I checked bloomberg few hours ago, to follow up on other volatility futures, and here are today's numbers:
Volume | Open Interest | |
VNKY (Nikkei) | 232 | 1091 |
INVIXN (Nifty) | 692 | 497* |
RTSVX (RTS) | 0 | 8 |
SPAVIX (S&P/ASX 200) | 0 | N/A |
VHSI (HSI) | 0 | 12 |
Unfortunately, it looks like most of the international volatility futures did not take off. VNKY looks solid, but volume still disappoints. India VIX is still in a honeymoon period; let's hope the volume stays.
* open interest as reported by NSE stands at 372750, but I believe that number is OI * 750 (contract size) I reported adjusted number for consistency.
