Junior ISAs have rightfully become one of the preferred ways for UK parents to build a nest egg for their children’s financial future, but should you be worried about the impact of inflation on the long-term earnings within a JISA?

Because of their tax efficiency, there’s no better way to give your child the best start to their adult life than to begin saving for their future using a Junior ISA.

Junior ISAs are completely tax-free, meaning that if you want to begin investing using a Junior Stocks and Shares ISA, your child will be able to access their accounts once they turn 18 without any percentage of the profits going to the taxman.

When you open a JISA, you’ll be able to deposit up to a £9,000 annual allowance each tax year, meaning that you can save substantial amounts over time, particularly by tapping into the effects of compounding.

Last year’s government commentary on annual savings statistics showed that JISA account holders grew to 1.37 million in the 2023-24 tax year, up from 1.25 million in the year prior.

But as inflation rates throughout the UK begin to adversely affect our spending power, could the long-term benefits of Junior ISAs be impacted? Let’s take a deeper look at the danger posed by inflation and whether it could undermine your child’s JISA investments:

Threat of Inflation

The threat of inflation has been high in recent years, with different causes including post-pandemic supply chain squeezes and the recent energy shock following the geopolitical conflict in the Middle East.

Inflation reached a 41-year high of 11.1% in October 2022, but generally weighs in far lower each month.

Over the past 10 years, the average UK inflation rate has averaged out at around 3.2%, and this means that your Junior ISA returns should look to be higher than this figure to ensure that your child is consistently growing their spending power in real terms.

Inflation is a threat to Junior ISAs because if the returns are below the rate of inflation, your child will effectively be losing out on their future spending power, despite the numbers in their account increasing over time. This is because inflation measures the rate of devaluation that many currencies experience.

History Favours JISA Growth

Inflation is the primary risk that you need to navigate through as a parent building a Junior ISA for your child. So, how confident can you be that your child’s JISA will continue to grow ahead of inflation rates?

The best way to factor in the dangers of inflation for your child’s JISA is to look at historical trends. According to Moneyfacts data, a typical Stocks and Shares ISA has returned 6.79% on average per year since 2010, while its fixed-rate savings counterpart, the Cash ISA, has mustered 1.79% in comparison over the same period of time.

While Cash ISA averages are lower because interest rates remained historically low for the decade following the 2008 financial crisis, historical trends show that savings-focused JISAs can be more exposed to fluctuations in interest rates, meaning that investing using a Junior Stocks and Shares ISA can be a more effective way to build a nest egg for your child using an individual savings account.

Because Junior ISAs are tax-efficient, they can also empower you to save more effectively over time, making the most of your profits without losing out to taxation as well as inflation.

You also have more control over the investments you hold in a JISA, and this allows you to align your child’s portfolio with the type of financial goals you have for them, either by building a safe and diversified range of stocks and shares or opting for more high-growth speculative equities.

Protecting Against Inflation

Inflation can not only devalue your child’s JISA, but it can also impact the long-term performance of the investments held within your Junior Stocks and Shares ISA portfolio, so it’s important to have a well-rounded range of assets that are more resilient against the risks faced by certain stocks.

The impact of inflation can be uneven throughout the world, and adding more global stocks can be a great way to bypass the impact of inflation in the UK or the United States.

Opting for global equity funds means that your investments can be spread across many different markets throughout the world for balanced access to growth.

By making regular similar value contributions to your child’s JISA, you can also enjoy the benefits of pound-cost averaging, which means you’ll be buying more shares when prices are low and fewer when prices are high.

Making the Most of Your Child’s JISA

Because your child’s Junior ISA can’t be accessed until they turn 18 years old, you can make the most of having a far longer period of time to grow your investments.

This means that while inflation remains a hazard to keep in mind, well-chosen equities can continue to build your portfolio and allow you to use compounding to reinvest your earnings to provide a stronger hedge against devaluation.

Although inflation can certainly impact your child’s JISA, with a Junior Stocks and Shares ISA, the chances of it undermining the value of your loved one’s pot are remote.
