Colombia Peso Dollar Exchange Rate: August 2026 TRM Update

Colombia’s central bank just put its own money behind the peso trade. On July 31, the Banco de la República’s board voted to start buying up to USD 4 billion in international reserves, and the first auction — USD 400 million — ran on Monday, August 3. That same day, the TRM (Tasa Representativa del Mercado, Colombia’s official daily exchange rate, calculated by the Superintendencia Financiera from the prior session’s trading) stood at COP 3,144.14 per dollar — the benchmark behind the Colombia peso dollar exchange rate for August 2026 (Portafolio). If you’re converting USD income into pesos this month, this is the first concrete official response to a rally that has been squeezing your purchasing power for weeks. This account draws directly on the central bank’s own board statement, cross-checked against same-day market reporting from Portafolio, El Colombiano, and La República — the same sourcing approach we’ve used to track every move in this rally.

Quick answer: As of Monday, August 3, 2026, the TRM is COP 3,144.14 per dollar. The Banco de la República began a monthly dollar-purchase program the same day, but it’s explicitly designed to slow the peso’s rise, not reverse it.

What the central bank actually announced

The board’s July 31 decision authorizes gradual purchases of up to USD 4 billion in reserves through monthly put-option auctions, according to the bank’s own statement (Banco de la República). The first call was published that same day, with the inaugural auction held August 3 for a quota of up to USD 400 million; the awarded options can be exercised between August 4 and 31, 2026 (El Colombiano). The bank used the same mechanism in 2024, when it accumulated close to USD 1,500 million in reserves (La República).

The catch is the trigger: option holders can only sell dollars to the bank when the TRM sits below its 20-day moving average (Portafolio). That’s a deliberate design choice — the bank buys dollars only when the peso is strong, which both rebuilds reserves and leans gently against further appreciation, without functioning as a hard floor.

Why now: a 9% July for the peso

The program lands after one of the peso’s strongest months in years. The dollar opened July near COP 3,441 and closed the month at COP 3,132.42, an accumulated drop of roughly COP 308. That’s a monthly fall of about 9% for the dollar — equivalent to a roughly 9.9% gain in peso terms — according to FXStreet. Intraday trading briefly touched levels near COP 3,086–3,098, last seen in 2019, extending the seven-year low the dollar hit in late July and building on a rally that was already gathering pace a week earlier. Colombia’s benchmark interest rate, held at 12% on July 31, keeps peso assets attractive to foreign investors. A forced repatriation of pension-fund holdings and a weaker dollar globally have added to the same pressure, according to El Tiempo.

Will it reverse the rally? Analysts say no

Don’t read this as the central bank calling a bottom. María Claudia Lacouture, president of AmCham Colombia, called the purchase program “an opportune measure” to support exporters hurt by the strong peso, but added it’s “not a sufficient solution” on its own (Infobae). Portafolio’s market roundup similarly found analysts split on whether the dollar even bounces meaningfully from here, with one view holding the intervention “moderates” the decline rather than stopping it (Portafolio). Because the mechanism only lets the bank buy when the TRM is already below its 20-day average, it’s built to smooth the trend, not fight it outright.

What the August 2026 Colombia peso dollar exchange rate means for your budget

For now, the Colombia peso dollar exchange rate in August 2026 is still historically low, and the purchase program hasn’t materially moved it — COP 3,144.14 is barely above the seven-year low set days earlier.

Quick reference — what USD income converts to in pesos:

USD amount	At August 2026’s TRM (3,144.14)	At the July 2026 open (~3,441)	A year earlier (~4,180)
1,000	COP 3,144,140	COP 3,441,000	COP 4,180,000
2,000	COP 6,288,280	COP 6,882,000	COP 8,360,000
3,000	COP 9,432,420	COP 10,323,000	COP 12,540,000

If you’re budgeting rent, groceries, or a monthly transfer in Medellín, that table is the real cut to what dollar income buys compared with a year ago; see how that gap has already shown up in rising costs for expats.

Treat this program as a signal the central bank is uncomfortable with the pace of the rally, not as a guarantee the dollar rebounds. The auctions run monthly, so watch for the next call’s quota size — a much larger one would say more about the bank’s resolve than this first USD 400 million test did.

As always with COP figures, check a live source like the Superintendencia Financiera’s certified TRM before wiring money or comparing budgets.
