Yesterday’s (26 November) Autumn Budget delivered by Chancellor Rachel Reeves contains several important changes affecting Stocks and Shares ISA investors.

While the headlines focused on Cash ISA restrictions, the Budget also included measures that make tax-efficient investing through stocks increasingly attractive.

Notably, from April 2027, the annual Cash ISA allowance for those under 65 will be cut from £20,000 to £12,000. This hopefully encourages savers to allocate more of their ISA allowance into shares. The shift aims to promote increased investment in the UK stock market to help boost the economy.

It’s a smart move in my opinion, since stocks historically offer superior long-term growth compared to cash holdings — especially in an inflationary environment. Additional Budget measures included a 2% rise in income tax on savings outside ISAs and pensions. This includes dividend income, which provides further incentives for investors to shelter funds within ISAs.

How this affects UK investors

The market reacted relatively well on Wednesday, considering, with the FTSE 100 and FTSE 250 seeing mild gains. The news appeared to ease some borrowing concerns, although initial reactions to the UK housebuilder sector were mixed due to unchanged housing policies.

The ISA change means investors could benefit from shifting funds from a Cash ISA into stocks. Naturally, this comes with added risk so it’s important to pick stocks carefully.

Two sectors that are already showing promise post-Budget are finance and mining. Lloyds saw notable gains after the announcement, as the Chancellor chose not to impose windfall taxes on bank profits. Meanwhile, wealth manager St James’s Place gained 5% on the day, benefitting from its position in providing investment guidance to clients.

A compelling option?

Aside from financials, one stock I think could benefit from the economic uncertainty is the globally-diversified mining group Anglo-American (LSE: AAL). Its exposure to precious metals and other key commodities make its a top choice among investors looking for a hedge against stubborn inflation.

It has appeal as a dividend-paying stock with growth prospects rooted in global demand for metals. Moreover, its solid balance sheet and focus on sustainable mining practices strengthen its long-term investment case. As such, it’s worthy of consideration by ISA investors seeking stable dividend income and capital appreciation amid today’s uncertain UK economic landscape.

The group is currently involved in a major merger plan with Canada’s Teck Resources, valued at over $60bn. It’s a complex deal with incredible potential but it comes with significant challenges, including regulatory approvals and integration risk.

But overall, I believe the stock’s inflation hedge properties, reliable dividend policy and international diversification make it worth further research in a post-Budget environment.

Taking a cautious view

For ISA investors, focusing on dividend-paying stocks with strong fundamentals and tax-efficient positioning post-Budget is key. Bank stocks, insurers and wealth managers could all benefit from favourable taxes. Meanwhile commodity stocks may be beneficial as a hedge against inflation.

In the current investment landscape shaped by fiscal tightening and market volatility, a cautious approach using well-balanced diversification is key to risk reduction.The US is facing its own struggles. So British investors may find comfort in the FTSE 100’s broad selection of defensive shares.
