Latin America’s two largest economies took unusual steps this week to prop up their currencies, underscoring growing anxiety over dollar strength and domestic fiscal risks. On Tuesday, the Colombian peso fell 2.5% to 4,250 per dollar, its weakest in three weeks, after unconfirmed reports that the finance ministry was considering direct dollar purchases in the open market. Hours later, Brazil’s central bank disclosed it had entered the dollar futures market for the first time in a decade, selling contracts to support the real.
The peso’s sharp decline was driven by speculation that the Colombian government might tap central bank reserves – estimated at around $60 billion – to buy dollars, a move that would be the first major intervention since the pandemic-driven sell-off of 2020. Analysts at Banco de Bogotá labeled the speculation “premature but not unfounded,” warning that any action must be clearly communicated to avoid fueling panic. “The worst outcome is an intervention that surprises the market,” said one analyst, speaking anonymously.
Meanwhile, Brazil’s central bank surprised markets by returning to the futures market for the first time since 2015, when the country was mired in recession and political turmoil. By selling dollar futures contracts, the bank aims to increase the supply of dollars in the derivatives market, easing speculative pressure without depleting international reserves. The real briefly strengthened on the news, but analysts remain split on whether the measure can deliver lasting stability, especially given unresolved fiscal imbalances.
Both interventions highlight a broader dilemma for emerging markets: how to defend currencies buffeted by high U.S. interest rates and global risk aversion without igniting capital flight. A weaker peso and real inflate the cost of imported goods, worsening inflation that already runs above targets in both nations. While exporters in oil, coffee, and other sectors benefit from improved competitiveness, the overall uncertainty threatens consumer spending and investor confidence.
The coming days will be crucial. Colombian officials have declined to comment, citing market sensitivity, while Brazil’s central bank has not disclosed the size of its futures operation. Market estimates suggest the notional value could run into billions of dollars. For investors, the dual interventions signal that emerging-market currency volatility is entering a new phase – one that may test the limits of conventional policy tools.
