How do flex options allow institutional players to customize strike parameters while avoiding OTC counterparty risk?
By Easy Money Scanner · Educational reference · Not investment advice
The short answer
FLEX options are exchange-listed contracts allowing customized strike prices, expiration dates, and exercise styles while still being cleared and guaranteed by OCC, eliminating the counterparty risk inherent in true OTC options.
How it works
Introduced by Cboe, FLEX options let institutions negotiate terms through a Request for Quote process but settle through standard OCC clearing, combining customization with centralized clearing guarantees.
An example
A pension fund wanting a six-month SPX option expiring on a specific non-standard date can request a FLEX contract rather than negotiating a bilateral OTC trade.
Risk & limitations
FLEX options generally require large minimum sizes and have thinner liquidity than standard listed series, making them impractical for typical retail trading.
