Rachel Reeves appears to be running out of ideas, and money. Her latest target is the humble cash ISA, the cornerstone of many savers’ financial security.
Reports suggest the UK Chancellor is considering slashing the annual allowance from £20,000 to £10,000 in a bid to push Britons toward stocks and shares ISAs. The logic, on paper, is that investing boosts returns and helps the economy. In practice, it looks suspiciously like a tax raid dressed up as reform.
Cutting the limit would hit the 14 million people who save exclusively in cash ISAs, many of whom are cautious savers, not investors. Two-thirds of ISA contributions in 2023/24 went into cash, with total holdings now sitting at £360bn. These aren’t City traders sitting on portfolios; they’re people protecting their savings from inflation and poor returns elsewhere.
The Treasury Committee has warned that the move could backfire, hitting mortgage borrowers and driving up costs. Building societies rely on cash ISA inflows to fund lending, so any squeeze on deposits risks pushing up mortgage rates or limiting choice. In other words, the policy could punish both savers and homeowners, two groups Reeves can scarcely afford to alienate.
Committee chair Dame Meg Hillier said it was “not the right time” to make the cut and urged the Treasury to focus on education and confidence rather than coercion. Without that groundwork, she warned, the Chancellor’s attempts to transform Britain’s investment culture will fail.
But Reeves seems intent on fiddling with the wrong levers. Her argument that savers should chase higher returns in the market rings hollow when inflation and taxes are already eroding take-home pay. The idea that people should be nudged into riskier assets by shrinking their tax-free options is a curious form of encouragement.
Critics have branded it what it is: a tax raid in disguise.
With whispers that Reeves may also hike income tax in next month’s Budget, the pattern is clear. She isn’t building an investment culture, she’s building revenue. If this is her idea of fiscal discipline, Britain’s savers have every reason to feel under siege.
