Regarding ISA reform, Reeves examines the minimum UK shareholding

Rachel Reeves, the chancellor, is reportedly thinking of requiring a minimum UK shareholding in the stocks and shares ISA in addition to the rumoured £10k cash ISA cap

It has been reported that Chancellor Rachel Reeves is thinking about requiring a minimum amount of UK shares in stocks and share ISAs.

In an effort to encourage more British citizens to invest in the UK stock market and foster a retail investing culture in the nation, the chancellor is considering changes to the stocks and shares ISA, according to a Financial Times article published on October 17.

It might mean that British citizens are essentially compelled to hold some of their investments in UK-listed stocks, removing the complete geographic flexibility that the current ISA allows for stocks and shares.

Getting British savers to contribute more money to the UK stock market, which has lagged behind the US stock market, is the presumed objective.

Theoretically, a rise in the stock market would accelerate economic growth in the UK.

According to the Financial Times, the chancellor is considering a number of proposals, including removing stamp duty from London-listed stocks held in ISAs and requiring a minimum UK shareholding.

According to reports, Reeves is also considering cutting the cash ISA limit in half, to just 10,000.

The argument for a requirement of UK shareholding.

Theoretically, requiring a minimum UK shareholding under the stocks and shares ISA would encourage savers to purchase UK-based stocks, retaining the financial advantages of ownership in the nation.

Early in 2025, there were rumors that the cash ISA would be cut. Critics said that this would not help the UK's economy because savers would be more inclined to invest in foreign stocks, mostly in the US, which have historically yielded higher returns.

They wouldn't be allowed to do this if it were required that a certain percentage of your stocks and shares ISA be invested in UK shares.

It's still unclear if investors would consciously choose to put their money into stocks that are expected to yield lower returns when they could invest outside of the ISA system, albeit without the tax advantages.

Arguments against the plan.

According to Tom Selby, director of public policy at AJ Bell, the addition of a minimum UK shareholding requirement is reminiscent of the past Conservative government's failed Brit ISA.

The "fundamentally flawed UK ISA proposal" should not be revived, according to Selby, who says the chancellor should not do so.

According to him, any attempt to require UK asset allocations in ISAs would be a fairly blatant political ploy that would greatly complicate the system and offer no clear advantages to investors or the economy.

Since 4050% of ISA assets are already invested in UK-based funds or companies, the government should concentrate its policy interventions on facilitating the shift from short-term cash saving to long-term investing and allowing investors' natural home bias to generate capital gains for UK plc.

Rather, he encouraged Reeves to move forward with eliminating stamp duty on UK shares that are part of the ISA.

Selby went on to say: "At a time when government policy is intended to do just the opposite, stamp duty is a tax that specifically discourages investment in British companies.

Even though the chancellor might wince at the multibillion-pound annual cost of eliminating stamp duty nationwide, a specific carve-out for ISAs to support her retail investing drive could be accomplished for a fraction of this costroughly 120 million pounds, to be exact. That is essentially a rounding error in terms of government spending, and it would eliminate a ridiculous obstacle to ISA investors purchasing stock in UK companies.

Hargreaves Lansdown chief investment strategist Emma Wall expressed support for the proposal to remove stamp duty on UK shares held in ISAs.

"We believe there are better ways to encourage retail investment than a UK mandate," she continued. "However, we find that most of our clients' trades are already into UK shares, and that an unrestricted approach to regional asset allocation yields better client outcomes.

According to AJ Bell, the ISA regime needs to be simplified rather than given additional regulations.

The chancellor should concentrate on streamlining the ISA system as a whole, according to AJ Bell, who claims it is too intricate and may easily perplex customers who choose to switch from cash savings to stock market investing. This misunderstanding, according to the investment platform, is one of the reasons why British people hoard cash.

Using a conservative estimate, research by AJ Bell indicates that there are approximately three million people in the UK who have at least 20,000 invested in cash ISAs and none invested in stocks and shares ISAs.

Just half of that money could be invested, unlocking an additional £30 billion in investment that could boost the UK stock market and yield better long-term returns than keeping the money in cash.

Instead of punishing cash savers, Selby believes the chancellor should encourage them to invest.

By merging cash and stock and share ISAs into a single primary ISA product, he recommended that Reeves "address the negative impact the siloed ISA structure has."

"In addition to streamlining the overall ISA structure, this change would facilitate the shift from cash holdings to long-term investments, bolstering broader initiatives to increase retail investing, enhance financial stability, and stimulate economic expansion," he continued.
