Intransparente Margenberechnung und Fehlentscheidungen bei Positionsaufbau
Definition
Eurex Clearing Prisma (mandatory since 2015) calculates margin using SPAN® for derivatives and options with daily parameter updates. However, the Prisma Online Margin Calculator and Prisma Margin Estimator (PME) are batch-mode tools requiring manual input and interpretation. Traders cannot instantly see the margin impact of a trade until post-execution. This information gap causes: (1) traders to under-estimate leverage and breach risk limits; (2) risk managers to reject trades retroactively, causing deal friction; (3) portfolio concentration risk (e.g., illiquid commodity positions) to be discovered too late for efficient rebalancing. The concentration risk margin (CRM) charge, applied when liquidation periods exceed the 2-day regulatory minimum, is often hidden until end-of-day reporting.
Key Findings
- Financial Impact: €100,000–€500,000 annually (estimated from: 20–50 mis-sized positions per year × €5,000–€20,000 loss per position due to forced liquidation, corrective trading, or margin call penalties)
- Frequency: Daily (per trade executed); Monthly (risk limit reviews)
- Root Cause: Margin calculators (Prisma, PME) are not integrated into real-time pre-trade risk systems. Manual workflow: submit trade → wait for margin approval → execute → discover collateral shortfall.
