Finland · What moved my fuel price?
Petrol and diesel prices in Finland
What a litre costs at the pump, what it costs before tax, and what moved between two weeks. Prices are published weekly; a week the publisher skipped is left as a gap.
What moved the price across this window
The change in the pump price, split into the parts that make it up. Each bar is the movement of one component between the first and last week we hold in the window.
Between 2025-09-22 and 2026-09-21 (52 weeks apart). These are the weeks we actually hold, which may differ from the dates requested.
| Component | Change (EUR/L) | Share of pump move | Type | What the value is |
|---|---|---|---|---|
| VAT | +0.19716 | 22.1% | Calculated | VAT extracted from the observed pump price at the published rate, differenced between the two endpoint weeks. |
| Excise duty | 0.00000 | 0.0% | Calculated | Excise per litre from the tax table, differenced between the two endpoint weeks. |
| Other specific taxes | 0.00000 | 0.0% | Calculated | Other specific per-litre levies from the tax table, differenced between the two endpoint weeks. |
| Pre-tax price | +0.69422 | 77.9% | Calculated | Published pre-tax price, differenced between the two endpoint weeks. Broken down further below. |
| Pump price change | +0.89138 | 100.0% | Calculated | Reported by the API as the total move. It is not the sum of the bars above; where the two differ, the difference is drawn as its own bar. |
| Component | Change (EUR/L) | Share of pump move | Type | What the value is |
|---|---|---|---|---|
| Input-cost proxy | +0.26249 | 29.4% | Calculated | Brent converted to euro per litre at the reference rate of each quote day, differenced between the two endpoint weeks. Refinery yield is not modelled. |
| UNMODELLED | +0.43173 | 48.4% | Calculated | The part of the pre-tax move the proxy does not account for. It is differenced like any other component and is never distributed across them. Nothing here says what is inside it. |
| Pre-tax price change | +0.69422 | 77.9% | Calculated | Reported by the API as the total move. It is not the sum of the bars above; where the two differ, the difference is drawn as its own bar. |

Pump change minus the four components above. Returned by the API so it can be checked rather than trusted.
Pre-tax change minus the proxy and the residual.
Plain differences between the two endpoint weeks. The residual is reported as it moved and is not distributed across the other components; nothing here says what caused any of it.
Shares are arithmetic on two stored differences. They can exceed 100% or go negative when components move against each other, and they are not an attribution of cause.
Diesel (automotive gas oil) - with tax and without tax
Both lines are published figures. The gap between them is the tax; it is broken down below.
- Pump price, with tax(official)
- Pump price, without tax(official)
- Brent (EUR per litre)(calculated)
The pre-tax price is the part that moves with crude, refining and transport costs. Excise duty is a fixed amount per litre, so it makes up a larger share when fuel is cheap.
Brent is plotted in euro per litre on the same axis as the pump prices, never on a second scale: two y-axes would invent a relationship by choosing where they line up.
What the latest week's price is made of

How long Brent takes to reach the pump
The delay at which changes in Brent line up best with changes in this country's pre-tax price, measured over the whole sample we hold.
Historically, changes in Brent have been reflected in Finland's pre-tax diesel (automotive gas oil) price with a median lag of 1 week (90% CI 1 week, r = 0.30, n = 1,084 weeks).

