Reeves Eyes Spending Cuts If UK Bond Slump Eats Up Headroom

(Bloomberg) -- Chancellor of the Exchequer Rachel Reeves will favor fresh cuts to public spending over tax hikes if soaring UK borrowing costs wipe out her fiscal headroom.

Reeves plans to reaffirm her fiscal rules in a speech in the coming weeks aimed at reassuring investors and businesses about her handling of the economy, according to people familiar with her plans. She will argue that Prime Minister Keir Starmer’s Labour government will prioritize stability and not consider any loosening of budgetary guidelines, said the people, who asked not to be identified discussing unannounced proposals.

Scrutiny on Reeves’ fiscal plans is growing, with the UK among the hardest hit by a rout in global bond markets this week driven by investor concerns over levels of public debt. The sudden rise in gilt yields is threatening to absorb the slim £9.9 billion ($12.2 billion) margin Reeves had left after announcing her first budget as chancellor in October.

If debt costs remain at this level through the next round of Office for Budget Responsibility forecasts due by March 26, she could breach her main fiscal rule against borrowing to fund day-to-day spending. In such a scenario, she would favor departmental cuts rather than coming back for more tax rises like the £40 billion of revenue-raisers in the October plan, one of the people said.

“No one should be under any doubt that meeting the fiscal rules is non-negotiable and the government will have an iron grip on the public finances,” the Treasury said in a statement on Wednesday. “UK debt is the second-lowest in the G-7 and only the OBR’s forecast can accurately predict how much headroom the government has — anything else is pure speculation.”

Labour has prioritized fiscal stability to set itself apart from the former Conservative government, which suffered an ultimately fatal drop in public support after Prime Minister Liz Truss’s uncosted tax and spending plans roiled markets in September 2022. The rout of recent days has brought numerous unfavorable comparisons to the “mini-budget” saga, with rates on inflation-linked 30-year gilts exceeding 2% for the first time since Truss’s tenure. Benchmark 10-year yields jumped as much as 14 basis points to 4.82% on Wednesday, the highest since August 2008.
