The design of the default option, the degree of member choice, and governance are three areas where Chile's AFP system and Australian superannuation have taken different paths. Rather than determining which model is better, the comparison helps identify what each system might usefully learn from the other.
Australia and Chile share a fundamental challenge: how to design a system that efficiently manages long-term retirement savings, balancing member choice with the need for investment strategies suited to each stage of life.
Yet the two systems have responded to this challenge in different ways.
In Australia, MySuper products were designed to offer a regulated, diversified default option for members who don't make an active investment choice. The framework sets specific requirements around investments, costs, benefits and governance. Within MySuper there are different investment structures, including single diversified-strategy products and lifecycle products, which adjust risk exposure as the member ages.
Chile, by contrast, developed a multifondos system that gives members greater scope to choose their retirement savings' risk exposure. When a member doesn't select a fund, regulation sets a default allocation tied to age. At the same time, members can choose among the available funds, within the constraints set by regulation.
This difference raises a relevant question for pension design: how far should the member decide their own risk exposure directly, and how much should rest on the design of the default option? In Australia, the system seeks to simplify this decision for those who don't actively choose; in Chile, the system preserves more room for the member to decide how to take on risk within their retirement savings.
Governance and consolidation
In Australia, superannuation funds are run by trustees subject to a prudential governance framework that sets responsibilities for their boards, including requirements around composition, capabilities, committees, conflict management and oversight of the fund's operations. This framework also places growing emphasis on trustees' accountability for member outcomes.
Over the past decade, Australia has also seen significant consolidation in its superannuation industry, with a marked reduction in the number of funds and growing market share for larger funds.
Chile presents a different structure. AFPs are special public companies operating within a regulated competitive framework, with specific obligations regarding fund administration and their members. Corporate governance structure is therefore not equivalent to that of Australian trustees.
Consolidation has increased the weight of larger funds, which have meaningful investment, risk-management and administrative capabilities. The Australian experience thus raises another question for Chile: how far can scale help improve efficiency and investment capability, and at what point does greater concentration require more robust governance and oversight mechanisms?
Scale can help build greater investment and management capability, but it also raises the importance of robust governance, effective controls and clear accountability mechanisms.
Chile, for its part, shows that a competitive structure among administrators can coexist with a relatively small number of participants, and with mechanisms designed to foster competition, including competition on fees and service.
This isn't necessarily a choice between concentration and competition. The relevant question is how to combine scale, efficiency, competition, and adequate protection of members' interests.
The real lesson: default design matters
Perhaps one of the biggest differences between the two systems lies in how they address member inertia.
In any pension system, a significant share of people will stay in whatever option they're assigned by default. For that reason, the design of that option can have significant consequences for long-term outcomes.
Australia has built much of its architecture around this reality. MySuper recognises that many members won't actively choose an investment strategy, and so sets a specific framework for the default option to meet certain standards.
Chile also recognises this reality through its age-linked default allocation mechanisms. However, the system preserves a multifondos architecture that allows members to actively participate in choosing their risk exposure.
The Australian experience suggests that the quality of the default can matter as much as the number of options available.
For Chile, this opens an interesting discussion about whether the pension system should continue to place significant emphasis on individual choice, or move toward more sophisticated defaults that incorporate factors like age, time to retirement, risk capacity and other relevant member characteristics.
What could Chile learn?
The Australian experience shouldn't be copied directly. The two systems developed under different institutions, labour markets and pension structures. Still, Australia offers at least three areas worth Chile continuing to watch.
First, default design. Having multiple alternatives doesn't guarantee better decisions. A well-designed default can matter especially for members who don't want to, or can't, actively engage with their investments.
Second, governance. As funds manage larger pools of savings and develop more sophisticated investment strategies, the demands on boards, risk management, conflicts of interest and accountability to members all increase.
Third, the relationship between scale and efficiency. Australian consolidation shows how larger funds can build meaningful capabilities and potentially benefit from economies of scale. But it also shows that greater concentration requires proportionally more robust governance and effective oversight mechanisms.
More than choosing a model — learning from each other
The comparison between Chile and Australia shouldn't be framed as a competition between two pension models.
Chile has developed an architecture that gives members a significant degree of choice within a multifondos system. Australia, for its part, has developed a model in which the default option and trustee accountability carry particular weight.
Both approaches have advantages and challenges.
The main lesson for Chile is perhaps not to have more or fewer funds, nor to copy MySuper directly. It's to ask what decisions the member should make, which ones the administrator should make, and how the system should be designed for when the member decides to make no decision at all.
Ultimately, a good pension system shouldn't be measured only by how many options it offers, but by its capacity to turn mandatory savings into better long-term retirement outcomes, with reasonable costs, sound governance, and investment decisions suited to those who depend on them.
