Physical vs Financial Settlement in Commodities

A speculative trader who is long crude oil futures for the price exposure has, in principle, agreed to take delivery of thousands of barrels of physical crude oil at a specific pipeline terminal if the contract is held to expiry. Almost nobody actually wants that. Understanding what actually happens at expiry — and why most traders never get anywhere near it — starts with the basic split between physically delivered and cash-settled contracts.

Two different endings

In a physically settled contract — WTI crude, most agricultural futures, many natural gas contracts — the seller who stays in the contract past a defined notice period must actually deliver the commodity (or a warehouse receipt for it) to a specified delivery point, and the buyer must accept it and pay the final settlement price. This is precisely why the overwhelming majority of speculative volume exits the position before expiry: hedge funds and retail traders roll their exposure into the next contract month well ahead of the delivery window, leaving only commercial players — refiners, grain elevators, actual producers — who genuinely want or can handle the physical commodity to stand for delivery.

In a cash-settled contract — most stock index futures, and increasingly some commodity contracts like certain natural gas hub products — the contract simply pays out the difference between the contract's final price and an official reference price (often an index or an average of trades in a settlement window) in cash. Nobody needs a warehouse, a pipeline connection, or a barge.

Worked example

A trader is long 5 WTI crude oil futures contracts (1,000 barrels each) with no intention of taking delivery. Two weeks before the contract's first notice day — the date after which the exchange can assign delivery obligations — the trader sells the expiring contracts and buys the equivalent quantity in the next contract month, a routine roll. If that same trader instead forgot to roll and held past first notice day, the exchange could match the position for delivery, obligating the trader to accept 5,000 barrels of physical crude at a Cushing, Oklahoma storage terminal — arranging tankage, transport, and quality inspection the trader has no infrastructure for, an outcome retail brokers typically prevent by forcibly closing such positions before notice day.

What this means in practice

Whether a contract is physical or cash-settled shapes its whole trading ecosystem: physically settled contracts stay tightly anchored to the real supply-and-demand and logistics of the underlying commodity near expiry (which is exactly why they are useful hedges for producers and consumers), while cash-settled contracts are cleaner for pure financial speculation because there is never a delivery-logistics tail risk to manage.
