The global bond sell-off deepened today as investors worry the US economy may be running too hot, pushing government bond yields sharply higher across major markets. The sell-off, which began earlier this week, has now spread to UK gilts, with the 10-year yield jumping 1.8% towards its highest level since the 2007 financial crisis.
Why the Global Bond Sell-Off Is Accelerating
Rising bond yields reflect growing concerns that the US economy is overheating, which could force the Federal Reserve to keep interest rates higher for longer. Strong economic data, including robust jobs reports and persistent inflation, have led investors to reassess their expectations for rate cuts. As a result, bond prices have fallen, and yields have surged.
In the UK, the sell-off has been particularly acute. The yield on 10-year gilts has climbed to levels not seen since the financial crisis, driven by similar fears about inflation and government borrowing. This has significant implications for the UK government's fiscal plans.
Impact on UK Fiscal Headroom
Rising gilt yields directly increase the cost of servicing the national debt and issuing new bonds. This eats into the government's fiscal headroom—the buffer that allows it to meet its fiscal rules, which require day-to-day spending to be covered by tax receipts and debt to be falling as a share of the economy.
Rachel Reeves, the Shadow Chancellor, had left a buffer of over £23bn for her successor, John Healey. However, with government spending running above forecast, many City economists predict this headroom has already shrunk. According to the Financial Times, the UK government may now accept a smaller fiscal buffer rather than raise taxes.
Government figures are reportedly preparing to argue that maintaining March's buffer is unnecessary given sharply rising borrowing and energy costs. One source suggested £15bn would be sufficient, while another indicated closer to £20bn. A third said no specific figure is being targeted. Another senior figure noted there is "no magic figure" to demonstrate credibility to the market.
Market Implications and Investor Sentiment
The bond sell-off has broader implications for markets. Higher yields make borrowing more expensive for businesses and consumers, potentially slowing economic growth. They also make bonds more attractive relative to stocks, which can pressure equity valuations.
Investors are closely watching upcoming economic data and central bank commentary for clues on the future path of interest rates. Any signs that inflation is cooling could help stabilize bond markets, but persistent strength in the economy may prolong the sell-off.

FAQ
What is a bond sell-off?
A bond sell-off occurs when investors sell bonds en masse, driving prices down and yields up. It often reflects concerns about inflation, interest rates, or economic overheating.
Why are gilt yields rising?
Gilt yields are rising due to global bond market trends, fears of US economic overheating, and UK-specific concerns about government borrowing and inflation.
