IMF’s Lagarde Open to CBDC

Summary:
At a conference in Singapore, IMF Managing Director Christine Lagarde has argued that [w]hile the case for digital currency is not universal, we should investigate it further, seriously, carefully and creatively. In her speech she emphasizes potential benefits related to financial inclusion; security and consumer protection; and privacy. (Privacy would be limited however.) She sees risks as well, including to innovation. But she de-emphasizes the notion of increased run risk which commentators often stress. What about the risk of bank runs? It exists. But consider that people run when they believe that cash withdraws are honored on a first-come-first-serve basis—the early bird gets the worm. Digital currency, instead, because it can be distributed much more easily than cash, could

[w]hile the case for digital currency is not universal, we should investigate it further, seriously, carefully and creatively.

What about the risk of bank runs? It exists. But consider that people run when they believe that cash withdraws are honored on a first-come-first-serve basis—the early bird gets the worm. Digital currency, instead, because it can be distributed much more easily than cash, could reassure even the person left lying on the couch!

In addition, if depositors are running to foreign assets, they will also shun the digital currency. And in many countries, there are already liquid and safe assets to run toward—think of mutual funds that only hold government bonds. So, the jury is still out on whether digital currencies would really upset financial stability.

She also refers to a recent IMF working paper on the subject.

The FT reports.

Almost all working papers on the subject of CBDC claim that the introduction of CBDC would change equilibrium outcomes. Very few papers carefully lay out the reasons; instead most papers make implicit assumptions that are not spelled out although they are crucial for the results. I have argued elsewhere (see this blog post) that the introduction of CBDC could leave equilibrium outcomes unchanged in a benchmark case, and with Markus Brunnermeier we have formally presented the argument.
