Episode notes
Perps Are Expiry-Free Cash-Settled Derivatives
- Perpetual futures (perps) are derivatives without expiry that provide continuous price exposure.
- They enable cash-settled trading where no underlying asset changes hands, boosting operational simplicity.
Enforcement Pushed Perps Offshore
- Perps often moved offshore because the CFTC alleged some offshore perps were swaps requiring DCM or SEF registration.
- That enforcement posture effectively pushed many trading venues and volume outside the U.S.
Crypto Fits Perps Better Than Hard Commodities
- Crypto is unusually well-suited to perps because no physical delivery is required and settlement is simple.
- That suitability has amplified perps' popularity but also regulators' concerns about leverage and speculation.
