Türkiye's October 1 gasoline change: Is the TRY 12.48 hike official?
The official decision ends the temporary mechanism that offsets 25% of refinery-price increases through excise tax on October 1. It does not state a fixed pump-price increase; that requires new tax and price data.
Three critical developments
- From August 1 through September 30, 25% of an increase in the domestic refinery price is offset through a lower excise tax; the rest passes into the market-price channel.
- The equal-mobile mechanism ends unconditionally on October 1, 2026. That removes the 25% new offset for future refinery-price increases.
- Decision 11488 does not announce TRY 12.48 or any other fixed pump-price increase. The actual move depends on current refinery pricing, the excise-tax table, VAT and distributor-dealer pricing.
Illustrative TRY 4 refinery-price increase: what changes?
This example applies the two rules to the same TRY 4 increase in the domestic refinery price. VAT, distribution and dealer margins are excluded; it is not a pump-price forecast.
| Period | Offset through excise | Market-price channel | Simple effect for 50 liters |
|---|---|---|---|
| Through September 30 | TRY 1.00/L (25%) | TRY 3.00/L (75%) | TRY 150 |
| After October 1 | TRY 0.00/L | TRY 4.00/L | TRY 200 |
| Difference between rules | −TRY 1.00/L | +TRY 1.00/L | +TRY 50 |
Quick answer: Is a TRY 12.48 gasoline hike confirmed for October 1?
No. As of September 27, Presidential Decision 11488 does not announce a TRY 12.48-per-liter pump increase or any other fixed amount for October 1. What it does confirm is the end of the equal-mobile excise-offset mechanism on October 1, 2026. An actual pump-price change requires current refinery prices, the applicable excise amount, VAT and distributor-dealer pricing.
How does the rule work through September 30?
From August 1 through September 30, 25% of an increase in the domestic refinery price is offset through a lower excise-tax amount, while 75% remains in the market-price channel. When the refinery price falls, the official summary says excise can rise by the full amount of the decline. The mechanism does not freeze pump prices; it changes how refinery-price movements are shared between tax and market pricing.
What changes on October 1?
The decision abolishes the system on October 1 regardless of other conditions. After that date, there is no new 25% equal-mobile offset for a new refinery-price increase. This rule alone does not mean a predetermined lira amount will automatically be added at midnight; a fixed number would require separate official tax or price data.
Is a producer-price-index excise increase also due?
A separate clause in Decision 11488 prevents the statutory indexation of excise amounts for List I goods in the July–December 2026 period. The end of equal-mobile and semiannual domestic-PPI indexation should therefore not be added together as if they were the same measure. The decision skips the second-half indexation while ending the temporary offset system on October 1.
What does the TRY 4 example show?
For method only, assume a TRY 4-per-liter refinery-price increase. Through September 30, the rule offsets TRY 1 through excise and leaves TRY 3 in the market-price channel. After October 1, without a new offset, all TRY 4 remains in that channel. For 50 liters, the simple difference between the rules is TRY 50. VAT and commercial pricing are excluded, so this is not a pump forecast.
What does this mean for drivers and businesses?
Drivers should compare the same station and product on September 30 and October 1 instead of relying on one headline number. Fleets and logistics companies can stress-test budgets across several per-liter changes rather than assume one fixed hike. At monthly consumption of 10,000 liters, each TRY 1/L difference creates TRY 10,000 of cost sensitivity before VAT and other components.
Which sources should be checked?
Use the Official Gazette and Revenue Administration for tax rules, and the energy regulator's dealer-price bulletin plus distributors' current price screens for actual retail prices. A lira figure circulating in news or social media should not be treated as confirmed until one of those channels supports it. Province, district, station, product and update time can all change the price.
Method and limitations
This analysis uses the official decision and public-institution summaries accessed on September 27, 2026. The scenario uses only a TRY 4/L refinery increase and 50 liters; it does not model VAT, distributor-dealer margins, FX, international product prices or timing. The TRY 12.48 claim is excluded as data because no primary source confirmed it. This is consumer and cost information, not investment advice.
