The VIX keeps going lower. Are we entering a new low-vol regime? While no one can say for sure, we can look to history as a guide. Ideally, we should look at the historical implied volatility, but VIX only started in 1990. Hence, I used realized volatility of the S&P 500 as a proxy since it goes back to the Great Depression.
I define high vol as anything above 20 and low vol as below 20. The Great Depression was indeed a scary period, spending most of the time in a high-volatility regime. But in modern times, we are in a low-volatility regime most of the time. However, we still get the occasional vol spikes that can rival the Great Depression.
