OREANDA-NEWS. Top global oil exporter Saudi Arabia will step in to cover any potential shortage arising from the Ukraine crisis, its oil minister said. Saudi Arabia, the only oil producer which can significantly alter output in response to changing demand, has in the past two years played the leading role in cushioning against supply disruptions from Libya, Nigeria, Iraq and South Sudan.

Russia, whose output has almost doubled over the past 15 years to more than Saudi Arabia's, has always pumped at full stretch. It has irked Riyadh several times by first agreeing to cooperate in output policy, but then doing very little to reduce production.

Riyadh feels the need to trumpet its unique supply role at a time of soaring U.S. output due to the shale boom, which has prompted politicians there to call for an end to the era of dependence on Middle East oil and the naval protection of sea routes in the region.

"We are willing to supply any shortage which may arise," said Saudi Oil Minister Ali al-Naimi. He said the kingdom's current output is around 9.6 million barrels per day (bpd), while it has a capacity of 12.5 million bpd.

Russia's annexation of Ukraine's Crimean peninsula and violence in eastern Ukraine have rattled oil markets, keeping benchmark Brent futures near USD 108 a barrel after hitting USD 112.39 on March 3, the highest this year.

Naimi said that both Saudi Arabia and the Organization of the Petroleum Exporting Countries would meet any additional demand for oil.

"Wherever demand is needed, we and other OPEC members will supply," he said.

Speaking on the sidelines of a conference in Seoul, Naimi also said USD 100 a barrel was a fair price for oil.

"One-hundred dollars is a fair price for everybody - consumers, producers, oil companies," he said. "It's a fair price. It's a good price."
