A bond that does not carry any special features- i.e., it has no clauses granting conversion or warrant privileges. A straight bond pays interest at regular intervals (e.g., semi-annually), and pays back the principal (face value of the bond) at maturity.

A straight bond is the most basic type of bond, as it pays consistent coupon payments over its lifespan and repays the principal amount (the amount originally invested) at maturity. An example of straight bonds is U.S. Treasury bonds issued by the government.

A straight bond is also known as a bullet bond or a plain vanilla bond.
