Central banks are looking beyond crude oil prices as a worsening global refining shortage pushes gasoline and diesel costs sharply higher, threatening another wave of energy-driven inflation.
Central banks are looking beyond crude oil prices as a worsening global refining shortage pushes gasoline and diesel costs sharply higher, threatening another wave of energy-driven inflation.
The key measure is the crack spread: the difference between crude oil prices and the wholesale price of refined fuels. Those margins have surged as wars in the Middle East and Ukraine disrupt refineries and fuel exports even when crude itself remains available.
The Bank of England has explicitly warned that refined-product markets may now provide a clearer picture of household energy pressure than Brent crude alone. Its July Monetary Policy Report said crack spreads remained well above pre-conflict levels because of Middle Eastern refinery outages, reduced Russian exports, Chinese export restrictions and limited spare refining capacity.
The ECB has noticed the same divergence. Minutes from its July meeting said crude prices had recently become less representative of the broader energy market because petrol and diesel crack spreads had reached new record highs.
Diesel Prices Reveal a Bigger Inflation ShockThe distinction is becoming increasingly important.
Brent crude climbed above $100 a barrel Wednesday, but European diesel futures have approached $200, while global diesel crack spreads recently reached about $108 a barrel. Industry executives expect diesel supply to remain tight through winter as damaged or restricted refining capacity removes millions of barrels of potential fuel production.
European gasoline refining margins have also exceeded $62 a barrel, approaching records established during the 2022 energy crisis.
The same pressure is visible in the United States. The EIA says elevated crude prices and unusually wide refinery margins are jointly driving higher pump prices, while U.S. diesel recently reached record levels.
That strengthens an inflation risk already visible across financial markets. Coinpaper recently tracked how rising oil prices have pressured the S&P 500 and Nasdaq, while higher energy costs have helped push UK inflation higher.
Bank of England Sees 0.4-Point Inflation HitThe Bank of England estimates higher energy prices will directly add around 0.4 percentage points to UK CPI inflation during the second half of 2026, with petrol and diesel accounting for roughly 0.3 points. Indirect effects through business costs could add further pressure.
That helps explain why markets are increasingly pricing tighter monetary policy despite signs of softer underlying inflation. Bailey said this week that rate increases are not predetermined, but markets are already attaching an inflation risk premium to higher energy prices.
The broader market consequence is familiar: persistent fuel inflation can lift bond yields and pressure growth stocks. Coinpaper's guide to rising Treasury yields shows how inflation expectations translate into higher borrowing costs, while current Fed rate-hike expectations remain highly sensitive to incoming inflation data.
The lesson for markets is increasingly clear: watching Brent alone may no longer be enough. The next major inflation signal could come from the refinery gate.
