Worries about political risks had jolted Italian markets and pressured the euro following reports that Italy's anti-establishment 5-Star Movement and anti-immigrant League may ask the European Central Bank to forgive 250 billion euros of debt as the parties worked to draft a coalition program.
The two populist parties have held six days of talks aimed at putting together a coalition government and ending 10 weeks of stalemate following an inconclusive election on March 4.

Yields on 10-year U.S. Treasuries hit 3.10 percent on Wednesday for the first time since July 2011, continuing to weigh on stocks as investors consider whether U.S. government bonds pose a more attractive option to riskier equities.

The U.S. 10-year Treasury yield rose to as high as 3.104 percent in early Asian trade on Thursday, matching the near seven-year high set on Wednesday.

"If the market continues to trade off U.S. yields and diverging economic data between the U.S. and EU, it's hard to argue against the current direction in yields or the dollar," Stephen Innes, head of trading in Asia-Pacific for Oanda in Singapore, said in a note.
"On the U.S. economic data front, the consumer remains the economy's backbone, and if this robust trend in the retail space continues to build, factor in a bit of wage growth pressure and the U.S. dollar will continue to move higher on the back of higher yields," Innes added.
The dollar index last stood at 93.282. On Wednesday it had touched a five-month high of 93.632.
