What is really interesting is that while VIX and VSTOXX rose this week, other volatility indexes around the world fell. I did not have the time for thorough data analysis, but NSE India VIX index made an all-time low, closing at 16.74 on Fri, link. Keep in mind that the index was in existence for a relatively short time. I was able to put together two charts of Citi Asian volatility indexes (that have longer history than India VIX) and VIX.
Over the past five years most of Asian markets had higher implied volatility than the VIX.
