The Return of Cash: How UK Investors Are Rethinking Liquidity.

For over a decade, cash in portfolios was treated as an afterthought. Long seen as a necessary source of flexibility - but rarely of return - cash is back in focus. In 2025, cash has made a comeback as a strategic asset class.

 

With interest rates still elevated after two years of monetary tightening, UK investors no longer see cash as just a cushion. The question has shifted: how can liquidity work harder in a portfolio?

 

This rethink is reshaping everything from private client mandates to institutional strategies. Cash is no longer a placeholder, it’s an active decision.

 

Yield is back - cash is in demand

 

As of March 2025, the Bank of England base rate stands at 4.5%, after hitting a peak of 5.25% in 2024. Although markets anticipate some easing later this year, cash and short-duration assets continue to offer positive real returns in the meantime.

 

According to Refinitiv Lipper, UK-based money market funds saw net inflows of £11.49 billion in 2024, a strong indicator of renewed investor focus on low-volatility yield. This trend is being reflected across wealth platforms, where allocations to cash and equivalents have become more prominent in diversified strategies.

 

The appeal of short-dated gilts and liquidity funds has also increased for institutional investors and trustees. This is particularly evident for those more focused on capital preservation. In an environment of slowing inflation and modest growth, holding cash is no longer a drag - it's a source of optionality.

 

The strategic role of cash in UK portfolios

 

In SIPPs, ISAs, and bespoke portfolios, cash is being treated with more intentionality. For high-net-worth individuals, this often means:

 

· Retaining a reserve to fund future liabilities or drawdowns

· Parking capital between staggered allocations to alternative investments

· Gaining yield while waiting for better entry points into risk assets

 

Model portfolio providers and asset allocators have responded with higher strategic cash weightings, particularly in balanced or cautious mandates. What was once considered “lazy money” is now a deliberate part of portfolio construction.

 

Meanwhile, investment platforms and custodians are enhancing access to yield-bearing cash instruments. This includes greater use of regulated money market vehicles and shorter-duration bond options that align with liquidity needs.

 

A short-term play or structural shift?

 

The real question is whether this revaluation of cash is a temporary cycle response or a longer-term structural shift in investor behaviour.

 

With inflation gradually tracking back toward the Bank of England’s 2% target, and interest rate cuts widely expected later this year, there’s a risk that investors become overly comfortable in cash. Behavioural finance has shown that reallocation back into equities or credit is often mistimed - especially if liquidity starts to feel “safe.”

 

There are also differences between cash-like instruments. Counterparty risk, duration exposure, and product structure all need to be considered. What looks like simple liquidity can, in the wrong wrapper, become a source of unintended volatility.

 

Treating liquidity like an asset class

 

If the last decade was about the hunt for yield, the next may be about the quality of liquidity. Investors are re-learning how to analyse cash - not just in terms of returns but also of accessibility, flexibility, and its role in overall asset allocation.

 

Cash is no longer just a portfolio filler. It's becoming a legitimate contributor to performance and risk management, particularly during periods of macro uncertainty.

 

Conclusion: Cash has earned a strategic seat, but timing is key

 

The re-emergence of cash as a portfolio component is a rational response to today’s rate environment. However, investors must remain vigilant.

 

Cash plays an important role, but it's not a strategy in itself. Its power lies in what it allows investors to do next: seize opportunities, meet liabilities, and reduce risk. But staying in cash for too long, especially as markets shift again, could mean missing the next wave of returns.

 

In 2025, cash has returned as a strategic asset – and investors are reassessing what that means for the long term.
