U.S. CPI rose 0.6% in September as Argentina inflation hit 2%
Annual U.S. CPI registered 3.6% while Core inflation eased to 2.4% YoY.
U.S. consumer prices increased in September 2026, with the headline CPI-U rising 0.6% from the prior month. The annual CPI rate registered 3.6% year-over-year. Argentina's consumer price index for September showed a monthly rise of roughly 2.0%.
Data released on Thursday, 15 October, confirmed the increase met expectations. The 3.6% year-over-year figure reflected a modest slowdown from previous months.
Core CPI, which excludes food and energy, advanced 2.4% on a year-over-year basis. This reading, also released on Thursday, 15 October, indicated underlying inflation remained subdued.
Argentina's September inflation rate was recorded between 1.9% and 2.1% for the month, according to data published on Tuesday, 13 October. The figure suggested a slight acceleration from earlier estimates. The monthly pace remained well above the central bank's target range.
Together, the U.S. data pointed to persistent but moderate price pressures, while Argentina continued to grapple with higher inflation dynamics. The releases came ahead of upcoming monetary policy meetings in both jurisdictions.
Analysis
The U.S. headline CPI rise of 0.6% month-over-month, combined with a 3.6% annual rate, indicates that inflation is still above the Federal Reserve's 2% objective. Such a level reduces the room for aggressive rate cuts and may keep policy rates steady in the near term. The data also suggest that price pressures have not accelerated sharply, which could temper concerns about a rapid inflation resurgence.
Core CPI's 2.4% year-over-year pace shows that underlying inflation, stripped of volatile food and energy components, remains modest. Policymakers may focus on the Core reading when assessing the durability of inflation trends, potentially shaping future guidance on monetary tightening or easing.
Persistent high inflation can erode real wages and increase pressure on the government to tighten monetary policy, despite potential growth costs. The contrast with the United States, where inflation is moderating, highlights differing macroeconomic challenges across the two economies.
