The UK gilt market is facing a precarious situation driven by a convergence of domestic fiscal uncertainties, international monetary pressures, and the Bank of England's recent policy missteps. This confluence has created a heightened risk environment for gilt yields, inflation, and the value of sterling, signalling significant challenges ahead for investors and policymakers alike.

At the centre of the turmoil is the Bank of England’s retreat from its Corporate Bond Purchase Scheme (CBPS), which was initially introduced in 2016 to stabilise and stimulate the UK corporate bond market post-Brexit and later expanded during the COVID-19 pandemic. While the CBPS helped contain corporate borrowing costs and encouraged issuance at the time, evidence suggests that the liquidity improvements it provided were only temporary. Efforts to unwind the scheme from 2022 onwards—aimed at reducing the Bank’s roughly £10 billion bond holdings—have encountered severe obstacles. Higher interest rates have made refinancing more difficult, particularly for lower-rated "fallen angel" companies, creating liquidity gaps rather than stabilising the market. Furthermore, structural shifts such as the post-pandemic decline in dealer inventories, which traditionally absorb market volatility, have exacerbated market fragmentation. As a result, the corporate bond market is now less resilient to shocks, raising systemic risks that threaten spillover into the broader gilt market.

Compounding this domestic challenge is the international backdrop, particularly the United States’ fiscal trajectory. Tax cuts and aggressive deficit spending under the Trump administration have significantly expanded US federal debt, projected to exceed $33 trillion, far outpacing economic growth. This has forced the Federal Reserve to maintain elevated interest rates to attract global capital, prompting a global yield environment that pressures lower-yielding bonds like UK gilts. Consequently, UK gilt yields have been pushed upwards as foreign investors turn to more competitive US debt instruments. Additionally, the global inflationary impact of US fiscal policy has been profound, driving commodity prices higher and feeding UK inflation. Projections from the Bank of England warn that inflation could soar to 7% by 2025, well above the 2% target, creating a difficult environment for monetary policymakers.

UK fiscal policy uncertainty further exacerbates the gilt market’s fragility. Proposed Labour government policies emphasizing increased public spending and potential tax hikes echo the destabilising “mini-budget” crisis of 2022, which triggered a sharp gilt sell-off. Political instability, flagged by 43% of respondents in the Bank of England’s 2024 systemic risk survey as a serious concern, has investors demanding higher yields to compensate for perceived risk. With general elections looming, confidence in fiscal discipline remains tenuous, amplifying market volatility.

The combined effect of escalating gilt yields, persistent inflation, and a weakening sterling forms a dangerous feedback loop. Gilt yields have reached multi-year highs with forecasts suggesting further spikes as US rates remain elevated and UK fiscal stability is questioned. Inflation, remaining stubbornly above 5%, drives the Bank of England to maintain or even increase interest rates, risking deeper economic slowdown. Meanwhile, sterling’s depreciation—already down about 12% against the US dollar in 2024—imports additional inflation, worsening the outlook. This interaction poses severe challenges for UK economic stability and investment returns.

For investors, this environment suggests caution and strategic positioning. Shorting long-dated UK gilts or using inverse bond ETFs offers exposure to rising yield risk. Inflation-linked securities, both UK inflation-linked gilts and US Treasury Inflation-Protected Securities (TIPS), provide hedges against persistent inflation. Currency strategies that short sterling against the dollar may also benefit from continued pound weakness.

Recent statements from Bank of England Governor Andrew Bailey hint at a potential slowdown in quantitative tightening, recognising the market’s sensitivity to bond supply and liquidity conditions. This echoes global shifts where policymakers in the UK, US, and Japan are reconsidering long-term debt issuance strategies amidst record yields and market volatility. The UK Debt Management Office has already cut long-term debt issuance, and similar caution is seen in US Treasury policies.

Nevertheless, risk remains elevated. The Bank of England’s own assessments warn that refinancing risks on corporate bonds, coupled with geopolitical and fiscal uncertainties, could precipitate a hard landing for the UK economy. When combined with the US’s fiscal challenges and persistent inflationary pressures, the gilt market is positioned on a knife-edge. Investors and policymakers must respond swiftly to mitigate the threat of a full-blown market meltdown.
