				 Talks between Iran and six world powers to 
				settle a dispute around Tehran's nuclear programme extended 
				beyond a Tuesday deadline in the Swiss city of Lausanne. 
				 
				Brent crude for May delivery  was down 3 cents at $55.08 a 
				barrel by 1026 GMT, after reaching a session low of $54.70. 
				 
				U.S. crude for May delivery was trading 39 cents lower at $47.21 
				a barrel. 
				 
				Iranian senior nuclear negotiator, Abbas Araqchi, said that Iran 
				hoped to wrap up talks by Wednesday night. 
				 
				"We insist on lifting of financial and oil and banking sanctions 
				immediately ... for other sanctions we need to find a 
				framework," he told Iranian state television on Wednesday. 
				 
				French Foreign Minister Laurent Fabius was more cautions, saying 
				on Wednesday that talks between Iran and world powers were not 
				sufficiently advanced to ensure a quick conclusion. 
				 
				Talks had appeared to get bogged down after the United States 
				warned it was ready to abandon them altogether and Iran affirmed 
				its "nuclear rights", with officials cautioning any agreement 
				would probably be fragile and incomplete. 
				 
				"If you get an agreement, there is the likelihood of Iranian oil 
				being allowed to hit an already oversupplied oil market and 
				drive prices lower," said Michael Hewson, chief markets analyst 
				at CMC Markets. 
				 
				Iran currently produces around 2.8 million barrels per day 
				(bpd), according to a Reuters survey, although Western sanctions 
				limit exports to 1 million bpd. It keeps around 30 million 
				barrels of crude on its fleet of oil tankers ready to be sold if 
				possible. 
				 
				Higher OPEC supply also put pressure on oil prices, after a 
				Reuters survey showed the oil cartel increased supply in March 
				by 560,000 bpd, to its highest since October. Iraq's exports 
				rebounded after bad weather and Saudi Arabia pumped at close to 
				record rates. 
				 
				U.S. crude inventories rose for the 12th straight week by 5.2 
				million barrels, in the week to March 27, according to data from 
				the American Petroleum Institute. Official stockpile data is due 
				out on Wednesday at 1430 GMT.
