HTM AFS HFT Classification: Bank Investment Portfolio Guide

The bank investment portfolio HTM AFS HFT classification framework decides where every rupee a bank invests must sit, how that security is valued, and when gains or losses hit the profit and loss account. For anyone preparing the IIBF Treasury, Investment and Risk Management (TIRM) paper, this is one of the highest-yield topics in the entire syllabus, because it links accounting treatment, capital adequacy and interest-rate risk into a single chain of reasoning. Master it once and a whole cluster of exam questions falls into place.

This guide walks you through the legacy RBI categories, the 2023 revised classification framework that took effect from 1 April 2024, the mechanics of G-Sec auctions, bond valuation and duration, and how the Statutory Liquidity Ratio ties it all together. The treatment is exam-ready, conceptual where it needs to be and practical where it pays off in marks. Always confirm any specific effective date or threshold against the official RBI master direction, since regulatory wording is periodically refreshed.

RBI Investment Classification: HTM, AFS and HFT Explained

Under the older RBI master direction, every security a bank acquired had to be slotted into one of three categories at the point of purchase. The choice was not cosmetic; it dictated valuation, provisioning and how freely the bank could later trade the scrip.

Held to Maturity (HTM) covered securities the bank intended to hold until redemption. These were carried at acquisition cost, with any premium amortised over the residual life, rather than marked to market. Because they were not revalued, day-to-day price swings did not disturb the books, which made HTM the natural home for long-dated government securities held for steady income.

Available for Sale (AFS) was the flexible middle bucket for securities that were neither pure trading positions nor strict hold-to-maturity assets. AFS holdings were marked to market periodically, so their carrying value moved with prevailing prices. Held for Trading (HFT) captured securities bought to profit from short-term price movements, typically intended for sale within ninety days, and was valued at market with frequent revaluation.

The key exam distinction is valuation treatment. HTM securities escaped mark-to-market; AFS and HFT did not. Net depreciation in the AFS and HFT books had to be provided for, while net appreciation was ignored, reflecting the conservative principle of prudence. Banks also faced shifting rules and ceilings that limited how freely scrips could move between buckets.

• HTM — intent to hold to maturity, carried at amortised cost, no mark-to-market.
• AFS — neither pure trading nor hold-to-maturity, marked to market periodically.
• HFT — short-term trading book, valued at market with frequent revaluation.

If you want a deeper drill on these three buckets in isolation, our companion explainer on Bank Investment Classification: HTM, AFS and HFT for TIRM walks through worked examples and provisioning entries.

The 2023 Revised Classification Framework: HTM, AFS and FVTPL

Effective from 1 April 2024, the RBI overhauled the investment classification regime to align Indian banks with global accounting standards, broadly mirroring IFRS 9 and Ind AS 109. The reform matters for the TIRM paper because candidates appearing in 2026 are expected to know both the legacy terminology and the revised structure, and to explain how one maps onto the other.

The new framework replaces the old buckets with three principle-based categories driven by a business-model assessment and the cash-flow characteristics of the instrument. The three categories are Held to Maturity (HTM), Available for Sale (AFS) and Fair Value through Profit and Loss (FVTPL), with Held for Trading now treated as a sub-category within FVTPL rather than a stand-alone bucket.

A crucial change is that HTM securities are now subject to the Solely Payments of Principal and Interest (SPPI) test: only instruments whose contractual cash flows are purely principal and interest can qualify, and they must be held under a business model that collects those cash flows. The old ninety-day cap on HFT and the percentage ceiling on the HTM portfolio have been removed. For AFS, fair-value gains and losses now flow through a dedicated AFS reserve in equity (other comprehensive income) rather than straight to the profit and loss account.

• HTM — debt instruments held to collect contractual cash flows; must pass the SPPI test.
• AFS — fair valued, with changes routed to an AFS reserve in other comprehensive income.
• FVTPL — fair valued, with all changes taken directly to profit and loss; the trading book sits here.

