Which countries control most of the oil?
Global oil reserves are highly concentrated in a small number of regions rather than being evenly distributed. Around 1.7 trillion barrels of proven oil reserves exist worldwide, and nearly half of this oil is located in the Middle East, making it the most dominant region globally.
A handful of countries, led by Venezuela, Saudi Arabia, and Iran control a significant portion of the world’s supply, with the top 10 countries alone holding over 80% of global reserves.
Outside the Middle East, major reserves are found in North America, South America, Africa, and parts of Eurasia, but these are much smaller in comparison.
Top 10 Countries by Oil Reserves
- Venezuela – 17.17%
- Saudi Arabia – 15.14%
- Iran – 11.82%
- Canada – 9.24%
- Iraq – 8.22%
- United Arab Emirates – 6.40%
- Kuwait – 5.75%
- United States – 4.74%
- Russia – 4.53%
- Libya – 2.74%
How does this affect South Africa & Africa?
Global oil reserves are concentrated outside Africa, which makes countries like South Africa heavily dependent on imports and exposed to global price fluctuations. As a result, fuel and lubricant costs are largely influenced by major producers such as Saudi Arabia and Russia, as well as exchange rate movements between the Rand and the US dollar, which often amplifies local price changes.
While Africa does produce oil in countries like Nigeria, Libya, Algeria, and Angola, limited refining capacity means many nations still rely on imported refined products. This leaves much of the continent as a net price taker in the global oil market rather than a price setter.
For South Africa, this translates directly into higher and more volatile operating costs in key industries such as mining, construction, and transport, where both fuel and lubricants are essential. It also highlights the importance of efficiency and effective equipment maintenance, since reducing waste and improving lubrication practices can help offset some of the impact of global oil price movements.
What it means for the industry?
As we have already seen, fuel and lubricant costs have increased significantly and continue to rise, placing additional pressure on companies across the industry. These escalating costs are forcing organisations to re-evaluate their operating models and look for more sustainable and cost-effective alternatives.
This raises an important question: will we see an accelerated shift toward electric vehicles (EVs) as companies look to reduce fuel dependency and operating costs, or will the industry instead see greater adoption of bio-based lubricants due to the rising costs?
Both paths present viable opportunities, but each comes with its own challenges in terms of cost, performance, and infrastructure readiness. It will be interesting to see which direction gains the most momentum in the coming years.
Please share your thoughts in the comments on what you believe the next major shift in the industry will be.
