by Central bankers often argue that CBDC would increase the risk of bank runs. On his blog, JP Koning rejects this notion. After all, he retorts, during a confidence crisis bank customers would no longer have to queue to withdraw cash; lender of last resort support would be provided much more quickly; and “large” cash holders would continue to shift funds into treasury bills, not into CBDC. Koning writes: The general criticism here is that during a crisis, households and businesses will desperately shift their deposits into the ultimate risk-free asset: central bank money. Presumably when deposits were only redeemable in banknotes (as is currently the case) and one had to trudge to an ATM to get them, this afforded people time for sober contemplation, thus rendering runs less damaging.

But if small depositors can withdraw money from their accounts while in their pajamas, this makes banks more susceptible to sudden shifts in sentiment, goes the Carney critique.
I don’t buy it. … even in jurisdictions without deposit insurance, I still don’t think that shifts into digital currency in times of stress would exceed shifts into banknotes. A bank will quickly run out of banknotes during a panic as it meets client redemption requests, and will have to make arrangements with the central bank to get more cash. Thanks to the logistics of shipping cash, refilling the ATMs and tellers will take time. In the meantime a highly visible lineup will grow in front of the bank, exacerbating the original panic. Now imagine a world with digital currency. In the event of a panic, customer redemption requests will be instantaneously granted by the bank facing the run. But that same speed also works in favor of the bank, since a request to the central bank for a top-up of digital currency could be filled in just a few seconds. Since all depositors gets what they want when they want, no lineups are created. And so the viral nature of the panic is reduced.
But what about large depositors like corporations and the rich … ? During a crisis, won’t these sophisticated actors be more likely to pull uninsured funds from a bank, which have a small possibility of failure, and put them into risk-free central bank digital currency?
I disagree. In a traditional economy where banknotes circulate, CFOs and the rich don’t generally flee into paper money during a crisis, but into short-term t-bills. Paper money and t-bills are government-issued and thus have the same risk profile, t-bills having the advantage of paying positive interest whereas banknotes are barren. The rush out of deposits into t-bills is a digital one, since it only requires a few clicks of the button to effect. Likewise, in an economy where digital currency circulates, CFOs are unlikely to convert deposits into barren digital currency during stress, but will shift into t-bills. The upshot is that banks are not more susceptible to large deposit shifts thanks to the introduction of digital currency—they always were susceptible to digital bank runs thanks to the presence of short-term government debt.
Of course, depending on the type of CBDC, central banks might also choose to pay negative interest on CBDC in order to depress demand for it.
