Widespread bank problems
There are reports of lots of weird things going on with Wells Fargo, Bank of America, Citibank, and credit union bankcards -- perhaps some VISA and Mastercards -- compromised accounts -- replacement cards being sent out -- people locked out of their accounts -- widespread problems in Canada and the US. The mainstream media has very little on the story. The banks are admitting that something is going on but aren't giving out much detail and the detail that is coming out isn't always consistent.

I'm not terribly worried about their ability to eventually straighten the whole thing out. Customers won't be loosing money -- just occasionally inconvenienced, I suspect.
