If you have some spare cash lying around, the lesson of old would be to put it away in some form of savings account, but rampant inflation is undermining the real returns cash ISA customers can achieve. So, are cash ISAs worth it?
While this still represents a significant loss, the picture has improved from the end of last year when savers were suffering near double-digit losses.

Are cash ISAs worth it?
When CPI inflation hit 11.1% in the 12 months to October 2022, the monthly interest rates available on cash ISA deposits, including unconditional bonuses, stood at just 1.69%, meaning cash ISA savers suffered a real terms loss of 9.41%.
Even in March 2023, savers bore an 8.15% real terms loss.
July 2022 marked the highest loss in over a decade when savers faced a decline of 9.42%.
This was the highest real terms loss on cash ISA savings in over a decade, coming in more than triple the previous highest loss of -2.81% in November 2017.
“Although the picture has improved in certain corners of the market even savers on the very best rates will be realising a real term 3% loss,” says Rachael Griffin, tax and financial planning expert at Quilter.
Cash ISAs have long been an “easy way to save money with comparatively little risk,” she adds, but they still get “ravaged by the impact of inflation.”
How can I beat inflation?
According to Quilter’s sums, someone who invested £10,000 in a cash ISA in January 2011 would currently have £11,472.09. Adjusted for inflation, this is just £8,041. In contrast, a £10,000 investment in a stocks and shares ISA, held in the IA Global Equity index over the same period would be worth £26,956 or £18,901 after inflation.
And while these figures do not account for charges that may reduce the final sum, they are indicative of the cash erosion many ISA holders face amid the high-inflationary environment.
According to the latest HMRC data, around 11.8 million Adult ISA accounts were subscribed to in 2021 to 2022 of which 920,000 were cash ISAs.
In recent weeks, savings rates have crept up as competition heats up between banks. While many high street banks had to be spurred by the Financial Conduct Authority to up savings rates, other banks have been offering enticing rates.
Meanwhile, NS&I today upped rates on its fixed-term products - the interest rates paid on NS&I’s fixed-term Guaranteed Growth Bonds and Guaranteed Income Bonds are increasing to 5.00% for new customers, up from the existing 4.00% and 3.90% respectively.
But are these savings methods enough to beat inflation? Quilter’s Griffin says: “If you won’t be needing the money in the next few years, investing could help make your cash work harder, and has a better chance of delivering an above-inflation level of return over the length of the investment although there are still risks associated investing too.”
