Oil markets experienced extreme volatility during the Iran war, which disrupted global energy flows after the Strait of Hormuz was effectively closed following U.S.-Israeli strikes. The blockade removed a significant share of global crude oil and liquefied natural gas (LNG) supply, creating one of the largest supply shocks in modern energy history.
Benchmark Brent crude rose from around $70 per barrel before the conflict to a peak of $118 in late March, before easing back toward $83 after the announcement of a preliminary U.S.-Iran agreement. Despite the scale of disruption, prices remained far below levels seen in previous geopolitical crises, such as the aftermath of Russia’s 2022 invasion of Ukraine.
The relative stability reflected not just physical market adjustments, but also expectations around political decision-making in Washington and Tehran.
The “Trump Put” in Oil Markets
A key factor shaping trader behavior was the belief that U.S. President Donald Trump would not allow energy markets to spiral into a full-scale inflation shock.
This expectation often described as a “Trump put” suggested that policymakers would intervene, directly or indirectly, before oil prices reached levels that could trigger severe inflation or political backlash, particularly in the United States.
As a result, traders appeared reluctant to fully price in worst-case supply disruptions, even as inventories were rapidly drawn down and global supply losses mounted.
Instead, falling stockpiles were interpreted by markets as increasing pressure for a diplomatic resolution rather than signaling deeper structural stress.
How the Physical Market Held the Line
Despite geopolitical shocks, the global oil system absorbed the disruption more effectively than many analysts expected. Strategic petroleum reserves and commercial inventories were released at scale, helping offset lost barrels from Middle Eastern producers.
At the same time, demand-side adjustments played a critical role. Chinese crude imports weakened, and several Asian economies reduced consumption as prices fluctuated, preventing a sharper spike in global demand pressures.
This combination of supply flexibility and demand moderation allowed the market to “bend without breaking,” even as roughly 1.4 billion barrels of supply were effectively removed from circulation during the conflict period.
Why Prices Didn’t Spiral
Historically, closure of the Strait of Hormuz has been treated as a worst-case scenario for global energy markets. However, this episode challenged that assumption.
Several factors helped prevent a runaway price surge:
- High pre-war inventory levels provided a buffer
- Strategic stock releases softened immediate shortages
- Demand adjusted more quickly than expected
- Traders priced in a high probability of early diplomatic resolution
The result was a market that remained volatile but contained, with Brent crude failing to sustain levels above previous crisis peaks.
Post-Deal Market Dynamics
The U.S.-Iran framework agreement to reopen the Strait of Hormuz marked a turning point in sentiment, triggering a sharp easing in oil prices and expectations of normalized shipping flows.
However, the underlying physical imbalance has not fully disappeared. Global inventories were drawn down at a rapid pace during the conflict, and rebuilding them will require sustained restocking demand.
At the same time, supply recovery from Gulf producers could be faster than expected as exporters seek to regain market share. This sets up a potential mismatch between rebuilding demand and returning supply, increasing the risk of renewed volatility.
Analysis: Betting on Politics, Not Just Oil
The Iran war highlighted a deeper shift in commodity markets: pricing is increasingly influenced not only by physical supply and demand, but also by expectations about political intervention.
In this case, traders effectively bet that political limits particularly concerns about inflation and domestic fuel prices—would prevent escalation into a prolonged energy crisis. That assumption shaped pricing behavior as much as tankers, inventories, or production levels.
While that bet proved correct in the short term, it also raises questions about structural vulnerability. Physical shortages still occurred, inventories were significantly depleted, and the system is now entering a fragile rebalancing phase.
Ultimately, the episode suggests that oil markets are no longer purely driven by barrels and flows—but also by beliefs about how far political actors are willing to let markets strain before stepping in.
