So as a global custodian, my service can only ever be as good as my sub custodian's offering. That means I'm gonna monitor my sub custodian. This involves onsite due diligence performed to verify accounting structure and reconciliation processes at the sub custodian are in line with my expectations. This also involves annual credit and country risk reviews. I want to make sure that my risk teams are comfortable that I'm offering services in Country X, and the credit exposure is fine in both Country X and any credit exposure to the sub custodian. I would assign a risk manager to each sub custodian bank to make sure there's not been a sudden downturn in their financial position. I would also look to be undertaking financial reviews and making sure that my risk team are constantly appraised of how the sub custodian is doing with various different regulatory matters.
