The run-up to the Budget: Why investors were watching closely
When Chancellor John Healey stood up to deliver his Autumn Budget on 28th October, he faced a difficult balancing act: addressing mounting pressure on the public finances while maintaining confidence in the UK’s economic prospects.
For investors, the stakes extended beyond the possibility of higher taxes. Decisions about government borrowing and public spending can influence interest rates, company profitability and the performance of financial markets.
The challenge facing the Chancellor had become increasingly apparent since March’s Spring Statement. At that point, the Government had an estimated £24bn of room to manoeuvre within its fiscal rules. This financial cushion, known as fiscal headroom, had subsequently come under pressure from higher borrowing costs, inflation and spending commitments.
Although stronger economic growth and productivity had provided some relief, the Government’s commitment not to increase the headline rates of income tax, employee National Insurance or VAT (which account for almost 60% of total tax receipts), restricted its options. Attention therefore turned to more targeted tax measures and where the Chancellor might look to raise additional revenue.
For investors, the central question was whether the Budget could strengthen confidence in the UK economy without placing additional pressure on businesses and financial markets.
The announcements offer some answers, although their longer-term consequences will depend on how the economy and markets respond.
Six key takeaways for investors
1. Fiscal headroom: Why do the Government’s finances matter to investors?
The Government’s ability to manage its borrowing and spending commitments can influence confidence in the UK economy, with potential implications for financial markets and investments.
Having increased to £24bn following tax rises last year, fiscal headroom declined to £15bn amid rising borrowing costs and spending commitments. While the Chancellor introduced a small number of targeted tax-raising measures, he rejected broad-based tax hikes. He defended the reduction in fiscal headroom as an appropriate use of the buffer to absorb some of the impact of the Iran War, while maintaining a focus on fiscal sustainability.
Fiscal headroom is the amount of flexibility the Government has within its own borrowing and spending rules. A stronger fiscal position may help support confidence in government borrowing, potentially benefiting the wider economy and financial markets.
However, limited headroom leaves the Government more exposed to unexpected economic pressures, potentially increasing the likelihood of further tax rises or spending constraints.
For investors, the longer-term implications will depend on whether economic growth and government revenues develop in line with expectations, alongside the response of financial markets to the Government’s fiscal plans.
2. Capital Gains Tax: What could the Budget mean for your investments?
If you hold investments outside tax-efficient accounts, any change to Capital Gains Tax (CGT) could affect how much of any profit you retain when selling them.
Calls for an increase in CGT were rejected by the Chancellor, in favour of a 2% increase in tax on income from property and savings across all tax bands from April 2027.
While tax-efficient arrangements can offer benefits, their relevance will depend on individual circumstances. Tax rules and allowances may also change over time, making it important to consider taxation alongside wider investment objectives rather than in isolation.
3. First-time buyers: Could housing measures support the property market?
Measures designed to help first-time buyers onto the property ladder could influence demand for new homes, with potential implications for housebuilders and related businesses.
The Government confirmed its previously announced equity loan scheme, designed to make new-build homes more affordable and support buyer demand. Eligible buyers will be able to use a government-backed equity loan, including an interest-free period, alongside a minimum deposit of 2.5%.
The scheme could have several implications for the housing market and investors:
-
Supporting buyer demand: Smaller deposits could help some first-time buyers enter the property market sooner, potentially increasing demand for new-build homes.
-
Potential implications for investors: Increased demand may benefit housebuilders and businesses involved in construction and the wider housing supply chain.
-
Risks for homeowners: Smaller deposits provide a limited financial buffer if property prices fall, increasing the risk of negative equity.
-
Wider market challenges: Higher borrowing and construction costs, alongside planning constraints, remain obstacles to the Government’s housing ambitions.
While measures to stimulate demand may benefit parts of the housing sector, the impact on individual businesses and their share prices will depend on wider market conditions and how effectively the scheme is implemented.
4. Bank surcharge: What could it mean for banking shares?
For investors holding UK banking shares, an increase in the tax paid by banks could influence profitability, dividends and the outlook for individual businesses.
The banking sector has delivered strong profits in recent years and was therefore widely viewed as a potential source of additional tax revenue. The surcharge on banking profits was reduced to 3% in 2023, although this coincided with an increase in the main corporation tax rate from 19% to 25%.
The Chancellor’s decision to raise the surcharge to 6% for 15 months from January 2027 to March 2028 is expected to generate £1.5bn in additional revenue over the period.
Higher taxation could place pressure on profits after tax, potentially influencing the earnings available for dividends and other uses of capital. However, the impact is unlikely to be uniform across the sector, with several factors influencing how individual banks may be affected:
-
Business models and profitability: Banks differ in their sources of revenue, operating costs and exposure to UK taxation.
-
Interest rates and lending activity: Wider economic conditions will continue to influence bank earnings, potentially offsetting or compounding the effects of higher taxation.
-
Dividends and shareholder returns: Additional tax liabilities could affect the capital available for distributions, although future dividends will also depend on individual financial performance and management decisions.
The direct effect on overall sector earnings is expected to be limited, although individual businesses may experience a greater impact.
