Asian Private Banker’s 2025 AUM League Tables point to an industry in the midst of an identity shift. On the surface, it was a record year, with Asia’s private banking AUM crossing US$4 trillion. But beneath the headline figure, the composition of growth tells a more complicated story, one where scale is expanding faster than structural change.

Discretionary portfolio management (DPM) remains central to this transition. It is widely regarded as the holy grail for private banks, offering recurring fees and stickier client relationships. Yet the data suggests a disconnect between growth and adoption.

Across Asia, DPM AUM grew strongly, but penetration rates as a share of total AUM remained largely flat. This raises an important question: is DPM genuinely becoming more embedded in client portfolios, or is growth being driven primarily by rising markets rather than behavioural change?

The divergence becomes clearer when looking at regional comparisons. Asian private banks continue to deliver strong DPM asset growth, but most still sit in relatively low penetration bands and remain outside the global top tier.

By contrast, more mature discretionary platforms in Europe and the US combine higher penetration with sustained growth in DPM assets. This points to a more structural form of adoption — shaped by earlier institutionalisation of managed portfolios in Europe and a more developed advisory-to-discretionary model in the US, rather than purely cyclical AUM expansion.

Sustainable investment (SI) shows a similar pattern, but with a more global footprint. Total SI assets have reached US$1.42 trillion, with European institutions continuing to anchor the space, and Asian and US private banks maintaining meaningful allocations. 

However, European players remain ahead in relative terms, reflecting their earlier integration of sustainability into core investment offerings rather than treating it as a product extension.

If DPM and SI highlight product evolution, the relationship manager (RM) data reveal how different operating models are scaling in practice. The industry shows a widening divergence in productivity models.

At one end are large platforms with extensive RM networks designed to cover a broad client base. This scale supports asset gathering but naturally dilutes AUM per RM. At the other end are more focused platforms that operate with smaller RM teams but generate significantly higher productivity per banker.

This raises a key question: is scale still an advantage in private banking, or is it becoming a structural drag on efficiency?

Taken together, the Asia AUM, DPM AUM, SI AUM, and RM productivity data point to a clear structural divergence in private banking models. The industry is no longer moving in a single direction. Instead, it is bifurcating into two distinct paths.

One is scale-driven, relying on broad RM networks and traditional coverage models to capture asset growth. The other is efficiency-driven, with smaller teams, higher discretionary penetration, and stronger productivity per banker.

The key question going forward is not whether the industry will continue to grow — it will — but which model will prove more sustainable: breadth and scale, or depth and discretion?
