Impact of Central Bank Digital Currencies on Monetary Policy
Dr. Maria Chen

As central banks around the world explore Central Bank Digital Currencies (CBDCs), I believe we need to carefully consider how these new digital currencies might affect traditional monetary policy tools and transmission mechanisms.
Some key questions I'd like to discuss:
- How might CBDCs affect interest rate transmission in the economy?
- Could CBDCs provide central banks with new monetary policy tools?
- What are the implications for financial stability?
- How might CBDCs interact with existing payment systems?
Recent research from the BIS suggests that CBDCs could strengthen the transmission of policy rates to other interest rates in the economy. However, there are also concerns about potential disintermediation of commercial banks if CBDCs become too attractive as a store of value.
I'm particularly interested in hearing perspectives on how different CBDC design choices (interest-bearing vs. non-interest-bearing, limits on holdings, etc.) might influence monetary policy effectiveness.

Excellent topic, Dr. Chen. I think the interest rate transmission question is particularly important. If CBDCs are interest-bearing, central banks could directly influence a much broader segment of the economy than they currently do through the banking system.
This could potentially make monetary policy more effective, but it also raises questions about the role of commercial banks in the monetary transmission mechanism. If individuals and businesses can hold CBDCs directly, the traditional bank lending channel might be weakened.
The Bank of England has done some interesting modeling on this, suggesting that the impact depends heavily on CBDC design choices and adoption rates.

I'd like to add that CBDCs could potentially give central banks more granular data on money flows in the economy, which could improve policy decisions. However, this raises privacy concerns that need to be balanced carefully.
Regarding new monetary policy tools, programmable money features of CBDCs could theoretically allow for targeted monetary policy - for example, stimulus funds that can only be spent in certain sectors. This would be a significant departure from current blunt instruments.
The ECB's recent paper on their digital euro explores some of these possibilities while emphasizing privacy protections.

One aspect we should consider is the international dimension. CBDCs could potentially alter capital flows and exchange rate dynamics, especially if some major economies adopt them while others don't.
There's also the question of how CBDCs might affect the lower bound on interest rates. If physical cash remains available, there would still be a practical limit to how negative interest rates could go before people switch to cash. But the dynamics could change in interesting ways.
The BIS Innovation Hub is coordinating several multi-CBDC projects that are exploring these cross-border implications.
