Is cash really 'king'?

You may have read the recent speculation surrounding cash ISA limits, spurred by Rachel Reeves’ recent comment: “At the moment, there is a £20,000 limit on what you can put into either cash or equities, but we want to get that balance right.”

Ignoring the politics, the debate did prompt us to look into relative returns of cash ISAs versus investment ISAs. We went back to when ISAs launched (April 1999) and looked at the average 1-year fix rate available each year. 

 

If you’d put the maximum you could into a cash ISA at the start of every tax year since 1999, you’d have invested £261,520. And if you’d kept rolling up the interest, you’d have turned your original investment into £301,924. That’s £40k of tax free gains! Nice! 

 

But of course, it’s also about what ELSE you could have won… 

 

Let’s take the FTSE All-Share index – not the strongest index over this period but one that everyone knows – and use the same like-for-like tax-year returns. 

 

If you’d put the same £261,520 into a stocks and shares ISA on the first day of the new tax year, and simply held a FTSE All-Share tracker, you’d have an investment worth £491,516 . That’s £229,995 of tax-free gains

Of course, if you’d pushed the boat out, and maximised your Stocks and Shares contributions pre-2013, you’d have put £326,560 in and have £708,837 today. £65k more invested, and £150k more return! 

Cash ISA controversy? No, for many long term investors, there’s a better place to be…
