At 46.5 in March, the final Markit Eurozone PMI Composite Output Index was unchanged on the flash reading, confirming that the rate of decline in activity accelerated for the second month in a row to reach the fastest since last November.

Of the four largest euro nations, France saw the steepest downturn with output falling at the fastest rate for four years, while severe contractions were again recorded in Spain and Italy (albeit with the latter showing a marginal easing in the rate of decline). Only Germany continued to see higher business activity, though even there the rate of expansion slowed sharply to near-stagnation.
