**Argentina’s September 2026 monthly CPI print faces a tight contest between the 1.6-1.8% and 1.9-2.1% brackets, reflecting trader views that disinflation will hold near recent levels but could edge higher on seasonal or regulated-price effects.** August’s 1.7% MoM reading—the lowest in 14 months—followed July’s 2.1% and June’s 1.9%, with core inflation steady near 1.8% and year-to-date accumulation at 21.3%. The Central Bank’s REM survey points to 1.8% for both August and September amid a 30% 2026 annual forecast, supported by the Milei administration’s fiscal surplus, peso crawling-peg, and subdued money growth. Key swing factors include the pace of utility and transport adjustments, food-price volatility, and any shift in the exchange-rate band. The September data, due mid-October, will test whether sub-2% prints become the new baseline or face reacceleration risks from domestic demand or external shocks.
