* Futures dip: Dow 0.32 pct, S&P 0.26 pct, Nasdaq 0.40 pct

Italy would enjoy more favorable economic conditions outside of the euro zone, said Claudio Borghi, a eurosceptic who chairs the budget committee of the lower house of parliament.
Borghi later clarified but his comments pushed Italy's bond yields to multi-year highs, sparked a selloff in Italian banks that also pressured euro zone banks.
