Iran's attacks on commercial ships are disrupting a vital lifeline for the global energy market: tanker "shuttle runs" through the Strait of Hormuz. These specialized voyages, involving repeated short trips within the Persian Gulf, are crucial for moving crude oil to larger vessels outside the strait. The shuttle tankers ferry oil from Gulf terminals to ports just beyond Hormuz, where it's transferred to ships destined for international markets.

Only a limited number of shipowners were willing to undertake these risky journeys through the strait, making these attacks particularly impactful. The repeated missile and drone strikes are targeting these essential operations, threatening the steady flow of oil to global consumers and potentially impacting energy prices. The disruption highlights the vulnerability of key maritime chokepoints and the risks faced by the shipping industry in volatile regions. Iran's actions are directly impacting crucial oil-market lifelines, endangering shuttle runs that are indispensable for the global energy market.
