Recent Collaborations at GBM Securities

Recently, the firm strengthened its custody setup by working with BNY Pershing EMEA, a global provider of clearing and custody services for institutional clients. The collaboration is aimed at improving how client assets are held and overseen within GBM’s prime brokerage offering.

The new arrangement uses a Model B custody structure with a tri-party setup, where client assets are held directly with BNY Pershing EMEA rather than on GBM’s own balance sheet. This approach is intended to keep assets fully segregated.
