So an ocean or multicurrency pool or an optimized cross currency pool must have the following in place. The pooling must be permitted from a legal perspective, so all documentation must have been agreed with cross guarantees, et cetera. The banker must have got an agreement from the central bank that they're able to report pooled balances separately from regulatory capital reporting perspective. If the bank does not obtain this central bank agreement, then it runs the risk of paying the client interest on cash that actually the bank is gonna be paying interest on details of the pool and documentation must be kept by both the bank and the client. As this is an audit trail of what was agreed, the bank selected to be able to do this by the corporate must have plentiful supply of all the currencies that are included within the pool. The best thing to do with a pool, particularly with US dollars, is to have it the the cash follows the sun. So for example, in Asia, at the end of the day, US dollar positions could be cash concentrated to a pool in London, for example, and then at the end of the London day, those US dollars if required, could be cash concentrated to say New York where you could be obtaining your overnight interest. Of course, all of these arrangements need to be agreed with the central bank and need to adhere to both Basel III and CRD IV.
