US stocks fell Friday as fresh inflation data pointed to more hawkish monetary policy, closing out steep losses for the week, month, and third quarter.

The Federal Reserve's preferred inflation gauge — the core personal consumption expenditures price index — increased 4.9% in August from a year ago, up from 4.7% in July and above forecasts. Markets have been selling off as central bankers reinforce their intent to keep policy tight until inflation cools sufficiently, while soaring bond yields have heightened turmoil across global markets, most recently in the UK.

For the week, the S&P 500 and Dow lost 3%, and the Nasdaq dipped 0.3%. For the month of September, the S&P 500 and the Dow plunged more than 9%, and the Nasdaq tumbled 10%. For the third quarter, the S&P 500 gave up 6%, while the Nasdaq lost nearly 5%, and the Dow sank more than 7%.
