Tremor or full rupture?
Oil inventories about to spill over storage capacity, layoffs abound, gdp's imploding, eurobanks in distress, PIIGS puking, casino's crashing, Boeing probed, Saudis wanting to kill folk in Syria...and PM's rocketing...
A blip? An ouch? Something worse cometh?
I'd guess a preliminary act...a serious break cannot occur until a lot of exceptionally stupid people start doing stupendously idiotic actions to "fix" things!
Stir, add, mix...bake. Rinse/repeat often.
