What the study found

A more positive central bank stance toward central bank digital currencies (CBDCs) is associated with significantly higher banks' net interest margin (NIM), which is the difference between interest income and interest expense.

Why the authors say this matters

The authors suggest this offers a new perspective on how sovereign digital currencies may be integrated with traditional financial intermediaries, and the findings indicate that CBDC development can affect banks' intermediary functions and profitability.

What the researchers tested

The researchers combined bank-level data from 43 countries from 2017 to 2022 with a central bank CBDC stance index built from official statements. They examined how CBDC development relates to bank profitability.

What worked and what didn't

The study found that a more positive CBDC stance by central banks can significantly improve bank NIM. The abstract says banks may respond to stronger deposit competition by raising deposit rates to keep funds, which can also lead to higher lending rates.

What to keep in mind

The available summary does not describe specific limitations, and the findings are reported at the level of bank data across 43 countries during 2017 to 2022.
