US crude falls below $15 a barrel, down more than 20%

US crude fell about 20 percent to below $15 a barrel on Monday, its lowest level in about two decades, as a coronavirus-triggered collapse in demand eclipsed a deal to cut output. 

West Texas Intermediate, the US benchmark, fell 18.7 percent to $14.84 a barrel. 

Brent crude, the international benchmark, was off 1.5 percent at $27.64 a barrel.
