That is not suprising IMO. Interest rates are expected to rise by then, and we have a presidential election after a war near that time as well.Quote from Aaron:
Looking at the farthest out Nov contract, it looks like the market is saying the base level of the VIX should be about 20.85 (mid point of the bid/offer). With the nearer contracts and the cash VIX below this, we are temporarily in a more-quiet-than-usual market. We should expect volatility to pick up going forward...

My guess is that the spread has some relation to the treasury bond/note yield curve. How exactly I have no idea. One thing is for sure, it is not a linear relation.Quote from adonos:
Hi, I have some questions that are probably pretty stupid but hopefully someone will answer for me.
1. I guess this is trading at a premium to the VIX index. Why should the forward month be trading at a premium to the index and why would the back months have a larger premium? Is there any reason why the premium would be the value that it is?
Well, there is no direct underlying index to keep it "inline" that is tradeable. So index arbing I believe is not possible.2. Are there any arbitrage oportunities with these futures? What would one buy or sell if the futures got too far away from the index value?
