US President Donald Trump announced the initiation of 'major combat operations' in Iran, citing Tehran's efforts to revive its nuclear program and develop long-range missiles. He warned of destroying Iran's missile infrastructure and navy, escalating regional tensions. The announcement could impact global oil prices and disrupt Middle East stability, affecting trade and investment flows. Markets may react with heightened volatility, particularly in energy sectors and geopolitical risk-sensitive assets. The move risks further straining US-Iran relations and could trigger retaliatory actions.
