Hi,
@Muted. We apologize for the delayed response, but I wanted to provide some additional information.
The funds set aside in your cash-covered put reserve do continue to earn interest as long as your option contract remains open.
When you hold an open cash-covered put, sufficient cash to cover the exercisable value of the contract will be held in a “Cash-Covered Put Reserve” balance. This is not available to use for trading so long as the contract is open. During this time, your balances, specifically your “Cash available to trade” and “Cash available to withdraw,” will be reduced by the reserve amount; however, the funds will still be in your core position, and again, will continue to accrue interest.
