How Inverse Option Expiry Settles Through Futures

Summary

The document explains a change to inverse, coin-settled options expiry: an in-the-money option first creates a futures position at the option’s strike, and that future then settles to cash. Out-of-the-money options receive an expiry entry without a futures settlement. The exchange says the method leaves settlement currency and option profit or loss unchanged, while futures positions can net against existing positions before the future’s delivery fee is calculated.

Two BTC examples show how a call or put’s intrinsic value is represented through an inverse futures position and then paid in BTC. They illustrate the claimed equivalence between the old direct cash settlement and the new two-step process. The option delivery fee still applies; the generated futures position does not incur a second fee, though netting may reduce the future’s fee. The change is stated to take effect for inverse options expiring from August 1, 2026. API users and automated accounting systems should account for the temporary futures position. These are exchange explanations and examples, not independent verification of fee outcomes.

Key ideas

• An in-the-money inverse option creates a futures position at the option strike before the future settles to cash.
• The exchange states that the settlement currency and option profit or loss remain unchanged.
• The option delivery fee still applies, while netting may reduce or eliminate the futures delivery fee.
• API and accounting systems should recognize the temporary futures position during expiry processing.
