UK Budget faces pressure to balance fiscal discipline with growth amid market volatility

UK Chancellor Rachel Reeves faces significant pressure to deliver a Budget that strikes a delicate balance between cutting spending and raising revenue without stoking inflation, according to prominent fund managers responsible for managing trillions of dollars in investors’ assets. Their insights highlight the complexities and high stakes involved as the UK Government seeks to reassure markets amidst ongoing economic challenges.

The gilt market has experienced considerable volatility this year, with inflation concerns and extensive bond issuance pushing long-term borrowing costs to levels not seen since 1998 during the summer months. Market jitters were amplified by a recent government U-turn on plans to increase income tax, triggering sell-offs and underscoring investor anxieties about fiscal discipline and economic stability.

Leading voices from major investment firms have outlined expectations for the upcoming Budget, underscoring the necessity for a credible fiscal framework. Roger Hallam, global head of rates at Vanguard, emphasised that the government must reaffirm its commitment to its self-imposed fiscal rules, anticipating a combination of tax increases and modest expenditure cuts to restore fiscal headroom by around £15 billion. Hallam suggested that targeted measures to reduce inflation, such as cutting levies on energy bills, could create a virtuous economic cycle, lowering inflation, enabling the Bank of England to reduce interest rates, and ultimately strengthening the UK’s fiscal position through reduced debt servicing costs.

Similarly, Kim Crawford of JPMorgan Asset Management called for discipline in reaffirming fiscal rules and creating a larger buffer against future shocks, provided that such consolidation is funded in ways that avoid stoking inflation. Vincent Mortier, group chief investment officer at Amundi, stressed the importance of credible fiscal planning aligned with realistic productivity growth forecasts, warning that failure to manage expectations could provoke negative market reactions if the Bank of England is unable to resume rate cuts over the next six months.

Andrew Law, CEO of Caxton Associates, highlighted the importance of tax rises that do not harm business or inflation, suggesting options like freezing tax thresholds and adjusting council tax bands as viable measures. He expressed concerns about a potential “doom loop” of stagnant growth and rising taxes but noted that clear government signals on tax policy could break this cycle and foster economic improvement.

Fidelity International’s Mike Riddell observed a fundamental tension, noting that a Budget favourable to gilt markets does not necessarily benefit the broader economy. He argued that while tax increases and spending cuts could dampen growth and inflation, thus enabling Bank of England rate cuts, the government faces the challenge of simultaneously boosting productivity through investment to secure long-term growth.

However, some fund managers voiced reservations about the current fiscal approach. Bill Campbell of DoubleLine expressed disappointment at the recent exclusion of income tax hikes in Budget preparations, fearing that insufficient measures could undermine government credibility and complicate fiscal management in the future. Mark Dowding of RBC BlueBay Asset Management questioned the efficacy of further tax increases given the UK’s already high tax burden, advocating instead for tackling welfare spending and reviewing energy costs, tax revenues from oil and gas, and housing sector barriers, all within the context of the government’s net zero ambitions.

Across the board, the consensus underscores the importance of fiscal credibility. Greg Peters of PGIM highlighted the market’s fragility after recent political U-turns, stressing that credible fiscal tightening must include spending cuts to restore confidence. Andy Chorlton of M&G Investments suggested that fiscal discipline combined with a tight monetary policy could strengthen the UK’s long-term economic outlook, though he warned of subdued growth and declining inflation in the short term.

On the government’s side, recent legislative actions indicate a clear attempt to enshrine fiscal discipline. The Charter for Budget Responsibility has been approved by Parliament, instituting rules to ensure day-to-day government spending is matched by tax revenues, with borrowing limited strictly to investment purposes. This fiscal framework aims to provide economic stability and growth, as highlighted by Chancellor Reeves, who positions these reforms as central to the Plan for Change.

Further reinforcing fiscal rigour is the introduction of the Fiscal Lock Law, which requires that any significant fiscal announcements involving permanent tax or spending changes exceeding 1% of GDP receive an independent assessment from the Office for Budget Responsibility (OBR). This move is intended to prevent avoidance of fiscal scrutiny and to underpin the economy’s foundational stability.

Regarding actual fiscal actions, Chancellor Reeves has committed to boosting public investment by over £100 billion over the next five years, alongside increasing day-to-day spending on key public services like the NHS, education, and criminal justice. The government has also launched an ambitious business deregulation programme aimed at cutting nearly £6 billion in administrative costs for firms, highlighting a pro-growth agenda.

However, despite these plans, uncertainty remains about the fine balance required to reassure markets. The OBR is expected to issue its economic and fiscal forecast in March 2025, which will provide further clarity on the government’s fiscal path and underpin efforts to foster stability and growth.

In summary, the approaching Budget is widely seen as crucial for restoring investor confidence and securing a sustainable economic future for the UK. Market participants are watching closely for disciplined fiscal consolidation measures that manage inflation risk, respect borrowing limits, and simultaneously stimulate long-term growth, a formidable challenge for Chancellor Rachel Reeves in a complex economic environment.
