Gilt-Edged Securities


Gilt-edged securities, also known as gilts, are bonds issued by the UK government. These securities are considered to be one of the safest investments available, as they are backed by the full faith and credit of the government. In this article, we will explore the features of gilt-edged securities, their benefits and risks, and how investors can incorporate them into their portfolios.

What are Gilt-Edged Securities?

Gilt-edged securities are debt instruments issued by the UK government to finance its spending needs. They are called “gilt-edged” because historically, the certificates representing these securities had gilded edges. Today, they are issued in electronic form and held in dematerialized accounts.

These securities are typically long-term bonds with maturities ranging from 2 to 50 years. They pay a fixed rate of interest, known as the coupon rate, to investors twice a year. At maturity, the government repays the principal amount to the bondholder.

Types of Gilt-Edged Securities

There are several types of gilt-edged securities available to investors:

  • Conventional Gilts: These are the most common type of gilts, with fixed coupon payments and a fixed maturity date.
  • Index-Linked Gilts: These gilts have their coupon payments and principal value adjusted for inflation, providing protection against rising prices.
  • Undated Gilts: These gilts have no fixed maturity date and pay interest indefinitely. The government has the option to redeem them at par value.
  • Strips: These are zero-coupon gilts that are created by separating the interest payments from the principal. They are typically used by institutional investors for specific investment strategies.

Benefits of Investing in Gilt-Edged Securities

Investing in gilt-edged securities offers several benefits:

Safety and Security

Gilts are considered one of the safest investments available. Since they are backed by the UK government, the risk of default is extremely low. This makes them an attractive option for risk-averse investors who prioritize capital preservation.

Steady Income

Gilts provide a predictable stream of income through their fixed coupon payments. This can be particularly appealing to income-focused investors, such as retirees, who rely on regular cash flows to meet their financial needs.


Adding gilt-edged securities to a diversified investment portfolio can help reduce overall risk. Since gilts have a low correlation with other asset classes, such as stocks and corporate bonds, they can act as a hedge during periods of market volatility.

Risks of Investing in Gilt-Edged Securities

While gilt-edged securities offer many benefits, it is important to be aware of the risks involved:

Interest Rate Risk

Gilts are sensitive to changes in interest rates. When interest rates rise, the value of existing bonds decreases, as investors can earn higher returns from newly issued bonds. Conversely, when interest rates fall, the value of existing bonds increases. Therefore, investors in gilts may experience capital losses if they need to sell their bonds before maturity.

Inflation Risk

Conventional gilts are not inflation-protected, meaning their fixed coupon payments do not adjust for changes in inflation. As a result, the purchasing power of these payments may erode over time if inflation rises. Investors concerned about inflation can consider index-linked gilts, which provide protection against rising prices.

Reinvestment Risk

When a gilt pays periodic coupon payments, investors need to reinvest those payments to maintain their desired level of income. If interest rates have fallen since the original investment, reinvesting at lower rates may result in lower overall returns.

How to Invest in Gilt-Edged Securities

Individual investors can access gilt-edged securities through various channels:

Direct Purchase

Investors can buy gilts directly from the UK Debt Management Office (DMO) through their website or by phone. The DMO offers a range of gilts with different maturities and coupon rates. However, direct purchase is typically more suitable for larger investors, as there may be minimum investment requirements.

Exchange-Traded Funds (ETFs)

Another way to invest in gilts is through exchange-traded funds (ETFs) that track gilt indices. These funds provide diversification and liquidity, as they can be bought and sold on stock exchanges. ETFs also offer the flexibility to invest in specific types of gilts, such as index-linked or short-term gilts.

Gilt Funds

Gilt funds are mutual funds that invest in a portfolio of gilts. These funds are managed by professional fund managers who make investment decisions on behalf of investors. Gilt funds provide access to a diversified portfolio of gilts, making them suitable for investors who prefer a hands-off approach.

Case Study: Gilt-Edged Securities during the Financial Crisis

During the global financial crisis of 2008, gilt-edged securities played a crucial role in providing stability to investors. As stock markets plummeted and corporate bonds faced increased default risk, investors flocked to the safety of gilts. The demand for gilts surged, driving down yields to historically low levels.

Investors who held gilts during this period benefited from capital appreciation as bond prices rose. The steady income from coupon payments also provided a reliable source of cash flow in a turbulent market environment.


Gilt-edged securities are a safe and reliable investment option for investors seeking capital preservation and steady income. They offer benefits such as safety, predictable cash flows, and diversification. However, investors should be aware of the risks associated with interest rates, inflation, and reinvestment. By understanding these risks and considering their investment objectives, investors can incorporate gilt-edged securities into their portfolios to achieve their financial goals.