- A lag and a correlation, not a causal estimate (docs/PRICE_MODEL.md §3).
- bootstrap_seed is fixed, so a published interval reproduces exactly.
- Read max_correlation before lag_weeks_median: a precise lag on a weak correlation is still a weak result.
- PRICE_MODEL.md v1.0 §3. Two weekly series aligned on the retail publication week, both first-differenced (dx_t = x_t - x_{t-1}); cross-correlation r(k) = corr(d_to_t, d_from_(t-k)) for k = 0..8 weeks; k_hat = argmax_k |r(k)|. CI by stationary block bootstrap over the jointly-differenced series with geometric block lengths of mean n^(1/3) and 2000 resamples, seeded at 20260922; the reported lag is the median k_hat across resamples and the CI is the 5th/95th percentiles. Minimum sample 104 weekly observations, below which status = INSUFFICIENT_DATA and every value is NULL. A lag is never assumed, never carried over from another country and never carried over from another period.
- docs/PRICE_MODEL.md §3 step 1: Brent in EUR/L averaged over the price week. Taken from analytics.price_decomposition.input_cost_proxy_eur_per_litre, which tax_split builds as the mean of the daily quotes in the bulletin week, each converted at the ECB EUR/USD rate of its own day (assumptions A1/A5/A6). No as-of rule is used.
- Both series come from analytics.price_decomposition (same row, so the weeks cannot drift).
The correlation behind this lag is 0.30. The API supplied no caution text for it; read the correlation before the lag.
This says the two series moved together with this much delay over this sample. It does not say that one caused the other. Correlation at each lag from 0 weeks: 0.078, 0.301, 0.207, 0.021, 0.102, 0.040, 0.081, -0.018, 0.091. The bootstrap seed is fixed (20260922), so this interval reproduces exactly.
How the pump price follows crude: rises vs falls
How much of a 1 c/L move in the crude input cost had reached the pre-tax pump price after a given number of weeks, estimated separately for moves up and moves down, over two samples.
Pass-through is measured separately for weeks when the crude input cost rose and weeks when it fell, over two samples. Both are shown: the recent window and the whole history we hold are different samples and can give different answers. The figures describe how the diesel (automotive gas oil) price and the input cost moved together. They say nothing about why.
Latest three-year window
2023-09-25 to 2026-09-14
Pass-through from the crude input cost to Finland's pre-tax diesel price cannot be estimated (window 2023-09-25 to 2026-09-14): the pre-tax price and the crude input cost are not cointegrated over this window, so no long-run relationship between them is reported and no short-run model is fitted on top of one; no fallback model is substituted.
Cointegration test statistic -2.480 against a critical value of -3.376 (the statistic has to be below the critical value to clear it), on 156 weekly observations.

Latest three-year windowUnknown
Pass-through from the crude input cost to Finland's pre-tax diesel price cannot be estimated (window 2005-01-03 to 2026-09-14): the pre-tax price and the crude input cost are not cointegrated over this window, so no long-run relationship between them is reported and no short-run model is fitted on top of one; no fallback model is substituted.
Full sampleUnknown
Each sentence is rendered from a fixed template against the stored estimate. None of it is written by a language model, and none of it states a cause.
The estimate says how the two series moved together over each window. It is not a causal estimate, and a difference between the two directions is reported only where the stored test found one. Where a window has no estimate, the reason the check stopped is printed and nothing is substituted for the missing coefficients.
Actual vs crude-only
What the pre-tax price actually did across this window, next to what it would have done had it followed only the crude input cost at the speed and strength the stored pass-through estimate measures. The shaded difference is not explained by crude.
What crude alone would have done is UNKNOWN for Finland, diesel (automotive gas oil).
Neither the most recent three-year pass-through window nor the full sample has a COMPUTED estimate for this country and fuel, so there is no measured crude response to project. No substitute (such as full pass-through) is used.
No line is drawn: an unknown expected path is not a flat line at zero, and no substitute such as full pass-through is used.
- What crude costs alone would have done to Finland's pre-tax diesel price over the 51 weeks after the bulletin week of 2025-09-29 is UNKNOWN: Neither the most recent three-year pass-through window nor the full sample has a COMPUTED estimate for this country and fuel, so there is no measured crude response to project. No substitute (such as full pass-through) is used.
The expected path uses only the measured short-run response to crude. It is a description of how the two series usually move together, fitted on a sample that may include this window - not a forecast and not a causal estimate. Where no pass-through estimate exists the path is UNKNOWN and nothing is substituted.

What this page does not show
- No cause is attributed to any movement. The page shows what moved and in what order, not why.
- The residual is the part the input-cost proxy does not account for. Refinery yield, wholesale margin, freight and inventory are inside it and are not modelled separately, which is why it is labelled UNMODELLED rather than named.
- Pass-through above describes how the pre-tax price and the input cost moved together over each window. It is not a causal estimate, and a window with no estimate is a window where the test did not clear - not a finding that the relationship is absent.
