European equities closed higher on Wednesday, but investors remained cautious ahead of the release of the minutes from the Federal Open Market Committee's October meeting.
Fed minutes eyed
The pan-European FTSEurofirst 300 Index closed unofficially 0.1 percent higher at 1,297.5 points, having reversed direction in the afternoon after reports the European Central Bank was mulling setting negative deposit rates.
However, investors continued to keep a keen eye on any sign that the U.S. Federal Reserve might be looking to curb it's current $85 billion-a-month liquidity program.
"Tonight brings the week's main event with the publication of the minutes from the most recent FOMC meeting," Emily Nicol, an economist at Daiwa Capital said in a morning note.
"While Janet Yellen's confirmation hearing at the Senate banking committee last week gave few signals about the likely path for near-term policy, the minutes will be watched closely for any clues as to when the Fed is looking to start tapering."

Speaking at the annual National Economists Club members dinner in Washington, Bernanke said the U.S. central bank would maintain its easy monetary policy for as long as needed and will only begin to reduce bond-buying once it is assured that labor market improvements will continue.
BoE policy watched
In other news, JPMorgan Chase has reached a record $13 billion settlement with federal and state authorities to resolve claims over the bank's sales of mortgage-backed securities that collapsed during the U.S. housing crisis.
Also on Wednesday, The Bank of England's (BoE) monetary policy committee (MPC) expressed "uncertainties" over the durability of the U.K.'s economy recovery, according to the minutes of its last meeting.
The committee also said there "could be a case" for not raising the main interest rate when the country's unemployment rate hits 7 percent. The bank has previously given guidance that it would not consider raising the main interest rate (Bank Rate) from its current 0.5 percent until the jobless rate falls to this level.
