Bank Investment Classification: HTM, AFS and HFT Guide

How a bank classifies its securities portfolio determines its reported profits, capital and risk, which is why bank investment classification is a core treasury topic. Sound bank investment classification under the RBI framework sorts every security into Held to Maturity (HTM). Available for Sale (AFS) or Held for Trading (HFT), each with its own valuation rules. This guide explains the three categories, how they are valued, and why the distinction matters for risk management and the IIBF Treasury exam.

Why investment classification matters

Banks hold a large portion of their assets in government and corporate securities. Partly to meet the Statutory Liquidity Ratio (SLR) and partly to deploy surplus funds. The way these holdings are bucketed — the essence of bank investment classification — directly affects how gains, losses and income are recognised in the profit-and-loss account.

The classification framework. Prescribed by the Reserve Bank of India, balances two objectives: giving banks stable income from long-term holdings while ensuring that trading positions are marked to market so that risks are transparent. Misclassification can flatter earnings and hide losses. Which is why RBI lays down strict rules on what may go into each bucket and how often a security can be shifted.

For a treasury professional, mastering bank investment classification is essential to managing the bank's investment fluctuation reserve, duration risk and capital adequacy. Candidates can test these concepts on the practice mock tests at iibf.store before the exam.

The three investment categories: HTM, AFS and HFT

Under the traditional RBI framework, every investment is placed in one of three categories based on the bank's intent at acquisition. This intent-based classification drives the valuation treatment that follows.

• Held to Maturity (HTM) — securities the bank intends to hold until maturity, typically SLR government securities. They are carried at acquisition cost (with premium amortised), not marked to market.
• Available for Sale (AFS) — securities held neither for immediate trading nor strictly to maturity. They are marked to market periodically, with net depreciation provided for.
• Held for Trading (HFT) — securities acquired to profit from short-term price movements. They are marked to market at frequent intervals, with both gains and losses recognised.

Banks may shift securities between categories only at the beginning of the accounting year (or as RBI permits), and such transfers are done at the lower of cost or market value. For the latest regulatory positions, candidates should follow IIBF news and updates and the RBI rates page at iibf.store.

Valuation rules for each category

Valuation is where the three categories diverge most sharply, and getting it right is central to bank investment classification. The table below summarises the standard treatment:

A key prudential principle is conservatism: for AFS and HFT. Net depreciation (unrealised loss) in any scrip category must be provided for, while net appreciation (unrealised gain) is ignored. This prevents banks from booking paper profits. HTM securities are insulated from market swings, giving the bank stable, predictable income.

Authoritative master directions on investment classification and valuation are published by the Reserve Bank of India. Treasury aspirants can reinforce these rules through the CAIIB course at iibf.store.

Risk management and the evolving framework

Investment classification feeds directly into a bank's risk management. Marking AFS and HFT books to market exposes the bank to interest-rate risk — when yields rise. Bond prices fall and the bank must provide for depreciation. Treasurers manage this through duration analysis. Modified duration limits and the Investment Fluctuation Reserve (IFR), a buffer built from realised gains to absorb future mark-to-market losses.

It is worth noting that RBI has issued a revised framework aligning Indian bank investment classification more closely with global standards. Introducing categories such as Fair Value Through Profit and Loss (FVTPL) alongside HTM and AFS. Candidates should be aware of both the traditional HTM/AFS/HFT structure tested in most material and the direction of reform. Solid command of bank investment classification ties together accounting, valuation and risk in a way treasury examiners love to test.

SLR, the HTM ceiling and treasury strategy

Investment classification cannot be divorced from the Statutory Liquidity Ratio (SLR). Banks must hold a regulatory minimum of their net demand and time liabilities in approved securities. And the bulk of these SLR holdings naturally sit in the HTM book, where they are shielded from price volatility. RBI periodically prescribes a ceiling on the HTM portfolio as a percentage of total investments to ensure banks do not park excessive holdings in a category insulated from mark-to-market discipline.

Treasurers use this framework strategically. In a rising-rate environment. Holding more in HTM protects the profit-and-loss account from depreciation, whereas a falling-rate outlook makes the AFS and trading books attractive for booking gains. Decisions on duration, yield curve positioning and category mix are taken within the bank's board-approved investment policy and asset-liability management (ALM) framework.

This is why a complete grasp of HTM, AFS and HFT — and how each interacts with SLR, capital and the IFR — separates a competent treasury professional from a merely theoretical one. Candidates can consolidate these linkages using the match-the-concept game at iibf.store and by tracking benchmark yields on the RBI rates page.

A worked illustration ties it together. Suppose a bank buys a 10-year government bond at a premium of Rs 2 over its face value and places it in HTM. Each year it amortises a portion of that premium against income.

So by maturity the carrying value equals the face value and no sudden loss arises. Now place an identical bond in the AFS book: if market yields rise and its price falls below cost. The bank must immediately provide for that depreciation, hitting the current year's profit.

The same security. The same market, but a very different earnings impact — that single comparison captures why category choice is one of the most consequential decisions a bank treasury makes.

Conclusion: Confident command of bank investment classification across HTM, AFS and HFT links accounting, valuation and risk into one coherent treasury skill.
