A wealth-management strategy case on Bank of Singapore's External Intermediaries (EAM) Desk, prepared for Investment Advisory & Wealth Management (FNCE 6011) in the SMU MAF. The analysis examines why BOS built a dedicated EAM desk, contrasts centralized versus decentralized service models, and diagnoses structural frictions — the retrocession conflict of interest, onboarding friction and a specialist skills gap. It recommends repositioning BOS as the "Asian Gateway" custodian, leveraging the OCBC ecosystem and BOS's Aa1 credit strength.
Why a dedicated EAM desk
The External Asset Manager business in Singapore has grown rapidly as Asia's first-generation wealth holders consolidate assets and plan succession, making EAMs a complementary, scalable source of custody, execution and related fees. Crucially, serving EAMs is not a core relationship-manager skill — it demands institutional-client capabilities rather than private-banking advisory. A centralized desk lets BOS deploy specialist talent, apply consistent risk control, achieve economies of scale and differentiate against established Swiss, US and European competitors.
Centralized versus decentralized service models
The decentralized model — individual relationship managers handling EAM accounts — preserves long-standing personal relationships and offers flexibility, but produces inconsistent service, a skills mismatch with institutional EAM needs and fragmented risk-control costs. The centralized desk delivers professional, standardized, institutional-grade support (bulk transactions, system integration, compliance handling) and scales better, at the cost of heavier resource investment. For BOS's long-term ambition to expand EAM business, the centralized model is the better fit.
Structural challenges
How EAMs still charge
Roughly 70% of EAMs operate on retrocessions — the volume-linked model that embeds the conflict of interest
Industry split cited in the case analysis.
The retrocession model — on which roughly 70% of EAMs still operate, versus about 30% on performance fees — embeds a conflict of interest because EAM income rises with trading volume rather than client outcomes, yet reforming it risks pushing EAMs to competitors. Onboarding friction arises when EAMs run their own KYC/AML but BOS applies separate standards, causing late-stage account rejections that erode trust. And servicing EAMs requires an institutional skill set the traditional relationship-manager track does not build.
The "Asian Gateway" recommendation
Rather than competing with Swiss banks on legacy, BOS should leverage its status as part of Southeast Asia's second-largest banking group — bundling OCBC's commercial banking, real-estate and trade finance and Great Eastern insurance into EAM-facing packages, formalizing a North Asia coverage desk, and elevating its Moody's Aa1 credit rating from marketing footnote to headline trust signal in a post-Credit Suisse environment.
Three supporting moves reinforce it: capturing the VCC and family-office wave (over 1,000 VCCs and ~2,000 single-family offices by end-2024) with a "VCC-Ready" custodian package, transitioning from retrocession toward transparent client-aligned pricing, and building an integrated EAM operating platform to remove onboarding friction.
