UK government bonds are currently under pressure as Prime Minister Andy Burnham outlines an economic agenda that is testing market confidence in fiscal discipline. Investors are particularly focused on his stated intention to utilize flexibility within existing fiscal rules. This concern, combined with already elevated borrowing costs due to higher energy prices and inflation risks, is contributing to the pressure on gilts.
On Burnham's first day in office, ten-year UK gilt yields rose 0.08 percentage points to 5.04%, underperforming French and Italian equivalents which saw increases of only 0.02 percentage points. This indicates investor apprehension regarding possible higher government spending under his administration. While Burnham has committed to existing fiscal rules, his plans for a cost-of-living package and a potential increase in the personal allowance are raising worries about fiscal loosening without clear funding strategies.
Market reactions highlight the UK's challenging fiscal environment. The Resolution Foundation calculated that unfreezing the personal allowance next year alone would cost £3.7 billion by 2029-30, emphasizing the need for any such move to be fully funded. The UK already faces the highest borrowing costs in the G7, exceeding 5.2% in May, and spends over £100 billion annually on debt interest. Rising oil prices due to the Iran war further exacerbated these pressures, pushing UK borrowing costs to their highest since 2008.
Financial analysts express concerns, with Stephen Jones of Aegon Asset Management noting that markets have only seen hints of increased spending and limited reform. John Stopford of Ninety One stressed the narrow margin for error, urging Burnham to build fiscal credibility. James Carter of W1M emphasized that maintaining market confidence through disciplined policy and communication is crucial for preserving fiscal room for maneuver. Business groups are also advocating for a predictable tax environment to support sustainable growth.
Despite these concerns, some analysts suggest Burnham might have a modest amount of fiscal headroom. ING noted that he could leverage approximately £16 billion in additional borrowing room this autumn, stemming from planned changes to the fiscal framework. This could help offset negative impacts from higher borrowing costs and revised migration assumptions in Office for Budget Responsibility forecasts. However, significant fiscal loosening, especially measures like unfreezing the income tax-free allowance, which could cost £11 billion per year, would likely be viewed negatively by markets, as the allowance freeze is a key component of current deficit reduction efforts.
