- 38% of HNWIs now hold more cash than three years ago, with cash making up an average of 19% of total wealth.
- Likewise, 41% of UK small and mid-sized businesses have increased cash reserves, with businesses now holding an average of nine months’ working capital in cash.
Cash is taking on a far more prominent role in high-net-worth (HNWI) portfolios, with advisers reporting a clear shift in how clients think about cash within their overall finances.
New research from Flagstone and Censuswide shows that 38% of HNWIs say they hold more cash than they did three years ago, with cash accounting for an average of 19% of their total wealth.
A shift in mindset: cash as a destination
Many HNWIs are now actively choosing cash as a destination in its own right. 42% of HNWIs prefer to hold cash while waiting for the right investment opportunities, instead of committing capital to underperforming or unnecessarily risky assets.
Cash commanding more adviser and client attention
As cash balances grow, so too does the focus on ensuring that those balances are working efficiently.
When deciding where to hold cash, 76% of HNWIs say maximising interest rates is their top priority, highlighting the expectation that cash should deliver competitive returns rather than sit idle.
The result is that cash is now commanding a greater share of adviser-client conversations as a deliberate component of wealth planning.
John Martin, Chief Product Officer at Flagstone, comments:
Cash is being used far more deliberately than it was even just a few years ago. It’s no longer seen as a temporary holding while investors wait on the sidelines, and advisers are increasingly turning their attention to dynamic, deliberate and high-performance options for their clients' cash allocations.
What we’re seeing is a clear change in mindset, among both advisers and clients. Cash has been elevated in HNWIs’ eyes as a credible alternative to investing when the risk-reward trade-off elsewhere isn’t compelling. If clients want risk mitigation, capital protection and a guaranteed return, choosing cash is often the most rational decision.
SMEs are also building larger cash buffers
A similar shift is underway among UK small and mid-sized businesses, with cash playing an increasingly central role in how SMEs manage risk, resilience and future growth.
41% of SMEs say their cash reserves have increased over the past three years, with businesses now holding an average of nine months’ working capital in cash.
Looking ahead, this approach shows little sign of reversing, with 34% of SMEs expecting to increase their cash reserves further in 2026.
John Martin continues:
What’s notable is that higher cash balances aren’t simply a defensive reaction. SMEs are holding cash to preserve flexibility, so they can manage costs, withstand disruption and still act decisively when opportunities emerge.
