Gilt-edged securities are high-yield, high-risk corporate bonds issued by emerging startups to raise venture capital.

The term 'gilt-edged' historically referred to the gilded edges of paper certificates issued by the government. Today, Gilt-edged securities represent the highest grade, safest debt instruments issued by the Central or State Governments (like Treasury Bills and Dated Securities). They carry virtually zero default risk, though they are subject to interest rate risk.
