The Organization of the Petroleum Exporting Countries (OPEC) is unlikely to change its production ceiling when the group meets in June, according to Iran's oil minister Bijan Zanganeh.

"Lowering OPEC's production ceiling requires consensus between all members ... under current conditions it seems unlikely that the OPEC production ceiling will change," Mr Zanganeh was quoted as saying in local media.

Last month, Mr Zanganeh said the producing group should cut its target daily crude production by at least five per cent, or approximately 1.5 million barrels per day.

OPEC will meet on June 5. At its last meeting in November the group led by oil kingpin Saudi Arabia, decided against cutting output to defend its market share, resisting calls by some members such as Iran and Venezuela to reduce production to shore up prices.

Lower oil prices have caused pain for OPEC's less wealthy producers, including Iran. While the June 5 meeting in Vienna is likely to hear renewed demands from some OPEC members for a reduction in the amount of oil pumped, even officials from countries which favour a curb see it as unlikely.
