The conflict involving Iran has been reported to have caused one of the most severe disruptions to global oil supply in recent decades. According to estimates cited by analysts and the news agency Reuters, the world has lost more than 50 billion US dollars’ worth of crude oil production over a period of 50 days as a result of the conflict.
The Reuters calculation is based on the volume of crude oil that was not produced during this timeframe due to the disruption linked to the war. It does not refer to oil physically destroyed or permanently removed from reserves, but rather to output that would normally have been expected under standard production conditions. The total value of this unproduced crude oil is assessed at over 50 billion US dollars.
Additional data from the market analysis firm Kpler supports the scale of the disruption. It reports that global supplies of crude oil and condensates fell by more than 500 million barrels after the onset of the crisis. Condensates, which are light hydrocarbon liquids often produced alongside natural gas, form part of the broader liquid hydrocarbons supply tracked in global energy markets. The combined reduction reflects oil and related liquids that did not reach the international market during the period in question.
The timeline of the disruption is reported to have begun on 28 February, when the United States and Israel carried out coordinated strikes on Iran. This marked the start of the period over which the supply losses have been calculated. A ceasefire was subsequently agreed, lasting 14 days, although reports indicate that its longer-term stability remains uncertain as the arrangement approaches its expiry.
Reuters has noted that the scale of this disruption is without precedent in modern energy market history. While global oil markets have experienced shocks in the past due to geopolitical tensions, production outages, or sanctions, the reported reduction over such a short period is considered particularly significant in terms of volume and value.
Analysts referenced in the reporting suggest that the effects of this disruption may not be confined to the initial 50-day period. Instead, the consequences could continue to influence supply chains, pricing structures, and market stability in the months ahead, depending on how the geopolitical situation evolves and how quickly production and transport networks recover.
Reported impact summary
| Category | Figure |
|---|---|
| Duration of disruption | 50 days |
| Estimated value of lost crude oil | Over US$50 billion |
| Reduction in global crude oil and condensates supply | Over 500 million barrels |
| Start of reported conflict period | 28 February |
| Ceasefire duration | 14 days |
Overall, the reported figures highlight the extent to which geopolitical conflict can affect global energy flows. The disruption reflects both reduced production and wider impacts on supply chains, underscoring the sensitivity of global oil markets to instability in key producing regions.
