That framing was so ingrained that I assumed it was the general case.</p> <p>When I started working on commodity derivatives, I encountered a different world. Many options are traded under futures-style margining. No premium changes hands at inception; instead, the option is margined daily like a futures contract. The convention tends to split along venue lines rather than by underlying. US exchanges are predominantly equity-style: options on WTI crude futures at the CME and options on corn and wheat futures at the CBOT all require an upfront premium. European venues lean the other way. Options on ICE Brent futures and options on EUA carbon futures at ICE Endex and EEX are both margined futures-style.</p>
