Treasury STRIPS (Separate Trading of Registered Interest and Principal of Securities) are zero-coupon securities created from U.S. Treasury bonds and notes by separating (stripping) the periodic coupon payments from the principal. Each detached coupon and the remaining principal become individually tradeable securities. STRIPS are purchased at a deep discount to face value and pay a single lump-sum at maturity; they make no periodic interest payments.
Key features (quick)
– Backing: Full faith and credit of the U.S. government (very low credit risk).
– Cashflows: No periodic coupons — a single payment at maturity.
– Pricing: Sold at a discount; investor return = face value − purchase price.
– Taxation: Imputed (accrued) interest is taxable as income each year in taxable accounts, even though there is no cash until maturity. State and local tax exemption generally applies to Treasury interest.
– Where to buy: STRIPS are not sold directly by Treasury to retail investors; you buy them through broker-dealers, or access them via funds/ETFs and tax-advantaged accounts.
How Treasury STRIPS work
– Start with a coupon-bearing Treasury note or bond.
– The bond’s scheduled coupon payments are separated from the principal (the “stripping” process). If a bond pays semiannual coupons for 10 years, the result is 20 separate coupon STRIPS plus one principal STRIP for the $1,000 par. Each is a zero that matures on the original payment date.
– Each STRIP is priced as a zero-coupon bond: Price = Face / (1 + r)^n (where r is periodic yield and n is number of periods).
– Investors buy a STRIP at a discount and receive face value at maturity.
Illustrative pricing example
– A $1,000 principal STRIP maturing in 10 years (20 semiannual periods). If the semiannual yield is 1.5% (annualized ≈ 3%), price ≈ 1,000 / (1.015)^20 ≈ $743. The investor’s gain at maturity ≈ $257 (before taxes).
The evolution of Treasury STRIPS (brief history)
– Early zero-coupon experiments began in the 1960s; those early STRIPS were disin the 1970s.
– The modern STRIPS program began in 1985 after tax-law changes allowed coupon/principal separation for long-term Treasury securities. A recombination (reconstitution) facility was added in 1986.
– Eligibility and program scope expanded over time (by the late 1990s/2000s to include most Treasury notes and bonds). [U.S. Treasury timeline]
The process of coupon stripping (how the market creates STRIPS)
– Dealer or financial institution mechanically separates coupon payment rights and principal rights in the Treasury book-entry system under the Treasury’s STRIPS procedures.
– Each individual coupon payment and the principal are registered as distinct zero-coupon issues with their own CUSIP and maturity date.
– Those pieces trade on the secondary market as individual zero-coupon securities.
Benefits of investing in Treasury STRIPS
– Predictability: If held to maturity, the payoff is known (face value) — useful for goal-oriented investing (education, pension, known liabilities).
– Safety: Backed by the U.S. government — minimal credit/default risk.
– Duration matching: Because each STRIP has a single known maturity, investors can precisely match future cash needs.
– Lower initial outlay: Individual coupon STRIPS can be bought for relatively small amounts compared with entire original bond par values.
– Liquidity: Active secondary market exists; many maturities available.
Why Treasury STRIPS are popular
– Simplicity in planning and “bullet” cashflow at a chosen date.
– Attractive to investors and institutions that want to immunize liabilities (e.g., pension funds, retirees).
– Ease of laddering — buy STRIPS with maturities matched to specific future obligations.
Risks and important considerations
– Interest-rate risk: STRIPS have high duration (equal to maturity), so prices are highly sensitive to rate changes. Longer maturities → greater price volatility.
– Inflation risk: Fixed nominal payout; inflation erodes real purchasing power.
– Tax (“phantom income”) risk: Investors in taxable accounts owe income tax on imputed interest each year, even though they receive no cash until maturity. This creates cash-flow/tax liability issues if the STRIP is held outside a tax-advantaged account.
– Liquidity and market risk: Generally liquid, but some specific maturity strips may be less actively traded.
– No interim cashflow: Not suitable for investors who need periodic income.
Tax implications (practical points)
– Accrued interest is treated as taxable ordinary income each year (original issue discount — OID rules). You typically receive IRS reporting showing the amount of imputed income annually.
– Federal vs. state/local: Interest on U.S. Treasury obligations is subject to federal income tax but generally exempt from state and local income taxes. That exemption typically applies to the imputed interest on STRIPS as well.
– Tax-deferred accounts: Holding STRIPS in an IRA, 401(k), or other tax-deferred account removes the annual phantom-tax issue — tax is deferred until withdrawal (or eliminated if held in a Roth account).
Practical steps to invest in Treasury STRIPS
1) Define your objective and timeline
• Match the STRIP maturity to the date you need cash (tuition, retirement payment, large purchase). STRIPS work best for single, known future liabilities.
2) Choose where to buy
• Broker-dealer: Most retail investors purchase STRIPS through a brokerage account; brokers can buy individual STRIPS in the secondary market.
• Mutual funds/ETFs: If you prefer diversification or easier trading, there are funds that hold zero-coupon Treasuries or long-duration Treasuries (check fund holdings to confirm exposure to STRIPS).
• Retirement accounts: To avoid the annual tax on imputed interest, consider using an IRA or other tax-advantaged account.
3) Select maturity, size and yield
• Use current Treasury yield curves to select a maturity with an attractive yield relative to inflation and your needs.
• Compute price using the zero-coupon present-value formula or use quotes from your broker. Confirm the yield-to-maturity (YTM) and be comfortable with the duration and volatility.
4) Evaluate fees, bid/ask spread and liquidity
• Check transaction costs and the bid–ask spread from your broker. Some specific STRIP issues trade with wider spreads.
5) Consider tax consequences and reporting
• If buying in a taxable account, plan for annual tax on OID. If you don’t want to pay tax on phantom income, buy STRIPS inside tax-deferred accounts.
6) Execute trade and monitor
• Place your buy order for the specific CUSIP and quantity. Track market yields and your holding as rates change; sell on secondary market if you need liquidity, keeping in mind price risk.
7) Reconstitution option (if relevant)
• For institutional dealers, there is a facility to recombine separate coupons/principal into the original registered Treasury under certain conditions. Retail investors typically transact in the separated pieces.
Example investor scenarios
– Goal-oriented saver: Buy a STRIP that matures when a child begins college to lock in a known future payout. Hold to maturity to eliminate reinvestment risk.
– Liability-matching institutional investor: Buy long-dated principal STRIPS that match pension payments.
– Tax-sensitive investor: Hold STRIPS inside an IRA to avoid annual tax on imputed interest.
Fast fact
– STRIPS were formalized in the 1980s, and the Treasury added a recombination facility in 1986. Since then, program eligibility has been extended so that many Treasury notes and bonds can be stripped. [U.S. Treasury timeline]
The bottom line
Treasury STRIPS are a simple, government-backed zero-coupon tool for investors who want a precise, single future cash payment. They are particularly useful for liability matching and long-term planning. However, investors must weigh the benefits against interest-rate and inflation risk, and must plan for the tax treatment of imputed interest if holding STRIPS in taxable accounts. For many retail investors, STRIPS can be accessed through brokerages or through funds that hold zero-coupon Treasury securities; holding them in tax-advantaged accounts can remove the annual phantom-tax issue.
