What is trade compression and why has it become so important in OTC derivatives markets?
I keep seeing references to 'trade compression' and 'portfolio compression' in the FRM Part I material on OTC markets. How does it work, what are the benefits, and is it mandatory?
Trade compression (also called portfolio compression) is the process of terminating redundant or offsetting derivatives trades and replacing them with a smaller number of trades that maintain the same net risk profile. It's become a critical tool for managing operational complexity and capital efficiency.
How It Works
Suppose three banks — Ashbury, Belmont, and Cortland — have the following interest rate swaps between them:
- Ashbury pays Belmont $100M fixed (receives floating)
- Belmont pays Cortland $80M fixed (receives floating)
- Cortland pays Ashbury $60M fixed (receives floating)
After compression, the circular flows are netted:
- Ashbury pays Belmont $20M fixed (net of $100M - $80M through the chain)
- Belmont pays Cortland $20M fixed
- Cortland's obligation to Ashbury is eliminated
Before: 3 trades, $240M gross notional
After: 2 trades, $40M gross notional — an 83% reduction.
Types of Compression
| Type | Description | Example |
|---|---|---|
| Bilateral | Two parties net offsetting trades | Two matching swaps cancelled |
| Multilateral | Multiple parties compress in a coordinated cycle | TriOptima triReduce runs |
| CCP-initiated | CCP compresses cleared trades automatically | LCH SwapClear compression |
Why It Matters
- Capital relief: Under SA-CCR, gross notional feeds into the exposure calculation. Fewer trades = lower exposure = less capital.
- Operational risk reduction: Fewer trades means fewer settlements, fewer margin disputes, fewer reconciliation breaks.
- Systemic risk: Lower gross notional reduces interconnectedness. Global OTC notional has been reduced by hundreds of trillions through compression.
- Leverage ratio: For G-SIBs, the leverage ratio denominator includes derivatives exposure. Compression directly improves this ratio.
Regulatory Push
EMIR Article 14 requires financial counterparties with 500+ non-centrally-cleared OTC derivatives to have procedures for portfolio compression. In the US, CFTC rules similarly encourage regular compression cycles.
Example: Thornbury Bank participates in a quarterly multilateral compression run with TriOptima. Before the run, it has 12,400 interest rate swaps with $890B gross notional. After compression, it has 6,800 swaps with $340B notional — a 45% reduction in trade count and 62% reduction in notional, saving approximately $180M in risk-weighted assets.
