The United States exported 268,000 barrels per day (b/d) of crude oil in April (the latest data available from the U.S. Census Bureau), the highest level of exports in 15 years. Exports have increased sharply since the start of 2013 and have exceeded 200,000 b/d in five of the past six months. The increase in crude exports is largely the result of rising U.S. crude production, which was 8.2 million b/d in March.
