Recently at a webinar organised by the IMF our deputy governor for the RBI stated
We (RBI) believe that CBDCs would actually be able to kill whatever little case there could be for private cryptocurrencies.
He is basically referring to Bitcoin, Ethereum and other cryptocurrency which they have termed as private cryptocurrency. You can read the complete article
hereI am not sure how he came to that conclusion? Wherein RBI uses its foreign reserves whenever the INR value falls to USD.
They do it by buying back INR with the USD they hold in foreign reserves, creating an artificial demand of INR.
INR does not hold any kind of demand in the international market as compared to USD. This same problem has been resolved to a great extent by China with their lending policy and also by introducing their international payment system similar to visa to the world. Internationally still only Chinese use that payment system know as Unionpay.
India has not created a market for its UPI payment system. It has started but it will take time to achieve it. In the meantime in crypto universe there are new invention every month. Therefore I feel the deputy governor or the government is too overconfident at the moment.
