this is bond issued for nri
the main purpose of govt for introducing this bond to increase foreign exchange reserve
md company issuing this bond also not afraid of change in exchange rate
because these are redemed in rupee
in nutshell companies jo phle bond issue krti thi foreigners ko in $ terms unko iska redemption bhi $ me krna hota tha isliye in indian compnies ko foreighn exanchange fluction ka risk rhta tha
jbki rupee denomited bond me india company
ko paisa bomd ka rupee me redeem krna hota h so unka exchange fluctuation risk ab khatam ho gya....this rupee denominated bond concept was introduce by modi government.
