The investment platform IG is advocating for a major overhaul of UK savings, suggesting that Cash ISAs be replaced by a £1,000 investment boost for every UK-born child. This plan aims to encourage early-life investing via junior stocks and shares accounts rather than traditional cash savings.

A £1,000 injection for every UK-born child

The investment platform IG is calling for a fundamental shift in how the UK manages household wealth. Instead of maintaining the current tax-free status of Cash ISAs, IG suggests the government provide a £1,000 grant to every UK-born child to be invested in a junior stocks and shares ISA. This proposal aims to foster a culture of long-term investing from an early age.

Michael Healy, the chief executive of IG Consumer, argues that this move is essential for building financial resilience. According to the report, Healy believes that making investing a "normal part of life" is key to heling households prepare for the future. By redirecting tax breaks from savers to young investors, the platform suggests the government can better encourage productive economic growth.

The £610 million revenue vs £700 million cost equation

The economic logic behind the proposal relies on a delicate balance of tax receipts and new spending. IG's modelling suggests that abolishing Cash ISAs could generate up to £610 million in annual tax revenue by the 2032-33 fiscal year. This revenue would go toward funding the estimated £700 million annual cost of the proposed child investment grant.

The scale of the existing market is significant.. Bank of England data indicates that households contributed roughly £48 billion to Cash ISAs during the 2024-25 period. IG estimates that if these accounts were scrapped, approximately 51 per cent of those funds would transition to taxable savings accounts, where savers would face an effective tax rate of 17 per cent. The platform notes that current Cash ISA subscriptions, which rose by £26.1 billion last year, significantly outpace the growth seen in stocks and shares ISAs.

Rachel Reeves' scheduled 2027 limit reduction

This proposal arrives as the UK government is already moving to tighten the rules around tax-free savings. As reported by the source, Chancellor Rachel Reeves previously announced in the 2025 Budget that the annual Cash ISA limit for individuals under the age of 65 will be slashed from £20,000 to £12,000 starting in April 2027. This poliicy change is intended to incentivize citizens to move their money into the stock market.

While the government aims to boost the economy by encouraging investment in British firms, the current approach focuses on restriction rather than direct incentive. IG’s proposal offers an alternative: rather than simply lowering the ceiling on what people can save in cash, the government could actively seed the next generation's investment portfolios.

Why 64% of ISA subscribers still choose cash over stocks

Despite government efforts to promote equity investment, a massive portion of the population remains cautious. Data shows that cash accounts accounted for 64 per cent of all adult ISA subscriptions in the 2024-25 financial year. This preference highlights a significant gap between policy goals and consumer behavior.

There are several unanswered questions regarding the feasibility of IG's plan:

  • How would the government manage the political backlash from millions of savers who rely on Cash ISAs for "rainy day" funds?
  • Would the £1,000 grant be enough to overcome the inherent risks of the stock market for new investors?
  • How would the transition of new contributions into taxable accounts affect household stability?

    • Harriet Guevara, the chief savings officer at Nottingham Building Society, has already voiced concerns about the importance of these tools . She noted that Cash ISAs are vital for families who prioritize security, with many customers using their full £20,000 allowance to meet specific financial goals. This suggests that simply incentivizing stocks may not be enough to change the fundamental risk appetite of the British public.
