Family offices are buying crypto to take less risk, not more

The ultra-wealthy are treating Bitcoin like a seatbelt for their portfolios, not a lottery ticket.

Five years ago, that sentence would have gotten you laughed out of a wealth management conference. Family offices are adding crypto because they want to reduce risk, according to a BNY Mellon survey covering the 2025–2026 period.

The bank found that 74% of family offices are either invested in or actively evaluating cryptocurrencies like Bitcoin and Ethereum. That is nearly double the 39% of single-family offices that reported similar interest in prior surveys.

The argument inside those family offices rests on correlation, or rather the lack of it. Bitcoin has historically shown a low correlation to equities and bonds. A portfolio construction principle says that adding an uncorrelated asset, even a volatile one, can smooth out returns over time.

BNY Mellon quantified the effect. Between April 2019 and March 2024, adding a 3% crypto allocation to a standard 60/40 stock-and-bond portfolio lifted cumulative returns from 33.3% to 52.9%, the bank said.

Actual allocations stay modest. Family offices typically dedicate 1% to 5% of total assets to digital assets. The more conservative offices cluster at the lower end. The composition of that crypto position leans heavily on Bitcoin. Between 70% and 80% of the crypto holdings sit in BTC as a core position, the survey found.

JPMorgan’s 2026 data tells the other side of the story. The bank found that 89% of family offices reported no digital asset investments at all. The main concerns were market volatility and regulatory uncertainty, JPMorgan said.

The two surveys look contradictory. BNY Mellon reports 74% exploring or invested. JPMorgan reports 89% untouched. The gap likely reflects different survey methodologies and the distinction between “exploring” and “actually deploying capital,” the reports said.

Spot Bitcoin ETFs have given traditional allocators a familiar wrapper for crypto exposure. Specialised custodial services have addressed the private-key security problem that kept many institutions on the sidelines, the BNY Mellon survey noted. Some family offices have anchored funds as large as $100 million specifically seeking market-neutral crypto strategies that harvest returns without taking directional bets on price, the bank said.

There is a risk worth watching. If family offices are mostly allocating to Bitcoin as a diversification tool based on its historical low correlation to equities, that thesis gets tested every time Bitcoin trades in lockstep with the Nasdaq during a market selloff. Correlation is not a fixed property. It tends to spike during the moments when diversification matters most, namely broad market stress events. If a future crisis reveals that Bitcoin correlates with everything else when it counts, the risk-reduction argument could unravel quickly.

The next real test of that thesis will come during the next 10% equity drawdown. Until then, the family office data shows Bitcoin’s role in wealth portfolios has shifted from speculation to portfolio construction.
