Western Europe’s biggest crude producer said it won’t adjust spending to match any decline in oil revenue after a decision by OPEC to maintain supply levels triggered a slump in the price of oil. Norway’s government can’t redraft its budget because of what may turn out to be a temporary shock to prices, Finance Minister Siv Jensensaid yesterday in an e-mailed reply to questions. Instead, she signaled the central bank is better equipped to address such disruptions. “Monetary policy can react quickly when the outlook for the economy changes,” Jensen said. “We do not need to tighten expenses if a temporary business cycle pulls tax revenues down.” The Organization of Petroleum Exporting Countries, of which Norway isn’t a member, resisted calls to cut supply as oil sinks deeper into a bear market. The group maintained its collective production ceiling of 30 million barrels a day, Ali Al-Naimi, Saudi Arabia’s oil minister, said yesterday after OPEC’s 12 member-nations met in Vienna. Brent crude dropped as much as 8.4 percent in London, extending this year’s decline to 35 percent, and closed at about $72 a barrel. bloomberg
