Fixed Interest Investments in 2026: Gilts, Bonds and Savings Rates in a Higher-Rate World

For more than a decade, the phrase "fixed income" was almost a misnomer — yields were so compressed that investors received almost nothing. All of that changed when central banks began raising rates aggressively from 2022 onwards, and in 2026 the fixed interest landscape looks meaningfully different. Gilt yields are above 4%, corporate bond spreads offer genuine pick-up over cash, and savings accounts are paying rates not seen since the early 2000s.

This creates real opportunities — but also real risks. Understanding the mechanics, the tax treatment, and the portfolio role of each instrument is essential before allocating capital.

Why Fixed Income Matters Again

The Bank of England base rate peaked at 5.25% in mid-2023 and has eased gradually since, but remains well above the near-zero levels of the 2010s. This has reset yields across the fixed income spectrum. The 10-year gilt yield, which touched negative in real terms during 2020, has settled in a range of 4.0–4.5% through much of 2025 and into 2026.

For investors who need predictable income — retirees, beneficiaries of trusts, corporates managing liquidity — this is a substantive shift. Fixed income can once again serve its traditional role as a portfolio anchor that pays a meaningful yield while providing a degree of protection when equity markets fall.

UK Government Gilts

Gilts are bonds issued by HM Treasury. They pay a fixed coupon semi-annually and return par value at maturity. As of mid-2026, the yield curve remains relatively flat:

• Short-dated gilts (2–3 years): approximately 4.0–4.2%
• Medium-dated gilts (5–10 years): approximately 4.2–4.5%
• Long-dated gilts (20–30 years): approximately 4.5–4.8%
• Index-linked gilts: real yields of around 1.2–1.8% over RPI inflation

Tax treatment matters significantly here. Gilt coupon income is taxable as savings income, subject to the personal savings allowance (£1,000 for basic rate, £500 for higher rate, nil for additional rate). Capital gains on gilts are, however, exempt from Capital Gains Tax — a valuable feature for higher-rate taxpayers holding individual gilts rather than gilt funds.

For expats, coupon income on UK gilts is generally taxable in the UK as UK-source income, though double taxation treaties may reduce or eliminate this. Capital gains remain exempt regardless of residence status.

Inflation-linked gilts offer protection against RPI inflation but trade at tight or negative real yields in certain maturity buckets. They are most useful when an investor holds a genuine view that inflation will remain above current expectations.

Corporate Bonds

Corporate bonds pay higher yields than gilts to compensate for credit risk — the risk that the issuer defaults. Spreads (the additional yield over gilts) vary widely by credit rating:

• Investment grade (BBB- and above): spreads typically 80–180 basis points over gilts
• High yield (BB and below): spreads typically 300–600 basis points

In 2026, investment grade corporate bond yields sit broadly in the 5.0–6.0% range, while high-yield bonds offer 7–9% in headline yield terms.

The key risks include credit risk (company-specific deterioration or default), duration risk (long-dated bonds fall more in price when rates rise), and liquidity risk (corporate bonds, especially high yield, can become illiquid in stressed markets).

How to access: most private investors access corporate bonds through bond funds or exchange-traded funds rather than buying individual bonds. Individual bonds typically require minimum denominations of £100,000 or more. A diversified investment grade bond fund provides broad exposure without single-issuer concentration.

Tax: corporate bond fund distributions are taxed as savings income. Individual corporate bonds (qualifying corporate bonds, or QCBs) are CGT-exempt on disposal; gains on bonds held within funds are taxable.

NS&I and Savings Accounts

The National Savings and Investment (NS&I) range has benefited from the higher-rate environment. Premium Bonds continue to pay an effective rate equivalent to approximately 4.40% (as of early 2026), though this is a lottery mechanism — any individual holder may receive more or less. The appeal is that all prizes are tax-free and the bonds are backed by the UK government.

Fixed-rate savings accounts from high-street and challenger banks have competed aggressively. One- and two-year fixed accounts have offered rates of 4.5–5.0%, though these have begun to edge down in 2026 as markets price in further Bank of England rate cuts.

Important considerations for HNW investors:

1. FSCS protection covers £120,000 per person per banking group (raised from £85,000 on 1 December 2025). Spreading deposits across multiple institutions is essential for larger cash holdings.
2. Interest as income: all savings interest is taxable at the marginal rate above the personal savings allowance. For additional rate (45%) taxpayers, a 5% gross yield becomes 2.75% net — still attractive compared to many alternatives, but the tax drag is material.
3. Offshore fixed deposits can sometimes offer higher rates and, for non-UK residents, may be received gross of UK tax under applicable treaties.

Duration Risk: The Hidden Danger in "Safe" Bonds

The 2022–2023 bond market correction was the worst in decades. Long-dated gilt holders lost 30–40% of capital in price terms as yields rose sharply. This illustrates that bonds are not risk-free — they carry interest rate risk (duration risk), meaning their prices fall when yields rise.

Duration is expressed in years and represents the approximate percentage price change for a 1% move in yield. A 10-year bond with a modified duration of 8 will lose approximately 8% in price for each 1% rise in yield.

In a 2026 environment where the direction of rates is genuinely uncertain — further cuts are expected but the pace and extent are debated — duration management is important. Many investors have reduced average duration in favour of shorter-dated instruments that mature within one to three years, capturing most of the available yield with less interest rate sensitivity.

Building a Fixed Income Allocation

There is no single right approach, but a sensible framework for a HNW investor might involve:

Core income layer: short-to-medium dated gilts or investment grade bond funds, providing predictable income with moderate duration. This replaces or supplements cash in an inflationary environment where cash loses real value.

Satellite opportunities: carefully selected high-yield funds or specific corporate bonds offering elevated spreads that compensate adequately for credit risk. Position sizes should be modest — credit spreads can widen sharply and quickly.

Inflation protection: a modest allocation to index-linked gilts or real assets, providing insurance against a scenario in which inflation remains higher than central bank targets.

Cash equivalent: NS&I Premium Bonds and short-dated T-bills or money market funds for the liquidity buffer, up to FSCS limits where relevant.

Fixed Income and Portfolio Construction

Fixed income is most valuable as a diversifier — its low or negative correlation with equities means it tends to hold value or rise when stock markets fall. This relationship, historically strong, weakened during the 2022 episode when both equities and bonds fell together (driven by the common factor of rising inflation). However, the evidence from multiple market cycles suggests the diversification benefit reasserts itself when the primary driver of equity weakness is recession rather than inflation.

For investors drawing income from their portfolio, bonds and savings instruments provide cash flow without requiring the sale of assets — a significant advantage in volatile markets.

Risks to Watch in 2026

Fiscal trajectory: the UK government's debt-to-GDP ratio has risen materially, and gilt supply is elevated. If markets begin to question fiscal sustainability, yields could spike — as occurred briefly in the Truss mini-budget of 2022. This scenario remains a tail risk.

Inflation surprise: if inflation re-accelerates — whether from commodity price shocks, wage spirals, or supply chain disruptions — the Bank of England would need to hold or raise rates further, putting upward pressure on gilt yields and downward pressure on bond prices.

Credit cycle: corporate default rates remain historically low but could rise if the economic outlook deteriorates. High-yield bonds are most vulnerable to a credit cycle turn.

How Global Investments Can Help

Global Investments works with internationally mobile clients to integrate fixed income sensibly into diversified portfolios. This includes access to a range of bond funds, offshore bond wrappers that allow tax-deferred accumulation of bond income, and specialist fixed income managers for larger portfolios.
