UK considers reforms to direct savings into domestic companies amid cash ISA surge

Britain’s savings landscape is at a crossroads, with a vast amount of capital sitting passively in cash rather than actively fuelling the domestic economy. The UK currently holds nearly a trillion pounds in ISA savings, yet a disproportionately large chunk, around £440 billion, is tied up in cash ISAs, which do little to stimulate growth. This has prompted calls for urgent reforms in the forthcoming Budget to realign savings incentives with economic growth imperatives.

The Individual Savings Account (ISA) was launched in 1999 under Gordon Brown’s chancellorship with the intention of encouraging households to invest their savings in British shares, bonds, and funds. The original vision was to democratise investment, helping channel household savings into ventures that would drive jobs, innovation, and productivity. Back then, the ISA offered savers a £7,000 allowance, which could be allocated fully to stocks and shares, compared to just £3,000 in cash. Fast forward to today, the dynamics have shifted significantly. The cash ISA allowance has ballooned to £20,000, and in the 2023-2024 tax year, £70 billion of ISA subscriptions flowed into cash accounts versus £31 billion into stocks and shares, according to government statistics.

This preference for cash is backed by rising interest rates making cash ISAs more attractive. Reports reveal that over two million individuals opened cash ISAs in that period, nearly ten times more than those choosing stocks and shares ISAs. The surge in cash ISAs was driven in part by the Bank of England’s interest rate hikes, which reached 5.25%, enhancing the appeal of cash savings.

Yet this prevailing trend raises concerns about the underutilisation of household savings as a force for economic growth. Steven Fine, CEO of investment bank Peel Hunt, argues that the current ISA structure strays far from its founding purpose. He advocates cutting the cash ISA limit to £10,000, a figure supported by data showing that two-thirds of savers never hit the current £20,000 cap. The money saved inward should be encouraged to flow more robustly into UK-listed companies, aiming for at least half of the stocks and shares ISA contributions to be directed domestically.

This proposal echoes an earlier model from the 1980s under the Personal Equity Plans (PEPs), which required three-quarters of investments to be in British companies. The rationale is to reverse the trend where UK pension funds and savings disproportionately support overseas companies, examples include UK workers’ pension money buying shares in US giants like Walmart or Pfizer, rather than domestic businesses. Such outflows increase the cost of capital for UK companies and contribute to a gradual exodus of listed companies seeking more favourable markets abroad.

Critics sometimes argue that reducing cash ISA limits could negatively impact mortgage lending, but evidence suggests otherwise. Historical data from 2017-18, when the cash ISA limit increased, shows mortgage lending was flat, indicating that demand for mortgages is influenced more by interest rates, affordability, and buyer confidence than ISA caps. Any reduced savings in cash ISAs could be redirected into other savings vehicles without harming the mortgage market significantly.

The government’s anticipated move to halve the tax-free cash savings allowance in the upcoming November Budget aligns with these concerns. This policy shift aims to promote investment in shares and support the rebalancing of domestic investment. It’s a move away from supporting “lazy money” parked in low-return, low-growth cash accounts toward fostering a more dynamic, investment-rich economy.

While the ISA reforms are not about nostalgic protectionism, they stand as a pragmatic response to a changing economic environment where British companies employ millions, pay substantial taxes, and underpin regional prosperity. Directing individual savings toward these companies through tax incentives could bolster innovation, productivity, and long-term growth, helping to restore confidence in British public markets.

The debate underscores a broader economic challenge: how to ensure that the country’s substantial savings pot is mobilised effectively to support its own economic ambitions, rather than subsidising growth and dividends in other nations. As the Budget approaches, the call is clear, Britain’s savings cannot afford to stay idle if the UK economy is to flourish in an increasingly competitive global landscape.
