Market Summary - September 11, 2026

Wall Street Rebounds Despite Inflation Concerns

The opening session on Wall Street shows a notable rebound after previous declines, despite the August Consumer Price Index (CPI) inflation report indicating persistent inflationary pressures. The Supercore CPI, which excludes housing costs, rose to 3.01% year-over-year, raising concerns about potential Federal Reserve rate hikes.

Inflation Data Overview

The August CPI report revealed a headline inflation increase of 3.4% year-over-year (0.4% month-over-month), while core inflation remained steady at 2.4% year-over-year. The Supercore CPI's monthly increase of 0.51% was particularly alarming, prompting immediate reactions in the debt markets.

Market Reactions

Following the inflation data, yields on 10-year US Treasury bonds briefly surpassed 5.0% before stabilizing around 4.92%. The futures market adjusted quickly, with a nearly 90% probability now assigned to a hawkish move by the Fed in their upcoming September meeting. Despite these higher yields, stock indices are showing gains, buoyed by a significant drop in oil prices, which alleviates some inflationary concerns.
