Stronger peso and oil prices shift Colombian investment landscape.

The Colombian peso (COP) experienced a 2.1% appreciation during March 2026, driven by a recovery in global oil prices and key domestic developments. According to the latest analysis from Bancolombia (BVC: BCOLOMBIA / NYSE: CIB), the performance of the currency coincided with the results of national legislative elections and recent monetary policy adjustments by the Banco de la República.

Global energy markets recorded a significant increase in crude prices throughout the month. Brent crude rose 63% to end March at $118 USD per barrel, while West Texas Intermediate (WTI) increased 51% to close at $101 USD per barrel. These price movements have been largely attributed to geopolitical tensions in the Middle East, which continue to influence international commodity flows and investor sentiment.

On the domestic front, the Gran Coalición por Colombia primary election recorded a turnout of more than 5 million voters. Market analysts indicated that the high participation rate was viewed as a positive indicator of institutional stability. Simultaneously, the Board of Directors of the Banco de la República increased the national policy interest rate by 100 basis points, bringing the benchmark rate to 11.25%. This decision aligns with regional efforts to manage inflationary pressures through tighter monetary control.

International market conditions also reflect a shift in expectations regarding the Federal Reserve. Due to ongoing conflict in the Middle East and persistent economic indicators, markets currently anticipate that the US central bank will maintain existing interest rates without cuts for the remainder of the year.

Looking forward to April, the research team at Bancolombia—led by Chief Economist Laura Clavijo, Macroeconomic Manager Jose Luis Mojica, and International and FX Analyst Maria Paula Gonzalez—projects that the exchange rate will trade within a range of $3,625 COP to $3,725 COP. This forecast accounts for continued volatility and heightened uncertainty in both global and domestic financial markets.

The investigation into Colombia’s President comes on the heels of Petro’s visit to Washington & meeting with Trump.

The Drug Enforcement Administration (DEA) has designated Colombian President Gustavo Petro as a priority target as federal prosecutors in New York investigate potential connections to narcotics trafficking organizations. Records indicate that the US Department of Justice is reviewing multiple inquiries dating back to 2022, primarily supported by information from confidential informants.

The investigations involve allegations regarding interactions with the Sinaloa cartel and the possible use of the Paz Total policy to benefit specific traffickers who reportedly contributed to the 2022 presidential campaign. Documents also mention the potential use of law enforcement assets to facilitate the transport of cocaine and fentanyl through maritime terminals. The priority target designation is applied to individuals whom the DEA identifies as having a significant influence on international narcotics distribution.

President Petro has denied any involvement with criminal organizations or the acceptance of illicit funds for his political activities. In a statement released on social media, he suggested that legal proceedings in the US would eventually disprove allegations originating from political opponents. The Embassy of Colombia in Washington stated that the reports are based on unverified and anonymous sources.

“The reported insinuations have no legal or factual basis,” stated the Embassy of Colombia in Washington.

The inquiry has expanded in recent months, with prosecutors in the Eastern and Southern Districts of New York questioning detained individuals about allegations that representatives of the administration solicited bribes in exchange for preventing extradition to the US. It has not been confirmed whether formal charges will be filed against the president, and the White House has stated it has played no role in the independent judicial process.

Portions of the DEA records cite a 2024 interview regarding allegations that former aides and officials from Ecopetrol (NYSE: EC) (BVC: ECOPETROL) were used to launder funds. Ricardo Roa, the president of Ecopetrol, has denied these claims. Simultaneously, the US Department of the Treasury previously sanctioned Petro in late 2025, citing concerns over cocaine production levels, though specific evidence was not made public at that time.

While Petro denies connections to criminal groups, it is important to note that he was a member of the homicidal M-19 guerilla group in Colombia from his teenage years until the group laid down its arms in 1987. Petro served prison time for illegal arms possession due to his activities with the M-19.

Domestic investigations in Colombia are also ongoing regarding the president’s relatives. His son, Nicolas Petro, faced charges in 2023 related to the alleged receipt of funds from a convicted trafficker. Furthermore, the president’s brother, Juan Fernando Petro, has been linked to investigations involving unauthorized negotiations with inmates at the La Picota prison regarding the Paz total framework and extradition protections.

Witnesses currently in US custody who may be relevant to the ongoing probes include former members of the Venezuelan Cartel de Los Soles and various Colombian nationals recently extradited, such as individuals associated with the La Inmaculada organization and the Clan del Golfo (Gulf Clan). Some reports suggest that sums near $500 million COP were discussed in exchange for gestores de paz (“Peace Manager”) status, though these allegations remain under judicial review.
