Sharp Decline in Brent Crude Prices Leads to Gasoline Discount in Turkey

Recent developments in global energy markets have positively impacted fuel pump prices in Turkey. Following a notable decline in Brent crude oil prices, a discount of approximately 99 kuruş per liter on gasoline took effect from June 19, 2026. This reduction allows vehicle owners to start the new day with lower prices, while the volatility in fuel prices continues to be closely monitored by markets.

In international markets, Brent crude oil fell to around $79 per barrel on June 18, 2026, reaching its lowest level in 3.5 months and experiencing a sharp weekly drop of approximately 10%. The primary catalyst for this decline was a temporary peace agreement reached between the United States and Iran. Following the agreement, improved shipping conditions in the Strait of Hormuz and the lifting of restrictions on Iranian ports by the US Central Command significantly eased supply concerns in the markets. Furthermore, Kuwait's announcement to increase production also contributed to the global supply relief.

Despite a calculated decrease of 3.96 Turkish Liras in international markets, the discount reflected at the pumps in Turkey for gasoline was 99 kuruş due to the implementation of the “Eşel Mobil Sistemi” (sliding scale system or equalization mechanism). The remaining portion was covered by an adjustment in the Special Consumption Tax (ÖTV). This system aims to balance the direct and significant impact of sudden oil price changes on consumers. In addition to the gasoline discount, diesel prices also saw successive reductions in previous days, with a total drop of over 2 Turkish Liras reflected at the pumps on June 16, 17, and 18.

Following these developments, current gasoline prices in major cities decreased to 62.19 Turkish Liras on Istanbul's European Side and 62.03 Turkish Liras on the Anatolian Side. In Ankara, prices fell to 63.14 Turkish Liras, and in Izmir, to 63.42 Turkish Liras. Fuel prices in Turkey are determined by a combination of factors, including Brent crude prices, exchange rates (USD/TL), refinery pricing, tax burden, distribution costs, and dealer margins. Therefore, not every change in global oil prices is reflected proportionally at the pumps.

The temporary peace agreement between the US and Iran aims to end the conflict that began in February, which had escalated geopolitical risks and pushed Brent crude prices up to $126.41. The signing of the agreement and the expectation of the Strait of Hormuz reopening to ship traffic have created significant relief in global oil markets. Experts note that the normalization of tanker traffic in the Strait of Hormuz, one of the world's most critical oil shipping points, has eased supply concerns. However, warnings are also being made that full normalization may take time due to mine risks and infrastructure repairs in the region.

Analysts and market expectations suggest that Brent crude oil prices may continue their volatile trend in the short term. According to Trading Economics' global macro models and analyst expectations, Brent crude is projected to trade at $87.96 per barrel by the end of this quarter, with a potential to reach $101.54 per barrel within 12 months. Depending on the balance of global supply and demand and the course of geopolitical developments, new updates in fuel prices in Turkey may be on the agenda in the coming period.
