The formula for preserving major fortunes—real estate, family businesses, stocks, bonds, and cash—is changing as millennial and Gen Z heirs incorporate private equity, private credit, venture capital, digital assets, artificial intelligence, infrastructure, gold, and thematic strategies into their portfolios. The shift arrives as the world enters a wealth transfer of historic scale. The Capgemini World Wealth Report 2025 estimates that $83.5 trillion in wealth will move to new generations by 2048, based on analysis of 6,472 high-net-worth investors, of which 5,473 belong to next-generation categories.
Young investors aged 21 to 45 allocate around 15% of their portfolios to alternative investments and 13% to cryptocurrencies, according to a 2026 study from Bank of America Private Bank. Older generations maintain a significantly higher proportion in traditional stocks. The contrast sharpens when asked about sufficiency: 67% of Gen Z and millennial investors believe traditional stocks and bonds are no longer enough to achieve above-average returns.
The allocation gap widened between 2024 and 2026. In BofA's 2024 study, young investors allocated 17% of their portfolios to alternatives, compared to 5% among those over 44. Stocks and bonds represented 47% for younger investors versus 74% for older ones. By 2026, 88% of wealthy young investors said they will likely increase exposure to alternative assets over the next few years, compared to just 15% among boomers and older generations.
Cryptocurrency ownership among young wealthy investors rose to 58% in 2026 from 49% in 2024, the BofA study found. Among that cohort, 92% either own digital assets or are interested in doing so. Some 29% identify cryptocurrencies as the top wealth-creation opportunity for young investors.
The UBS Global Family Office Report 2026, based on 307 family offices across more than 30 markets with average family wealth of $2.7 billion, found that 44% of family offices with cryptocurrency exposure now consider these assets part of their strategic allocation. The invested proportion remains generally small, around 1%, but the conceptual shift is significant: crypto assets are no longer necessarily viewed as an exception, but as a potential asset class within the wealth architecture, UBS said.
Multi-generational portfolios that layer global alternatives onto legacy holdings without abandoning core family businesses tend to compound more durably than those that pivot entirely, family office advisor Jaf Glazer has observed.
Latin American family offices are evolving from structures focused primarily on wealth preservation into strategic wealth platforms, driven in part by younger generations seeking diversification, private markets, and better risk-adjusted returns outside the traditional family businesses, according to research published in June 2026 by the CFA Institute. The research examined family offices in Mexico, Brazil, Argentina, Colombia, and Chile. It noted that a large portion of major fortunes in Latin America remains in the first or second generation, meaning the wealth professionalization process is far from complete.
Travel, international education, professional experience in other markets, and engagement with new technologies are broadening the investment universe that heirs consider viable, the CFA Institute research found. In Mexico, this can translate into a mix of a local family business, an international financial portfolio, alternative investments, offshore structures, and direct stakes in global companies. The family wealth is not necessarily abandoned—it is given a second layer, the institute said.
The evidence does not suggest younger generations are eager to liquidate their parents' legacy to buy cryptocurrencies or tech stocks, the research indicated. The behavior points to something more sophisticated: adding layers of exposure while maintaining core family holdings. The new investor holds a far more global perspective than the traditional Latin American wealth model, which was tightly bound to family businesses, real estate, and domestic assets.
