Rachel Reeves plans £7.5bn tax rise in budget after U-turn on income tax rates

UK Chancellor Rachel Reeves has opted to freeze income tax thresholds for two years, projected to raise £7.5bn, instead of increasing the headline income tax rate, a move influenced by a revised £20bn fiscal gap and political pressures. This decision immediately led to a sell-off in UK government bonds and a depreciation of the pound, as institutional investors expressed skepticism. The market reaction indicates concerns that the combined revenue from the threshold freeze and other proposed smaller tax adjustments will be insufficient to plug the fiscal deficit and establish the desired £15bn buffer, signaling potential challenges for fiscal stability and future borrowing costs.

Analysis

UK Chancellor Rachel Reeves has opted to freeze income tax thresholds for two years, a measure projected to raise £7.5bn, instead of implementing a previously considered increase in the headline income tax rate. This decision, influenced by a revised fiscal deficit estimate of £20bn and political pressures, is complemented by other minor tax adjustments, including ending salary sacrifice pension scheme tax breaks and a new electric vehicle tax, collectively estimated to generate £11.5bn.

The market's immediate reaction was strongly negative, with UK government bonds experiencing their worst day since July 2nd, and the pound depreciating against the dollar. This sell-off reflects significant investor skepticism regarding the sufficiency of these measures to plug the £20bn fiscal hole and achieve the desired £15bn buffer, leading to increased government borrowing costs.

Analysts, such as Kathleen Brooks of XTB, highlight that the bond market is signaling a need for a broader tax base or spending cuts, as current proposals are perceived as inadequate. The perceived U-turn on previous fiscal stances and the "excessive levels of kite flying" around budget details have further fueled market uncertainty and raised concerns about the government's commitment to robust fiscal discipline.

Key Decisions for Investors

• Investors should closely monitor UK government bond yields and the GBP/USD exchange rate for continued volatility, as market skepticism regarding fiscal discipline and the adequacy of proposed revenue measures persists.
• Evaluate current exposure to UK gilts and consider potential hedging strategies given the increased borrowing cost expectations and the possibility of further fiscal uncertainty leading up to the budget.
• Assess the likelihood of more substantial fiscal measures or spending cuts being introduced in the upcoming budget, as the current proposals appear insufficient to meet the market's demand for a robust fiscal strategy.
