SEBI Proposes Lower Z-Score for Commodity Derivatives SGF
Why in the news
After feedback that safeguards were too cautious and locked up capital, SEBI floated easier risk rules for commodity derivatives, centred on the Settlement Guarantee Fund (SGF).
Key facts
- Current stress test: 15 years of price history; extreme moves capped at Z-score 10.
- Proposal: lower the threshold to Z-score 5.
- SEBI’s reasoning: a Z-score of 10 captures very rare events and may overstate risk.
Key terms
- Z-score: distance of a price move from its historical average, in standard deviations; higher means rarer.
- SGF: a safety net run by clearing corporations to guarantee trade completion if participants default.
- SEBI regulates SGF in securities and commodity derivatives; exchanges’ clearing corporations (for example NSE, BSE) manage it.
Exam angle
- Regulator: SEBI; document: consultation paper.
- Change: Z-score 10 to 5.
- Related terms: clearing corporation, member default.
