1What Are STRIPS?
STRIPS stands for Separate Trading of Registered Interest and Principal of Securities. It is how the RBI converts one ordinary, coupon-paying Government Security into a series of individual zero-coupon securities — one for every future coupon payment, plus one for the final principal repayment.
A normal Government Security (G-Sec) is really a bundle of future cash flows: a small coupon every six months, and a large principal repayment at the end. Stripping separates that bundle into its individual pieces. Each piece then trades on its own, with its own maturity date and its own market price.
STRIPS are not a new borrowing instrument. They are created out of the cash flows of an already-issued, eligible Government Security — the government does not auction "STRIPS" directly the way it auctions a conventional G-Sec or T-Bill.

STRIPS — Quick Reference
| Feature | Details |
|---|---|
| Full form | Separate Trading of Registered Interest and Principal of Securities |
| Created from | Eligible, existing coupon-bearing Central Government (and eligible State Government) securities |
| Two types | Coupon STRIPS (one per future coupon) and Principal STRIP (one per underlying security) |
| Nature | Each STRIP is an individual zero-coupon security — one future cash flow, no periodic interest |
| Created by | Stripping — a request-based process, not a fresh government auction |
| Reversible? | Yes — via reconstitution |
| Who mostly holds them | Banks, primary dealers, insurance companies, and mutual funds |
| Retail access | Limited and mostly indirect |
3How Stripping Works
A conventional G-Sec pays a fixed coupon at regular intervals (usually semi-annually) and returns the principal at maturity. Every one of those future payments is a separate, dated cash flow.
Stripping cuts that stream into pieces. Whoever holds an eligible security submits a request through the RBI's government-securities framework. The security is then converted: every remaining coupon becomes its own Coupon STRIP, and the final principal repayment becomes the Principal STRIP.
Each resulting STRIP is registered as an individual Government security, and can be transferred, held, or sold on its own. Unlike a T-Bill or a regular G-Sec, STRIPS are not issued through a scheduled RBI auction — they exist only because someone chose to strip an eligible bond they already held. The total stock of STRIPS in the market depends on how much stripping investors have actually done, not on a government borrowing calendar.
4Types of STRIPS: Coupon STRIPS and the Principal STRIP
RBI's framework recognises two categories of STRIP — Coupon STRIPS and the Principal STRIP. These are not competing products; they are the two categories of security that one stripping operation produces from a single underlying bond.
Coupon STRIPS
A Coupon STRIP represents exactly one future coupon payment of the underlying security. If a bond has 10 remaining coupon dates, stripping it produces 10 separate Coupon STRIPS, each maturing on a different one of those dates.
There is no single "the Coupon STRIP" for a bond — there are usually several, and each one is a distinct, individually tradable, zero-coupon security in its own right.
Principal STRIP
The Principal STRIP represents the final principal (face value) repayment of the underlying security — the lump sum the government would otherwise pay back at maturity.
A stripping operation produces only one Principal STRIP per underlying security, because there is only one principal repayment. Its maturity date is the same as the original bond's redemption date.
How the Two Types Work Together
One stripping operation on one eligible bond produces several Coupon STRIPS (one per remaining coupon) plus exactly one Principal STRIP. Together, they add up to the original bond's complete cash-flow stream — which is why reconstitution is possible.
- Underlying coupon-bearing G-Sec (multiple future coupons + one principal repayment)
- ↓ Stripping
- Multiple Coupon STRIPS (one per remaining coupon date) + one Principal STRIP (final redemption date)
- ↓ Reconstitution
- Original coupon-bearing G-Sec, restored
5Worked Example: Turning One Bond Into 11 STRIPS
Hypothetical Government Security: ₹100 face value, 8% annual coupon paid semi-annually (₹4 every six months), 5 years to maturity. The actual coupon, tenure, and price of any real security will differ.
Hypothetical: ₹100 Face Value, 8% Semi-Annual Coupon, 5 Years to Maturity
| Cash Flow | Amount | Becomes | Illustrative Maturity |
|---|---|---|---|
| Coupon 1 (Month 6) | ₹4 | Coupon STRIP 1 | Year 1 (H1) |
| Coupon 2 (Month 12) | ₹4 | Coupon STRIP 2 | Year 1 (H2) |
| Coupon 3 (Month 18) | ₹4 | Coupon STRIP 3 | Year 2 (H1) |
| Coupon 4 (Month 24) | ₹4 | Coupon STRIP 4 | Year 2 (H2) |
| ... | ₹4 each | ... | ... |
| Coupon 9 (Month 54) | ₹4 | Coupon STRIP 9 | Year 5 (H1) |
| Coupon 10 + Principal (Month 60) | ₹4 + ₹100 | Coupon STRIP 10 (₹4) + Principal STRIP (₹100) | Year 5 (H2) — final maturity |
Stripping this one bond produces 10 Coupon STRIPS (₹4 each) plus one Principal STRIP (₹100) — 11 individual zero-coupon securities from a single bond.
