John Healey will use his first budget on Wednesday to reverse his predecessor Rachel Reeves's decision to slash the annual cash ISA allowance from £20,000 to £12,000. The move signals a philosophical shift: rather than penalising savers to force capital into UK equities, Healey will argue that financial education and incentives are the better route to higher investment returns. The reversal lands well with banks and building societies already bracing for higher taxes in the budget. These institutions depend on cash ISA deposits to fund lending — a £12,000 cap would have crimped their deposit base and, finance bosses warned, risked pushing up mortgage rates. Cash ISAs remain the UK's most popular savings product, exempt from tax on interest, income, and capital gains. Not everyone in the City is pleased. Michael Healy, chief executive of IG Group's consumer division, called it a "squandered golden opportunity." He pointed to a stark imbalance: cash ISA subscriptions surged by £26.1 billion last year, more than four times the increase in stocks and shares ISAs. IG modelling suggests phasing out cash ISAs for new contributions could generate up to £610 million in additional annual tax revenue by 2032-33 without touching existing savings. Quilter's Jo Harris offered a middle path, suggesting the government could introduce an additional investment-only allowance on top of the £20,000 ISA limit, paired with better financial education — a carrot on top of the carrot. The idea acknowledges the core tension: the UK has a savings culture that works for depositors and lenders but starves domestic equity markets of retail capital. The structural question is whether education alone can bridge the gap. The UK's equity investment shortfall is not primarily an information problem — it is a risk-appetite and trust problem, compounded by decades of pension de-risking and a cultural preference for property and cash. Merely telling people stocks are better over the long run has been tried before, with modest results. Healey's choice is politically safe and economically ambiguous. Keeping the allowance intact avoids a fight with millions of savers and the banking lobby simultaneously. But it also means the budget offers no structural mechanism to redirect the £26.1 billion annual cash ISA flow toward productive investment. The carrot exists in principle; it has no calories yet. The real test comes in the detail: whether Wednesday's budget includes any new investment-specific ISA wrapper, tax incentive, or matching scheme — or whether "education" is a placeholder for inaction dressed in good intentions.
