BERLIN—The downturn in German business activity deepened in September, a preliminary survey showed on Friday, as higher energy costs hit Europe’s largest economy and companies saw a drop in new business.
S&P Global’s flash composite Purchasing Managers’ Index (PMI), which tracks both the manufacturing and services sectors which together account for more than two-thirds of Germany’s economy, fell to 45.9 in September from August’s final reading of 46.9.
