Iran Turns to Oil Disruption Strategy as War Enters Second Week
As the war between the United States and Iran enters its second week, Tehran appears to be relying on a familiar geopolitical lever: global energy markets.
After suffering heavy military losses from joint U.S. and Israeli strikes, the Islamic Republic is increasingly focused on disrupting oil flows through the Persian Gulf in an effort to pressure Washington and its allies economically. The strategy centers on creating instability around the Strait of Hormuz, one of the most strategically important maritime chokepoints in the world.
Roughly 20 percent of global oil shipments pass through the narrow waterway between Iran and the Arabian Peninsula, making it a critical artery for energy supplies headed to Europe and Asia. Any sustained disruption can ripple through global markets within days.
Shipping Through Hormuz Collapses
Although no universally recognized legal closure of the Strait has been declared, commercial shipping through the waterway has largely ground to a halt.
Vessel-tracking data shows traffic plunging sharply following the initial wave of fighting, with tanker activity falling dramatically as shipping companies pulled back amid missile attacks and military threats.
In some cases, only vessels connected to Iran have continued transiting the strait, while international tankers and cargo ships remain anchored nearby or have diverted entirely.
Several merchant ships have already been struck by projectiles during the conflict, underscoring the risk for commercial traffic.
The result has been a near-standstill in maritime trade through the Gulf, leaving hundreds of vessels stranded and forcing energy companies and shipping lines to reconsider routes and insurance coverage.
Oil Markets React With Volatility
The disruption has injected major volatility into global energy markets.
Crude prices surged sharply in the first days of the crisis, briefly climbing toward levels not seen since the early 2020s before retreating as traders attempted to gauge the conflict’s duration.
Insurance premiums for ships operating in the region have also skyrocketed, increasing shipping costs and further discouraging transit through the Strait.
Even without a formal blockade, analysts say this “functional closure” of the waterway can significantly tighten global oil supply.
Tankers carrying crude from major producers such as Saudi Arabia, Kuwait, Iraq, and the United Arab Emirates must typically pass through Hormuz to reach international markets. With those routes disrupted, regional storage facilities have begun filling rapidly and some producers have been forced to slow output.
Iran Signals Willingness to Escalate
Iranian officials have openly hinted that energy markets could become a central battlefield in the conflict.
Tehran has warned that continued U.S. and Israeli strikes could push oil prices dramatically higher, potentially above $200 per barrel if supply disruptions intensify.
Such statements reflect a longstanding Iranian strategy: leveraging asymmetric tools such as naval mines, missile attacks, and maritime harassment to threaten global energy flows.
The United States has already responded with strikes on Iranian naval assets suspected of laying mines in the waterway, destroying multiple vessels involved in maritime operations.
Washington Issues Stark Warning
President Donald Trump has warned Tehran against escalating attacks on global energy infrastructure.
In public remarks and social media statements, Trump declared that the United States would respond with overwhelming force if Iran attempts to permanently shut down oil flows through the Strait of Hormuz.
Military officials have also warned Iranian civilians to avoid ports being used for military operations, signaling that additional strikes could follow if the conflict escalates further.
A Global Problem, Not Just an American One
While the United States is now one of the world’s largest energy producers and less dependent on imported oil than in previous decades, many of its allies remain highly exposed to disruptions in Gulf energy supplies.
Countries across Europe and Asia rely heavily on crude shipments that pass through the Strait of Hormuz. Japan, for example, sources a large portion of its oil from the region.
European governments have already begun discussing the possibility of releasing emergency oil reserves if the conflict drags on and prices continue to spike.
A War of Endurance
Iran’s leadership appears to be betting that economic pressure will eventually force Washington to reconsider its military campaign.
By destabilizing the global energy market, Tehran may hope to generate political pressure on the United States from allies and trading partners who are far more vulnerable to supply disruptions.
But whether that strategy succeeds remains uncertain.
If anything, Iran’s attacks on Gulf infrastructure and shipping could also broaden the coalition arrayed against it, drawing in additional regional actors whose economies depend on uninterrupted oil exports.
For now, the Strait of Hormuz has become one of the most volatile flashpoints in the conflict—where the war’s military campaign intersects with the fragile mechanics of the global economy.
