Oil falls on failed output freeze; Dow above 18,000
In Qatar, some 18 oil-exporting nations, including OPEC members, failed to agree to stabilise output at January levels until October 2016. A pact fell apart after Saudi Arabia demanded that Iran join in.
Crude oil ended well off the day's lows, however, with a strike in Kuwait slashing the country's oil output by more than half.
Brent crude LCOc1 settled down 19 cents, or 0.4 percent, at $42.91 a barrel, after falling $3 earlier in the session, while U.S. WTI crude CLc1 closed down 58 cents, or 1.4 percent, at $39.78 a barrel, after hitting $37.61 earlier.
