In my opinion the reason is very high amount of ICOs these days that run on Ethereum, and especially the EOS ICO that runs already for half a year and will end up by the end of the month. The amount of traffic that all these ICOs generate is really significant, which consequently affects the gas prices. I think it's one of the reasons that more alternatives to Ethereum platform will soon emerge.

This is a very plausible explanation. I remember that gas prices went up last December too when crypto kitties was utilizing the ethereum blockchain. I wonder how long this gas price hike will last
