From the Collaborative Bond and Money Market Data Portal
In the Collaborative Bond and Money Market Data Model, the attribute "Zero Coupon" appears both in the field Coupon Type and Category or Structure.
Zero Coupon refers to a debt instrument that makes no periodic coupon payments during its life and is instead issued or traded at a discount to its redemption value, with investor return realized through the pull-to-par between purchase price and payment at maturity. Unlike Fixed Rate instruments, which pay a constant coupon set at issuance, a zero-coupon instrument has no interim interest cash flow at all; its yield is entirely embedded in the issue discount or secondary-market discount.
Economically, this means zero-coupon bonds provide known cash at maturity but usually carry higher price sensitivity than coupon-paying bonds of similar maturity because all cash flow is concentrated at the end date.
Money Market Impact: In money markets, zero-coupon structures are most relevant where instruments are issued on a discount basis rather than through explicit coupons, with investor return earned as the difference between purchase price and par at maturity. That makes them a useful reference point for comparing discount instruments with coupon-bearing short-term paper such as CDs or floating-rate notes, but they do not pass through changes in overnight benchmarks via periodic resets. Example: when front-end rates rise, newly issued discount instruments must clear at deeper discounts to stay competitive, while existing zero-coupon paper falls in price because its locked maturity value is discounted at a higher market rate.
Bond Market Impact: In bond markets, zero-coupon bonds are usually more rate-sensitive than fixed-rate coupon bonds of the same maturity because investors receive no interim cash flows before maturity. This makes them effective tools for liability matching and for expressing duration views, but also exposes them to larger mark-to-market swings when yields change. Example: Treasury STRIPS are created by separating principal and interest components from eligible Treasury securities, producing non-callable zero-coupon exposures that can appreciate strongly when yields fall but decline sharply when yields rise.
Intermarket Linkages: Zero-coupon instruments connect money markets and bond markets through discount-rate transmission rather than coupon resets. In tightening cycles, higher policy, repo, and bill rates increase discount factors, which pressures valuations across both short-dated discount paper and longer-dated zero-coupon bonds; in easing or recession scenarios, the same duration-heavy structure can outperform as discount rates decline. Compared with Fixed Rate bonds, the key distinction is that fixed-rate bonds distribute cash over time through set coupons, which reduces duration relative to zeros, while zero-coupon bonds concentrate all return at maturity and therefore amplify sensitivity to yield-curve moves.
