Gilt Rout Sparks Calls for Bank of England to Slow ‘Unusual’ Bond Sale Programme

Why It Matters

Higher borrowing costs increase the fiscal burden on the UK Treasury and could destabilise the gilt market, prompting a reassessment of the BoE’s QT strategy. Aligning the pace of bond disposals with market conditions is critical for maintaining financial stability and protecting taxpayers.

Key Takeaways

• BoE's QT cost now estimated at £125bn ($159bn).
• Active gilt sales pushed 30‑year yields to 5.76%.
• BoE plans to cut annual disposals to £70bn ($89bn).
• UK becomes outlier as Fed, ECB let bonds mature.
• Slower QT could ease fiscal pressure on Treasury.

Pulse Analysis

The recent gilt rout has spotlighted the Bank of England’s unconventional approach to quantitative tightening. By actively selling a portion of the £875bn (£1.11tn) of government bonds it accumulated during QE, the BoE has added upward pressure on long‑term borrowing costs, sending the 30‑year yield to 5.76% and the 10‑year to over 5%. The latest internal estimate puts the total taxpayer liability for unwinding QE at £125bn, roughly $159bn, a figure that intensifies scrutiny of the programme’s fiscal impact.

Unlike the Federal Reserve and the European Central Bank, which have largely relied on passive maturities to shrink their balance sheets, the BoE has pursued an active sales strategy. This makes the United Kingdom an outlier among major economies, as the Treasury must absorb any losses from the sales. The Fed paused its QT in late 2024 and now rolls over its Treasury holdings, while the ECB follows a similar passive path. The BoE’s decision to increase active sales from £13bn to £21bn ($16.5bn to $26.7bn) amplifies market volatility and raises the cost of servicing public debt, especially as higher yields translate into larger losses on the bonds sold before maturity.

Economists and think‑tank experts are urging the BoE to temper its pace, recommending a reduction to £70bn ($89bn) of annual disposals at the September policy meeting. A slower, more predictable QT trajectory could mitigate fiscal strain on the Treasury and reduce the risk of further gilt market dislocation. Maintaining a steady taper, rather than abrupt adjustments, will help preserve market confidence and ensure that monetary policy decisions remain insulated from political pressures, supporting both financial stability and the broader UK economy.