G-Sec Auctions and the Role of Primary Dealers

Government securities are the backbone of a bank treasury, so the TIRM paper expects familiarity with how they reach the market. The RBI conducts G-Sec auctions on behalf of the central and state governments through its e-Kuber platform. Auctions run on either a uniform price basis, where all successful bidders pay the single cut-off price, or a multiple price basis, where each successful bidder pays the exact price it bid. Treasury Bills and dated securities are issued under a published, typically half-yearly, issuance calendar.

Primary Dealers (PDs) are RBI-registered entities that underwrite and make markets in government securities. They are obliged to bid in every primary auction, achieve a minimum success ratio, and provide two-way quotes in the secondary market, which keeps the G-Sec market deep and liquid. Banks watch the policy repo rate and the broader rate environment closely, since these drive auction yields and, in turn, the valuation of the AFS and FVTPL books.

Understanding auction design also helps you reason about price discovery: a uniform-price auction reduces the so-called winner's curse for bidders, while a multiple-price auction can extract more revenue for the issuer. Either way, the cut-off yield that emerges feeds directly into how outstanding bonds are repriced across the market.

Bond Valuation, Yield and Duration

Bond pricing becomes straightforward once you internalise the inverse relationship between price and yield. A bond is simply the present value of its future coupon payments plus its redemption value, discounted at the prevailing market yield. When market yields rise, that present value falls and the bond price drops; when yields fall, prices climb. The Yield to Maturity (YTM) is the single discount rate that equates the price to all future cash flows, and it is the standard benchmark for comparing securities of different coupons and maturities.

Duration measures how sensitive a bond price is to a change in yield. Macaulay duration is the weighted average time to receive the cash flows, while modified duration estimates the percentage price change for a one percent move in yield. A higher duration means greater interest-rate risk, which matters directly for the AFS and FVTPL books where mark-to-market (MTM) revaluation is mandatory. Treasury desks also track PV01, the price change for a one-basis-point shift in yield, to size and hedge their exposure.

Worked Intuition: Why Duration Drives MTM

Suppose yields rise sharply. A bond with a high modified duration falls in price far more than a short-duration bill. If that bond sits in the AFS or FVTPL book, the loss must be recognised, denting either the AFS reserve or the profit and loss account. If the same bond sits in HTM and passes the SPPI test, it stays at amortised cost and the unrealised loss never surfaces. That single contrast explains why the choice of bucket is a risk-management decision, not just an accounting label.

Numerical questions on yield and duration are among the most reliable mark-scorers in the paper, so they reward repeated practice. Build that fluency with our explainers on Bond Duration explained for CAIIB TIRM and Bond Valuation in Bank Treasury, then test yourself on the dedicated treasury sets in the TIRM mock test bank.

SLR Investments and the Statutory Liquidity Ratio

The Statutory Liquidity Ratio (SLR) requires every bank to maintain a minimum percentage of its Net Demand and Time Liabilities (NDTL) in approved liquid assets, predominantly government securities, cash and gold. SLR investments therefore form the largest slice of most bank portfolios and historically dominated the HTM bucket, where their stable amortised-cost valuation suited a long-term liquidity buffer.

SLR is both a prudential and a monetary-policy tool: it ensures banks can meet liabilities while channelling a steady flow of funds into government borrowing. For exam purposes, remember that SLR is computed on NDTL, that eligible securities are notified by the RBI, and that breaches attract penal interest. Banks must report SLR maintenance to the RBI and hold the bulk of these securities consistently with the revised classification rules, which is exactly where classification, valuation and liquidity converge.

A Practical Study Plan for This Topic

Treat this chapter as a layered build rather than a single read. The following sequence works well in the final weeks before the exam.