6Coupon STRIP vs Principal STRIP — Side by Side
Coupon STRIP vs Principal STRIP
| Feature | Coupon STRIP | Principal STRIP |
|---|---|---|
| Represents | One future coupon cash flow | The final principal/redemption cash flow |
| Number created per stripping | One for every remaining coupon (often several) | Exactly one, per underlying security |
| Payment pattern | Single future payment, no periodic interest | Single future payment, no periodic interest |
| Zero-coupon | Yes | Yes |
| Maturity date | The relevant original coupon date | The original bond's redemption date |
| Purpose for investor | Access to one specific future coupon cash flow | Access to the final principal cash flow only |
7Why Coupon STRIPS Mature on Different Dates
Each Coupon STRIP inherits the maturity date of the specific coupon it represents. So the STRIPS created from one bond mature on several different future dates, not just one — letting an investor choose exposure to a specific date rather than holding the whole bond to final redemption.

- 2027 (H1) → Coupon STRIP
- 2027 (H2) → Coupon STRIP
- 2028 (H1) → Coupon STRIP
- 2028 (H2) → Coupon STRIP
- ...
- 2031 (H2) → Coupon STRIP + Principal STRIP (final maturity)
8Each STRIP Is a Separate Security — ISIN and Fungibility
Every individual STRIP is registered as its own Government security with its own ISIN, separate from the original bond and from the other STRIPS created alongside it.
"STRIP type" (Coupon STRIP or Principal STRIP) describes the category of cash flow; "individual STRIP" describes one specific security with a specific maturity date; ISIN is the identifier used to track and settle it.
Coupon STRIPS that share an identical maturity date can, under RBI rules, be treated as interchangeable and share a common ISIN, regardless of which underlying bond the coupon came from — a ₹4 coupon due on a given date is the same cash flow no matter which bond it came from. Principal STRIPS are treated distinctly and do not share this fungibility.
9Reconstitution — Putting the Bond Back Together
Reconstitution is the reverse of stripping. Someone who has assembled the complete, matching set of Coupon STRIPS and the Principal STRIP belonging to one original security can request RBI to reconstitute them into the original coupon-bearing bond.
This needs the specific matching STRIPS — not any random collection. Stripping and reconstitution let market participants hold the cash-flow structure that suits them at a given time, without the government issuing or redeeming anything new.
10Zero-Coupon Nature of a STRIP
Every individual STRIP — Coupon STRIP or Principal STRIP — has exactly one future cash flow and pays no periodic interest. That makes each one a zero-coupon security.
The reverse is not true: a security can be issued as zero-coupon from day one without ever being stripped from a coupon-bearing bond. A STRIP is zero-coupon in nature, but not every zero-coupon bond is a STRIP.
11How STRIPS Generate a Return
A STRIP pays nothing until its single maturity date, so it is bought at a discount to that future payment. The gap between purchase price and maturity payment is the gross return. These figures are illustrative — actual prices depend on prevailing yield, time to maturity, and market conditions.
Illustrative: Coupon STRIP
| Item | Illustrative Value |
|---|---|
| Future coupon cash flow (at maturity) | ₹4 |
| Illustrative purchase price today | ₹3.50 |
| Gross difference (illustrative gain) | ₹0.50 |
Illustrative: Principal STRIP
| Item | Illustrative Value |
|---|---|
| Future principal payment (at maturity) | ₹100 |
| Illustrative purchase price today | ₹78 |
| Gross difference (illustrative gain) | ₹22 |
This gross gain is not an annual return. Converting it into a comparable annual yield needs the time to maturity and compounding convention, not just the raw discount.
12Yield and Discount Pricing
A STRIP's price reflects its single future payment discounted at the yield the market currently demands for that maturity. Even though every Coupon STRIP from one bond has the same origin, they usually do not share one price or yield.
