We discuss the advantages of adopting government-issued digital currencies and a supranational digital iCurrency. This will get rid of paper money, a ubiquitous medium for spreading germs, as highlighted by the recent coronavirus outbreak. We set forth three policy recommendations for adapting mobile devices as new digital wallets, regulatory oversight of sovereign digital currencies, and a supranational digital iCurrency. We also argue that the USA should reevaluate its “exorbitant privilege and exorbitant duty” in light of the financial meltdown from the coronavirus outbreak.

We discuss the idea of a purely algorithmic universal world iCurrency in light of recent developments, including Libra. We analyze the Libra proposal, including the stability and volatility aspects, and discuss various issues to be addressed. For example, one cannot expect a cryptocurrency such as Libra to trade in a narrow band without a robust monetary policy. A technical appendix (available online) provides a detailed mathematical description of the (crypto) FX rate dynamics in target zones.

A large number of decentralized cryptocurrencies has emerged since the inception of Bitcoin in 2009, with a total market size exceeding $170bn. Recent reports suggest that Russia will issue its government-backed cryptocurrency, CryptoRuble, in the middle of 2019. Russia’s primary goal in issuing a government cryptocurrency is to free its monetary system from the controls exerted by the Federal Reserve and their allied central banks. Government-issued cryptocurrencies will increase: Large sovereign states have the technological know-how and means to do this, but small and/or developing countries may be forced to outsource issuance of their government-backed cryptocurrencies to larger states.