1. Lock the definitions first. Write out HTM, AFS, HFT and FVTPL in your own words, then map each legacy bucket to its revised counterpart.
2. Trace one security end to end. Take a hypothetical 10-year G-Sec and follow it from auction, through classification, valuation and MTM, to SLR eligibility.
3. Drill the numbers. Practise YTM, Macaulay and modified duration, and PV01 calculations until the formulas feel automatic.
4. Reinforce vocabulary actively. Use the match-the-terms game to cement definitions under time pressure.
5. Simulate the paper. Sit full-length sets from the IIBF mock tests and review every wrong answer against the concept above.

Common Mistakes to Avoid

• Confusing intent with the new test. Under the revised framework, HTM is gated by the SPPI test and business model, not merely by a stated intent to hold.
• Marking the HTM book to market. HTM stays at amortised cost; only AFS and FVTPL are revalued.
• Forgetting where AFS gains go. Post-reform, AFS fair-value changes flow to an AFS reserve in equity, not directly to the profit and loss account.
• Mixing up Macaulay and modified duration. Macaulay is a time measure; modified duration is the price-sensitivity measure used for risk.
• Treating SLR as a percentage of total assets. SLR is computed on NDTL and met with RBI-notified eligible securities.
• Quoting outdated caps. The old ninety-day HFT cap and the HTM ceiling were removed; always cross-check the current master direction.

Frequently Asked Questions

What is the difference between HTM, AFS and HFT?

HTM holds securities to maturity at amortised cost without mark-to-market, AFS is a flexible category that is periodically marked to market, and HFT is a short-term trading book valued at market with frequent revaluation. Under the 2023 revised framework, HFT becomes a sub-category of Fair Value through Profit and Loss. The valuation treatment is the distinction examiners test most often.

What changed in the 2023 revised investment framework?

Effective 1 April 2024, the RBI introduced principle-based categories aligned with IFRS 9 and Ind AS 109. The three categories are HTM, AFS and FVTPL, HTM is now subject to the SPPI test, and AFS fair-value changes flow to an AFS reserve in equity. The old ninety-day HFT cap and the HTM percentage ceiling were removed.

How are G-Sec auctions conducted and what is a Primary Dealer?

The RBI auctions government securities on the e-Kuber platform using either a uniform-price or a multiple-price method. Primary Dealers are RBI-registered entities that must bid in every auction, meet a minimum success ratio, and provide two-way quotes in the secondary market. Their obligations keep the G-Sec market liquid and support orderly price discovery.

How does duration affect bond price and mark-to-market?

Duration measures price sensitivity to yield changes, and modified duration estimates the percentage price move for a one percent change in yield. A higher duration means higher interest-rate risk, which directly affects mark-to-market losses or gains in the AFS and FVTPL books when yields move. Securities in HTM are insulated because they remain at amortised cost.

Why is SLR usually held in the HTM bucket?

SLR investments are a long-term liquidity buffer computed on NDTL, so banks have traditionally parked them in HTM where amortised-cost valuation avoids mark-to-market volatility. This keeps the statutory cushion stable even when market yields swing. Under the revised rules, banks still hold the bulk of SLR securities consistently with the classification framework.

Do I need to know both the old and the new framework for the TIRM exam?

Yes. Candidates appearing in 2026 should know the legacy HTM/AFS/HFT terminology and the revised HTM/AFS/FVTPL structure, and be able to map one onto the other. Questions frequently test the differences, the SPPI test and the removal of the old caps. Always confirm current thresholds against the latest released IIBF and RBI material before the exam.

Conclusion

Get the bank investment portfolio HTM AFS HFT classification framework right and the rest of the TIRM treasury syllabus starts to feel coherent: the 2023 revised categories, G-Sec auctions, bond valuation, duration and SLR all hang off the same logic of how a security is held, valued and risked. Pair this conceptual clarity with steady numerical practice and you will handle both theory and calculation questions with confidence on exam day. For the official rules and any updates, the Indian Institute of Banking and Finance remains the primary source to verify before you appear.
