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.

Naweed Mahmood ·

CMC Markets does a number of things exceptionally well. The app is consistently reliable and always available when you need it, which is crucial in fast-moving markets.

One standout feature is how quickly prices become available. For example, when Sunday trading opens, CMC Markets provides pricing almost immediately, whereas other platforms can take several minutes before showing any market activity. That early access can make a real difference.

Another major advantage is the flexibility in position sizing. CMC allows you to take very small positions, unlike some providers that enforce larger minimum contract sizes. This gives you much better control over your risk, which is especially important when trading CFDs and other leveraged products. It makes the platform more accessible and, in my view, safer for managing exposure.

Overall, the combination of reliability, speed, and flexibility makes CMC Markets stand out from many other providers.
