the challenges facing the global economy.
