The Colombian peso experienced a surge against the US dollar, driven by aggressive interest rate differentials and robust commodity prices, before central bank intervention and shifting monetary policy initiated a market rebound in August 2026.
Colombian Peso Surge and Economic Drivers
The US dollar in Colombia dropped to multi-year lows, trading near $3.086 according to data published by Corficolombiana. The peso accumulated an appreciation of approximately 18% throughout 2026. In July alone, the local currency advanced an impressive amount, closing the month as the strongest-performing fiat currency globally. Market analysts point to four primary pillars behind this movement: an active carry trade fueled by the Banco de la República holding its benchmark interest rate at 12% while the US Federal Reserve kept rates lower, oil prices hovering around $90 per barrel supported by geopolitical tensions, a weak global dollar index, and political optimism surrounding the incoming presidential administration of Abelardo de la Espriella.
Central Bank Intervention and Policy Shifts
The momentum reversed after the Banco de la República voted to hold its interest rate steady at 12% rather than implementing a widely anticipated 50-basis-point hike, eroding the carry trade advantage. Simultaneously, the monetary authority announced a structural program to accumulate up to US$4.000 millones in international reserves using put option auctions. These options execute automatically when the official market exchange rate (TRM), tracked by the Superintendencia Financiera de Colombia, falls beneath its 20-day moving average. By stepping in as an institutional buyer during periods of excessive peso strength, the central bank established a dynamic price floor.
Market Recovery and Technical Indicators
Technical metrics indicated extreme exhaustion in the downward trend. Weekly charts recorded an unprecedented relative strength index (RSI) oversold reading of 26.5 points, a level never previously documented for the currency pair in weekly timeframes. Following the central bank’s policy pause and reserve auctions, the exchange rate rebounded, closing at an average of $3.230,55 and posting consecutive daily gains. According to market commentary from XTB LATAM analysts, the appreciation cycle has largely exhausted incoming dollar flows, setting near-term trading ranges between $3.080 and $3.200 as the market awaits upcoming domestic inflation data.
