A Labour victory: what could it mean for UK stocks?

​​​​UK elections: barring a major upheaval, little effect on UK stock market expected ​

​The 2024 UK Labour party manifesto put forth an array of policy proposals that could have significant implications across the British economy should Labour take power in the next general election.

From tax changes to increased worker rights, Labour aims to enact reforms that they argue would create a fairer society. However, some of these policies have sparked concerns over potential fallout for UK businesses and equity markets.

​While Labour has pledged not to raise income taxes, national insurance contributions, or VAT rates, the party has indicated openness to hiking other levies like capital gains taxes (CGT). Labour also intends to remove value-added tax and business rate exemptions currently benefiting private schools. These schools may opt to increase fees by up to 20% to compensate, reducing disposable incomes.

Additionally, Labour wants to eliminate the non-dom tax status, which allows some foreigners living in the UK to avoid local taxes on overseas income.

​These tax law changes could dampen investor sentiment and appetite for UK equities. Capital gains tax hikes could prompt asset sales before implementation, and reduced disposable incomes could curtail consumer spending - both negatives for UK stocks and economic growth prospects.

​Labour also proposes significant worker right reforms and union power expansion. These include banning zero-hour contracts, stopping "fire and rehire" policies, increasing sick pay and minimum wages, and repealing past union restrictions. While boosting worker financial security and rights, such changes may also lift business costs and curtail flexibility - potentially hampering competitiveness, productivity, and profits.

​Consequently, industries with high labour costs and union representation may face particular challenges adjusting to this new environment. Sectors like transportation, healthcare, education, and construction could experience work stoppages or slowdowns. However, union-dominated industries could also see stock boosts.

Overall though, sweeping pro-union reforms pose risks of business uncertainties and market unease.

​Offsetting concerns over taxes and unions, Labour emphasizes an ambition to spur economic expansion and achieve the G7's highest gross domestic product (GDP) growth rates. The party plans to unlock growth by restoring political stability post-Brexit and implementing a new industrial strategy. Labour claims resulting revenues can finance social spending without tax hikes.

​While supply-side reforms could boost long-term potential, growth also depends on uncontrollable factors like oil prices and external demand. If the economy underperforms, Labour may still pursue tax increases. Nonetheless, any genuine progress in resolving Brexit uncertainties and driving growth could lift business and investor sentiment.

Opportunity for UK shares

​Labour's policy agenda blends risks with opportunities for UK stocks. While higher taxes and empowered unions may hamper some industries and dampen investor appetite, efforts to resolve Brexit issues and unlock economic growth could boost market sentiment.

​With the proposals' impacts unclear, investors may initially respond cautiously to any initial Labour victory but any potential sell-off in the FTSE 100 is likely to be short-lived, especially since most of its constituent companies generate their revenues from outside the UK or are dependent on energy prices, mining costs etc.

Implementation details and evidence of genuine economic progress over time could substantially sway market reactions going forward, though, with foreign investors, who have already entered the UK undervalued stock market earlier this year, adding to their UK share investments.
