Los Angeles: what changed?

Dated inputs, measured movements and the limits of each comparison.

Why prices changed

Gasoline / petrol

+0.048 USD/L (+3.025%)

The gasoline price moved from 1.581 on 2026-09-21 to 1.629 on 2026-09-28. The price change is measured, but its components cannot be reliably allocated.

Left: decrease. Right: increase. Oil is valued at the earlier FX rate; currency movement uses the later oil price. The downstream residual includes unmeasured costs and timing, not just margins. Taxes can change with prices without a policy change. This is accounting, not proof of causation.

Source headlines provide context. Their presence does not establish what caused the price movement.

Oil fell. Did the pump follow?

Gasoline / petrol

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.

Publication and revision history (2 saved versions)

Tracking begins with this feature’s first export. A new observation is a publication; a changed value for the same observation date is a revision. This is our publication history, not a complete publisher revision archive. At most 30 versions per fuel are shown; the canonical database retains all recorded versions.
