Colombia's 12-month inflation rate reached 7.4 percent in April, up from 7.3 percent in March. The acceleration complicates the Banco de la República's easing cycle as traders had priced in continued disinflation to support rate cuts.

The central bank has reduced its benchmark rate from a peak of 13.25 percent to stimulate economic growth. Analysts had expected further deceleration in consumer prices, fueling expectations for aggressive cuts in coming months.

Food and beverage prices contributed to the overall inflation rise last month. Services inflation, particularly education and healthcare, showed persistent strength despite previous rate hikes. Core inflation, which strips out volatile food and energy components, also registered an increase, signaling broad-based price stickiness across the economy.

The data could prompt the Banco de la República to pause its easing cycle. Traders in the local bond market may now price in fewer rate cuts for the remainder of the year. The yield on Colombia's 10-year government bond faces upward pressure as rate cut probabilities diminish, increasing borrowing costs for the government and domestic corporations.

A more conservative approach to rate cuts would likely steepen the front end of Colombia's sovereign yield curve, reflecting near-term policy uncertainty. Longer-duration bonds face increased duration risk if inflation proves more stubborn than projected. Spread compression against U.S. Treasuries might reverse, making Colombian debt less attractive to international investors seeking yield.
