How Inflation and Policy Changes are Reshaping Saving Behaviour in 2026

The United Kingdom has long been a nation of savers, with residents long preferring to avoid risky investments altogether in favour of fixed returns. But 2026 may be the year that we begin to see a fundamental shift in attitudes towards wealth management. 

Using the UK’s differing attitudes to ISA ownership, it’s easy to map out how individuals feel about saving versus investing. 

According to the most recent available figures, which cover the 2023/24 tax year, there were 9.94 million Cash ISA subscriptions domestically, compared to just 4.09 million Stocks and Shares ISA subscriptions. 

The key difference between these two products is that Cash ISAs are generally fixed-rate, savings-focused accounts, while Stocks and Shares ISAs are invested in assets like stocks, funds, ETFs, and bonds. 

Data from a YouGov poll conducted in July 2025 found that just 31% of British adults would be willing to invest in a Stocks and Shares ISA, with 65% of unwilling residents claiming that the approach is ‘too risky.’ 

This is indicative of a more widespread aversion to investing. According to a recent survey, 17% of UK adults claimed to have ‘never heard’ of a Stocks and Shares ISA, while around 22% believe that they don’t know much about investing. 

However, policy changes and shifts in the inflation landscape could reshape saving behaviour in 2026, with more residents eager to adapt their approach to make the most of their returns. 

Inflation Implications

Although many savers who prefer to avoid investing cite risk as a key factor behind their decision, there’s actually an element of risk that can be associated with saving. 

While your money won’t lose value in a savings account, inflation could severely impact your purchasing power. 

The danger is that inflation could outweigh interest rates, leaving you to make a loss in real terms because the value of the pound is devaluing faster than the money that you’re making. 

For instance, if inflation is at 4%, but your account earns 3.6% interest, your money is effectively shrinking in value by 0.4% each year due to prices rising faster than the interest you earn. 

The good news for savers is that inflation rates have entered 2026 lower than interest rates, with UK consumer price inflation rising to 3.4% in December 2025, 0.35% below the 3.75% Bank of England base rate. 

With the top Cash ISA rates in the UK ranging nearer to 4.4%, the prospect of cooler inflation rates could encourage more adults to lean towards saving as a means of growing their wealth in a low-risk way over the year ahead. However, policy shifts could change attitudes in the near future.

Managing Monetary Policy

Although calming inflation is generally a positive factor for savers, expectations are growing for Bank of England interest rate cuts in the months ahead that can once again bring fine margins for profitability for savings accounts like Cash ISAs. 

According to Dani Stoilova, a UK and Europe economist at BNP Paribas Markets 360, a 25 basis point cut to 3.5% could arrive in either March or April in what’s likely to be a standalone lowering of the base rate. 

This would send Cash ISA rates closer to inflation, diminishing the possible returns for investors. 

Another confounding factor for savers is the Cash ISA allowance cut that’s arriving in April 2027. Announced in the recent Autumn Budget, Chancellor Rachel Reeves lowered the tax-free allowance that could be invested in Cash ISAs to £12,000, down from £20,000. 

The move was made with the idea of encouraging more savers to switch towards investing in British stocks and shares as a means of boosting the economy. Crucially, the Stocks and Shares ISA allowance is set to remain at £20,000. 

Whether cutting Cash ISA allowances could prompt more savers to switch up their risk appetite or not, these fundamental rule changes may point towards shifting trends in wealth management. 

Is Investing Too Risky? 

Are UK savers right to be wary of the risk attached to investing? The answer can be pretty nuanced. 

Yes, investing will always be riskier than saving, due to your portfolio being built on stocks and other assets that can theoretically fall to £0 if enough negative events occur. However, taking a more historical look at saving versus investing, it’s clear that there are far greater returns to be made by adopting a higher risk appetite. 

2026 is set to be a transformative year for both saving and investing trends, with further interest rate cuts expected and the prospect of cooling inflation data. 

With Cash ISA allowance cuts expected to prompt more UK savers to consider making their first investments, we may well see the gap between Cash and Stocks and Shares ISA subscriptions closing over the year ahead.
