Oil prices and financial markets swing after Trump's Iran announcement

Financial markets reacted sharply to an announcement by President Donald Trump regarding Iran. Oil prices jumped above $100 per barrel, natural gas prices rose, and U.S. borrowing costs saw a significant increase, while stock markets opened lower.
