What bank can perform a interbank transaction grey screen?

Interbank transactions typically occur between established financial institutions, and the term "grey screen" usually refers to a specific type of trading or transaction that is not publicly visible. Major banks that provide interbank services, such as JPMorgan Chase, Bank of America, and Citigroup, can facilitate these transactions. Additionally, specialized platforms like SWIFT may be used for secure interbank communications. It's essential to consult with the specific bank or financial institution for their capabilities regarding grey screen transactions.
