Recently, I’ve been paying attention to an interesting phenomenon—global energy politics are being reshaped, and the root of it all lies in the distribution of oil reserves across countries.

I noticed that although Venezuela has the world’s largest oil reserves—more than 300 billion barrels—these resources have become a “curse” rather than wealth for the country. Frequent intervention in Venezuela’s affairs through U.S. policies, international sanctions, and domestic political turmoil have pushed the country’s oil production down to fewer than 1 million barrels per day. Ironically, with one-fifth of the world’s oil reserves, it still can’t become a real energy superpower.

By contrast, Saudi Arabia’s approach is completely different. It has about 267 billion barrels in reserves, but the key is that these oil fields are easy to extract and relatively inexpensive to operate—giving Saudi Arabia absolute say in the global energy market. As a core member of OPEC+, Saudi Arabia plays the role of a “stabilizer,” stabilizing oil prices by adjusting production. This is the true kind of energy influence.

Iran’s situation is even more complicated. With reserves of 209 billion barrels—ranking third—international sanctions have long restricted Iran’s oil exports. Interestingly, in 2025 Iran’s oil exports actually hit a seven-year high, which suggests Iran is looking for new sales channels to bypass sanctions. Through underground smuggling and alternative buyers, Iran survives in the gaps.

Canada and Iraq also have substantial reserves (about 163 billion and 145 billion barrels, respectively), but they face different predicaments. Canada’s oil sands are costly to develop and energy-intensive, and it is worried that a recovery in Venezuela could steal market share from the United States. Iraq, meanwhile, is plagued by internal conflicts and behind-the-times infrastructure. Although it is an important supplier to Asia and Europe, its production capacity has far from been fully unleashed.

Looking at the distribution of oil reserves worldwide, the Middle East still controls about 48% of global reserves, and this level of concentration is itself a geopolitical time bomb. Even though Russia’s reserves are relatively smaller (800+ billion barrels), its role as an essential Eurasian energy hub is irreplaceable. The United States may rank lower in reserves, but through the shale oil technology revolution, it has become one of the world’s largest producers.

The logic behind it all is clear: having more reserves doesn’t necessarily mean having greater influence. What truly determines the global energy landscape is geopolitics, technological capability, market access, and international relations. Venezuela is the best counterexample.
