Diesel Crack Spreads Hit Records Amid Hormuz Disruptions and Global Refining Squeeze

Wall Street analysts are flagging extreme tightness in global diesel markets, with crack spreads approaching or exceeding $100 per barrel as supply disruptions from the Strait of Hormuz conflict, Russian refinery strikes, and curtailed Chinese exports converge. Jefferies' Sam Burwell noted that the 'Hormuz shock' is manifesting more in refined product cracks than in crude prices themselves, with front-month US diesel cracks recently surpassing prior highs from March 2026.

Bank of America's Francisco Blanch described a 'Diesel's Perfect Summer Storm,' highlighting impairments across three of four major refining hubs: reduced Middle East exports due to Hormuz traffic dropping to around 10 crossings daily (from 30-40 pre-escalation), record Russian disruptions, and China's export pause. Europe has turned to record US exports, drawing down tight inventories.

Citi's Anthony Yuen warned global diesel stocks are below five-year minima, echoing levels from 2022 when cracks were significantly lower. Goldman's Daan Struyven emphasized the refined products focus of the disruption. Recent Reuters reporting confirms Hormuz shipping traffic at historic lows, with just six vessels on one recent day versus pre-conflict norms.

IEA data shows massive inventory draws of over 250 million barrels in March-April 2026 tied to Hormuz restrictions, pushing stocks toward operational minimums. OilPrice.com and other outlets corroborate record refining margins driven by middle distillates like diesel amid the multi-regional squeeze.
