Colombia's central bank took steps to halt the peso's significant rally, which saw the currency appreciate nearly 20% against the US dollar in 2026 and reach levels not seen since 2019. On July 31, Governor Leonardo Villar announced that the bank would hold its benchmark interest rate at 12%, a move that surprised many analysts who had anticipated a rate hike given inflation running above 6%. Simultaneously, the central bank unveiled a program to accumulate up to $4 billion in international reserves, explicitly designed to inject dollars into the local market and ease pressure on the peso.
This intervention is intended to address the negative impact of a strong peso on Colombian exporters, such as those in the coffee, flower, and banana sectors. These exporters, who earn revenue in dollars but pay expenses in pesos, faced compressed margins due to the currency's appreciation. Analysts like Alvaro Vivanco of Wells Fargo remarked that the strategy of holding rates and buying dollars is a clear move to weaken the currency, contradicting the "peso stronger forever" narrative.
The reserve accumulation program will commence with monthly put option auctions, with the first capped at $400 million and scheduled for August 3. The bank will only buy dollars if the peso falls below its 20-day moving average. Officials noted that a similar method added about $1.5 billion to foreign reserves in 2024. The new $4 billion target, if fully executed, would significantly boost Colombia's existing reserves, which stood at approximately $64.6 billion as of mid-2025. The central bank aims to solve two problems simultaneously: avoid attracting more foreign capital through rate hikes while directly supplying dollars to the market.
The market reaction is anticipated to be a sharp depreciation of the peso on Monday, August 4, as long positions built up post-election are likely to unwind. Brendan McKenna of Societe Generale stated that the peso "will open sharply weaker come Monday as a result, and that depreciation may continue." This move aligns Colombia with other regional countries like Uruguay and Costa Rica that have intervened to cool their currencies this year. The success of the program hinges on market participation in the initial auctions, with strong uptake confirming the bank's credibility.
The political context also plays a role, with elections on the horizon, as the government has an interest in supporting exporters and managing inflation. While a stronger peso helps contain imported inflation by making dollar-priced goods cheaper, a 20% appreciation effectively acts as a significant pay cut for agricultural exporters in local-currency terms. The central bank's actions represent a deliberate push to guide the peso back down, signaling a bumpier ride ahead for those holding Colombian assets.
