Watch Art Cashin: How market sees global unrest
Cashin, UBS' director of floor operations at the NYSE, told CNBC's Bob Pisani around midday, "The U.S. is going through a period of intervention fatigue. There's no will to get involved in anything else at this time, coming out of two recent wars. Yes, it should be watched, because if it begins to slip into things like the financial industry, if there are runs of money out of any of these countries then it would be of a concern."
But for now, he said, "They're going to look past it because they don't believe the U.S. is going to get physically involved in it."
