Prime brokerage & Institutional Investment Services

Funds come in all sizes, but our brokerage services are designed to support most types of fund and to ensure efficient execution. Our network of global contacts also helps to support nascent funds as they begin the process of growth.


Our close relationship with a select group of clearer/custodians enables us to offer our customers all the benefits of prime brokerage that you would get from a large firm but the level of service you’d expect from a far smaller organisation. It also allows us to provide smaller clients with a range of services traditionally reserved for major institutions.

We offer a full suite of prime broker services including:

  • Custody and clearing of a broad range of financial instruments

  • Securities financing

  • Repo and margin finance

  • Trading and execution services

  • Custom structured trades and financing

  • Global electronic trading


Securities lending/repo

Our Portfolio Finance Team has decades of experience managing margins for some of the largest firms. With relationships all around the globe, we help customers mitigate risk and maximise returns through nuanced financing solutions.

Every financing goal requires a tailored solution. We seek to provide the maximum leverage available within a strong credit framework. We combine a personalised service with a full array of products so that we have a very solid understanding of what our clients need and how they can work more effectively.

Global Custody

All our accounts are segregated, at several major global custodians, where the assets are held in such a way that they are not susceptible to the claims of either our creditors or the sub-custodian creditors, should there ever be a credit event. Your assets are fully protected and safe.

Margin Finance

We provide leverage for extra trading in liquid securities, depending on your credit profile and collateral. Please note that this facility is only available for professional accounts.

Payment Services

We are an Authorised Payment Services Institution and can provide payment services to third parties, subject to our terms and conditions and careful scrutiny of any and all payments, as required by law and best business practices. There are substantial requirements placed on us due to the numerous laws governing money laundering, bribery and other corrupt practices. We are able to make payments in almost any currency.
