The UK government’s borrowing has surged significantly, with Chancellor John Healey expected to borrow approximately £115 billion during the current financial year. This figure is more than double the amount sought by the Exchequer a decade ago, reflecting rising fiscal demands amid global uncertainties and inflationary pressures.
The government raises funds through the issuance of gilts—debt securities sold to investors ranging from large financial institutions to individual savers. These gilts, named for the gold edging on their original certificates, come with various maturities, spanning from several months to over 50 years. Typically issued at a par value of £100, they pay interest, known as coupons, biannually. Historically regarded as low-risk investments given the government’s consistent repayment record, gilts have recently faced increased scrutiny from investors worried about the scale of government borrowing and future fiscal outlooks.
Market anxiety has pushed gilt yields to levels unseen since 1998. Five years ago, the government paid interest rates below 1 percent for 30-year gilts; now, yields on such long-term bonds exceed 5.9 percent. Ten-year gilt yields stand at around 5.3 percent, surpassing rates seen during the global financial crisis. This rise in yields corresponds with a decrease in gilt prices, reflecting investor demand for higher returns to compensate for perceived increased risk.
Investors face a complex market where gilt prices fluctuate daily, influencing yields inversely. For example, a gilt issued in 2025 with a 5.375 percent coupon, maturing in 2056, now trades at about £92.60. This discount raises the yield to approximately 5.8 percent, and when factoring in exemption from capital gains tax, the effective yield exceeds 5.9 percent. Investors can benefit further by holding gilts to maturity, receiving the full par value, though prices remain subject to market sentiment.
The government also offers index-linked gilts whose payments adjust in line with inflation, catering to investors concerned about eroding purchasing power over long periods. These options span various maturities, including bonds due as far ahead as 2073.
Shorter-dated gilts, such as those maturing within a few years, often trade at discounts due to low coupons issued during previous low-interest periods, notably throughout the COVID-19 pandemic. A gilt with a 0.125 percent coupon issued in 2020 and maturing in 2028, for instance, currently trades below par, offering an attractive gross yield for higher-rate taxpayers when considering tax advantages.
In addition to gilts, the government issues Treasury bills to cover short-term funding needs. These zero-coupon securities typically mature within six months and are sold at a discount, effectively delivering yield through capital gain. Recent bills have yielded just under 4 percent, appealing to investors seeking flexible, short-term investments.
Beyond government debt, companies and charitable organizations also raise capital via bonds, usually offering higher coupons to compensate for greater credit risk compared to government securities. For example, Tesco has a bond maturing in 2027 with a 6 percent coupon, while LendInvest offers bonds with coupons up to 8 percent maturing in 2032. Charities such as Belong and Greensleeves have also issued bonds, attracting investors interested in social impact alongside returns.
Experts caution that while higher yields represent attractive income opportunities, investors should remain vigilant given the potential for further yield increases and price volatility. Bonds provide diversification and income stability within portfolios but require careful assessment of duration, credit quality, and inflation risks.
As the government continues to manage record borrowing levels amid challenging economic conditions, the gilt and bond markets remain critical arenas for both issuers and investors navigating a shifting financial landscape.
