The escalation threatens global oil supply as the Strait of Hormuz handles about one-fifth of seaborne oil. Reduced traffic and potential closure could lead to higher oil prices and increased volatility in energy markets.
Renewed military strikes between the United States and Iran have caused a sharp decline in commercial vessel traffic through the Strait of Hormuz, a critical chokepoint for global oil shipments. On July 13, 2026, tanker traffic fell to its lowest level in two months, with only six vessels transiting the strait, according to Kpler data. U.S. forces conducted a wave of precision strikes against Iranian targets, while Iran's Revolutionary Guards claimed to have stopped two ships by disabling their systems. U.S. President Donald Trump stated the strait remains open, contradicting Iran's earlier closure declaration. Ship-to-ship transfers off Oman have increased as vessels avoid the strait. The conflict has raised concerns about global oil supply, with shipbroker Gibson warning of tighter supply and higher prices if the strait is prolonged closed. No LNG tankers were observed entering the strait over the weekend.
