We analyze the impact of banks intermediating CBDC on the interbank market. When banks increase their CBDC accounts by $1 they need $1 of reserves. Increasing CBDC usage drains reserves and may increase the interbank rate. The effect of CBDC remuneration is unclear: It makes CBDC a more attractive means to pay, thus reducing funding costs (reducing the drain in reserves) and encouraging investment (increasing the drain in reserves). A cap on CBDC holdings reduces interbank and commercial deposit rates, as banks require fewer deposits to buy reserves. Tiered remuneration does not provide additional benefits over a single (lower) rate.
