Asian refiners shift towards cheaper Mideast oil, naphtha-trade; U.S. light oil exports to Asia only started 4 months ago. U.S. exports now going to Europe instead. An aggressive strategy by Mideast Gulf producers to exploit the lowest oil prices in five years to defend market share is showing signs of bearing fruit as U.S. crude exports to Asia grind to halt. Asian refineries have suspended imports of condensate, a light crude oil produced from the U.S. shale boom, just four months after they began in favour of cheaper Middle East grades, according to trade and industry sources. The suspension illustrates how competition between suppliers has heated up following a more than 40 percent decline in oil prices since June.
