The ISDA Margin Survey analyzes the amount and composition of initial margin (IM) and variation margin (VM) received and posted for noncleared derivatives. The survey also reviews IM posted by all market participants to major central counterparties (CCPs) for their cleared interest rate derivatives (IRD) and credit default swap (CDS) transactions.

Leading derivatives market participants subject to the margin rules collected a total of $1.6 trillion of IM and VM at year-end 2025, representing a 9.3% increase from the previous year. This included $524.7 billion of IM and $1.0 trillion of VM. In addition, the survey finds that $423.5 billion of required IM was posted by all market participants to major CCPs for their cleared IRD and CDS transactions at the end of 2025, up by 8.7% compared to the end of 2024.

The share of non-cash collateral grew to 51.7% of total collateral received for non-cleared derivatives exposures, with the share of cash declining to its lowest level of 48.3% at year-end 2025. Non-cash collateral accounted for 89.8% of IM and 32.4% of VM, reflecting a continued shift in the composition of collateral for non-cleared derivatives.

Non-cash collateral remained concentrated in government securities, particularly US Treasury and other G-7 debt, alongside a meaningful allocation to equities and exchange-traded funds (ETFs) and corporate securities.
