What Is an External Asset Manager (EAM)? The LPOA, Custody & Tripartite Model

An external asset manager (EAM) — also called an independent asset manager (IAM) or external wealth manager — is a firm regulated by the Monetary Authority of Singapore (MAS) that manages a client's investments while the client's assets remain held in the client's own name at a separate custodian bank. The client signs a Limited Power of Attorney (LPOA) authorising the EAM to trade the account, but the EAM never takes possession of the money. This three-party split — client, custodian bank, manager — is what defines the model and distinguishes it from a private bank that both holds and manages the money.

The structure exists to remove the central conflict in traditional private banking: when the institution that holds your money also earns from selling you products, advice and custody pull in opposite directions. An EAM is paid to manage, not to distribute, so it can use open architecture — selecting funds, banks and instruments across the market rather than a single house's shelf.

What does EAM actually mean?

EAM stands for External Asset Manager — "external" because the manager sits outside the bank that holds the assets. In Switzerland the same role is called an independent asset manager; in Asia you will hear EAM, IAM and external wealth manager (EWM) used interchangeably. The defining feature is always the same: the manager directs the portfolio, the bank holds it, and the client owns it. Singapore has become a fast-growing hub for the model, second to Switzerland, as more relationship managers leave private banks to set up independent shops.

How does the tripartite EAM model work?

Three parties, each with a distinct role:

• The client opens a custody account in their own name at a private bank and remains the legal owner of all assets.
• The custodian bank safekeeps the assets, executes trades, reports holdings and handles settlement — but does not decide the investment strategy.
• The EAM manages the portfolio under the LPOA: setting strategy, placing trades and reporting to the client, in exchange for a management fee.

Because the assets never leave the client's account, the client can see every position at the bank independently of the manager — a structural transparency that the all-in-one private-bank model cannot offer.

What is an LPOA and what does it allow?

The Limited Power of Attorney is the legal hinge of the whole arrangement. It grants the EAM authority to buy, sell and rebalance within the client's custody account, but it is deliberately limited: it does not allow the manager to withdraw cash, transfer assets to third parties, or change the account ownership. This is what keeps client money safe even though a third party is trading it. If you want a deeper view of how this differs from a bank's discretionary mandate, see our comparison of EAM vs private bank vs multi-family office.

Why do clients choose an EAM over a private bank?

Families typically move to an EAM for four reasons: independence (advice not tied to one bank's products), continuity (the relationship follows the manager, not the bank's staff turnover), multi-bank custody (assets spread across several banks but managed under one strategy), and alignment (fees for management, not commissions on product sales). The trade-off is that you are trusting a smaller, independent firm — so the manager's MAS licensing and track record matter.

A concrete example

Take a US$50 million family whose wealth sits in a discretionary mandate at a single private bank. They are frustrated that every product in the portfolio is the bank’s own, their relationship manager has changed twice in three years, and they cannot easily see how fees stack up. They appoint an EAM. The money does not move out of the banking system: the family opens custody accounts in their own name — say US$30M at their existing bank and US$20M at a second bank for diversification — and signs an LPOA at each, authorising the EAM to trade but not to withdraw. The EAM now manages the whole US$50M under one strategy across both banks, selecting funds and instruments from the open market rather than one house’s shelf, and bills a single management fee on AUM. The family keeps legal ownership, sees every position directly at each bank, and deals with one accountable manager who stays with them. That is the EAM model in practice: same custody safety, far more independence and transparency.

How does an EAM fit with a VCC?

An EAM that grows beyond a handful of accounts often outgrows pure LPOA management. The next step is to pool clients into a fund vehicle — most commonly a Singapore VCC structure — so each client sits in a ring-fenced sub-fund rather than a separate bank account. That move, and when it makes sense, is covered in our guide to launching an EAM VCC sub-fund platform. Families with serious scale also look at family office structures and the 13O/13U tax incentives.
