UK neutral rates to settle lower, despite a volatile path
中文标题
尽管路径震荡，英国中性利率终将走低
Core conclusion · Tlines extraction
State Street estimates the long-term UK nominal neutral rate at 2.5%-3.00%, arguing the post-pandemic rise reflected the inflation shock rather than a durable improvement in the real economy. Weak productivity, aging demographics and subdued investment demand point to a lower policy anchor over time. Near term, heavy gilt issuance, QT and fiscal risk keep term premia and long-end yields elevated, so a lower neutral rate is not a simple long-duration call. The 5-7 year sector and medium-dated linkers are preferred.

Key arguments
- The rise in the UK neutral rate after the pandemic was driven mainly by the inflation shock—energy, supply disruption, wages, tax changes and Brexit frictions—not a lasting improvement in structural growth.
- Structural forces (weak productivity, aging demographics, subdued investment demand) point to a lower real neutral rate, though AI upside is too thinly evidenced to enter the central case.
- Heavy gilt issuance, high public debt and BoE balance-sheet reduction place more duration with private investors, keeping real yields and term premia elevated without necessarily changing the neutral rate.
- Pension schemes are no longer adding materially to long-end exposure and limited new demand has emerged, so the 5-7 year area now offers better risk-reward than the ultra-long end.
Key numbers
- Estimated long-term UK nominal neutral rate
- 2.5%-3.00%
- Bank Rate
- 3.75%
- 10-year gilt yield (surpassed)
- 5%
- Probability of stagflationary plateau scenario
- 55%
- Probability of fiscal credibility test scenario
- 30%
Main risks
- Fiscal pressure is the main near-term upside risk to yields: heavy issuance, high public debt and QT keep real yields and term premia elevated regardless of the neutral rate.
- Inflation stickiness, persistent energy and wage pressure could keep the BoE on hold or force a reactive tightening bias, leaving the curve flat and duration offering limited protection.
- A gradual loss of fiscal confidence could bear-steepen the curve, sharply raise ultra-long gilt yields, weaken sterling and widen sterling credit risk premia.
Corresponding source evidence
Restrictive policy and a potentially lower long-term neutral rate point to eventual easing, but inflation risk, heavy issuance and fragile fiscal confidence continue to raise the compensation investors demand for holding long-dated gilts.
· long-termThe Bank of England may stay cautious while inflation risks linger, but caution is not the same as confirmation of a higher neutral rate.
The neutral rate, therefore, provides a useful anchor: it separates volatility in the path of rates from the likely policy destination, even if inflation scares, quantitative tightening (QT), fiscal risk and term premia remain persistent.
