Global oil trading firms Vitol and Trafigura are demanding significantly steeper discounts on Venezuelan crude oil, particularly for the Merey heavy crude grade. They are pushing for discounts of $18-$20 per barrel below Brent crude for September 2026, a substantial increase from the $6-$7.50 discount seen in January 2026. This reflects a deep cut compared to PDVSA's own August formula price, which implied a $14 discount. The primary driver for these demands is a near-tripling of Aframax tanker freight rates on the José-to-US Gulf Coast route, escalating from roughly $1.90 per barrel at the start of 2026 to around $5 per barrel by late September. This surge in shipping costs is attributed to the escalating US-Iran maritime conflict.

PDVSA, Venezuela's state-owned oil company, has limited leverage to resist these discount demands. Vitol and Trafigura collectively control over half of Venezuela's export volumes, and PDVSA lacks the credit to charter its own fleet or secure sufficient insurance for its tankers. The company also relies on the prompt cash payments provided by these traders. Adding to the challenge, Venezuela's crude exports remained stagnant at approximately 1.17 million barrels per day in August 2026, essentially flat compared to July. Even the dominant traders, Vitol and Trafigura, moved slightly less crude in August.

The volume ceiling is also exacerbated by dilapidated oil port terminals, which are imposing a de facto export cap despite rising crude production and high global demand. Tankers face waiting times of up to 30 days to load due to aging infrastructure, power outages, and quality issues at ports, particularly Jose, which handles about 70% of the country's exports. These delays lead to disputes over demurrage charges, crude quality, and ship contamination. PDVSA is increasingly incurring thousands of dollars in demurrage, which it often agrees to pay in crude. Analysts are divided on whether this freight shock is temporary or a more structural issue, dependent on factors like the recovery of Hormuz transit, war risk insurance premiums, and PDVSA's ability to pivot to direct-to-refinery sales amidst port constraints. Shipping costs, which traditionally were a small fraction of oil prices, are now becoming a much larger and more impactful component of the delivered cost, influencing trading decisions and potentially reducing demand for long-haul barrels.
