CME Clearing collects less margin for Eris SOFR than equivalent IRS, despite their equivalent cash flows, due to regulatory and default management differences between futures and swaps. Initial Margin covers the potential loss on a defaulted position prior to liquidation. Since futures positions from a default are generally liquidated in one day, compared with up to five days required for swap default auctions, less IM is required.
