A closely watched survey is showing that the 19-country eurozone is losing some economic momentum and that its largest economy, Germany, is at the heart of the slowdown.

Financial information company IHS Markit says its purchasing managers index — a broad gauge of economic activity — for the eurozone fell to a 19-month low of 52.9 in August from 53.2 the previous month. The fall was unexpected as the initial estimate for August was 53.3.

Anything above 50 still indicates expansion and IHS Markit says the August reading is pointing to quarterly economic growth of 0.3 percent.

The firm's chief economist Chris Williamson says Monday the survey was "clearly disappointing" and that it may fuel expectations of a further stimulus package from the European Central Bank this week.
