Global Oil Market Tightens as Inventories Fall, OPEC Supply Gap Widens
Declining OECD stocks and stronger demand signal firmer crude prices in coming months
By Our Correspondent
The global oil market is showing signs of tightening as commercial oil inventories continue to decline and world oil demand outpaces supply growth, reinforcing expectations of sustained support for crude prices.
Latest oil market data indicate that global oil demand is projected to average 107.9 million barrels per day (mb/d), representing an increase of 1.7 mb/d over the previous period. In contrast, non-Declaration of Cooperation (non-DoC) liquids production is expected to rise by only 0.6 mb/d to 55.4 mb/d, while DoC natural gas liquids (NGLs) production is forecast at 8.9 mb/d, up marginally by 0.1 mb/d.
The figures leave a projected requirement for 43.5 mb/d of crude from OPEC and its allies, up by 1.0 mb/d, underscoring the growing importance of OPEC+ producers in balancing the global market.
The tightening outlook comes as commercial petroleum inventories across member countries of the Organisation for Economic Co-operation and Development (OECD) continue to decline.
According to the latest data, total OECD commercial oil stocks fell from 2.796 billion barrels in March 2026 to 2.748 billion barrels in April, representing a decline of 48.4 million barrels in one month.
The reduction was driven largely by a sharp drawdown in refined petroleum products.
Product inventories declined by 52.7 million barrels, falling from 1.452 billion barrels in March to 1.399 billion barrels in April, suggesting robust consumption and increased refinery demand.
Crude oil inventories, however, moved in the opposite direction, increasing slightly from 1.344 billion barrels to 1.348 billion barrels, a modest rise of 4.2 million barrels.
Despite the small increase in crude stocks, the steep decline in refined products pushed overall commercial inventories lower.
The inventory draw also reduced the OECD’s days of forward demand cover from 61.7 days in March to 60.1 days in April, a decline of 1.6 days, indicating that oil-consuming nations have a smaller supply buffer than in previous months.
Lower inventory cover is generally viewed as a bullish indicator because it leaves the market more vulnerable to unexpected supply disruptions, geopolitical tensions or stronger-than-expected demand growth.
Analysts say the latest supply-demand balance points to a market that is becoming increasingly dependent on OPEC+ to prevent supply shortages.
While non-OPEC producers continue to expand production, their output growth remains significantly below projected increases in global consumption, leaving OPEC members with a larger role in meeting incremental demand.
The data also suggest that refiners have continued drawing down product inventories to satisfy seasonal fuel consumption, even as crude stock levels remain relatively stable.
For major oil-exporting countries such as Nigeria, the tightening market presents an opportunity to benefit from firmer international crude prices through higher export earnings, increased foreign exchange inflows and improved government revenues.
However, industry analysts caution that Nigeria can only maximise these gains by sustaining crude oil production, reducing theft and pipeline vandalism, and ensuring that export volumes remain stable.
The latest market fundamentals also reinforce expectations that OPEC+ will continue to play a pivotal role in maintaining market stability as demand growth outpaces supply increases from producers outside the alliance.
With global oil demand continuing to rise, inventories falling and forward cover shrinking, market participants are expected to closely monitor future OPEC+ production decisions, geopolitical developments and economic growth trends, all of which are likely to determine the direction of crude oil prices in the second half of the year.
