Stocks & Shares versus Cash ISAs

Stocks & Shares versus Cash ISAs

Published: 15 Jun 2018 Updated: 13 Jun 2022

After a relatively calm 2017, stock markets have definitely been more volatile since the beginning of this year. However, with high inflation and low interest rates, we still think Stocks & Shares ISAs may offer good opportunities for investors who are able to tolerate the ups and downs.


Inflation is the rate at which prices for goods and services rise and, as a result, buying power falls. Right now cash ISA interest rates are below inflation, with Consumer Prices Index (CPI) inflation at 2.4%* and the highest yielding cash ISA paying just 1.69%**. This means that your cash savings are likely to be growing less quickly than prices are rising – so even if your savings account balance isn’t decreasing, you’re actually losing money in real terms.

Cash ISA interest rates are below inflation.

Risks and returns

If you are concerned about inflation and can tolerate a higher degree of investment risk, you could consider moving some of your cash savings into a Stocks & Shares ISA. Investments have the potential to give you higher returns than Cash ISAs, in excess of inflation. Of course, investing comes with risks. Stock markets can fall and you could end up with less money than you started with.
