Undead ISDA
The status of every defunct ISDA master agreement, once all transactions have terminated, whether through the exigencies of a stressed close-out, or simply through the entropy and general lassitude of a modern life in which many former devotees of the ISDA creed grew bored, or adversely regulated, and gave up on swaps, once the last live ones have all rolled off.
For while you can terminate a Transaction under an ISDA Master Agreement the printed form does not envisage one terminating the master agreement itself. It has no general termination on notice provisions so, unless you and your counterparty specifically confect to agree one, a discarded ISDA arrangement will lie there mute, transfixed, plastered to the infinite like some ghostly figure frozen at the event horizon of a black hole for ever — surviving, indefinitely, some believe even beyond the expiry of the very entities whose trading relationship it once described.
