- Private tokenised monies that circulate as bearer instruments, like stablecoins, may entail departures in their relative exchange values away from par in violation of the “singleness of money”.

- Tokenised deposits may enable expanded functionality by building on the capacity of programmable ledgers to introduce contingent execution and composability of transactions.