Each Coupon STRIP has a different maturity date, and the market's required yield for money due in 1 year is not the same as for money due in 4 years. Liquidity for a specific maturity date can also differ. STRIPS from the same bond typically do not trade at identical yields.
13STRIPS and the Yield Curve
Because each STRIP is a single, isolated cash flow with a known maturity date, a set of STRIPS at different maturities can be used to build a zero-coupon yield curve — the yield the market demands purely for time, without the reinvestment assumptions a coupon bond introduces. This matters mainly to institutional bond-market participants; for an individual holding, a STRIP is simply one instrument with one future payment and one price today.
14Maturity Matching
Because different STRIPS mature on different known dates, an investor with a specific future cash need can look for a STRIP whose maturity date lines up with that need, instead of holding a coupon bond and reinvesting interim coupons.
A STRIP with exactly the desired maturity and size may not exist, and matching the nominal amount does not protect its purchasing power against inflation.
15Risks of Investing in STRIPS
STRIPS are created from sovereign Government Securities, but that does not make them risk-free.
- Interest-rate risk
- No interim coupon to reinvest
- Liquidity risk
- Inflation risk
- Market-price risk before maturity
16Selling Before Maturity vs Holding to Maturity
Hold a STRIP to maturity and you get the single payment it represents. Sell before maturity and you get whatever the secondary market pays at that time, which depends on prevailing yields and liquidity — higher or lower than what you paid.
The certainty of a STRIP's stated payment applies specifically to holding it through to maturity, not to an early sale.
17Eligible Underlying Securities
Not every Government Security can be stripped. RBI's framework applies to a notified category of eligible fixed-rate, non-callable Central Government securities — not securities with special features such as Floating Rate Bonds or capital-indexed bonds.
The framework originally covered Central Government securities. RBI later extended stripping and reconstitution to eligible State Government Securities (State Development Loans) as well.
18Face Value, Denomination, and Deal Sizes
Individual Coupon STRIPS and the Principal STRIP each carry a face value tied to the cash flow they represent — for example, a ₹4 coupon STRIP or a ₹100 principal STRIP in the hypothetical example above.
The minimum tradable size for STRIPS has historically been set at levels aimed at institutional participants, and can differ from the ₹10,000 retail minimum used for T-Bills and regular G-Secs. Confirm the current minimum with your bank or broker before transacting.
19How Retail Investors Can Access STRIPS
STRIPS have mostly traded among banks, primary dealers, insurance companies, and mutual funds — not as a walk-up retail product.
RBI Retail Direct, the platform used for T-Bills, regular G-Secs, State Development Loans, and Sovereign Gold Bonds, does not currently list STRIPS for direct purchase.
A retail investor can check with a full-service broker or bank offering bond-desk access, or look at debt mutual funds that may hold STRIPS as part of a portfolio, giving indirect exposure. Confirm current access with the platform or intermediary before assuming any of these routes work.
20Taxation of STRIPS
STRIPS are zero-coupon Government securities. Zero-coupon debt can be taxed one of two ways depending on classification: as a capital gain when sold or redeemed, or as accrued interest income taxed each year as it builds up.
Check the current rate and method that applies to your holding with a tax advisor before relying on it.
21Costs of Transacting in STRIPS
Costs depend on the route used. Institutional trades carry standard settlement and dealing costs. A retail investor going through a broker or bank bond desk should ask about brokerage, platform charges, and any fee for a stripping or reconstitution request.
