(ALGIERS, Algeria) — OPEC nations have reached a preliminary agreement to curb oil production for the first time since the global financial crisis eight years ago, immediately pushing up oil prices. Mohammed Bin Saleh Al-Sada, Qatar’s energy minister and current president of OPEC, announced the deal after several hours of talks Wednesday in the Algerian capital. The preliminary deal will limit output from the Organization of the Petroleum Exporting Countries to 32.5 million barrels per day, he said.
