Carnival's stock fell 5.04% in pre-market trading, extending losses from the previous session as the cruise operator faces headwinds from escalating geopolitical tensions and surging fuel prices.

The decline follows coordinated U.S. and Israeli air strikes on Iran over the weekend, which roiled global markets and sent oil prices sharply higher. The conflict has effectively closed the key Strait of Hormuz shipping route, disrupting travel and pushing up costs for marine and jet fuel—a significant expense for cruise lines.

Beyond the immediate geopolitical concerns, the broader cruise industry is also facing scrutiny following a competitor's disappointing earnings report and downbeat outlook, raising questions about consumer demand. The combination of these factors has made travel stocks particularly vulnerable in the current market environment.
