Oil declined amid ongoing concern US producers are undermining coordinated international efforts to lower a global glut.
"I think oil is reacting still to the steady rise in the US rig count and the realisation that momentum is building to the downside from the repositioning of speculative interests in the market," John Kilduff, partner at Again Capital in New York, told Reuters.
The recent slump in oil prices is weighing on the initial public offering of Source Energy Services, Canada's largest distributor of fracking sand. The Calgary-based company has cut the size of its IPO to about C$250 million (US$187 million) from C$300 million, according to a document obtained by Bloomberg.
It plans to sell shares at between C$13 to C$15 apiece, down from C$17 to C$20 a share previously, the document shows, Bloomberg reported.
In Europe, the Stoxx 600 Index ended the day with a 0.2 per cent decline from the previous close. France's CAC 40 Index slid 0.3 per cent, while Germany's DAX Index fell 0.4 per cent.
The UK's FTSE 100 Index squeezed out a 0.07 per cent advance.
