Understanding UK PPI output index: coke and refined petroleum
Refinery gate prices for petroleum fuels, heating oils, and manufactured coke products processed within the United Kingdom are recorded by this output index. The series measures transaction values charged by domestic petroleum refineries, while excluding crude oil extraction at the wellhead and retail fuel station forecourt prices. Compared with upstream crude extraction, this index reflects refining margins, cracking plant utilisation rates, and complex processing costs applied to crude hydrocarbon inputs.
Reading these monthly figures requires accounting for extreme volatility driven by international crude oil benchmarks, refinery maintenance schedules, and foreign exchange fluctuations. Provisional monthly estimates are routinely revised as refineries reconcile production and pricing accounts. Twelve-month percentage changes provide a clearer analytical picture by smoothing out erratic monthly swings caused by sudden geopolitical events or temporary refinery outages. When comparing this index with consumer transport fuel prices, analysts must account for fixed fuel duties, VAT, and retail station operating margins that create a wide gap between refinery gate values and pump prices.
Frequently Asked Questions: Q: Does this index track crude oil extraction prices? A: No, crude extraction is monitored under a separate upstream mining category, whereas this series covers processed petroleum products from refineries. Q: Why does this index exhibit high monthly volatility? A: Close linkage to global crude oil markets and international fuel trading causes rapid and substantial monthly price movements. Q: Are retail fuel station markups included in these figures? A: No, prices are recorded at the refinery gate, excluding distribution logistics, retail margins, and government fuel duties.
