Global concerns over increasing government debt and inflation are driving up borrowing costs, with ten-year US Treasury yields reaching an 18-month high and the 30-year yield surpassing 5 percent, a level not seen since 2007. This trend is also evident in Japan, where yields are at three-decade highs.

The United Kingdom faces its own fiscal pressures, including a substantial welfare bill, a large public sector workforce, and unpredictable energy costs. These factors have contributed to the return on the UK's 30-year long-dated bond rising to 5.85 percent. The cost of government borrowing is a significant fiscal item, estimated at £135 billion in last year's budget, exceeding the defense budget and approaching the education budget. While global conditions influence UK rates, mirroring those in the US, domestic budgetary issues also play a role.

Government bond yields have implications beyond public finance. While the Bank of England's key Bank rate is a focal point for consumer and business borrowing, gilt yields are also crucial. Most mortgages are currently fixed for two or five years, with their rates influenced by gilt yields. Similarly, the sovereign guarantee on government borrowing provides a benchmark for commercial lending rates; higher bond rates translate to increased costs for company loans, potentially impacting business investment decisions.

One policy proposal from the Reform party suggests adjusting the inflation linkage for welfare payments. Currently tied to average earnings, a shift to the Consumer Price Index or another measure could potentially save approximately £4.8 billion annually by the early 2030s, offering a permanent reduction in welfare expenditure.

Separately, analysis of public sector pay indicates a potential narrowing of the gap with the private sector. While private sector pay growth fell to 2.8 percent last month amid a weakening labor market, public payroll income increased at more than double that rate. Concurrently, the number of state employees has grown by 50,000 this year, while private sector employment has decreased by 110,000.
