I noticed an interesting pattern: when talking about global politics and economics, the most obvious factor is often overlooked — oil. Oil reserves are distributed extremely unevenly across countries, and this creates geopolitical imbalances that we observe every day.

Let's take Venezuela as an example. The country owns the largest proven oil reserves in the world — about 303 billion barrels, most of which are concentrated in the Orinoco region. It sounds like a huge wealth, but here’s the paradox: with such reserves, Venezuela today produces less than 1 million barrels per day. Political instability, sanctions, and corruption have almost paralyzed its oil industry. Plus, most Venezuelan oil is extra-heavy, which is more expensive and difficult to refine. It turns out that having resources does not guarantee influence on the market.

A completely different story is Saudi Arabia. With reserves of 267 billion barrels, it controls some of the most accessible and cheapest oil resources on the planet. This gives Riyadh disproportionate influence on global prices. Saudi Arabia plays the role of a “regulating producer” within OPEC+, adjusting production volumes to stabilize the market. That’s where real power lies.

Iran ranks third with 209 billion barrels, but international sanctions seriously limit its export capabilities. Nevertheless, in 2025, Iran managed to reach its highest export level in seven years — showing that even under global restrictions, the country found ways to maintain supplies.

Canada with 163 billion barrels ranks fourth, but most of its reserves are in Alberta’s oil sands. These are technically proven reserves, but extraction requires huge investments and energy. Canada remains a major exporter, especially to the US.

Iraq with 145 billion barrels is another key player, although internal conflicts and political instability slow down its potential. The UAE and Kuwait each hold over 100 billion barrels.

It’s useful to understand that the Middle East controls about 48% of the world’s oil reserves. Venezuela, Saudi Arabia, Iran, Canada, and Iraq together hold roughly half of the known global oil reserves. These are not just economic figures — they are geopolitical weight.

Russia with 80 billion barrels remains a key exporter, although sanctions affect its production. The US ranks tenth in reserves, but thanks to shale oil extraction technologies, it remains one of the largest producers.

The most interesting aspect of this picture is how oil reserves by country determine not only the economy but also geopolitical alliances, conflicts, and international relations. Oil and politics in these regions are inseparable.
