Germany's manufacturing sector faced a deepening downturn at the end of 2025, with output declining for the first time in 10 months in December amid a sustained drop in demand, a business survey showed on Friday. The HCOB final Purchasing Managers' Index (PMI) for German manufacturing, compiled by S&P Global, fell to 47.0 in December from 48.2 in November, a bigger decline than the preliminary reading of 47.7 for the final month of the year.
