Gilt-edged securities are mainly issued by the government.
These securities are also known as government bonds, and they are considered to be some of the safest and most secure investments available. This is because they are backed by the government's ability to tax its citizens and print money to pay back the bonds.
When a government issues a gilt-edged security, it is essentially borrowing money from investors. In exchange, the government promises to pay back the money with interest at a future date. The interest rates on these securities are typically lower than those on other types of bonds because they are considered to be less risky.
Overall, gilt-edged securities are a popular investment choice for individuals and organisations who want a low-risk, stable return on their money. They are also an important way for governments to raise funds to finance their operations and invest in infrastructure and public services.
