Rachel Reeves is preparing to launch a review of the Isa market within weeks in a push to encourage savers to channel more money from tax-free cash into British stocks, according to people familiar with the plans.
The Treasury will begin a consultation to gain views across the City of London on how to reform the UKโs Isa regime, industry figures said, as the chancellor seeks to bolster what she calls โa culture in the UK of retail investingโ.
The move could pave the way for one of the biggest shake-ups of the Isa market since its creation in 1999, following calls from some large City firms to cap the amount that can be held tax-free in cash.
The UK has four main Isa products, including the cash Isa, which is by far the most popular product, housing ยฃ300bn of savings at present. Isas allow individuals to save and invest up to ยฃ20,000 a year free of income and capital gains tax.
The Treasury paper is expected to be launched within weeks and potentially at Reevesโ Mansion House speech to City executives in July, when the government is aiming to publish its Financial Services Growth and Competitiveness Strategy.
โMansion House is all about getting more money into the UK,โ one of the people familiar with the plans said, adding that any reforms flowing from the consultation could feature in Reevesโ Autumn Budget.
The Treasury said โno decisions have been takenโ but that the government was โlooking at options for reforms to Isas that get the balance right between cash and equitiesโ.
Reeves said this month that she wanted โto create more of a culture in the UK of retail investing, like what you see in the United Statesโ, in order to help savers achieve better returns and โsupport the ambition to grow the economyโ.
The Financial Times reported in January that City firms were urging Reeves to scale back tax breaks for cash Isas. Savers poured ยฃ4.2bn into cash Isas in March, up by almost one-third compared with the previous year, according to investment site Hargreaves Lansdown.
Companies including insurance group Phoenix and the London Stock Exchange Group told the chancellor in January that money in cash Isas could generate better returns for savers if it was invested in stocks and shares, while supporting Londonโs shrinking equities market.
Fidelity International is among the firms to have called for a single Isa product, within which individuals could move between cash and stocks and shares, and suggested limiting the cash portion to ยฃ4,000.
Despite speculation, Reeves did not set out changes in the Spring Statement in March, although the government at the time said it was โlooking at options for reformsโ to โget the balance right between cash and equities to earn better returns for savers, boost the culture of retail investment, and support the growth missionโ.
One industry figure said a consultation should lead to โsomething more concrete in the Budgetโ in the Autumn. โWe do know the Treasury is keen to listen, so they might find a paper helps to formalise those conversations and lighten the load of meetings theyโve been asked to,โ they added.
Tomย Selby, director of public policy at investment site AJ Bell, said the government was โabsolutely right to be looking at whether the current Isa system does enough to foster a healthy investing culture in the UKโ.
But Carol Knight, chief executive of The Investing and Saving Alliance, a not-for-profit organisation, said โcutting the tax benefits of [the] cash Isa will not encourage people to invest moreโ, and urged ministers to offer better support to Britons on how best to make use of their savings.
