By San José, Costa Rica — SAN JOSÉ – Costa Rican drivers and households are bracing for another shift in energy costs after the Regulatory Authority for Public Services (ARESEP) approved a new fuel price structure. The adjustment, which reflects fluctuations in the international market, will see a significant increase in the price of diesel, a modest rise for Super gasoline, and a marginal decrease for Regular gasoline, creating a mixed financial impact across the country.
The new prices are set to take effect the day after the official resolution is published in the government’s official gazette, La Gaceta. This provides a brief window for consumers to purchase fuel at the current rates before the change is implemented at all service stations nationwide. The most substantial change will be felt by the commercial and transportation sectors, as diesel is slated for a ₡13 per liter increase.
To better understand the regulatory framework and economic implications behind the constant fluctuations in fuel prices, TicosLand.com consulted with Lic. Larry Hans Arroyo Vargas, an expert in corporate and regulatory law from the prestigious firm Bufete de Costa Rica.
In Costa Rica, the final price of fuel is not determined by free market competition but by a technical pricing model managed by ARESEP. This model incorporates international crude oil prices and the dollar exchange rate. However, a significant portion of what consumers pay at the pump is the ‘impuesto único a los combustibles,’ a fixed tax per liter that does not decrease even when international oil prices fall. This rigid tax structure limits the potential for significant price reductions for consumers and businesses, creating a constant challenge for the national economy’s competitiveness, particularly in the logistics and transportation sectors.

The expert’s comment underscores a critical point: the fixed nature of the ‘impuesto único’ is a key reason why Costa Rican consumers rarely see the full benefit of falling international oil prices. This structural reality presents an ongoing challenge to our economy’s competitiveness. We thank Lic. Larry Hans Arroyo Vargas for his clear and valuable insight.
Under the new tariff schedule, Super gasoline will climb by ₡3, moving from ₡753 to ₡756 per liter. In a surprising turn, Regular gasoline will see a slight reduction of ₡1, dropping its price from ₡756 to ₡755 per liter. This adjustment makes Regular gasoline momentarily cheaper than Super, a nuance that drivers will note at the pump. Diesel fuel will experience the most pronounced hike, jumping from ₡670 to ₡683 per liter.
The changes also extend to household energy, with the 25-pound cylinder of Liquefied Petroleum Gas (LPG), a staple for cooking in many Costa Rican homes, set to increase by ₡41. The price will rise from its current ₡7,399 to ₡7,440. While seemingly small, this consistent upward pressure on LPG contributes to the rising cost of living for many families.
In its official communication, ARESEP clarified that the price adjustment is a direct response to the real import costs reported by the Costa Rican Oil Refinery (RECOPE). The calculation is based on the landed cost of fuel shipments that arrived in the country between May 8 and June 11, 2026. This methodology ensures that domestic prices are tethered to the global energy landscape, for better or worse.
The regulatory body pointed to ongoing volatility in international oil prices as the primary driver for this latest adjustment. Geopolitical tensions, particularly in the Middle East, continue to exert upward pressure on crude oil, which directly impacts the acquisition costs for import-dependent nations like Costa Rica. These external factors are beyond the control of local authorities, making domestic fuel prices susceptible to frequent changes.
The economic implications of this adjustment are multifaceted. The sharp rise in diesel costs is expected to have a cascading effect, potentially leading to increased prices for goods and public transportation as logistics companies pass on their higher operational expenses to consumers. Conversely, the minor decrease in Regular gasoline offers a sliver of relief, though it is unlikely to offset the broader inflationary pressures from the diesel and LPG hikes.
As the publication in La Gaceta looms, consumers are advised to plan accordingly. The forthcoming price shift serves as another reminder of Costa Rica’s vulnerability to global energy market dynamics and the continuous challenge of balancing economic stability with international market realities. For now, all eyes are on the service stations as the country awaits the official implementation of the new rates.
