This is a strange little bug that sometimes happens when Google is preparing for a big data push - and they often have a big change right before the holiday shopping system.
We've discussed the apparent back end problem a number of times in past years, but it does get less than interesting when all you want is your home page back in the rankings.
If this is what I think it is, and it's only been a few days - plus your website is traditionally strong and very "white hat" - then consider it a nasty Google bug, but one that will probably be straightened out on its own, and very soon.
If the problem is more than, say, 7-10 days old, then you may have a different issue going.

Simiar thing happend to my site, all homepage keywords all dropped (not gone)all inner pages are fine and ranking well and climbing but homepage keywords are position 32 from 5 and have not budged for 14days now.
I feel its a technical error google side (well hoping it is) and will come good soon.
