Same link says India's external debt to GDP ratio has been actually shrunk by 0.5% in 8 months despite external debt has been risen by few billions. Do you know what It means? It means that Our GDP growth has been much better than that of external debt. Which is what matters. Thanks for the link though.
Yes, it does fluctuate a little bit every other quarter but the overall debt is still heading towards the half-a-trillion dollar mark.
