The cost of borrowing for Italy's government has reached a new eurozone record of 6.29% in its latest bond auction.The news came as the yield on traded Spanish government bonds rose above 6% for the first time since August.
And official figures from Eurostat showed eurozone industrial production for September down 2% from August.
European markets reacted with uncertainty to the news, with the FTSE down by around 0.5% in early afternoon.
Italy sold 3bn euros ($4.2bn, £2.6bn) of 5-year bonds at a 6.29% yield on Monday.

Use the dropdown for easy-to-understand explanations of key financial terms:
The return to an investor from buying a bond implied by the bond's current market price. It also indicates the current cost of borrowing in the market for the bond issuer.

Yields for all bonds in a particular currency will rise if markets think that the central bank in that currency will raise short-term interest rates due to stronger growth or higher inflation. Yields for a particular borrower's bonds will rise if markets think there is a greater risk that the borrower will default.

Investors are looking to see if Italy can form a new government under the leadership of economist Mario Monti.
Around 200bn euros worth of Italian debt will need to be refinanced by April next year.
Economic slowdown The September fall in industrial production in the eurozone was not as bad as some investors had feared.
However, production in September increased by 2.2% year-on-year in the eurozone, which was below expectations of a 3.3% rise.
"Eurozone manufacturers are clearly now finding life extremely challenging as domestic demand is hit by tighter fiscal policy across the region," said Howard Archer from IHS Global Insight.

By early afternoon on Monday, German, French, British and Italian benchmark indices were all down between 0.5 and 1.5%.
Share values had initially recovered on hopes that changes to the Greek and Italian governments would help resolve the eurozone debt crisis.
However, there are concerns that the eurozone economy could start contracting again by the end of the year.

"In all, then, these data appear to support our view that the eurozone will soon fall back into another fairly deep recession."
