This level of standardisation is indeed what makes them so liquid and useful!

Oil is usually considered fungible.

Fungible is a word that sounds weird and I don’t get to say often enough.

  • To the first approximation, yes. But there are different standards for oil and they trade at different prices (e.g. Brent is more expensive than Urals).

  • Like commodity I suppose it also gets used to describe things that may not be 100% fungible but may be pretty close depending on the details and the circumstances.

  • If you are looking for more opportunities, recall that the difference between entities and value objects in domain-driven design is that value objects are fungible.
