The IMF has today slashed its growth estimates for the euro zone, which was dragged lower by export-powerhouse Germany, Europe's biggest economy and a casualty of the global trade war.
Along with emerging economies, the IMF said the euro zone was a key contributor to the cooling global economy - with matters possibly to get worse.
Britain's painful divorce from the EU was also a destabilising factor, the IMF said, with non-euro UK also stuck in a low-growth gear, though no different than continental Europe.
"Downside risks to the outlook are elevated," said Gita Gopinath, the IMF's chief economist.
"Trade barriers and heightened geopolitical tensions, including Brexit-related risks, could further disrupt supply chains and hamper confidence, investment, and growth," she said.
The IMF said the euro zone would this year reach 1.2%, which was 0.1 points lower from its July estimate.
The growth estimate in 2020 was also slashed to 1.4%, down 0.2 points from the July forecast.
For Germany, growth was revised down to just 0.5% in 2019, 0.2 points lower than the July estimate.
This was a worrying level for an economy seen as the driver of the Europe, especially for eastern Europeans countries where German industrial giants have expanded production.
The IMF said Germany was laid low by a slumping auto market that felt the demand shock of the US-China trade war.
German car makers are also facing tighter anti-pollution costs in the wake of the Volkswagen emissions scandal.
Given the unresolved trade war, the IMF toned down its earlier prediction of a strong rebound for Germany in 2020 and predicted 1.2% growth in 2020, 0.5 points lower than the previous estimate.
The growth projection for Britain, which aims to leave the European Union on October 31, was also knocked slightly lower from July.
The UK economy is expected to grow 1.2% this year and 1.4% in 2020, but this was largely level with the rest of western Europe.
"The extra public spending envisaged by the government should mitigate the cost of Brexit for the economy," said the IMF report.
Given the sluggish picture, the IMF again called on countries with the means to do so to boost public investment and help stimulate the European economy.
This is a very touchy subject among eurozone members, with voters in Germany and the Netherlands loath to help euro zone countries they see as prone to spending beyond their means.
The IMF said the Italian economy would only reach middling growth, with IMF slating an expansion of 0% in 2019 and just 0.5% in 2020.
