Will Reeves Slash Cash ISAs?

Hopefully you will know that I am a fan of having cash, we all need it for ‘liquidity’. In plain English – that means having money easily available without needing to sell anything. This is usually best for your emergency fund. This is a number (sum) that helps you to sleep well at night and quite frankly depends on your life stage. A measure of 3, 6 or 12 months of normal spending is helpful plus planned spending projects (not normal spending) over the next three years.

Keeping more than this in cash will likely erode the value of your spending power. You are likely to be going backwards. You might say “backwards, but at least with certainty – compared to investments” well, that is true in the short term but in the long term, whilst nothing is certain, we have yet to see a period when cash beats shares over 10 years or longer.

So, the news that the Chancellor (Rachel Reeves) is contemplating either scrapping or reducing the Cash ISA allowance from £20,000 to £4,000 may be a surprise for some of you. It’s because in theory holding cash doesn’t really serve anyone very well, least of all the economy, but investing in businesses … well that helps create wealth. That’s why she is considering it.

It would seem that this will only start from the new tax year (if at all) and nobody is expecting her to tell us that you can only hold £4,000 in total in Cash ISAs – which would be highly unlikely. Whilst you may find this an unwelcome change, it’s worth remembering that Cash ISAs always had a lower allowance until the 2015/16 tax year when the allowance became £15,240.

As we are still in the 2024/25 tax year data isn’t up to date, honestly in this digital age, I don’t understand why HMRC are so behind. Anyway, interest rates obviously improved over the last couple of years and more people used Cash ISAs, 63% of contributions to ISAs in 2021/22 were into Cash ISAs. People forget the impact of inflation which is still not within range, and Cash ISAs continue to provide a negative return. Quilter did some research and found that £10,000 into a Cash ISA in December 2012 would now be worth £11,955 but when adjusted for inflation that’s really £7,918. In contrast, the same amount invested into a global shares index fund would be worth £33,526 (£22,221 after inflation).

You may have seen my inflation diagram about a first-class stamp, something we can all relate to and perhaps why there are fewer Christmas and Birthday cards being sent.

• 1985: 17p
• 1995: 25p
• 2005: 30p
• 2015: 63p
• 2025: £1.65

Your money has to keep pace with inflation.  10 years races by, but holding your hard-earned money in cash that provides a negative return is only good for short-term projects and emergency funds.

The current ISA allowance for 2024/25 is £20,000.  The Junior ISA allowance (for those under 18) is £9,000.
