European stocks edged higher in the opening minutes of trading Wednesday as investors maintain a cautious stance ahead of Wednesday's rate decision in economic projections from the U.S. Federal Reserve.

Most benchmarks added modest gains at the start of trading, although the advances were limited owing to a tentative atmosphere ahead of the 2:00 PM ET rate announcement from Washington, and the chairwoman Janet Yellen's press conference 30 minutes later, with the U.S. dollar slipping 0.05% to 91.75 and the broadest measure of regional share prices, the Stoxx Europe 600 index, marked down 0.02% at 382.00 points.

Britain's FTSE 100 added 8 points, or 0.11%, at the opening bell even as the pound held steady at 1.3527 against the dollar, with consumer cyclical and financial stocks propping up gains. The benchmark's biggest mover to the upside was U.K. home improvement retailer Kingfisher Plc (KGFHY) , which gained 6.7% after it reported stronger-than-expected first half earnings and announced a small share buyback.
