According to the final version of S&P Global's Services PMI survey released on Wednesday, the headline index came in at 55.6 in April, above the flash estimate released midway through last month of 54.7. The final Composite PMI subsequently was revised higher to 56.0 from 55.1.

That still left both below March's levels, when the Services PMI came in at 58.0 and 57.7, suggesting a slight deterioration in broad business conditions last month. Still, with both readings still well above the 50.0 mark that separate expansion from contraction, the PMI data suggests the US economy continued to grow at a reasonable pace last month.
