Black Sea Energy Dynamics: Navigating Opportunities and Challenges in the Region

Oil Markets on Edge: Black Sea Disruptions & Diesel Price Surge Signal tight Supply

WASHINGTON D.C. – December 4, 2025 – Global oil markets are facing increasing pressure as disruptions in the black sea region, coupled with refinery outages and sanctions, drive up diesel prices and dispel any notion of an impending oil surplus. Recent events highlight the fragility of the global energy supply chain and the complex interplay between geopolitical tensions and economic realities.

Black Sea Bottlenecks & Russian Exports

Oil shipments from Russia‘s Black Sea ports have fallen short of November’s schedule by approximately 1 million tons due to severe storms and recent drone attacks impacting loading operations. while Russia continues to find avenues for export – notably through Chinese refineries – these disruptions underscore the vulnerability of global supply. Insurance rates for black Sea shipping have soared 150% following Ukrainian attacks, raising the specter of potential Russian retaliation against vessels linked to Ukraine.

Despite these challenges, the energy sector demonstrates resilience. The global market is adapting, but the situation remains precarious.

Diesel Prices Surge Amidst Refinery Issues

The Energy Information Governance (EIA) reports that global refinery margins for diesel have reached their highest point of the year, fueled by refinery outages in Russia and the Middle East, alongside newly imposed sanctions on Russian oil. This has tightened global diesel supplies, with important price increases observed in key hubs like Amsterdam-Rotterdam-Antwerp (ARA), New York Harbor, and the U.S. Gulf Coast.

The EU’s sanctions targeting Russian oil companies and refined products, building on previous measures taken in response to the invasion of Ukraine, are exacerbating the situation. Attacks on Russian refinery and export infrastructure have further constrained product exports, forcing dependent markets to seek option – and more expensive – supplies.

Adding to the pressure, the outage at Kuwait’s Al Zour refinery, ongoing maintenance in the middle East, and uncertainty surrounding Nigeria’s Dangote refinery are collectively limiting refined product availability.

U.S. Refinery Activity & Inventory Trends

Despite the global tightness, U.S.crude oil refineries are operating at a robust 94.1% of capacity, processing an average of 16.9 million barrels per day as of November 28, 2025 – a significant increase from the previous week. Gasoline and distillate fuel production have also seen healthy gains.

However, U.S. crude oil imports have decreased,averaging 6.0 million barrels per day, down 14.4% compared to the same period last year, indicating a shift towards domestic supply. Commercial crude inventories, while increasing slightly, remain 3% below the five-year average.Gasoline inventories are only 2% below average, but distillate fuel inventories are 7% below, signaling steady consumption.

Overall demand, based on total products supplied over the last four weeks, averaged a solid 20.3 million barrels per day, only marginally lower than last year.

Looking Ahead

The current market conditions clearly indicate no immediate prospect of an oil surplus. The confluence of geopolitical risks, refinery disruptions, and sanctions is creating a volatile surroundings with the potential for further price increases, notably in the diesel market. Continued monitoring of the Black Sea situation, Russian export strategies, and global refinery capacity will be crucial in navigating this evolving landscape.
