CMC Markets (LSE): CMX) has launched a Junior Cash Individual Savings Account through its CMC Invest platform, expanding the FTSE 250 broker’s reach beyond its core CFD business and into long-term family savings. The account pays variable interest of 3.56% AER, accepts deposits from £1, and is opened and managed entirely online, the company said.

Interest is paid monthly, and existing JISAs held with other providers can be transferred, according to the company. CMC described the launch as part of its strategy to bring trading and investing to a more unified offering, based on…

The rate beats the major banks but falls below the best building societies
A rate of 3.56% puts CMC’s Junior Cash ISA above several major offerings, including Halifax’s Junior Cash ISA at 2.35% AER and NS&I’s at 3.55%, although it lags behind some specialist building society products such as Leek Building Society’s 3.85%. CMC has not disclosed how long the introductory rate will last, and the variable structure means it could move with broader interest rate conditions.
JISA gives families “a simple, safe and tax-efficient way to start building wealth for their children” and “expands our offering to the next generation of investors,” said John Bendall, chief operating officer at CMC. The account was designed to be “easy to open and easy to manage,” said Lachlan Rourke-Davies, the product manager who led the build.
The Junior ISA market itself remains tightly defined by HM Revenue and Customs rules. Parents and guardians can pay up to £9,000 per child each tax year into a combination of cash, stocks and shares, with the funds locked in until the child turns 18. The size of the account makes it a niche product compared to adult investment accounts, but providers see it as a long-term relationship that can be converted into a full investment account after a decade or more.
CMC Invest adds another layer to wealth building
The Junior Cash ISA is the latest piece in the ongoing expansion of CMC Investwhich CMC originally launched in the UK in October 2022 as a commission-free stock trading platform.
The unit has since been added Flexible stocks and shares ISAsA USD portfolio, and access to over 12,000 global stocks and ETFs. In late 2025, CMC rolled out a single multi-asset platform that allows clients to hold stocks and trade derivatives within a single account, along with a three-phase plan to evolve into what the company describes as a financial “super app” that combines TradFi, DeFi, and eventually banking products.
CMC has not disclosed the pricing assumptions behind the 3.56% rate, the spread it expects to earn on cash balances, or whether it intends to add a stocks and small shares ISA.
Leveraged brokers are racing to secure long-term clients
This launch opens a broader pattern across the CFD industry, where companies that built their businesses on leveraged retail trading have spent the last several years diversifying into wealth management, passive investing, and now products aimed squarely at long-term family savers.
Trading 212which was one of the first to disrupt commission-free share trading, received FCA authorization for self-invested personal pensions in February 2026 after a five-year wait, and is now positioning exchange-traded cash savings and tax-efficient cash savings as its primary growth lines rather than CFDs.

From leveraged trading to family finance
CMC Multi-asset payment It was clear in the mediator’s results. Trading revenues rose 50% in the first half of fiscal 2025 To 131.3 million pounds sterlingThe group has guided towards 45% revenue growth on the back of cost cuts and new product launches, including its partnership with Revolut which distributes access to CFDs through the new bank app. The investment arm has been a smaller revenue contributor than CFDs, but management has pointed to it as a strategic growth lever.
Whether JISA itself is moving the needle on group revenues is a different question. Starter ISA balances are capped, locked in for years, and pay interest which the provider funds from the cash spread on the client’s money.
The strategic value is family. A family opening a Junior Cash ISA for a five-year-old is a candidate, in CMC’s bet, for having an Adult ISA, a SIPP and eventually an investment or trading account on the same platform.
This in turn is the longer game now being played across the CFD industry: as the addressable pool of new leveraged retail traders shrinks, brokers reach the next generation before another platform gets there first.
