Why Playing It Safe with Cash Could Be Your Riskiest Move Yet

They say ‘time is money’, and nowhere is that clearer than when it comes to investing. Yet millions of people still leave large sums of cash sitting in bank accounts. It feels safe, but “safe” can come at a hidden price: lost growth. Every year you wait, inflation eats away at your money’s real value and you miss out on the opportunity to grow your wealth through the compounding of returns.

Why Cash Isn’t Safe Anymore

Whilst it’s no longer front page news,  interest rates have fallen back, and inflation is steadily chipping away at what your money can buy. Keeping your money in the bank might feel secure, but over the long term it risks shrinking in real terms. That old advice of “leave it in the bank, it’s safe there” no longer holds true. Safety now comes with a different cost, the opportunity you’re giving up by not investing.

This isn’t about avoiding cash altogether. Everyone needs a buffer for emergencies and short-term spending. The key is not leaving too much sitting idle, just as you wouldn’t put everything into the stock market or a single high-risk investment. Balance is what matters.

The £100,000 Example

Imagine two people each starting with £100,000.

• One leaves it in a bank account.
  
• The other spreads it across a stocks and shares ISA, a mix of bonds, and pension contributions.
  

After 20 years, the cash saver may only see a modest increase once inflation is factored in. The investor has the potential for higher growth, though returns are not guaranteed and the value of investments can go down as well as up.

The example illustrates possible outcomes, but actual results will depend on market performance and individual choices.

Why People Leave Money Sitting Still

So why do so many people keep their money parked in cash when the evidence shows it loses value over time? For most, it isn’t about logic, it’s about behaviour. We tell ourselves we’ll invest “when the time is right,” or we convince ourselves the risks outweigh the rewards. In reality, the hesitation usually comes down to three things:

• Fear of risk - the idea that the stock market is dangerous.
  
• Procrastination - putting it off until “next year.”
  
• Habit - a belief that banks are the safest place for savings.
  

The reality is that doing nothing is often the riskiest choice. By standing still, your money loses the chance to grow.

Bringing It Together

Many people have money scattered across old ISAs, forgotten savings accounts, and pensions they haven’t looked at in years. Left on autopilot, these funds often sit in cautious, low-return investments. Bringing them together into a clear, modern structure, whether through ISAs, bonds, or a flexible pension plan, gives you control and clarity and the chance to align everything with your goals.

What You Can Do Instead

The alternative to letting your money sit idle is putting it to work in a way that balances growth and security. That usually means three things:

Make use of tax breaks
Everyone knows about ISAs, but there are countless other allowances and reliefs available. Some will be right for you, others won’t. A financial adviser can help identify which apply to your situation and how to use them to make your money work harder without unnecessary risk.

Build a diversified portfolio
A healthy mix of investments spreads risk and creates resilience. For example, property can provide long-term capital growth and rental income, while fixed income such as bonds can offer stability and predictable returns. Equities, on the other hand, drive growth over time. The right blend depends on your goals and attitude to risk, but a portfolio that combines different assets is usually stronger than one leaning on a single option.

Keep it under review
Markets change, and life moves on, so should your portfolio. Leaving investments on autopilot is little better than leaving cash in the bank. Regular reviews and active management ensure your money continues to work in line with your objectives and your appetite for risk.

Time and Risk Go Hand in Hand

The earlier you start investing, the more choice you have. In your twenties and thirties, you can afford to focus on growth. In your forties and fifties, balance becomes more important. Leave it until your sixties, and options narrow with the focus shifting to capital protection. Waiting limits your choices, while acting earlier opens them up.

Why Acting Now Matters

Across the UK, there’s already a savings gap, with many people underestimating how much they’ll need in retirement. Leaving money in cash or default funds risks falling short of the lifestyle you expect later in life. The sooner you review and act, the stronger your position will be.

An adviser can help you decide how much to keep in cash as a buffer, where to invest for growth, and how to bring scattered pots together so they work harder. The best time to take control was yesterday. The next best time is today.
