The Catalan independence referendum has created a tumult in the southern European country. The regional government said that 90 percent of people voted in favor of independence, while the national authorities said the referendum was illegal. Catalan officials said that more than 800 people were injured during clashes with the police, which tried to prevent people from voting.
More broadly, European stocks kept their positive momentum after fresh data releases. Manufacturers in the euro zone reported their most productive month in September since 2011. IHS Markit final manufacturing purchasing managers' index hit 58.1 last month, having reached 57.4 in August.
"The euro zone manufacturing sector is in fine form, and likely continued to provide firm support for GDP growth in the third quarter," Claus Vistesen, chief euro zone economist at Pantheon Macroeconomics said in a statement.
Furthermore, unemployment data in the euro zone remained at their lowest level seen since February 2009. In August, there was 9.1 percent of unemployed people in the region, down from 9.9 percent a year ago.
