Is South Sudan Hyperinflating?

The Johns Hopkins Institute for Applied Economics, Global Health, and Study of Business Enterprise published in February 2017 a study titled "Is South Sudan Hyperinflating?" by Steve H. Hanke.

The author concluded that at the end of 2016 the annual (year over year) inflation rate was an elevated 390 percent. But South Sudan did not sustain a monthly inflation rate above 50 percent for 30 consecutive days and, thus, did not experience hyperinflation.
