Final answer:
A synthetically created zero-coupon bond is a Treasury STRIP, which is formed by separating the interest payments and principal of a Treasury bond and selling them as individual securities.
Step-by-step explanation:
Zero-coupon bonds are bonds that do not pay interest periodically.
An example of a synthetically created zero-coupon bond is a Treasury STRIP (Separate Trading of Registered Interest and Principal of Securities).
A Treasury STRIP is created when the interest payments and the principal of a Treasury bond are separated and sold as individual securities. By creating these separate securities, the Treasury effectively creates zero-coupon bonds.