22STRIPS vs Government Bonds (G-Secs)
STRIPS vs a Normal Coupon-Paying G-Sec
| Feature | Normal Coupon G-Sec | STRIP |
|---|---|---|
| Cash flows | Multiple (periodic coupon + final principal) | One single future payment |
| Periodic coupon | Yes | No |
| Principal | Paid at maturity, alongside last coupon | Represented separately by the Principal STRIP |
| Maturity dates | Usually one final maturity date | Different STRIPS from the same bond can mature on different dates |
| Reinvestment | Coupons may need to be reinvested | No interim coupon on an individual STRIP to reinvest |
| Market price behaviour | Can fluctuate with yields | Can fluctuate with yields; typically more sensitive for longer maturities |
| Typical use | General income + principal return | Targeting one specific future cash flow/date |
23STRIPS vs Other Zero-Coupon Bonds
STRIPS vs a Bond Originally Issued as Zero-Coupon
| Feature | STRIP | Bond Originally Issued as Zero-Coupon |
|---|---|---|
| Origin | Created by separating one cash flow out of an existing coupon-bearing Government Security | Structured and issued as zero-coupon from the outset |
| Underlying security | Derived from a specific original coupon-bearing bond | Not derived from another security |
| Coupon | None (by construction) | None (by design) |
| Issuer/eligibility | Government, via stripping, from notified eligible securities | Depends on whoever issued that instrument |
| Core distinction | Zero-coupon in nature, but not every zero-coupon bond is a STRIP | May share the same cash-flow shape without being created via stripping |
24STRIPS vs Treasury Bills
STRIPS vs T-Bills
| Feature | Treasury Bills (T-Bills) | STRIPS |
|---|---|---|
| Original structure | Issued directly by the government as a short-tenure, zero-coupon instrument via auction | Created by separating cash flows out of an existing coupon-bearing Government Security |
| Maximum tenure | Up to 364 days | Can extend to the residual maturity of the underlying security — potentially many years |
| Issuance route | Regular scheduled RBI auctions | Created on request via stripping, not auctioned as a fresh instrument |
| Relationship to G-Secs | A distinct, separately-issued short-tenure instrument | Directly derived from a specific underlying G-Sec |
| Retail access | Direct access via RBI Retail Direct | Limited and mostly indirect |
25STRIPS vs Fixed Deposits
STRIPS vs Bank Fixed Deposits
| Feature | STRIPS | Bank Fixed Deposit |
|---|---|---|
| Issuer | Government, via RBI's STRIPS framework | Individual bank |
| Return mechanism | Bought at a discount; single payment at maturity | Interest accrues at a stated rate; paid at maturity or periodically depending on FD type |
| Cash-flow structure | Single future payment, no interim interest | Depends on FD type; typically compounds or pays periodic interest |
| Market-price risk before maturity | Yes — price can move with yields if sold early | Not applicable in the same way; early closure involves a bank-defined penalty instead |
| Liquidity / access | Limited retail access; secondary-market sale depends on that STRIP's liquidity | Widely accessible; early withdrawal generally straightforward, subject to penalty |
| Taxation | Zero-coupon Government security tax treatment | Interest taxed at slab rate; TDS rules apply |
26Who Might Find STRIPS Useful
- Investors with a known future cash requirement on a specific date
- Investors wanting zero-coupon Government-security exposure without coupon reinvestment
- Investors comfortable evaluating secondary-market pricing and yield
Who Should Avoid STRIPS
- Investors needing regular monthly or periodic income
- An emergency fund
- Investors who do not want to evaluate bond-style pricing and yield
- Investors expecting easy, direct retail purchase
27Common Mistakes to Avoid
- Thinking a Coupon STRIP pays periodic coupons
- Assuming there is only one Coupon STRIP per underlying bond
- Confusing a Coupon STRIP with the Principal STRIP
- Confusing STRIPS with every other zero-coupon bond
- Confusing face value with market price
- Confusing coupon with yield
- Assuming all STRIPS from one bond share the same maturity date
- Assuming all STRIPS from one bond trade at identical yields
- Assuming a government security can never fall in market price before maturity
- Ignoring liquidity
- Ignoring inflation
- Assuming every broker or platform offers direct STRIPS access
- Ignoring tax treatment
- Treating stripping and reconstitution as the same process
Key Takeaways
- 1STRIPS = Separate Trading of Registered Interest and Principal of Securities — splitting one coupon-bearing Government Security into individual zero-coupon pieces.
- 2There are two types: Coupon STRIPS (one per remaining future coupon) and the Principal STRIP (one per underlying security, representing the final principal repayment).
- 3One bond can produce several Coupon STRIPS but only one Principal STRIP — together they reconstruct the bond's complete cash-flow stream.
- 4Every individual STRIP is a separate, registered Government security with its own ISIN and maturity date; Coupon STRIPS with the same maturity date can be fungible under RBI rules.
- 5STRIPS are created via stripping, not auctioned like T-Bills, and can be reversed via reconstitution.
- 6Different STRIPS from the same bond can mature on different dates and trade at different yields.
- 7STRIPS pay no interim coupon — this removes coupon reinvestment within that STRIP, but not interest-rate, liquidity, or inflation risk.
- 8STRIPS are created only from eligible, notified Government Securities — not every G-Sec can be stripped.
- 9Retail access to STRIPS is limited and mostly indirect compared to T-Bills and regular G-Secs on RBI Retail Direct.
- 10STRIPS taxation depends on classification — confirm the current treatment with a tax advisor.
