European shares closed marginally higher on Wednesday, after a bumpy day of trading, as investors looked ahead to the much-anticipated U.S. Federal Reserve's policy statement.
The pan-European FTSEurofirst 300 provisionally closed 0.1 percent higher, at 1,318.51 points.
But some major stock markets ended the day in the red, with the Spanish benchmark IBEX down around 1.4 percent and Italy's MIB some 1.6 percent lower. Fears about the region's banking sector following the results of Europe-wide stress tests weighed on these countries, with Italian bank stocks particularly badly hit on Wednesday.
Shares in Banca Monte dei Paschi di Siena were suspended when they hit a lower limit earlier in the day. The bank fared badly in the stress tests, and was identified as having the largest shortfall in capital when the results were published on Sunday.
