San Francisco: what changed?

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

Why prices changed

Gasoline / petrol

+0.052 USD/L (+3.228%)

The gasoline price moved from 1.604 on 2026-09-21 to 1.656 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.

Reporting around these observation dates

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 (12 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.
