# Option settlement currency: why a dollar payoff can become a token amount

An option’s settlement currency determines the asset used to pay its result. Quotation currency, strike denomination and settlement currency can differ. Deribit’s documented inverse BTC and ETH options settle economically in the base coin; since 1 August 2026, in-the-money expiries pass through an inverse future before that future cash-settles.

## Key facts

- **Base coin:** Inverse BTC options settle economically in BTC; inverse ETH options in ETH. ([Inverse Options](https://support.deribit.com/api/v2/help_center/en-us/articles/31424939096093.json))
- **Two steps:** The cited post-August-2026 process creates a future then settles it. ([Inverse Options](https://support.deribit.com/api/v2/help_center/en-us/articles/31424939096093.json))
- **Exercise style:** European exercise occurs at expiry, while market trading can close a position earlier. ([Inverse Options](https://support.deribit.com/api/v2/help_center/en-us/articles/31424939096093.json))

## Translate the payoff into settlement units

Consider an illustrative one-BTC call with a 60,000-dollar strike and a 75,000-dollar delivery price. Its gross dollar-equivalent intrinsic value is 15,000, corresponding to 15,000 / 75,000 = 0.2 BTC before costs.

If the premium paid was 0.03 BTC, the difference is 0.17 BTC before fees. A fiat-currency performance calculation must also account for when and at what exchange rate each coin cash flow is valued.

## Two entries can represent one economic expiry

Under the cited current process, an in-the-money option becomes an inverse future at its strike and that future immediately settles in the base coin. Deribit states the net financial result matches the former direct settlement. An accounting import should not count the temporary future as a separate discretionary trade or double-count the payout.

## Check the instrument, not just the venue

These details concern inverse options. Other contracts can use different collateral, multipliers or settlement assets. Daily account settlement and final option expiry are also different events. Use the exact instrument specification and transaction log when reconciling what was paid.

## Questions

### Does a dollar strike mean I receive dollars?

No. It may define the payoff calculation while payment occurs in another asset.