For shareholders, it is important to consider these changes alongside the wider factors influencing banking performance. While some banks may be better positioned to absorb additional taxation than others, future earnings and dividend payments are not guaranteed.
5. Defence spending: Potential opportunities, but uncertainty remains
Increased government spending on defence could support businesses operating in the sector, although the timing and scale of future investment remain important considerations for shareholders.
The Government reaffirmed its commitment to increasing defence spending, reflecting the continuing political and strategic focus on national security. However, it stopped short of committing to spending 3% of GDP on defence by 2030, a target estimated to require an additional £11bn annually.
For investors, greater defence expenditure could provide opportunities for businesses involved in equipment, technology and associated supply chains. Companies securing new government contracts may benefit from increased demand, potentially supporting future revenues.
However, higher government spending does not automatically translate into stronger company profits or investment returns. Procurement decisions, operational costs and the financial performance of individual businesses will all influence how the sector responds.
While the announcement may provide some encouragement for defence-related companies, the absence of a firm timetable limits visibility over the scale and timing of future expenditure.
Share prices can also fall as well as rise, regardless of the outlook for a particular industry, making the financial position and valuation of individual businesses important considerations.
6. Economic outlook: What lies ahead for the UK?
The Government’s forecasts for growth, inflation and borrowing provide important context for investors, helping to shape expectations for businesses, interest rates and financial markets.
Beyond the individual tax and spending measures, the Budget provides an indication of the Government’s expectations for the UK economy.
The Office for Budget Responsibility’s (OBR) latest projections for economic growth, inflation and government borrowing will help shape expectations for the months and years ahead.
Three areas are particularly relevant to investors:
-
Economic growth: The OBR downgraded GDP growth outlook for 2027 to 1.0%, compared to its previous forecast of 1.6%, reflecting the impact of higher energy prices. However, growth is expected to recover to 1.6% in 2028, followed by 1.8% in 2029. Stronger growth may support business profitability, consumer spending and investment activity.
-
Inflation and interest rates: The war in the Middle East has led to a sharp increase in inflation, expected to be 3.1% for 2026 and 3.4% for 2027, before falling back to 2.1%. Persistent inflation and higher borrowing costs could place pressure on businesses and households, influencing financial markets.
-
Government borrowing: The spending commitments outlined in the budget will lead to a fall in fiscal headroom. The outlook for public finances may affect government bond yields and wider confidence in the UK economy.
The Chancellor’s approach to balancing fiscal sustainability with economic growth will therefore be an important consideration when assessing the longer-term implications of the Budget.
However, economic forecasts are inherently uncertain and actual outcomes may differ from expectations. The information and views presented reflect the position at the time of publication and may change as economic conditions develop.
How have financial markets reacted to the Autumn Budget?
The initial reaction of UK shares, government bonds and Sterling can provide an indication of how investors interpreted the Chancellor’s announcements. However, these early movements represent a snapshot of market sentiment rather than a reliable indication of longer-term performance.
In the hour following the Chancellor’s Budget announcement, financial markets provided a muted reaction, suggesting that much of its content was broadly in line with expectations.
During this initial period, government bond yields showed limited movement, while Sterling remained relatively stable against the US Dollar and Euro. UK equity indices were also little changed overall, although performance varied between sectors, with banking shares performing strongly as the announced increase in surcharge was lower than expected.
For investors, these immediate market reactions can provide useful context:
-
Government bonds: Changes in bond yields can influence the market value of existing fixed-income investments, with rising yields generally resulting in falling bond prices.
-
Sterling: Currency movements can affect the Sterling value of overseas investments, either increasing or reducing returns when converted back into Pounds.
-
Equities: Companies and sectors directly affected by Budget announcements may experience greater share price movements than the wider market, including housebuilders, banks, and defence companies.
Importantly, these observations reflect market conditions in the immediate aftermath of the Budget, rather than their position at the time of reading. Financial markets respond to many factors beyond government policy, and the full implications of fiscal announcements can take time to emerge.
While market developments may create opportunities for some investors, they also carry risks. The value of investments and any income arising from them can fall as well as rise, and investors may get back less than the amount originally invested.
What does the Autumn Budget mean for your investments?
The implications of the Autumn Budget will differ depending on the investments you hold, your personal circumstances and your longer-term objectives. While changes to taxation and government spending can influence financial markets, their impact on individual portfolios will vary.
For Redmayne Bentley clients, there are two important perspectives:
If you make your own investment decisions: Understanding how the announcements may affect individual companies, sectors and asset classes can provide useful context when reviewing your existing holdings or considering future investments.
If Redmayne Bentley manages your investments: The Budget forms part of the wider economic and market environment considered by our Investment Managers when making portfolio decisions in line with your agreed investment objectives and circumstances.
The announcements also highlight the importance of understanding how investments are held. Tax-efficient accounts, such as ISAs and pensions, can offer benefits, although their suitability and tax treatment depend on individual circumstances and the rules in place at the time.
While Budget announcements can generate short-term market movements, maintaining a longer-term perspective remains important. Investment decisions should reflect personal objectives, circumstances and attitudes to risk rather than being driven solely by individual political or economic events.
At Redmayne Bentley, we recognise that every investor’s circumstances are different.
