- CBDCs allow for direct digital payment rails that do not necessarily rely on intermediary banks or existing international systems like SWIFT. This can facilitate faster and potentially cheaper cross-border transactions without requiring conversion to a specific reserve currency like the US dollar for routing. - CBDCs can be designed with built-in rules or conditions, making them 'programmable'. This could include setting time limits for spending (expiry dates), restricting usage to specific goods or services, or triggering payments upon fulfillment of certain conditions.
