Equities on both sides of the Atlantic dropped after the latest US jobless data fuelled expectations the Federal Reserve will announce plans to begin cutting back its bond-buying program at its meeting next month.
Initial claims for unemployment benefits dropped 15,000 last week to a seasonally adjusted 320,000, the lowest level since October 2007, according to the Labor Department. It was well below the 335,000 economists had predicted.
In late afternoon trading in New York, the Dow Jones Industrial Average sank 1.36 per cent, the Standard & Poor's 500 Index dropped 1.34 per cent, while the Nasdaq Composite Index retreated 1.61 per cent.
In Europe, the Stoxx 600 Index finished the session with a 1.1 per cent decline from the previous close. France's CAC 40 fell 0.5 per cent, while Germany's DAX lost 0.7 per cent and the UK's FTSE 100 Index gave up 1.6 per cent.
"We got a fantastic jobless claims figure, which really should be a boost to the markets but instead it's having the opposite effect," Craig Erlam, a market analyst at Alpari UK in London, told Bloomberg News. "Tapering is really at the forefront of everyone's minds."
