Argentina’s monthly inflation likely fell below 2% in June for the first time this year, according to private estimates released days ahead of the official data. Consultancy C&T Asociados projected a 1.9% rise in consumer prices for the Greater Buenos Aires region, while the central bank’s survey of market expectations pointed to a 2% print—down from 2.1% expected a month earlier. The decline follows four consecutive weeks of decelerating food-price increases, with a weekly gauge showing an average 0.8% rise in early July, the slowest pace in five months. Yet a 5% depreciation of the official peso during June, driven by dollar demand for hedging and lower export revenues, has yet to feed into retail prices, leading economists in Buenos Aires to warn that July inflation could be higher due to passthrough lag and seasonal factors.

The disinflation pulse extends beyond Argentina. Brazil’s benchmark IPCA index rose just 0.16% in June, half the consensus forecast and the lowest rate since October 2025. Cheaper freight, itself reflecting the ebbing of the Middle East conflict’s oil-price shock, combined with improved harvests to push food and beverage prices down 0.24% on the month. The diffusion index—measuring the share of items posting increases—fell to its lowest in nine months. In São Paulo, analysts caution that a potential El Niño-driven drought could lift energy tariffs and food costs later in the year, testing the sustainability of the benign readings.

In Colombia, the peso’s rally to near 3,000 per dollar—a 24% gain over twelve months—has amplified the disinflationary effect of the central bank’s 12% policy rate. Capital inflows attracted by the high carry trade and renewed confidence in the oil and coal sectors have pushed the currency to levels last seen in 2018. While some strategists at Bogotá brokerages see room for a further slip to 2,800, others warn the appreciation could erode export competitiveness and reverse abruptly if fiscal reforms promised by the incoming government fail to materialise.

Across the three economies, a common thread runs: easing geopolitical tensions in the Middle East have pulled crude oil off its conflict peaks, lowering fuel and freight costs just as bumper agricultural harvests damp food prices. The result is a rare synchronized dip in measured inflation. The next factual milestone is Argentina’s official June CPI release on Tuesday, which will confirm whether the 2% psychological barrier has been breached in the largest regional economy. In Brazil, attention turns to the central bank’s assessment of core services inflation, while Colombia awaits the new administration’s fiscal package to gauge whether the peso’s strength has a policy anchor.
