The Organization of the Petroleum Exporting Countries raised its oil output in April to its highest level in five months, the U.S. government said.

The Energy Information Administration said in its monthly Short-Term Energy Outlook that the cartel boosted production to 30.21 million barrels a day from 29.93 million in March.

That is the highest output for the group since November, when output was 30.26 million barrels a day.

OPEC spare capacity fell to 2.6 million barrels a day--the lowest since December--from 2.7 million barrels a day.
