Ecuador-Colombia Trade War at Maximum Escalation: 50% Tariffs Both Sides

Escalation Timeline

The bilateral trade conflict between Ecuador and Colombia has reached its most severe level since the 2008 diplomatic rupture following the Angostura raid, with both countries now imposing 50% reciprocal tariffs on each other's imports.

Date	Action	Actor
January 2026	Ecuador imposes 21% tariff on select Colombian imports	Ecuador
February 2026	Colombia retaliates with 25% tariff on Ecuadorian goods	Colombia
February 26, 2026	Ecuador escalates to 50% on all Colombian imports, effective March 1	Ecuador
March 2026	Colombia matches with 50% tariff on Ecuadorian imports	Colombia
March 2026	Ecuador raises OCP pipeline tariff surcharge by 900%	Ecuador
March 2026	Colombia suspends electricity exports to Ecuador	Colombia

The conflict originated in a dispute over Colombian poultry dumping allegations and phytosanitary restrictions on Ecuadorian agricultural products, but has rapidly expanded into a full-spectrum trade war touching every major bilateral trade category.

Trade at Risk

Bilateral trade between Ecuador and Colombia totaled approximately $2.8 billion in 2025, making Colombia Ecuador's second-largest trading partner in the region after the United States.

Trade Flow	2025 Value	Key Products
Ecuador → Colombia	~$1.1B	Canned tuna, palm oil, processed foods, cacao products, shrimp
Colombia → Ecuador	~$1.7B	Vehicles/auto parts, pharmaceuticals, plastics, petrochemicals, processed foods, textiles
Total bilateral	~$2.8B	—

A 50% tariff on these flows is functionally prohibitive for most product categories. Preliminary data suggests March 2026 bilateral trade volumes fell 40-55% relative to the prior-year period.

Pipeline Tariff Escalation

One of the most consequential dimensions is Ecuador's 900% increase in the transit tariff for Colombian crude oil flowing through the OCP (Oleoducto de Crudos Pesados) pipeline. Colombia's state oil company Ecopetrol uses the OCP to export crude from the Putumayo basin through Ecuador to the Pacific coast.

OCP Pipeline Parameter	Pre-Escalation	Post-Escalation
Transit tariff ($/bbl)	~$2.50-3.00	~$25-30
Colombian volume (bpd)	~20,000-30,000	Under review
Annual Colombian transit revenue	~$25-30M	~$200-250M (if sustained)

The tariff increase makes pipeline transit economically unviable for most Colombian crude grades, effectively forcing Ecopetrol to reroute Putumayo production through the longer and more expensive Colombian Pacific pipeline system.

Electricity Suspension

Colombia's decision to suspend electricity exports to Ecuador removes approximately 200-300 MW of import capacity that Ecuador relied on during peak demand and hydroelectric shortfalls. This compounds the Mazar/Paute hydroelectric risk and raises the probability of rationing scenarios if dry season conditions persist.

Sector-Level Impact

Sector	Ecuador Exposure	Colombia Exposure
Automotive	Colombian vehicles/parts supply disrupted	Ecuadorian market access lost
Pharmaceuticals	~15% of Ecuador imports from Colombia	Revenue loss
Processed foods	Colombian snacks, beverages affected	Ecuadorian tuna, cacao access lost
Plastics/petrochemicals	Manufacturing input costs rise	Market contraction
Agriculture	Colombian produce prices surge	Ecuadorian palm oil, flowers affected

CAN (Andean Community) Implications

Both countries are members of the Comunidad Andina de Naciones (CAN), which is supposed to guarantee free trade among Andean members. The reciprocal 50% tariffs violate CAN commitments, and the CAN General Secretariat has called for dialogue. However, CAN lacks effective enforcement mechanisms, and neither country has shown willingness to de-escalate.

What to Watch

• CAN mediation attempts — the General Secretariat may convene emergency sessions; any agreed framework for de-escalation would be market-positive
• March-April bilateral trade data — customs figures from both countries will quantify the real-world trade destruction
• Ecopetrol pipeline rerouting — any formal withdrawal from OCP transit would be a structural shift in binational energy logistics
• Colombian electricity export resumption — timing and conditions; this has direct implications for Ecuador's energy security
• Substitute sourcing patterns — Ecuadorian importers shifting from Colombian to Peruvian, Brazilian, or Chinese suppliers; trade diversion data will emerge in Q2
• Diplomatic channels — presidential-level engagement; the Petro-Noboa relationship has been adversarial since late 2025
