Aberdeen Group says rising gilt yields squeeze UK fiscal headroom ahead of Budget

UK gilt yields could fall if the October 28 Budget delivers credible fiscal headroom, avoids unfunded giveaways and maintains predictable financing. The 10-year gilt yield reached around 5.4% at September’s end, roughly half a percentage point above a year earlier. Higher yields have eroded fiscal headroom from £23.6 billion in March to an estimated £8.5 billion—£16 billion. Each quarter-point rise in gilt yields cuts the Chancellor’s headroom by around £2.5 billion—£4 billion. Planned gilt sales total around £246 billion this financial year; a shift toward shorter maturities increases refinancing exposure.
