When roughly 20 million barrels of crude and oil products transited the Strait of Hormuz daily before hostilities escalated in late February, energy analysts largely treated oil and gas as symmetrically exposed to any closure. That assumption is now colliding with arithmetic.
The headline figures look identical: the Strait accounts for approximately 20% of global oil supply, 20% of worldwide LNG shipments, and 20% of seaborne fertilizer trade. Lloyds List captured the conventional wisdom on 2 March 2026, warning that halting LNG flows “would be just as bad for gas and LNG markets as for oil.” The problem is that seaborne LNG and pipeline gas are not the same market.
Global natural gas consumption is supplied overwhelmingly by pipeline, not tanker. The 110 billion cubic metres of LNG that moved through the Strait in 2025 represented roughly 20% of seaborne LNG trade but only around 3% of total global gas supply. Losing 20% of oil supply and losing 3% of gas supply are categorically different shocks, and conflating them distorts both risk pricing and policy response.
The substitution dynamics diverge even further when examined over a medium-term horizon. Oil has no rapid demand-side substitute at scale. Electric vehicles now account for just under 4% of the global light vehicle fleet, approximately 58 million units out of roughly 1.5 billion, and because heavy transport electrification has barely begun, EVs have suppressed less than 3% of cumulative oil demand growth to date. Any pipeline bypass infrastructure capable of rerouting Gulf crude at meaningful volume would take years to permit, finance, and build.
Natural gas faces a structurally different competitive landscape. In 2025, gas-fired generation produced 6,500 TWh globally, representing 21.2% of total electricity demand. Wind and solar combined delivered 5,390 TWh, growing by 830 TWh year-on-year, a rate of 18%. Gas-fired output, by contrast, grew just 20 TWh over the same period, or 0.3%. The trajectory had already placed wind and solar on course to surpass gas in global electricity generation by the end of 2026, before any conflict premium entered the calculation.
The practical implication is striking. The 110 billion cubic metres of LNG that passed through the Strait in 2025 was sufficient to generate approximately 600 TWh of electricity. At the 2025 growth rate for wind and solar, the sector adds that volume of generation capacity in roughly nine months, even without accounting for any policy-driven acceleration. That is not a theoretical ceiling; it reflects actual hardware deployment rates already achieved in a pre-conflict environment.
The scenario that emerges from a prolonged disruption therefore splits cleanly along fuel lines. Oil markets would face a supply deficit with no credible short-cycle offset, sustaining elevated prices and compressing refining margins for an extended period. Gas and power markets, by contrast, carry a built-in structural escape valve in the form of renewable capacity that can be deployed faster than any conflict is likely to resolve. The fertilizer channel presents a separate and more intractable problem, given the limited substitution options for ammonia and urea derived from Gulf-region gas.
There are material constraints on the gas substitution thesis. Power demand continues to grow, and Ember’s analysis indicates that virtually all incremental demand in recent years has been absorbed by wind and solar rather than by additional gas or coal capacity. Absorbing a Hormuz disruption on top of baseline demand growth compresses the timeline advantage, though it does not eliminate it. Grid transmission bottlenecks in key importing regions, particularly in Europe and parts of Asia, could also delay the practical realisation of renewable substitution even where generation capacity exists.
The macroeconomic feedback loop adds another layer of uncertainty. A sustained oil price spike carries inflationary consequences that could prompt central bank tightening. Higher real interest rates would increase the cost of capital for renewable infrastructure at precisely the moment when accelerated deployment is most needed, potentially neutralising part of the structural advantage that gas substitution would otherwise enjoy. The interplay between Gulf conflict dynamics, US midterm political constraints, Federal Reserve policy, and the broader US-China trade confrontation creates a scenario space too wide for confident point forecasting.
What the numbers do support is a reassessment of how market participants price relative risk across the energy complex. The Strait of Hormuz is not a symmetric chokepoint. Its closure delivers an acute, durable supply shock to oil and a manageable, substitutable disruption to gas. That distinction will determine which markets recover in quarters and which remain stressed for years.
