Foreign exchange derivative restrictions tighten on INR contracts, limiting non-deliverable positions, rebooking, and related-party dealings. Authorised Dealers are prohibited from offering non-deliverable derivative contracts involving INR to resident or non-resident users, while deliverable foreign exchange derivative contracts may continue only for hedging requirements and only where no offsetting non-deliverable positions are maintained. Rebooking of any cancelled foreign exchange derivative contract involving INR is barred, and no foreign exchange derivative contract involving INR may be undertaken with related parties. The instructions apply immediately until further review.
