- Regulatory Variation Margin (VM) CSAs mandate zero threshold (Threshold = $0), Minimum Transfer Amounts (MTA) ≤ $500,000, and same-day (T+0) or T+1 eligible collateral settlement.
- Uncleared Margin Rules (UMR) Initial Margin must be held in bankruptcy-remote third-party custodial accounts with a absolute prohibition on rehypothecation.

Frequently Asked Questions (FAQSchema Verified)
How did the ISDA 2002 Master Agreement replace Market Quotation and Loss from the 1992 ISDA?▼
The 2002 ISDA introduced the unified "Close-Out Amount" standard in Section 6(e), allowing the Determining Party to incorporate dealer quotes, internal pricing models, and mid-market funding/credit spreads when dealer market quotations are illiquid during systemic crises.
Why cannot Initial Margin posted under Uncleared Margin Rules (UMR) be rehypothecated?▼
BCBS-IOSCO rules mandate that regulatory Initial Margin protects against counterparty default replacement cost during a 10-day close-out period; therefore, it must be segregated on a gross basis with an independent custodian so it returns intact if the secured party defaults.
