Prolonged Iran War Could Trigger Lasting Global Gas Demand Decline

The ongoing energy shock linked to the Iran war has disrupted global oil and gas markets on an unprecedented scale.

The ongoing energy shock linked to the Iran war has disrupted global oil and gas markets on an unprecedented scale. Since the crisis began in late February, over 500 million barrels of crude and condensate have been removed from global supply, marking the largest disruption in modern energy history.

At the center of the crisis is the instability surrounding the Strait of Hormuz, a vital corridor for global energy flows. The disruption has forced countries to rapidly adjust their energy strategies in response to supply shortages and price volatility.

Warning from Global Gas Producers

Gas Exporting Countries Forum Secretary General Philip Mshelbila has warned that the current decline in natural gas demand could become permanent if the conflict continues.

Speaking at an energy conference in Paris, Mshelbila explained that governments are currently adopting short term measures to manage the crisis. However, if the conflict persists for several months, these temporary adjustments could evolve into long term structural changes.

He noted that under normal circumstances, global gas demand could recover within six months to a year if the conflict were resolved quickly. Prolonged disruption, however, risks fundamentally altering consumption patterns.

Shift Away from Gas

Countries heavily reliant on Gulf energy supplies have already begun shifting away from natural gas. In response to shortages, many are increasing coal usage and accelerating investment in renewable energy sources.

While these moves are initially reactive, they may lead to permanent reductions in gas demand if alternative energy systems become embedded in national energy strategies.

Market Uncertainty

Before the crisis, 2026 was expected to mark a turning point for global gas markets, with supply growth potentially leading to oversupply.

The current conflict has disrupted those projections. It remains unclear whether the anticipated surplus will simply be delayed or whether structural demand changes will prevent it from materializing altogether.

This uncertainty is complicating long term planning for energy producers and investors.

Missed Opportunity for Africa

Mshelbila also highlighted a missed opportunity for African gas producers. Despite having significant reserves and some excess capacity, many countries are unable to increase production to meet global demand.

Export pipelines from countries such as Algeria and Libya to Europe are not operating at full capacity, largely due to limited upstream production.

As a result, producers in North America are capturing a larger share of European and Asian markets during the crisis.

Structural Constraints

The gap between available reserves and actual production underscores a key challenge for Africa’s energy sector. While the continent holds substantial natural gas resources, infrastructure limitations and underinvestment are preventing it from fully capitalizing on current market conditions.

This has limited Africa’s ability to respond effectively to one of the most significant energy disruptions in recent history.

Analysis

The warning of potential “demand destruction” reflects a critical turning point for global gas markets. Historically, energy demand tends to recover after crises. However, the current situation differs in that it is accelerating structural shifts already underway, particularly the transition toward renewable energy.

If countries successfully replace gas with alternative energy sources during the crisis, demand may not fully rebound even after supply conditions stabilize. This would have long term implications for gas exporting countries, potentially reducing revenues and altering global energy dynamics.

At the same time, the crisis highlights the uneven distribution of opportunity within the global energy system. While some producers, particularly in North America, are able to respond quickly to changing demand, others, such as many African nations, face structural barriers that limit their participation.

The situation also underscores the interconnected nature of modern energy markets. Disruptions in one region can trigger cascading effects across multiple sectors, influencing not only supply and prices but also long term consumption patterns.

Ultimately, the trajectory of global gas demand will depend heavily on the duration of the conflict. A short lived crisis may result in temporary adjustments, while a prolonged disruption could accelerate a permanent transformation of the global energy landscape.
