A narrow waterway off Singapore has become even more congested as oil-laden tankers wait out a slump in global fuel consumption that’s crimped demand and boosted the use of ships to store cargoes. About 60 clean fuel tankers are currently anchored along the busy strait, up from the usual 30-40 ships, according to Rahul Kapoor, head of commodity analytics and research at IHS Markit. Some vessels are being used to hoard fuel at sea as onshore tanks fill up. Others are probably parked, waiting to be redirected to any willing buyer across Asia and the world as the coronavirus pummels economies worldwide.

Ships filled with oil products including gasoline and jet fuel are moving from major refinery hubs such as South Korea and China due to a crash in domestic demand and swelling stockpiles. These tankers are finding their way to the Singapore Strait, where the glut is being compounded by offloading delays at the city state. Vessels currently have to wait about two weeks to discharge cargoes in Singapore, compared to the typical 4-5 days, according to shipbrokers and traders, leaving ships stranded in local waters.
