See how real-world supply shocks bend the oil futures curve into extreme shapes — and what those moments looked like.
When the curve breaks
The oil futures curve usually breathes within a comfortable range — a couple of dollars of contango or backwardation depending on supply and demand. But every once in a while something happens in the physical market that bends the curve into shapes that look like errors. They aren't errors. They're the curve doing its job in extreme conditions. Two episodes in the last decade tell the story.
April 2020 was the most extreme commodity event in modern history. COVID lockdowns crashed global oil demand by roughly 25 percent overnight. Storage facilities at Cushing, Oklahoma — the WTI delivery point — filled up. Holders of the expiring May 2020 contract who couldn't take physical delivery were trapped. On April 20, 2020, the front-month WTI contract closed at negative 37.63 dollars. Yes, negative. Buyers were paid to take the barrel because there was nowhere to put it. The curve, meanwhile, sat in supercontango — December 2020 contracts traded around 35 dollars while front-month sat below zero. The 1-12 month spread blew out beyond 50 dollars.
Less than two years later, the same curve produced the opposite extreme. When Russia invaded Ukraine in late February 2022, the global oil market faced an immediate fear of supply disruption from one of the world's three largest producers. Within weeks, WTI flipped into sharp backwardation. The prompt-to-1-year spread reached double-digit backwardation — front-month above 120 dollars while back-month contracts six to twelve months out traded well below. Refiners and traders were scrambling to lock in physical barrels not exposed to potential sanctions. Same curve, opposite shape, opposite signal. Both episodes showed the curve responding to physical reality before the financial headlines fully caught up.
Recap: shocks bend the curve. April 2020 was supercontango — storage full, demand gone, front-month negative. February 2022 was sharp backwardation — supply threat, scramble for physical, front-month at the top of the curve. Both episodes show the curve speaking before spot fully reacts.
Knowledge check
Answer before moving on.
1. Why did the front-month WTI contract close at negative $37.63 on April 20, 2020?
2. What does sharp backwardation in WTI in early 2022 tell you about how the market was pricing the Russia-Ukraine conflict?
