The largest intergenerational transfer of wealth in history is well underway, raising a question that extends far beyond who will receive the assets: what will happen to the wealth once it changes hands?
The answer will have profound implications for families, family businesses, and particularly the wealth management industry. According to Capgemini’s World Wealth Report 2025, up to $83.5 trillion in wealth is projected to be transferred to new generations by 2048. This figure encompasses Generation X, Millennials, and Gen Z, though the latter two generations will hold a growing share of the transferred wealth.
However, the sheer volume of resources involved turns wealth succession into one of the central challenges of the coming decades. It is not merely a matter of distributing assets among heirs, but of determining how to preserve them, who will hold control, how decisions will be made, and what portion of the wealth will continue to generate value for subsequent generations.
This shift also represents a major transformation for wealth managers. The traditional financial advisor, focused primarily on product selection and portfolio management, faces the need to evolve into an interlocutor capable of guiding families through governance, taxation, ownership structures, investments, and intergenerational agreements.
Mexico: A New Wave of Financial Wealth
Mexico stands among the emerging markets poised to benefit from this transformation. Boston Consulting Group’s (BCG) Global Wealth Report 2026 estimates that the country could add around $550 billion in financial wealth between 2025 and 2030, ranking second only to India and Brazil among top emerging-market generators of new financial wealth. In another projection within the same report, BCG forecasts roughly $600 billion in total Mexican wealth growth by 2030, depending on the metric used.
The distinction is important: the $550 billion refers to the projected increase in financial wealth, not the absolute size of the Mexican investable asset market. Even so, the figure illustrates the magnitude of the opportunity opening up for banks, asset managers, family offices, independent advisors, and other participants in the wealth management ecosystem.
BCG specifically identifies the client segment holding between $250,000 and $5 million in financial assets as one of the areas with the highest potential for wealth managers in emerging markets. These are clients who have outgrown traditional deposit products but do not always receive the level of service that private banking reserves for ultra-high-net-worth individuals.
This expansion of financial wealth coincides with a generational transition that will add complexity to the relationship between families and their advisors.
Inheriting No Longer Simply Means Receiving
Wealth succession has historically been understood as a relatively straightforward process: determining who inherits, how assets are distributed, and what legal and tax obligations apply.
That model is proving insufficient. BCG notes that today’s families hold assets distributed across various asset classes and jurisdictions, while family members are increasingly dispersed geographically, with differing professional and business interests. As a result, succession ceases to be a single event and becomes an ongoing process of estate architecture that can span years.
The friction can be especially evident in family businesses. For the founder, the company often simultaneously represents ownership, control, identity, and personal wealth. For successors, however, that same bond does not necessarily exist. Some may wish to continue running the business; others may prefer to sell, diversify, or use a portion of the wealth to pursue new ventures.
Consequently, dividing wealth into equal shares does not guarantee that its value will be preserved. A distribution that appears equitable among heirs can end up fragmenting ownership, weakening control, or complicating decision-making—especially when family businesses, illiquid assets, or cross-border investments are involved.
From Portfolio Manager to Wealth Architect
In this new environment, the role of the financial advisor is also changing. BCG suggests that the wealth managers best prepared for the next stage must evolve from product providers into wealth system architects. Their role will need to integrate ownership and control mechanisms, family governance structures, cross-border tax and legal considerations, and long-term objectives.
The difference is substantial: managing a portfolio involves deciding how much to invest in equities, fixed income, alternative assets, or cash. Managing a succession involves answering far more complex questions: who gets to decide on those assets, under what rules, to what ends, and how the next generation will be prepared to manage them.
Through this process, tools traditionally associated with family offices and major family enterprises are coming to the forefront: family constitutions, family councils, formal governance frameworks, the separation of ownership, control, and management, financial education for heirs, and early preparation of the next generation.
Advisory work is also acquiring an interpersonal dimension. Conversations around leadership, fairness, control, and the purpose of family wealth can be difficult. An advisor can serve as a neutral third party capable of facilitating agreements and translating family goals into concrete wealth structures.
BCG emphasizes that elements such as family values, relationships, reputation, and institutional knowledge are also part of the estate, yet they are not transferred automatically. To survive the founding generation, they must be transmitted through education, mentorship, gradual involvement in decision-making, and early exposure to family governance structures.
Therein lies one of the primary risks of the great wealth transfer: capital passing from one generation to the next faster than the capacity to manage it.
Furthermore, the new generation enters this process with a different approach to investing. Capgemini’s research shows that younger investors have greater exposure to alternative assets than previous generations, signaling shifts in portfolio composition as wealth moves across hands.
For asset managers, this means succession cannot be treated solely as a preservation issue. It will also be necessary to understand what the new owners intend to do with the capital they receive.
This phenomenon presents a major opportunity for the financial industry. Wealth growth in Mexico and other emerging markets, combined with intergenerational transfer, can expand the potential client base for private banks, independent managers, family offices, and investment platforms.
Yet it also raises expectations: clients receiving the wealth will not necessarily remain with the same manager who served their parents. The transfer of assets can easily turn into a transfer of financial relationships. Institutions that engage with the next generation before the succession takes place will have a significantly higher chance of retaining those assets.
Nor will competition be limited to traditional banks. Family offices, independent advisors, and digital platforms are expanding the range of alternatives available to investors, while differentiation begins to shift from product access to the ability to deliver comprehensive wealth solutions.
The great wealth transfer will therefore not be merely a demographic or familial event. It will also represent one of the largest redistributions of client relationships and assets in the history of the wealth management industry.
The challenge for families will be ensuring that their wealth outlasts its founders. For advisors, it will be proving they can offer more than just money management. In the coming decades, preserving a fortune will depend less on who inherits it than on how well the structure built to support it is designed.
