If by “blockchain” you mean “Merkle tree ledger with any kind of mining”: the only reason to go with a blockchain design is trustlessness. In an environment where you can (or have to) trust one party with the operation of the whole thing, blockchains are an absurdly inefficient way of doing things.
If by “blockchain” you only meant the Merkle tree ledger part but without any kind of mining, well, that gets rid of the absurdly inefficient part, but it would still be a rather surprising design.

If you are using USD-CBDC as a reserve currency for your country you'd sure as hell want to make sure that the currencies aren't being changed from under your feet, as would banks sending money between each other.
