The oil market plunged further on Tuesday on concerns over a collapse in demand as the pandemic leaves factories, cars and airplanes idled around the world. The extreme volatility in energy markets highlights investors' worries about the duration of the Coronavirus outbreak and its impact on the economy.

That is in turn weighing on financial markets more broadly, including stocks. The benchmark US oil contract was down $4.78 at just $15.65 per barrel on Tuesday, having traded as low as $11.79 a barrel at one point. The drop comes a day after the price of oil fell below zero on Monday, partly due to technical factors as traders shifted from one futures contract to another. The US oil contract for delivery in May settled at -$37.63 per barrel on Monday, an indication that investors don't want to be left holding oil at a time when storage facilities are almost full and demand is at its lowest since the mid-1990s. The tumult in the oil market reflects uncertainty over where the world economy will head as governments begin to loosen controls imposed to contain the coronavirus.
