LONDON (Reuters) -Oil prices rose on Friday after the International Energy Agency (IEA) said oil markets were tight, but were still heading for weekly losses on inflation worries and U.S.-Iran which could boost global supplies.
Brent crude futures rose 39 cents, or 0.4%, to $91.80 a barrel at 1015 GMT, while U.S. West Texas Intermediate crude gained 45 cents, or 0.5%, to $90.33 a barrel.
Prices are on track for their first weekly decline after seven consecutive weekly gains, however.
Saudi Arabia and the United Arab Emirates could help to calm volatile oil markets if they pumped more crude, the IEA said on Friday, adding that the OPEC+ alliance produced 900,000 barrels per day (bpd) below target in January.
