NEW YORK — The Colombian peso is on track for its sharpest decline in three months after the central bank unexpectedly paused rate hikes and announced a program to accumulate dollar reserves, signaling a deliberate shift against further currency strength.
The decision removes a key pillar of support for the peso, which has been the world's best-performing currency in 2026. The reserve buildup program means the central bank will actively purchase U.S. dollars, increasing demand for the greenback and supplying pesos to the market.
The peso trades near a multi-year high of approximately 3,132 pesos per U.S. dollar, reflecting a rally of roughly 20 percent against the dollar over the past year — one of the strongest revaluations of the century.
In June alone, the currency gained 7.4 percent against the dollar, according to Bancolombia data — the strongest monthly surge in roughly a decade.
High domestic interest rates have been the primary driver of peso strength since late 2024, fueling a carry trade in which investors borrowed in lower-yielding currencies to invest in Colombian assets and capture the yield differential.
Other domestic factors contributed to the rally. President Abelardo de la Espriella's administration raised the minimum wage 22 percent this year, boosting internal demand and attracting capital inflows. The central bank also took on a significant amount of external debt, making Colombia one of the top countries paying substantial interest in dollars relative to exports. Rising tourism and foreign investment added further demand for the local currency.
A softer U.S. dollar during certain periods amplified the move, as a falling dollar index mechanically supports currencies heavily traded against it.
Fiscal deterioration and technical signals suggesting the U.S. dollar is oversold against the peso have led some analysts to flag rebound risk in USD/COP — a sign carry trade dynamics may be shifting.
The rate pause hits the short end of Colombia's yield curve directly, compressing the interest rate differential that made the carry trade attractive and narrowing spreads between Colombian and U.S. fixed-income assets. With the central bank now actively buying dollars, the scale and pace of reserve accumulation will determine how quickly those dynamics unwind.
