Oil-to-pump tracker

United Kingdom: gasoline example

Does local crude movement line up more closely with pump changes in the same week or later? This compares weekly changes at delays of 0 to 8 weeks over up to five years, using the latest continuous publisher and currency segment.

At least 52 compatible weekly changes are needed; each correlation needs 12 pairs and variation in both series. Joins allow one day of reporting-date variation. Missing weeks are not filled. Each later pump change covers one week, not a cumulative response. Correlation does not measure a causal pass-through delay or prove that rises travel faster than falls. No forecast is implied. Benchmark and FX inputs are no more than 10 days old and never from a future date.
