指数先物取引・国債先物取引（現金決済先物取引）・金利先物取引の決済方法 | 株式会社日本証券クリアリング機構

This page describes the settlement methods for index futures, Japanese government bond futures (cash-settled), and interest rate futures offered by Japan Securities Clearing Corporation. Index futures are settled through offsetting trades until the final trading day; if unsettled, they are cash-settled using the Special Quotation (SQ) and the settlement price difference. Bond and interest rate futures follow similar procedures, with offsetting trades as the primary method and cash settlement at expiration using the final settlement value. Mark-to-market settlement occurs between trade execution and final settlement.
