US leads global output in 2025
Global oil production continues to be dominated by a small group of countries, with the United States maintaining its position as the world’s largest producer in 2025.
According to the latest data, the US produced 13.58 million barrels per day, significantly ahead of Russia with 9.87 million and Saudi Arabia with 9.51 million barrels per day. Together, these three countries accounted for 39% of global oil production.
Sharp drop beyond top producers
Beyond the top three, global oil production declines notably. Canada ranked fourth with 4.94 million barrels per day, followed by Iraq (4.39 million), China (4.34 million), and Iran (4.19 million), which accounted for roughly 5% of global output.
The figures highlight a highly concentrated market structure, where a limited number of countries drive the bulk of supply.
Middle East remains key oil hub
Despite the US leading individually, the Middle East remains the most influential regional bloc in global oil production.
Countries including Saudi Arabia, Iraq, Iran, the United Arab Emirates, and Kuwait collectively produced around 32% of the world’s crude oil in 2025, underscoring the region’s strategic importance.
Recent geopolitical tensions, particularly the war involving Iran in 2026, have disrupted production and trade flows, with key energy infrastructure damaged or taken offline.
Uncertainty over supply routes
Even if tensions ease quickly, restoring production capacity will take time and investment, while uncertainty remains high around critical shipping routes such as the Strait of Hormuz.
These risks continue to weigh on global oil production and market stability.
Market shaped by limited players
The concentration of global oil production becomes even clearer when looking at the top ten producers, which together accounted for 72.2% of total output.
Other contributors, such as Kazakhstan, Norway, Mexico, Nigeria, Libya, and Guyana, play important roles but remain far behind the leading producers.
The result is a global oil market where a small number of countries continue to shape supply trends and influence price dynamics.
