2023 Global Investor 
Sub-Custody Survey


Welcome to the 2023 Global Investor/ISF sub-Custody survey.


The deadline for the sub custody survey has been extended to June 7th 2023


The purpose of this annual survey is to paint a picture of the world’s best sub-custodians. We ask market participants from broker-dealers to global custodians services to rate the performance of their sub-custodians (agent banks) in all countries in which they operate.


As a reminder, the performance of sub-custodians is rated separately in each country and results are published in the Summer 2023 issue of Global Investor magazine.


The survey opens on Monday 24 April 2023 and has been extended to Wednesday 7 June 2023.
