ISDA Margin Survey Year-End 2025

Why It Matters

The rise in margin and the shift toward non‑cash collateral tighten risk management and capital allocation for banks and dealers, signaling higher funding costs and greater reliance on government securities. This trend influences liquidity dynamics across the derivatives market and may affect pricing of cleared products.

Key Takeaways

• $1.6 trillion IM and VM collected, up 9.3% YoY
• IM posted to CCPs hit $423.5 billion, rising 8.7%
• Non‑cash collateral now 51.7% of total, cash at 48.3%
• Non‑cash makes up 89.8% of IM, 32.4% of VM
• Government securities dominate, with equities, ETFs and corporate bonds

Pulse Analysis

The International Swaps and Derivatives Association (ISDA) releases its annual margin survey to gauge how market participants meet post‑trade collateral obligations under the latest regulatory framework. By aggregating data from banks, asset managers, and clearing members, the survey offers a rare snapshot of the scale of initial margin (IM) and variation margin (VM) that underpins the non‑cleared derivatives market. The 2025 results show a pronounced expansion in total margin, reflecting both heightened trade volumes and stricter risk‑based requirements that have been phased in since the Basel III reforms.

A 9.3% year‑over‑year increase to $1.6 trillion in combined IM and VM signals that firms are allocating more capital to meet collateral calls, which can compress profit margins, especially for smaller dealers. The $423.5 billion of IM posted to central counterparties (CCPs) for cleared interest‑rate and credit‑default swap contracts underscores the growing reliance on clearing as a risk‑mitigation tool. This surge in posted margin translates into higher funding costs, prompting banks to reassess liquidity buffers and potentially pass expenses onto counterparties through wider spreads.

Perhaps the most striking shift is the composition of collateral. Non‑cash assets now constitute 51.7% of total collateral received, up from previous years, while cash fell to its lowest share at 48.3%. Government securities remain the backbone of non‑cash collateral, but the inclusion of equities, ETFs, and corporate bonds adds complexity to valuation and eligibility checks. Market participants must therefore enhance collateral management systems to handle diverse asset classes, a move that could drive demand for sophisticated analytics platforms and influence future regulatory guidance on acceptable collateral types.
