Global diesel prices face sustained upward pressure, with Goldman Sachs analysts predicting that costs could remain high through 2027. This trend is driven by insufficient global refining capacity and the necessity of replenishing depleted petroleum stocks. Analysts suggest that maintaining higher prices may be required to manage demand, particularly as refining margins are expected to exceed $40 per barrel in 2027.

In the Black Sea, increased maritime security risks and drone attacks have significantly increased transport costs. War risk insurance premiums, which may reach 1%–2% of cargo value, could raise domestic diesel prices in Romania by 6 to 15 bani per liter. Furthermore, shipping costs for oil tankers have reached historic highs, with some supertanker charters costing significantly more than in previous years due to disruptions in the Middle East.

In Romania, the introduction of the TollRo road tax for heavy vehicles is expected to increase freight transport costs by 10% to 25%, potentially impacting consumer goods prices. Meanwhile, in the United Kingdom, Google Maps has begun integrating real-time fuel price data from the government’s FuelFinder platform to assist drivers in locating cheaper petrol and diesel amidst record costs.

Geopolitical tensions in the Middle East and disruptions in the Strait of Hormuz continue to impact the market. The International Energy Agency has noted that over 20% of Middle Eastern refining capacity has been sidelined due to regional conflicts. While some local price fluctuations have occurred, the broader outlook remains volatile due to structural supply constraints and regional instability.
