Contango

A market condition where futures prices are higher than the current spot price — the normal state for storable commodities, reflecting storage costs and the time value of money.

Contango describes a futures curve that slopes upward: the further out the expiration date, the higher the futures price. This is the normal condition for storable commodities like oil, natural gas, gold, or corn. The higher futures price compensates sellers for the cost of storage, insurance, and financing the physical commodity until the delivery date. It also reflects the opportunity cost of capital — money tied up in inventory could be earning interest elsewhere.

For commodity ETF investors who own futures-based products (like USO for oil or UNG for natural gas), contango is a significant hidden cost. These funds must periodically "roll" their futures — selling expiring contracts and buying longer-dated ones. When the market is in contango, the fund is always selling cheaper and buying more expensive, continuously losing value through this roll process even if the spot commodity price stays flat. This roll cost erodes returns and is a primary reason commodity futures ETFs routinely underperform the spot commodity price over long periods.

Contango can sometimes be extreme. In April 2020, WTI crude oil futures briefly went negative (−$37/barrel) because storage capacity was completely exhausted — physically owning oil was a liability, not an asset. The front-month futures contract reflected the reality that nobody could store the barrels being delivered, creating an extraordinary and unforgettable example of what extreme contango looks like in crisis conditions.
