LONDON, Dec 13 (Reuters) - European bourses opened on a cautious note on Wednesday despite gains on Wall Street and in Asia as investors await a U.S. Federal reserve meeting and assess the political implications of Donald Trump's setback in a bitter Senate election in Alabama.
The pan-European STOXX 600 slipped 0.1 percent with Paris, Frankfurt and London trading in negative territory.
"Last night's new U.S. records aren't expected to translate through to this morning's open in Europe, where the underlying sentiment is likely to be caution ahead of today's Fed meeting and tomorrow's Swiss National Bank, Bank of England and European Central Bank rate meetings", CMC Markets analyst Michael Hewson said before markets opened.
The pace at which these central banks intend to tighten and normalize monetary policy is seen as a key factor in maintaining the current bull market in 2018.
Higher interest rates are also expected to lift banks stocks, whose revenues and profits have suffered from the historically low cost of borrowing money.

In the UK, industrial-equipment hire company Ashtead gave back its gains of the previous session, losing close to 5 percent after Citi cut its rating for the stock.
