Carnival's stock fell sharply during intraday trading, declining 5.02% as the cruise operator was caught in a broader selloff of travel-related stocks.

The decline was primarily driven by renewed geopolitical tensions after President Donald Trump declared the U.S.-Iran ceasefire deal "over," which triggered a sharp rise in oil prices. Higher crude prices increase fuel costs for cruise operators like Carnival, negatively impacting their operating expenses and profitability.

Multiple travel stocks including airlines and cruise lines retreated as investors assessed the implications of escalating Middle East tensions on energy markets and consumer travel demand. The market reaction reflects concerns that the collapse of the fragile ceasefire could lead to sustained higher fuel costs for the travel industry.
