The most notable event in history where oil prices dropped to zero (and even went negative) occurred on April 20, 2020.
On that day, the front-month West Texas Intermediate (WTI) crude oil futures contract (the main U.S. oil benchmark) plunged into negative territory for the first time since trading began in 1983. It settled at −$37.63 per barrel, with lows reported around −$40 or lower in some accounts.
This meant that sellers (producers or traders) were effectively paying buyers to take the oil off their hands, rather than receiving money for it.
The collapse was driven by the pandemic, which caused a sudden and severe drop in global oil demand (as travel, flights, and economic activity ground to a halt). At the same time:
Oil production continued at high levels initially.
Storage facilities, especially at the key Cushing, Oklahoma hub, were rapidly filling up (reaching ~83% capacity).
Traders holding expiring May 2020 futures contracts faced the risk of having to take physical delivery of oil they had nowhere to store
This created a "hot potato" situation where people paid to avoid taking delivery. The next day (April 21), prices rebounded above zero (settling around +$1–$2 for the May contract), but the event highlighted extreme market stress. Brent crude (the global benchmark) did not go negative but hit a multi-decade low of about $9.12 per barrel around the same time.
Historical Context
First time ever for WTI futures to go negative.
No prior instances in modern recorded oil futures trading history where prices reached zero or below.
Other major oil price crashes have occurred (e.g., in the 1980s, 1990s, 2008–2009, and 2014–2016), but prices stayed positive—though they sometimes fell very low
This 2020 event remains a unique anomaly tied to the pandemic-induced demand shock and storage constraints. If you're thinking of spot/physical prices (not futures), they didn't literally go negative for end consumers, but the futures collapse was the headline event.
