What the sources said

Energiesteuersenkungsgesetz (Gesetz zur Aenderung des Energiesteuerrechts zur temporaeren Absenkung der Energiesteuer fuer Kraftstoffe) of 24 May 2022, BGBl. I 2022 p. 810. The Bundestag record of 19 May 2022 states the reduction ran from 1 June to 31 August 2022 and cut the energy-tax rate by 29.55 ct/litre on Benzin and by 14.04 ct/litre on Dieselkraftstoff. The same change is present in the primary tax series this project already holds: the tax rates taken from the European Commission Weekly Oil Bulletin duties and taxes file record German excise on Euro-super 95 petrol at 0.6545 EUR/litre before, 0.3590 EUR/litre effective 2022-06-01 and 0.6545 EUR/litre again effective 2022-08-31, and on diesel at 0.4704, then 0.3300, then 0.4704 EUR/litre on the same dates. The two records agree to the cent. This row is a timeline marker only; it makes no statement about how the change reached pump prices.

Choosing a fuel keeps that fuel's series and the channels shared by every fuel - the crude benchmark, FX, crude imports and Hormuz exposure. It drops only the other fuel's series.

The event window

What each series was worth from -30 to 90 days around the event date, how far that is from the same series' level at the event date, and how big that move is against the series' own normal variation.

Bulgaria, Diesel (automotive gas oil). 16 series can be drawn; 4 cannot be seen at all and are shown as labelled empty panels below.

182 published readings, 26 offsets with nothing published within one period, and 52 offsets on series we cannot see at all. Every one of them is on this page.

Is Germany: temporary energy-tax reduction on road fuels (Tankrabatt), 2022 really the reason?

The question splits into dimensions that are measured separately and never added into one number. Each row says whether we can see that dimension at all, and gives one published figure where we can.

Of the eight price-transmission channels this site reports, 4 have data in this run Calculated - a count of the rows below, not a measurement.

Methodology §11.1 publishes the thresholds the sentences below use: all eight channels present for the full comparison, at least three for the claim to be testable here at all, and 2.0 volatility units for a move to be described as outside a series' normal variation. Those are published wording choices, not statistical tests.

Pump price with taxWhat a driver actually paid.Observed
1.787 € per litre at +30 d (published 2022-06-27)+8.70% from the level at T0 = +6.09 volatility units

Physical exposure to the Strait of Hormuz and price exposure are different questions. A country with almost no direct physical exposure can still see its pump price move, because crude is priced globally - and a series that moved in this window may have moved for other reasons.

What the pump price did around this date

The decomposition page can be pinned to the weeks around the event date, so the pump move can be split into tax, input cost and the part the input cost does not account for.

Price decomposition, 2022-05-25 to 2022-07-01 →

The window is the published event date minus 7 days to plus 30 days. It is a window for looking, not a claim that the event caused what is inside it.

Actual vs crude-only: Bulgaria, diesel (automotive gas oil)

What the pre-tax price did from four weeks before to thirteen weeks after the event week, next to what it would have done had it followed only the crude input cost at the speed the stored pass-through estimate measures. The shaded difference is not explained by crude; it is not attributed to the event or to anything else.

The crude-only comparison could not be read.

  21. Over the 4 weeks after Germany: temporary energy-tax reduction on road fuels (Tankrabatt), 2022, crude costs alone would have moved Bulgaria's pre-tax diesel price by +8.0 c/L (range +5.5–+10.4); it actually moved +11.9 c/L, leaving +3.9 c/L not explained by crude. Over the same period the US diesel crack spread, a proxy for the Atlantic product market and not a European margin, widened by 11.5 $/bbl.

  22. Over the 13 weeks after Germany: temporary energy-tax reduction on road fuels (Tankrabatt), 2022, crude costs alone would have moved Bulgaria's pre-tax diesel price by +2.7 c/L (range -4.6–+10.0); it actually moved +1.7 c/L, leaving -1.0 c/L not explained by crude. Over the same period the US diesel crack spread, a proxy for the Atlantic product market and not a European margin, widened by 19.3 $/bbl.

  23. Direct physical dependence on Hormuz-linked crude for Bulgaria in 2022-06 is UNKNOWN: the source reports zero imports for this period, so there is no volume to take a share of - this is a reported zero, not missing data.

  27. Summary of what can be checked here

    Only part of the chain can be checked for Bulgaria around Germany: temporary energy-tax reduction on road fuels (Tankrabatt), 2022: 4 of the 8 series the method compares are available (crude benchmark, inventories, pre-tax pump price and pump price with tax), while refined-product benchmark, refining margin, freight rates and wholesale prices are not. Any claim that rests on the missing links cannot be tested here. This page describes what each series did around the event date. It is not a finding about cause: no causal design is published for this site, and a series that moved in the same window may have moved for other reasons.

What this does not show

  • It does not show that the event caused anything. No causal design is published for this site, and a series that moved in this window may have moved for other reasons.
  • A change in volatility units is not a significance test, and neither is a z-score. They measure different things and are not interchangeable.
  • Channels with no licensed or loaded source are shown as empty panels, not as flat lines. “We cannot see this” is not “this did not move”.
  • Nothing is interpolated. Where several offsets resolve to one published figure, that is what the publisher printed, and the change against the event date is zero because it is the same number.
