The latest IEA data through July places the average cost of automotive diesel at $1.94 per liter, a 14% increase from February levels. Gasoline has tracked a more temperate path, peaking at $1.99 in May before settling near $1.90. This decoupling highlights a specific tightening in distillate supply, exacerbated by systemic disruptions to global refining capacity.

Russian fuel production has hit a 24-year low following at least 30 Ukrainian drone strikes on refineries throughout July, forcing rationing across 90% of Russian regions. This supply shock has rippled outward, keeping diesel prices high despite Brent crude retreating to roughly $88 a barrel. The volatility remains tethered to the Strait of Hormuz, where ongoing negotiations between Iran and Oman regarding shipping routes have failed to provide a stable outlook. J.P. Morgan analysts anticipate Brent averaging $86 per barrel in the third quarter, though this projection relies on the absence of further regional escalation.

National fiscal policy continues to complicate the global picture. Germany experienced a double-digit price jump in July following the expiration of a fuel-tax discount, while countries like the U.K. and Sweden saw pump prices decline, proving that domestic tax structures and currency fluctuations often outweigh the influence of benchmark oil prices.
