<strong>Sixty percent of family offices globally are actively rebalancing portfolios in 2025, the highest rate in eleven years, according to combined reporting from CNBC's new Family Office Portfolio Tracker and jurisdictional custody data. The shift involves an estimated $2.1 trillion in assets under management repositioning across custody regimes, with Singapore, Switzerland, and the UAE absorbing the bulk of reallocated holdings. Offices that previously reviewed allocations annually are now doing so quarterly.

Public equities now represent the fastest-growing sleeve within family office portfolios, even as real estate holdings contract for the first time since 2012. The CNBC-Addepar tracker, launched this month with data from 89 reporting offices, shows public stock allocations rose 340 basis points year-over-year while direct real estate fell 220 basis points. This reversal reflects not enthusiasm for public markets but pragmatism: equities are liquid, portable, and easier to relocate across jurisdictions without triggering embedded capital gains or losing control structures. Real estate, by contrast, is immobile and increasingly taxed by left-leaning fiscal regimes in North America and Western Europe.

The custody migration matters because it signals a structural break in the geography of private wealth. Family offices are not fleeing taxation alone—they are hedging against asset freezes, compulsory disclosure regimes, and legal unpredictability. Offices managing over $500 million are splitting custody between at least two non-domestic jurisdictions, often using one for liquid assets and another for operating entities. Switzerland remains the anchor for European wealth, but Singapore has seen custody inflows rise 28% since Q4 2023, with the UAE close behind at 22%. Offices are also unbundling: separating investment management from custody, and custody from domicile, in ways that would have seemed paranoid five years ago.

This is not tax avoidance. It is tail-risk hedging for families who watched Russian oligarch assets frozen in 2022 and Canadian accounts locked during the trucker protests. The threat is not theoretical. Offices are modeling scenarios where democratic governments impose emergency capital controls or weaponize banking infrastructure against disfavored speech or industry exposure. The result is a quiet, orderly migration of $2.1 trillion across borders, executed by the same law firms and custodians who manage sovereign wealth.

Operators should watch three follow-on moves in Q2 and Q3. First, whether custody inflows into Singapore and the UAE plateau or accelerate—sustained acceleration would confirm this is generational, not cyclical. Second, whether family offices begin converting illiquid real estate into publicly traded REITs or real estate credit funds, a liquidity arbitrage that preserves sector exposure while enabling jurisdictional mobility. Third, whether the trend triggers regulatory backlash in high-tax jurisdictions, particularly if outflows exceed $100 billion from any single country by year-end. France and Canada are the likeliest flashpoints.

Fairbridge Asset Management's appearance at the Single Family Office Summit next month will test whether private credit can slow the real estate exodus. Short-duration, high-yield mortgage debt offers liquidity without surrendering real estate sector exposure, but only if the underlying collateral sits in jurisdictions offices still trust. That is the new constraint: not return, but rule of law.
