TOKYO (Reuters) - Asian shares edged lower as investors fretted about slowing global growth with crude oil prices sinking on worries about weakening world demand and oversupply.
U.S. crude futures dived 7 percent the previous day, suffering their biggest one-day loss in more than three years. The contracts last stood at $55.72 per barrel following a descent to $54.75 overnight, their lowest since November 2017.
OPEC warned on Tuesday that a supply glut could emerge in 2019 as the world economy slows and rivals increase production more quickly than expected.
The concerns about global growth pushed MSCI's broadest index of Asia-Pacific shares outside Japan down 0.07 percent.
Australian stocks <.AXJO> fell 0.5 percent, South Korea's KOSPI lost 0.2 percent and Japan's Nikkei <.N225> added 0.3 percent.
