Why did oil prices go negative last week?

That was really quite a day on Monday. So, you saw WTI crude go into negative price territory. As you can imagine, the demand for oil has dropped dramatically. We're not driving as many cars. We're not flying as many airplanes. And so, that decline in demand means that oil is piling up in storage. That price drop also was likely exacerbated by an expiring futures contract and it basically capped off three straight weeks of losses in oil.
