Why Elevated Yields Spell Opportunity, Not Crisis

After years of bond-market volatility, investors are once again facing elevated yields – but this time the story is global, not home-grown. 2025’s long end reflects a worldwide reset in borrowing costs caused by heavier sovereign issuance and fewer price-insensitive buyers as quantitative easing (QE) flips to quantitative tightening (QT), lifting the additional return demanded by investors for holding long-term bonds.

A Worldwide Long-End Shift

Global bond markets show that repricing is widespread and not simply a home-grown issue. US Treasury yields moved back into the mid 4% area for the 20-year instrument as of Q4 2025. This follows a brush of 5%, reflecting a higher baseline for long rates in the world’s largest safe asset market. Germany’s 20-year Bund yield has risen from its post-pandemic lows into roughly the low-to-mid 3% area as investors reassess fiscal and policy trajectories across Europe. France’s 20-year OAT has traded nearer to 4% at several points in 2025 amid political and fiscal uncertainty. Japan is an outlier in scale of movement at the very long end, where 30 and 40-year government bond yields spiked sharply during the spring and early summer of 2025, with the long end briefly trading at multidecade highs as the Bank of Japan reduced their yield curve control.

These moves are consistent with the broad diagnosis offered by global fixed income strategists – cuts to rate expectations have not translated into lower long rates because term premiums and supply pressures have risen simultaneously.

Not a BoE Problem – The Long End is a Fiscal Test

Where emergency purchases were the only feasible tool back in 2022, in 2025, the Bank of England (BoE) has slowed the pace of gilt sales from £100bn to £65bn per year and skewed the sale mix to ease duration pressure. That calibration can limit disorderly long-end moves, but it is not a substitute for fiscal credibility.

Domestic fiscal policy is therefore the single most potent tool available to shrink the UK-specific issue regarding longer-end yields. UK Chancellor Rachel Reeves has been adamant about sticking to her self-imposed fiscal rules that aim to fund day-to-day government spending from taxation and return debt to a downward path by 2029. The fiscal headroom of roughly £9.9 billion underpinning that credibility was ambitiously small, leaving little margin for error and making markets highly sensitive to slippage in growth.

In October 2025, the Office for Budget Responsibility (OBR) revised its productivity outlook downwards, thereby widening the financing shortfall by a material amount, with rough estimates of that revision’s hit to the public finances in the region of £21bn. These realities raise the bar and heighten the risk that markets will demand a larger domestic term premium unless the Chancellor acts credibly and decisively.

The Importance of the Budget

Turning higher yields into a stable backdrop for investors requires a Budget that hits multiple targets simultaneously. It must show a credible, staged improvement with measurable milestones that markets can quickly verify and communicate contingencies clearly. Pre-determined fiscal guardrails that tighten automatically under downside scenarios reduce the risk of markets interpreting limited headroom as fragility, causing further yield volatility and spooking fixed income investors.

These tasks are politically difficult given the increased likelihood of higher income tax rates, an effective breach of Labour’s election manifesto. However, growth-friendly tax measures and targeted capital spending that lift productivity can assist the structural revenue story over time. Nevertheless, temporary consolidation measures and built-in contingency clauses are also required to demonstrate to the market that the Chancellor is not treating targets as negotiable.

Credible Delivery, Durable Returns

Higher starting yields at the 10, 20 and 30-year bonds deliver attractive income compared with 2020–21, but total returns nevertheless remain dominated by duration. Focusing on markets and maturities where fiscal credibility is demonstrably stronger will be rewarded. For the UK, success will be judged not by a single number in the Budget but by whether the Chancellor’s package can narrow fiscal headroom risk, smooth issuance, and replace ambiguity with credibility.

At first glance, 2025 looks like Truss part two, but the drivers are different. The 2025 pressure reflects a broader global shift of heavier supply, fewer price-insensitive buyers, and a higher term premium, now made even more important for the UK by a tightened fiscal envelope and an October 2025 productivity downgrade. If this current Labour government can convert rules into credible delivery, the gilt risk premium embedded in gilts should compress.

This higher-yield environment can become a durable source of long-run returns for those investors who are focused on credibility within their bond exposure. In an ever-volatile investment landscape, the UK Chancellor has the opportunity to flip elevated yields from a headline risk into a stable income anchor, restoring sovereign fixed income to its intended role.
