内容简介: We build models with an interest-bearing central bank digital currency (CBDC) to investigate whether the interest-bearing CBDC can lead to financial disintermediation. Our model of CBDC and banking captures a key feature of an intermediated CBDC system that idle CBDC can be converted into deposits. Higher interest rates on CBDC could increase bank lending and investment in a CBDC-only economy, because in the presence of idle liquidity, CBDC and bank deposits are complements. The higher return on CBDC encourages entrepreneurs to accumulate more CBDC and then deposit more. The interest rate on reserves and the reserve requirement ratio can be effective policy tools that affect bank lending and investment. Our quantitative analysis shows that a higher CBDC interest rate always promotes investment and its effect on lending depends on the type of banking equilibrium. We consider extensions where cash and interest-bearing CBDC can coexist. The coexistence may require the central bank to adjust
the CBDC interest rate or the interest rate on reserves. Our results suggest that the design of CBDC and banking are crucial for understanding the effects of CBDC on banking and the macroeconomy.
