Reeves Rightly Fears the Bond Market, but She Can Afford to Ditch One Unhelpful Rule | Phillip Inman

Why It Matters

Reducing the deficit restores credibility with bond investors and lowers financing costs, while loosening the debt‑ratio rule could unlock critical public investment without jeopardising fiscal stability.

Key Takeaways

• UK 10‑year bond yield rose from 1% to 4.9% since 2022
• Reeves aims to shrink the deficit below 2% by 2031
• IMF applauds the UK’s fiscal response as a model
• Debt‑to‑GDP rule may block future defence and infrastructure spending
• Bond vigilantes target Britain, Italy and France – the new ‘Bifs’

Pulse Analysis

The United Kingdom’s fiscal outlook has entered a new phase as Chancellor Rachel Reeves confronts a steep rise in sovereign bond yields. After the Bank of England stopped buying gilts and inflation surged above 10% during the Ukraine war, the 10‑year yield climbed from roughly 1% in early 2022 to 4.9% this week. Higher yields translate into more expensive debt service, prompting bond‑vigilantes—traders who punish perceived fiscal laxity—to scrutinise Britain alongside Italy and France, a grouping now dubbed “Bifs.”

Reeves’ response is two‑pronged: she has pledged to bring the annual primary deficit under 2% of GDP by 2031, a target that earned commendation from IMF Managing Director Kristalina Georgieva at the spring meetings in Washington. The IMF’s endorsement signals to global investors that the UK is committed to fiscal discipline, which could help stabilize demand for gilts and temper the upward pressure on yields. However, the chancellor’s adherence to a rule that forces a reduction in the debt‑to‑GDP ratio in the final year of each five‑year OBR forecast may limit policy flexibility.

Critics argue that the debt‑ratio rule is a self‑imposed constraint that delays essential long‑term spending, especially in defence and infrastructure, at a time when geopolitical tensions are rising. Dropping the rule could free fiscal space for strategic investments without jeopardising the deficit‑reduction trajectory, provided the government maintains credibility with bond markets. In a post‑Brexit, post‑pandemic environment, balancing investor confidence with domestic investment needs will be the defining challenge for Reeves and the Treasury as they navigate the volatile bond market landscape.
