If a stock market crash is a head-on collision, then inflation is a slow puncture. Yet both can cause things to break down and can be just as damaging to your money.<\/p>\n
Last year alone, UK savers saw around \u00a317.6 billion wiped off the real value of their cash savings once inflation was accounted for, according to Fidelity analysis.<\/p>\n
The loss wouldn\u2019t have been immediately noticeable on bank statements. It happened gradually, as prices rose faster than the interest most people were earning on their savings.<\/p>\n
Why cash lost value in 2025<\/p>\n
At the end of last year, UK inflation stood at 3.4%, well above the Bank of England\u2019s 2% target.1\u00a0Over the same period, the average interest rate paid on easy\u2011access savings accounts was just under 2%, according to Bank of England data.2\u00a0This means many savers were effectively going backwards in real terms.<\/p>\n
Even though fixed\u2011rate savings paid more on average (3.56%), easy\u2011access accounts remain the most popular home for cash.3<\/p>\n
With UK households holding roughly \u00a31.88 trillion in cash deposits,4\u00a0the gap between inflation and savings rates added up to a substantial collective loss over the year.<\/p>\n
Assuming 70% of household savings were held in easy-access accounts and 30% in fixed-rate products, our analysis shows the real value of cash savings fell by around \u00a317.6bn over 2025.<\/p>\n
Put simply: if the interest on your savings doesn\u2019t keep pace with rising prices, your money buys less over time \u2013 even if the balance on your account looks higher.<\/p>\n
How investments performed in 2025<\/p>\n
By contrast, stock markets delivered a strong reminder of why many people choose to invest for the long term. In 2025, global equity markets performed well, with the MSCI World Index<\/a> delivering a total return of around 13% in sterling terms.5<\/p>\n Fidelity estimates that if just a quarter of UK household cash savings had been invested instead of left in cash, the real value of that money could have increased by around \u00a344 billion, even after accounting for inflation.<\/p>\n While this kind of return won\u2019t happen every year, it highlights the opportunity cost of holding large amounts of cash when inflation is high. Over time, investing gives money the potential to grow faster than prices rise, rather than gradually losing purchasing power.<\/p>\n The hidden risk of holding too much cash<\/p>\n Cash plays an important role in most financial plans. It provides security, flexibility and peace of mind. Many people sensibly keep three to six months\u2019 worth of essential spending in cash as an emergency buffer, and retirees often hold more to cover short\u2011term needs.<\/p>\n The problem arises when large sums sit in cash for long periods with no plan.<\/p>\n Fidelity research shows that, historically, cash has struggled to protect against inflation over the long term.<\/p>\n Looking at every rolling 10\u2011year period since the late 1980s, UK equities beat inflation around 95% of the time, compared with just over half of the time for cash.6\u00a0While markets can be volatile in the short term, this highlights the long\u2011term risk of relying on cash alone.<\/p>\n What could savers do differently?<\/p>\n There\u2019s no single answer that suits everyone, but there are practical steps savers can consider to reduce the risk of inflation quietly eating away at their money:<\/p>\n 1. Make sure your cash is working hard 2. Be clear what each pot of money is for 3. Consider investing for the long term 4. Spread your risk 5. Review your plan as life changes Got a burning question you want to ask? Why not drop us a line.<\/p>\n
Check the interest rates on your savings regularly. Many easy\u2011access accounts pay far less than the best rates available, and switching can make a meaningful difference over time.<\/p>\n
Short\u2011term needs and emergency funds belong in cash. However, you may be able to take more risk with money you don\u2019t expect to need for five years or more. This comes with the potential for higher returns that can help to offset inflation.<\/p>\n
Investments can go down as well as up, but over longer periods they have historically offered a better chance of beating inflation than cash. Even modest amounts invested regularly can make a difference.<\/p>\n
You don\u2019t need to choose between \u2018all cash\u2019 or \u2018all invested\u2019. A mix of cash, bonds<\/a> and equities can help balance stability and growth, depending on your goals and time horizon.<\/p>\n
Inflation, interest rates and personal circumstances all change. Revisiting your savings and investments from time to time helps to ensure your money is still aligned with your needs.<\/p>\n
