Dangote refinery, Africa’s largest, has increased export of petrol and urea to African countries hit by supply disruptions caused by the Iran war, its owner, Aliko Dangote said yesterday.

Dangote said the refinery, operating at its maximum capacity of 650,000 barrels a day, had helped cushion the effect of the crisis both in Nigeria and across the continent, a Reuters report said.

“What I can do is assure Nigerians … and most of West Africa, Central Africa, and East Africa, we have the capacity to supply them,” Dangote said during a tour of the refinery on the edge of commercial capital Lagos.

He said the facility had shipped some 17 cargoes of petrol to other African nations and exports of urea fertiliser had also recently risen, as buyers sought alternative sources of supply.

“In the last couple of days, we’ve been looking to mostly African countries, which we were not doing before,” he said, referring to the fertiliser shipments, without giving figures, Reuters added.

The refinery has capacity to produce up to three million metric tons of urea annually, most of ⁠which is typically exported to the United States and South America, officials say.

Fuel prices in oil-producing Nigeria have reached record-high levels, industry figures show, as maximum output from Dangote refinery has not offset the effect of high crude prices.

Dangote said the refinery hoped to get more crude cargoes priced in local currency to help curb fuel costs.

Two trade sources and a refinery official told Reuters last week that state oil firm Nigerian National Petroleum Company Limited (NNPC) was allocating seven May cargoes for Dangote refinery, up from five in previous months.

Meanwhile, oil prices inched up in choppy trade on Monday, as investors awaited clarity on the status of talks between the U.S. and Iran and remained wary about sustained supply losses due to shipping disruptions.

Brent crude futures were up 0.1 per cent to $109.13 a barrel, even as U.S. West Texas Intermediate (WTI) crude futures were trading up 0.69 per cent, or 77 cents, at $112.31 per barrel.

U.S. and Iran received the framework of a plan to end hostilities, but Iran rejected immediately reopening the Strait ⁠of Hormuz, after President Donald Trump threatened to rain “hell” on Tehran if it did not make a deal by the end of Tuesday.

Iran also said it had formulated its positions and demands in response to recent ceasefire proposals conveyed via intermediaries. The Strait of Hormuz, which carries oil and petroleum products from Iraq, Saudi Arabia, Qatar, Kuwait and the United Arab Emirates, remains largely closed due to Iranian attacks on shipping after the war began on February 28.

Some vessels, however, including an Omani-operated tanker, a French-owned container ship, and a Japanese-owned gas carrier, have passed through the Strait of Hormuz since Thursday, shipping data showed, reflecting Iran’s policy to allow passage for vessels from countries it deems more friendly, Reuters reported.

The Middle East supply disruptions have led to refiners seeking alternative sources for crude, particularly for physical cargoes in the U.S. and Britain’s North Sea. Spot premiums for U.S. West Texas Intermediate crude has jumped to all-time highs on competition between Asian and European refiners.

On Sunday, OPEC+ agreed to a modest rise of 206,000 barrels per day for May. Saudi Arabia also set the official selling price of May Arab Light crude oil to Asia at a record premium of $19.50 a barrel, above the Oman/Dubai average, an increase of $17 from the previous month, Aramco said.
