The Ukrainian hryvnia just made a new low against the U.S. dollar.

On Tuesday, one dollar bought 13.4 hyrvnias, with the hryvnia losing more than 4% against the dollar just today.

The latest drop in the currency comes amid reports that Russia is sending a convoy of 280 humanitarian aid trucks into Ukraine, according to Reuters.

This convoy comes amid warnings from Western nations that the help could be used, "as a pretext for an invasion."

This chart from Google Finance shows the severe depreciation in the value of the hryvnia against the dollar over the last month.
