The U.S. services sector showed unexpected strength in August, with the ISM Services PMI rising to 55.4% from 54.1% in July. The reading significantly outperformed market consensus estimates of 54.2%, marking the 26th consecutive month of expansion. Growth was driven by sharp increases in the Business Activity Index (61.7%) and the New Orders Index (60.9%), which both jumped more than 2.5 percentage points from the previous month.

Despite the robust headline figure, the report highlighted persistent challenges. The Prices Index rose to 72.6%, its highest level in over three years, signaling continued inflationary pressure within the sector. Meanwhile, the Employment Index remained in contraction territory for a second month at 47.8%. Market participants noted the report as a sign of economic resilience, though the sticky price data may complicate Federal Reserve policy considerations.
