What immediate impact did Trump's statement that the Iran ceasefire is 'over' have on global oil prices and stock markets?

Trump's statement caused oil prices to surge, with Brent crude climbing 5.2% to $78.02 and briefly topping $80, while global stock markets dropped — the S&P 500 fell as much as 1.1% (later trimming losses to 0.3%), the Dow dropped 576 points (1.1%), and European indices like Germany’s DAX and France’s CAC 40 each sank 2.2%.

Why are rising oil prices particularly concerning for inflation and monetary policy, according to the article?

Rising oil prices are concerning because a continuation of the war risks blocking the Strait of Hormuz — disrupting global crude delivery from the Persian Gulf — which could worsen inflation; since economists expected inflation to ease with lower oil prices, this reversal may force the Federal Reserve and other central banks to raise interest rates, slowing the economy and hurting investment prices.
