SP500 Eminin March 2018 Contract trades at premium in 10 Years for first time since before 2008, Any idea why and what impact it could have if any.

Can anybody explain. The SP500 emini march 2018 contract just started trading at a premium to the Sp500 Cash (+2 to 3 pts above) for the First time since before 2008 when it was trading as much as a 10 pt premium. Since 2008 it has been trading at a discount to the cash, as recently as the 2017 december contract. Do you see any significance going forward?

Thanks
