Cash holdings across family offices and ultra-high-net-worth investors have risen materially since 2022 — in some cases doubling as a share of total portfolio. The shift contradicts a generation of investment orthodoxy that emphasized full deployment of capital. The reasoning is worth understanding clearly.
What has changed
From 2008 through 2021, cash earned near-zero nominal yield and negative real yield. Holding cash was an explicit cost — the famous “cash is trash” period. The financial logic favored full investment, with leverage employed in many cases to amplify returns.
Since mid-2022, cash yields have normalized to 3-5% nominal in most major currencies. Real yields have turned positive for the first time in over a decade. The opportunity cost of holding cash has fallen materially.
This structural shift has changed the calculus. Holding 5-15% of a portfolio in cash is no longer an obvious cost; it is now a position with positive expected return.
The optionality argument
The primary reason sophisticated allocators have increased cash is not yield. It is optionality. Cash positions enable opportunistic deployment when market opportunities emerge. The investors who deployed capital in March 2020, in late 2008, or in 1974 had cash on hand. The investors who were fully invested at those moments missed the opportunity.
The pattern repeats across cycles: the highest-return entry points coincide with the moments when the broad market is stressed. Cash positions are the dry powder that allows allocators to act when others cannot.
The Buffett model
Warren Buffett’s Berkshire Hathaway has historically held cash positions ranging from 10% to over 30% of total assets. By mid-2025, the cash position exceeded $300 billion — the largest in absolute terms in company history.
The interpretation: Buffett has not found investment opportunities at acceptable valuations. The cash position is patient capital awaiting opportunities that meet his return thresholds. Berkshire has historically deployed cash at moments others have wished they could.
Families attempting to replicate this discipline face the same constraint: cash is uncomfortable to hold when others are making returns. The discipline requires accepting underperformance during bull markets in exchange for the option to outperform during corrections.
The volatility dampening
A second reason for higher cash positions is risk reduction. Portfolios with 5-15% cash have meaningfully lower volatility than fully invested portfolios. The smoother returns reduce the psychological pressure that drives behavioral errors.
For families in retirement or capital preservation modes, the volatility dampening is more valuable than the marginal returns sacrificed by holding cash.
The currency selection
Families holding meaningful cash positions face a currency allocation question. Cash held in dollars yields differently than cash held in euros, yen, or Swiss francs. The currency selection matters substantially.
Most sophisticated allocators hold cash in a basket of major currencies, weighted toward their primary consumption currency. The diversification reduces single-currency risk and provides multi-currency optionality.
The deployment discipline
The cash strategy fails without deployment discipline. Cash positions that grow without ever being deployed produce sub-optimal long-term returns. The investors who succeed have explicit criteria for when cash will be deployed and the discipline to act when those criteria are met.
The criteria vary by allocator but typically include: market drawdowns exceeding specified thresholds, valuation metrics reaching specified levels, or specific opportunities that meet return thresholds. The criteria must be defined in advance, not generated reactively.
The yield curve question
In a normal yield curve environment, cash earns less than short-term Treasuries, which earn less than longer-duration bonds. The yield pickup from extending duration is generally 50-150 basis points.
For cash positions intended to be deployed opportunistically, the duration extension is generally not worth the loss of liquidity. The 1-3 year Treasury position is a reasonable middle ground that captures most of the available yield while maintaining liquidity.
The implementation
For families building cash reserves, the recommended approach is to allocate 5-15% of total portfolio to cash and short-duration instruments, hold the position in a diversified mix of major currencies, define explicit deployment criteria in advance, and maintain the discipline to act when criteria are met.
The families that have followed this approach since 2022 have generally been positioned to capitalize on the volatility of 2023-2025. The families fully invested have generally not.
The forward view
The current cash yield environment may not persist. Central banks have begun easing cycles in major economies. The 3-5% nominal yields available in 2024 may compress materially by 2027.
For families considering cash strategy, the implementation should reflect the current environment but not assume it will continue. The optionality argument is independent of the yield environment; the yield is a contributor but not the primary justification.
