What happened
The US diesel crack spread reached a record US$102.20 per barrel in August, driven by regional refining constraints and tight distillate inventories. Internationally, Singapore gasoil traded roughly US$56 per barrel above Brent crude, up from US$16 prior to Middle East conflicts. Lower global diesel supplies and high refining margins are transmitting elevated fuel replacement costs directly into international transport and industrial supply chains.
Why it matters here
Mining operations in Australia rely heavily on bulk diesel for heavy machinery, haulage, and site energy generation. Higher diesel crack spreads directly raise unit cash costs across iron ore, coal, and base metal sites, threatening earnings margins for resource companies if commodity prices stall or fail to compensate for input inflation.
What to watch
Official US EIA inventory reports and weekly Singapore gasoil margin figures to track whether refining bottleneck pressures begin to ease.
