DEGIRO uses a separate custodian entity to hold your assets, which means they are segregated from the assets of DEGIRO. The sole task of the custodian entity is to administer and safeguard your investments. By law it cannot perform any commercial activities. In the unlikely event that something is to happen to DEGIRO, your investments will not be treated as recoverable assets to DEGIRO's creditors, but will remain safeguarded by the custodian entity.
Yes. At DEGIRO you can rest assured that your investments are held securely.
