Colombia’s Sunday runoff could snap the peace process—will a Trump-backed hardliner restart full-scale war?

Colombians vote on Sunday in a presidential runoff that pits Abelardo de la Espriella, a hard-right lawyer backed by the White House, against leftist senator Iván Cepeda. The contest is framed as a referendum on the country’s “stumbling” peace process and on how Colombia manages strained ties with Washington. De la Espriella has vowed to return to full-scale military confrontation with armed groups, signaling a potential reversal of the post-2016 trajectory. The Guardian and France 24 both describe the election as occurring amid the most violent period in years, with the outcome likely shaping the next phase of Colombia’s decades-long armed conflict. Strategically, the runoff is not only domestic politics but also a test of external alignment and security doctrine. A de la Espriella victory would likely shift Colombia toward a more coercive counterinsurgency posture, with implications for negotiations, ceasefire enforcement, and the political space for armed actors. Cepeda’s leftist platform, by contrast, is positioned as a brake on that hard turn, keeping the peace process as the central policy axis. The United States is a key stakeholder because the race is explicitly described as Trump-backed, meaning Washington’s preferences could translate into funding priorities, intelligence cooperation, and diplomatic pressure. The Revolutionary Armed Forces of Colombia (FARC) is referenced as part of the conflict landscape, underscoring how quickly a policy change could affect armed-group behavior and regional stability. Market and economic implications are likely to concentrate in security-sensitive sectors and risk premia rather than in a single commodity shock. If de la Espriella’s pledge to resume full-scale confrontation gains traction, investors typically price higher tail risk for infrastructure, logistics, and local production in conflict-affected regions, which can raise insurance and security costs. Colombia’s currency and sovereign spreads would be the most direct financial transmission channels, as markets often react to election-driven policy uncertainty and potential escalation in violence. Defense and security procurement, private security services, and logistics/transport resilience spending could see upward pressure, while sectors exposed to rural access—agro-processing supply chains and extractive operations near contested areas—may face higher operational friction. While the articles do not provide specific figures, the direction of impact is skewed toward higher risk pricing and cost inflation if the runoff produces a hardline mandate. The next watchpoints are the immediate post-election signals: cabinet appointments, early executive orders on security posture, and any public commitments on whether negotiations or ceasefire mechanisms will be expanded or dismantled. Investors and analysts should monitor statements tied to “full-scale military confrontation,” as well as any operational indicators such as increased tempo of security forces in previously stabilized zones. A key trigger for escalation would be the government’s willingness to move from targeted operations to broader offensives, especially if armed groups respond with retaliatory violence. Conversely, de-escalation would be signaled by renewed engagement with political channels connected to the 2016 peace framework and by measurable reductions in violence metrics. The timeline is tight: the runoff outcome on Sunday should quickly set the tone for the first 30–90 days, when policy direction becomes operational rather than rhetorical.

Geopolitical Implications

• 01

  The election is a direct test of whether Colombia will prioritize negotiated peace mechanisms or coercive counterinsurgency, with consequences for armed-group behavior and regional stability.

• 02

  U.S. influence is likely to be more pronounced if the White House-backed candidate wins, affecting intelligence cooperation, diplomatic messaging, and conditionality around security policy.

• 03

  A policy reversal could strain ceasefire enforcement and complicate any future mediation efforts, increasing the likelihood of sustained violence and spillover pressures.

Key Signals

• —Post-election cabinet and security appointments signaling whether the administration will operationalize “full-scale military confrontation.”
• —Changes in the operational tempo and geographic focus of security forces in areas linked to the peace process.
• —Public messaging on negotiations/ceasefires versus offensives, including any references to the 2016 framework.
• —Early U.S.-Colombia diplomatic coordination cues—statements, visits, or intelligence cooperation announcements.
