Global Maritime War: Strait of Hormuz and the Price of Oil at 2026

The global maritime war is intensifying from the Strait of Hormuz to the North Sea, and more than the price of oil is at stake. The US military campaign to protect merchant shipping from Iranian attacks by asserting direct maritime control in the Strait of Hormuz echoes historical patterns of power projection. Almost exactly 200 years ago, a powerful US naval squadron led by Commodore John Rodgers was sent to the Mediterranean to defend American ships from Greek corsairs and pirates. That mission, like today's, prioritized US trade and business interests over broader ideals of liberty.

Today, the conflict is centered on the Strait of Hormuz, a chokepoint for about 20% of the world's oil supply. Iran has threatened to disrupt passage in response to increasing sanctions, while the US vows to keep the waterway open. The stakes extend beyond oil prices to the entire framework of international maritime law and the rules-based order.

The Historical Precedent of Maritime Control

In the 1820s, the US Navy did not assist Greece's struggle for independence from the Ottoman empire. Its sole purpose was to defend trade routes and markets. Similarly, Donald Trump's recent confrontations with Iran have boiled down to protecting economic interests. After abandoning calls for regime change in Tehran, the US now focuses on ensuring free passage through international waters.

The principle of mare liberum (the free sea), developed by Dutch jurist Hugo Grotius, has underpinned global trade for centuries. Although the US has not ratified the 1982 UN Convention on the Law of the Sea, it historically upheld freedom of navigation. However, recent actions by the Trump administration have created confusion. Secretary of State Marco Rubio stated in June that 'no country is allowed to charge tolls or fees on an international waterway,' yet Trump later suggested the US itself might impose such tolls.

The Fragile Peace Deal and Double Standards

Last month's memorandum of understanding with Iran accepts that Iran, alongside Oman, has a right to monetize transit through the Strait of Hormuz. This contradicts earlier US positions and reflects a wider breakdown in the 'free sea' consensus. Despite the resumption of US attacks and increasingly harsh threats from Trump, the MOU remains the only basis for a future peace deal. This two-faced stance is hastening the degradation of the international rules-based order.

Trump believes that nation states (or at least the US) have an absolute right to act unilaterally. This approach undermines the multilateral agreements that have governed global shipping for generations. The result is a patchwork of confrontations from the Strait of Hormuz to the North Sea, where Russia has also challenged maritime rights.

Key Players and Their Stances

Broader Implications for Global Trade

The standoff in the Strait of Hormuz is not an isolated event. The North Sea has seen increased tensions due to Russian naval activities and shadow fleet operations that avoid sanctions. Together, these hotspots signal a global maritime war that threatens supply chains, insurance costs, and energy security. The price of oil has already spiked, but the long-term damage to the legal framework for international commerce may be more severe.

Businesses and investors must monitor these developments closely. Any disruption to the Strait of Hormuz could raise oil prices by 20-30% in the short term, while a breakdown of maritime law would encourage piracy, illegal tolls, and conflict escalation.

Key Takeaways

• The US military campaign in the Strait of Hormuz repeats historical patterns of prioritizing trade over ideals.
• Trump's inconsistent policies on tolls and international law undermine global maritime stability.
• The breakdown of the 'free sea' consensus threatens oil prices and the entire rules-based trading system.
• From the Strait of Hormuz to the North Sea, maritime conflicts are becoming more frequent and dangerous.
• Diplomatic solutions, such as last month's MOU, remain fragile but essential.
