The huge floating stockpile of crude oil kept on tankers amid a global supply glut is showing signs of shrinking, as traders struggle to make profits from the once highly lucrative storage play.
The volume being stored at sea has nearly halved from a peak of about 90 million barrels in April last year, according to ship broker ICAP. The total is expected to fall even further.
Some analysts have seized on the contraction as evidence that world oil balances are tightening and the surplus that built up during the recession, when energy demand in industrialized countries plummeted, is eroding.
