Our verdict

CMC Markets has expanded its wealth offering with the launch of a new Junior Cash ISA (JISA), marking a further push beyond trading into long-term savings products for UK families.

The new account, available via CMC Invest, offers a variable interest rate of 3.56% AER, with interest paid monthly. Designed to provide a simple and tax-efficient way to save, the JISA allows parents and guardians to start building a financial nest egg for their children from as little as £1.

Is CMC Invest's Junior Cash ISA Any Good?

While the 3.56% AER rate is competitive, it remains variable, meaning returns could change over time. As with all ISAs, tax treatment depends on individual circumstances and may be subject to future rule changes.

It's also important to note that you can get better returns with a junior stocks and shares ISA (which CMC Invest also offer) as funds are invested in the stock market, as opposed to a savings account.
