OPEC said on Monday that demand for its crude will rise this year as the U.S. produces less and consumes more, in a report that appeared to point to benefits from the cartel’s strategy of letting oil prices slip to hurt rivals. In a monthly report on the market, the Organization of the Petroleum Exporting Countries reversed an earlier prediction that demand for its oil would decline by about 300,000 barrels a day. Now, the group says demand will be 29.2 million barrels a day, an increase of about 100,000 barrels a day compared with last year.
