100% Tariffs: Ecuador-Colombia Trade War Begins May 1

The Ecuador Colombia tariffs that went live this morning at 100% are the sharpest intra-Andean trade rupture in two decades — and they land in the middle of a Colombian election cycle.

The Ecuador Colombia tariffs entered force at 100% on May 1, more than tripling from the previous 30% level. Ecuador’s government framed the move as retaliation for what Quito alleges are guerrilla incursions backed by Bogotá. Colombian President Gustavo Petro responded by accusing Daniel Noboa and former Colombian president Álvaro Uribe of a coordinated “alliance to subvert Colombian elections” — the first-round presidential vote is set for May 31.

The Rio Times, the Latin American financial news outlet, reports that the tariffs cover thousands of Colombian product lines, with the heaviest impact on textiles, food processing, manufacturing parts, and agricultural goods. Bilateral trade between Colombia and Ecuador reached approximately $3.2 billion in 2024, making Colombia Ecuador’s third-largest trading partner. The 100% rate effectively closes the Ecuadorian market to most Colombian exporters who lack the margin to absorb a doubling of landed cost.

How the Ecuador Colombia Tariffs Escalated

The trigger was a series of reported guerrilla movements across the southern Colombia-Ecuador frontier. Noboa’s government claimed dissident FARC factions and ELN cells operating with Colombian-side tolerance had penetrated Carchi, Imbabura, and Sucumbíos provinces. Ecuador called the situation a sovereign violation and announced the tariff escalation along with a 9-province curfew running from May 3 to May 18.

Petro’s response framed the tariffs as electoral interference. He pointed to the timing four weeks before Colombia’s first-round vote and to the alignment between Noboa and the Centro Democrático opposition that Uribe founded, then launched Plan Candado in Valle del Cauca — armored cavalry deployment plus Colombian Air Force overflights — to counter the narrative that Bogotá lacks border control. Both presidents traded accusations through X over the past 72 hours.

Who Loses From the Ecuador Colombia Tariffs

The Andean Community (CAN) — the regional trade bloc that includes Bolivia, Colombia, Ecuador, and Peru — was designed to prevent exactly this kind of unilateral escalation between members. The CAN tariff schedule provides preferential rates between members, and the 100% rate Noboa imposed violates those provisions. Bogotá has signaled it will challenge the move through CAN dispute mechanisms, but the timeline is months not weeks.

For Colombian exporters, the immediate hit is concentrated in roughly 5,000 product lines. Pasto and Ipiales — Colombian cities on the Ecuadorian border — face the sharpest contraction, with truck-based commerce already down 40% since the original 30% tariff went into force in mid-April. Ecuadorian importers face their own price shock; Colombian-sourced food products and consumer goods will become harder to find or substantially more expensive.

Why the Election Timing Matters

Petro cannot run for reelection. His designated successor faces a crowded field led by leftist senator Iván Cepeda and rising right-wing lawyer Abelardo de la Espriella, who explicitly admires Bukele, Milei, and Trump and has built his platform around mano dura against guerrilla violence. Border instability boosts that message.

Petro’s “Uribe-Noboa alliance” framing is therefore strategically rational regardless of whether the alliance actually exists. If voters perceive coordinated foreign pressure backing the Colombian right, the leftist coalition gains a unifying enemy; if they perceive the tariffs as a foreign-policy failure, the right gains. May 31 is when that political market settles.

What the Ecuador Colombia Tariffs Mean for the Region

For markets, the dispute is the most visible test yet of CAN cohesion in the Trump era. Both Noboa and Kast in Chile have aligned with Trump’s continental security architecture established at the March Shield of the Americas summit, while Petro and Lula represent the alternative bloc that gathered in Barcelona alongside Sheinbaum on April 17. The tariffs operationalize the political alignment in trade policy.

For investors tracking Andean energy and trade flows, the dispute introduces a new layer of intra-regional friction at a time when Iran war oil prices are already squeezing the region. Ecuadorian crude exports route partly through Colombian Pacific terminals, and any retaliatory measures from Bogotá could affect that flow. The May 31 election outcome will determine whether the dispute escalates further or de-escalates into managed grievance.
