Crude oil continues to shape the global economy and influence the balance of power among nations. Countries endowed with vast petroleum reserves often wield significant geopolitical leverage, and tensions over energy security have repeatedly spilled into diplomatic and military confrontations.

The ongoing United States-Israel-Iran conflict have once again pushed oil markets into uncertainty, underlining how deeply energy and geopolitics remain intertwined.

1. Venezuela

At the top of the global reserves list stands Venezuela, with an estimated 303.22 billion barrels of crude oil. Despite its economic turmoil, the South American nation possesses the world’s largest proven reserves. Over the years, it has maintained close strategic ties with Russia, which has extended military equipment, investment and diplomatic backing. The US, meanwhile, has sought to increase pressure through sanctions and political manoeuvring, keeping Venezuela at the centre of a broader energy power struggle.

2. Saudi Arabia

Second on the list is Saudi Arabia, holding around 267.2 billion barrels. Long regarded as America’s strongest ally in West Asia, the kingdom plays a pivotal role in stabilising or tightening global oil supplies. Much of its crude exports flow to Western markets, reinforcing its longstanding strategic partnership with the United States.

3. Iran

Iran ranks among the top three, with reserves estimated between 157 and 158 billion barrels. Iran-US relations have been adversarial for decades, often revolving around sanctions and oil exports. In recent years, Iran has strengthened its engagement with Russia and China, positioning energy cooperation as a counterweight to Western pressure.

4. Canada

Canada, with roughly 170 billion barrels, also figures prominently. A member of NATO and a close neighbour of the United States, Canada exports the bulk of its crude southward, making energy trade a cornerstone of bilateral ties.

5. Iraq

Iraq holds about 145.02 billion barrels. Since the 2003 invasion, American influence has been significant, though recent years have seen growing involvement from both Russia and Iran in Iraq’s energy and political landscape, reflecting a complex balance of interests.

6. United Arab Emirates (UAE)

The United Arab Emirates possesses around 113 billion barrels. While it remains a key American strategic partner, the UAE has simultaneously expanded energy cooperation with Russia and China, signalling a more diversified foreign policy approach.

7. Kuwait

Kuwait, with approximately 100 billion barrels, continues to align closely with the US. Since the Gulf War, the United States has played a central role in Kuwait’s security architecture, which in turn shapes its oil policy and export strategies.

8. Russia

Russia, with an estimated 80 billion barrels in reserves, remains a global energy heavyweight. Beyond reserves, it is one of the world’s largest oil exporters and has frequently leveraged energy supplies as a geopolitical instrument, particularly in its rivalry with Western powers.

9. United States

The United States itself holds between 35 and 50 billion barrels of proven reserves. States such as Texas, North Dakota and New Mexico anchor the country’s production capacity. In recent years, America has emerged as the world’s largest oil producer, reshaping global supply dynamics even though its proven reserves are smaller than several Middle Eastern and Latin American producers.

10. Libya

Rounding out the top ten is Libya, with 48.36 billion barrels. Ongoing civil conflict has divided the nation, with rival factions drawing support from competing international backers, turning oil infrastructure into both an asset and a flashpoint.

Oil today is far more than a commodity powering vehicles and industries; it is a strategic asset that shapes alliances and rivalries. Venezuela and Iran lean towards Russia, while Saudi Arabia, the UAE, Kuwait and Canada maintain strong alignment with the United States.

Iraq and Libya illustrate how influence can be contested, with multiple powers vying for strategic footholds. Decades into their rivalry, the US and Russia continue to view energy as a critical lever of global power, a reminder that the politics of oil remain as combustible as the fuel itself.
