Tensions between Ecuador and Colombia have escalated after Ecuador raised the tariff for transporting Colombian crude oil through its Sistema de Oleoducto Transecuatoriano (SOTE) from $3 to $30 per barrel, a 900% increase effective January 23, 2026. This move, justified by Ecuador as a reciprocal measure after Colombia’s suspension of electricity supply to Ecuador and imposition of 30% tariffs on Ecuadorian imports, signals further strain in bilateral energy and trade relations. The elevated transport costs directly impact Ecopetrol’s export operations, prompting potential shifts in Colombia’s crude logistics strategy in the near term.
Ecuador’s government, represented by Minister of Environment and Energy Inés Manzano, formalized the tariff increase via a resolution by the Agencia de Regulación y Control de Hidrocarburos (ARCH). The adjustment is framed as a responsible legal and technical decision, conveying a strong political message linked to reciprocal actions taken by Colombia in the context of regional security issues, including narcotrafficking and organized crime along the shared border. Ecopetrol reportedly transports approximately 12,000 barrels daily through the SOTE pipeline, from Colombia’s southern oil fields to the Ecuadorian Pacific coast for export. The new $30-per-barrel tariff significantly raises Ecuador’s revenue from this service but increases operational costs for the Colombian state oil company.
The tariff hike follows Colombia’s suspension of electricity exports to Ecuador on January 22, 2026, and its announcement of a 30% import tax on a broad range of Ecuadorian goods effective February 1, 2026. In response to these actions, Ecuador implemented its own security-related tariffs targeting Colombian imports and raised crude transport fees, signaling a tit-for-tat pattern. Colombian private sector pipelines, such as the Oleoducto de Crudos Pesados (OCP), which transport crude from private firms, remain unaffected by the increased tariffs.
Industry analysts note the tariff hike affects a marginal share of Colombia’s total output—approximately 1.5% based on Ecopetrol’s quarterly data—though the move dents Ecuador’s reputation regarding contract stability. Colombian stakeholders are expected to evaluate alternative transport mechanisms such as coastal tanker shipments to mitigate higher pipeline costs. The ongoing bilateral dispute, which also encompasses unresolved border security cooperation, continues to inject uncertainty into regional oil transit logistics and market dynamics. Diplomatic talks proposed for late February have yet to be scheduled definitively, leaving the situation in flux.
