Kenneth Rogoff:

The fact that Libra will be pegged to the US dollar will give US authorities additional insight, because (at present) all dollar clearing must go through US-regulated entities. Still, given that Libra’s functionality can largely be duplicated with existing financial instruments, it is hard to see much fundamental demand for Libra except among those aiming to evade detection. Unless tech-sponsored currencies offer genuinely superior technology – and this is not at all obvious – they should be regulated in the same way as everyone else.

If nothing else, Libra has inspired many advanced-economy central banks to accelerate their programmes to provide broader-based retail digital currencies, and, one hopes, to strengthen their efforts to boost financial inclusion. But this battle is not simply over the profits from printing currency; ultimately, it is over the state’s ability to regulate and tax the economy in general, and over the US government’s ability to use the dollar’s global role to advance its international policy aims.
