UK's Rising Borrowing Costs: A Challenge for Chancellor Rachel Reeves

Economists are expressing concerns regarding the UK’s fiscal outlook as borrowing costs soar to the highest levels this century. The Office for Budget Responsibility (OBR) is expected to revise its forecasts next month, indicating a potential failure for Chancellor Rachel Reeves to meet her fiscal rule targets. Recently, the yield on 30-year government bonds, known as gilts, reached 5.35%—the highest since 1998—while 10-year bonds hit 4.784%, marking the peak since 2008.

The UK government, which typically spends more than it collects in taxes, relies on borrowing to bridge this gap, primarily through bonds. These gilts, traditionally seen as safe investments, are primarily purchased by financial institutions like pension and investment funds. Currently, servicing the national debt is projected to consume 7% of public expenditure, a figure based on lower borrowing rates that may need adjustment given the current climate.

The government reaffirmed its commitment to economic stability and emphasized the importance of adhering to fiscal rules, hinting that future changes may involve spending cuts. A £2bn auction of long-term government debt recently revealed the highest interest rates for such loans since 1998, with a noted increase in market scrutiny over bond issuances from both the UK and US, alongside worries about persistent inflation.

While the immediate impact of these high borrowing costs has mostly skirted household fixed mortgage rates, ongoing increases could affect the OBR’s forthcoming forecasts. The overall economic context includes risks of stagnation and inflation, leading to concerns about ‘stagflation’, especially in light of potential shifts in global policies under incoming US President Donald Trump. The situation signifies a troubling yet important adjustment period for the UK economy as it navigates rising borrowing costs and their implications.
