Diesel prices in the United States remain near record highs despite a recent agreement intended to boost Russian diesel exports. The deal, announced last week by former President Donald Trump and Russian Deputy Prime Minister Alexander Novak, aims to increase Russia’s diesel shipments to approximately 300,000 metric tons in October, equivalent to about 75,000 barrels per day. However, energy analysts say this volume is unlikely to significantly ease current price pressures.

Data from S&P Global Energy reveal that Russia’s diesel exports have fallen sharply over the past year. Between July and September 2025, Russia exported around 693,000 barrels of diesel per day. During the same period this year, exports dropped to approximately 140,000 barrels daily, reflecting a decline driven primarily by Ukrainian attacks on Russian refineries that have curtailed processing capacity. Russia’s refining output is estimated to be operating at about half of its historical capacity, with some experts expressing skepticism that output can be quickly restored even with the recent easing of certain U.S. sanctions.

The proposed increase to 75,000 barrels per day under the new deal remains far below previous levels and represents only a small portion of the global shortfall in diesel supplies. This deficit was exacerbated notably by a reduction of 809,000 barrels per day in diesel exports from Saudi Arabia and other Middle Eastern countries from July to September compared with the same period in 2025. The decline in Middle Eastern fuel flows is tied to ongoing hostilities involving Iran and regional security concerns around the Strait of Hormuz, a critical maritime chokepoint through which much of the world’s diesel once passed.

Analysts highlight that the principal driver of elevated diesel prices—up roughly 77 percent so far this year—is this supply shortage caused by disruptions in the Middle East and reduced Russian refinery output. While Russia has increased crude oil exports in response to limited refining capacity, such crude shipments have minimal impact on diesel availability because other countries lack sufficient spare processing capacity to convert crude into finished fuels like diesel.

Experts caution that restoring Russian refineries to pre-conflict levels could take months or years, further constraining the potential for immediate export growth. The recent partial sanction relief may facilitate some expansion of diesel exports but leaves major sanctions intact, limiting access to replacement refinery equipment and technology.

Any additional diesel from Russia entering global markets could provide some downward pressure on prices, but the scale of the increase is expected to have only a modest effect. Much of the additional diesel may be directed to countries such as Brazil, which imports significant volumes for its agricultural sector, potentially reducing its dependence on U.S. diesel exports and indirectly easing domestic price pressures.

Despite these developments, global diesel prices remain influenced by a broad set of factors, including elevated crude oil costs—hovering just above $100 per barrel—and higher shipping rates driven by geopolitical tensions, particularly the ongoing conflict with Iran. As a result, industry observers say that while the diesel export deal adds some supply, it is unlikely to substantially alter the current pricing landscape in the near term.
