Possible? I fully expect to see it this summer.
If you havent already its time to prepare. You needed to be stocking up on food guns, ammo, basic household supplies like soap, papergoods, cleaning supplies, good sturdy clothes including extra socks, underwear and extra shoes and boots, a extra couple changes of oil and filters for your car, tools, things you buy everyday start buying two and put one up.
I think that we are at the very least in for a collapse much like that of Argentinas ( http://www.youtube.com/watch?v=7yerKMQc7-w&feature=grec_index), but as a armed society with a very large entitlement minded population our collapse will be much more violent and I see many many small business wiped out by flash mob looting, and large scale violence (look at what happened just this past Memorial Day weekend). I see what I call Pocket Pogroms taking place in many big Blue cities and if you arent Amish its going to get Reginald Denny bad for you very quickly.
For those who havent prepared and would like to start or for those that have and are just interested you may download my Preparedness Manual at:

As the LDS say When the emergency is upon us the time for preparedness has past.
Or as the bible says: A prudent man sees danger and takes refuge, but the simple keep going and suffer for it.
NIV Proverbs 22:3
I predict that 500 round blocks of .22LR will be the gold bars of the future.
