What the PPLI.com rating of Santander International considers

We look at the areas below, which matter to a family deciding where to keep its assets, and weigh them together with what clients tell us and the service they get. Retail products, branches and apps play no part. The public sources we used are listed at the foot of the page.
Conduct and enforcement
What regulators, prosecutors and courts have concluded about this licence holder in recent years.
Protection of client assets
Whether custody assets are ring-fenced by law in the booking centre, whether deposits are protected, and whether the custody terms can be read before signing.
Service for complex families
The breadth of private banking services the bank publishes for this booking unit, including work with external managers and family offices.
Cost transparency
Whether a prospective client can see the tariff and the bank's policy on third party payments before asking.
Ownership and control
