The Russian Ruble Is Getting Slammed

The Russian ruble is getting slammed. It's down 0.6% against the dollar today.

In the last two months, the ruble has fallen more than 8%, with 1 U.S. dollar currently buying nearly 37 rubles, up from about 34 in late June.

The latest decline in the ruble comes after Russian troops appeared to make additional advances in Ukraine, which Ukrainian president Petro Poroshenko called a "sharp aggravation of the situation in Donetsk region."

Following this move on Thursday, geopolitical expert Ian Bremmer of Eurasia Group tweeted, "Russia, Ukraine now at war."
