U.S. Secretary of State Marco Rubio Warns Iran is Using the Strait of Hormuz as an 'Economic Nuclear Weapon'
U.S. Secretary of State Marco Rubio accused Iran of using the Strait of Hormuz as an 'economic nuclear weapon,' claiming that Iran is boasting about its ability to hold 20% of the world's energy supply hostage.
Rubio emphasized that Iran's threats to block the strait constitute strategic blackmail against global energy, noting that Iran has repeatedly stated its capability to close the strait.
In market terms, global energy buyers are accelerating the securing of alternative supplies and futures hedging, with funds shifting from Iranian oil-related assets to Saudi Arabia, Iraq, U.S. shale oil, and LNG exporters. The volatility in oil prices benefits energy traders and non-Iranian oil-producing countries, while Asian importing countries reliant on the Hormuz route and Iran's export chain are under pressure.

Marco Rubio, as Secretary of State under the Trump administration, has long held a hardline stance against Iran, continuing the sanctions and energy decoupling policies he promoted during his time as a senator. This statement directly reflects the current U.S.-Iran tensions and public concerns over the safety of shipping in the Strait of Hormuz.
In terms of capital flows, the U.S. and its allies are mobilizing strategic oil reserves and LNG export capacity, shifting resources from Iranian oil procurement to Saudi production agreements and U.S. energy infrastructure. The strategic goal is to weaken Iran's leverage over global oil transport routes through supply diversification, while encouraging European and Asian buyers to sign long-term contracts for non-Iranian sources to reduce disruption risks.
Similar cases include the short-term spike in oil prices after Iran seized tankers in 2019 and Europe's rapid shift to U.S. LNG as a substitute for Russian pipeline gas following the Russia-Ukraine conflict in 2022. The current energy landscape in the Middle East is accelerating the transition from reliance on Iranian routes to a restructured global supply chain.
Essentially, this is a restructuring of the supply chain: the critical energy chokepoint is being weaponized, with the mechanism being that the Strait of Hormuz, which handles about 20% of global oil transport, has a physical monopoly. Geopolitical conflicts amplify the supply disruption premium, leading to a concentration of pricing power from Iranian strategic threats to diversified producers, LNG exporters, and hedge funds, while accelerating the global energy trade's transition from traditional shipping to multi-source and technological alternatives.
