Brent-WTI Spread: A Geopolitical Thermometer for Oil Markets

The Brent-WTI spread is an indicator of geopolitical stress in the oil market. It measures the price difference between Brent crude, the global benchmark, and West Texas Intermediate (WTI), the US benchmark.

Under normal conditions, the spread remains relatively stable at around $2-3 per barrel, reflecting transportation costs and quality differences.

However, during periods of geopolitical tensions or supply disruptions, the spread can widen dramatically as Brent receives a global risk premium.

In 2026, the spread surged to nearly $14 per barrel due to escalating geopolitical tensions and potential disruptions to global crude supply. However, when ceasefire developments emerged, the spread corrected sharply and briefly moved into negative territory near -$2.8 per barrel.
