Markets around the world tumbled after President Donald Trump announced new import tariffs on goods from eight European countries, escalating fears of a transatlantic trade conflict. US stock futures dropped sharply, with technology and industrial shares leading declines, while European and Asian markets also posted losses. The tariff threat, which targets countries including Denmark, Norway, Sweden, France, Germany, the Netherlands, Finland, and Britain, was widely condemned by European leaders, who are considering retaliatory measures. The standoff is expected to overshadow global economic discussions at the World Economic Forum, as investors seek safe havens like gold and the Swiss franc, and oil prices slip amid concerns over global growth and rising geopolitical tensions.
