Investment Policy of Banks: Board Norms and Limits (IIBF TIRM 2026)

Every commercial bank in India runs its treasury on a document that rarely makes headlines but decides almost everything a dealer can and cannot do: the investment policy of banks. This board-approved charter fixes what a bank may buy, how much it may hold in any single name, who can approve a trade, and how often the whole framework gets revisited. For TIRM candidates, this is one of the highest-yield topics in Module A — questions test the approval hierarchy, the limit structure, and the review cycle, not just definitions. This article walks through the four pillars examiners expect you to know cold: board ownership, exposure limits, dealing authority, and periodic review.

📜 Why Every Bank Needs a Board-Approved Investment Policy

The investment policy of banks is not an internal treasury memo — it is a formal document that the Board of Directors must approve, because investment activity carries credit, market, and liquidity risk that ultimately sits on the bank's balance sheet. RBI's supervisory framework treats the investment policy as one of the core governance documents a bank must maintain alongside its credit policy and ALM policy, reflecting the same board-accountability principle that runs through the regulations, supervision and compliance framework for treasury operations.

A sound policy document typically covers the permitted universe of instruments (government securities, corporate bonds, money market paper, equity where permitted), the classification approach across HTM, AFS and HFT categories, benchmark portfolio composition, and the risk appetite the board is willing to carry. It also states who within the bank is accountable for policy compliance — usually the Investment Committee or ALCO, reporting upward to the board.

💡 Exam Tip: If a TIRM question asks "who approves the investment policy," the answer is always the Board of Directors — ALCO and the Investment Committee only operate within board-delegated boundaries.

Because market conditions and regulatory expectations shift, the policy is a living document. Banks are expected to place it before the board at least annually, and sooner if RBI issues fresh guidance or the bank's risk profile changes materially. This annual cadence is a recurring exam point and ties directly into the review discipline covered later in this article.

🎯 Exposure Limits and Portfolio Ceilings

The operating heart of the investment policy of banks is its system of limits. These are not arbitrary numbers — each ceiling is designed to cap a specific risk the treasury could otherwise take on unchecked. At the portfolio level, the policy fixes the maximum share of investments that can sit in HFT and AFS relative to HTM, so that a bank does not quietly convert its investment book into a trading book without board sanction.

At the counterparty level, the policy sets single-issuer and group exposure limits for corporate bonds and other non-SLR paper, usually anchored to the bank's capital funds and calibrated by credit rating. A weaker-rated issuer attracts a tighter cap than a AAA name. These concentration limits sit alongside the bank's broader credit exposure norms and are a natural companion to the corporate bond investment norms for banks that govern rating floors and issuer diversification.

The policy also carries interest-rate risk limits — duration bands and PV01 ceilings for the AFS and HFT books — and market-risk triggers such as stop-loss limits that force position unwinding once mark-to-market losses cross a defined threshold. Where the bank hedges rate risk through derivatives, the same document (or a linked treasury risk policy) references permissible hedging instruments, an area candidates should connect with interest rate futures for banks.

⚠️ Common Mistake: Candidates often assume exposure limits are set once and stay fixed. In practice, limits are reviewed and can be tightened intra-year if breaches, rating downgrades, or market stress warrant it.

🖋️ Dealing Authority and Segregation of Duties

A policy that sets limits is only effective if it also states who may commit the bank to a trade. The investment policy of banks therefore includes a dealing authority matrix: monetary limits per dealer, per desk head, and per approving authority, scaled by instrument type and tenor. A junior dealer might be authorised for small-ticket G-Sec trades, while corporate bond or derivative deals above a threshold require sign-off from the treasury head or a designated committee.

This authority structure is inseparable from the segregation of front, mid and back office functions. The dealer who executes a trade cannot also confirm or settle it — that separation is what prevents unauthorised or fictitious deals from going undetected, a control principle examined in depth under front, mid and back office operations. The policy typically cross-references deal-slip requirements, same-day confirmation with counterparties, and independent rate verification by the mid office.

Dealing authority also extends to counterparty limits — which banks, primary dealers, or brokers the treasury may transact with, and up to what settlement exposure. Breach of any dealing limit is expected to be reported immediately, not merely captured at the next periodic review, because an unreported breach compounds risk silently.

📌 Remember: Limits, authority, and segregation of duties work together — a limit without an enforcement mechanism is just a number on paper.

🔍 Policy Review, Reporting and Board Oversight

Review discipline is where many TIRM candidates lose marks, because it is easy to conflate different reporting cycles. The investment policy itself goes to the board for formal review at least once a year. Within that annual cycle, ALCO or the Investment Committee reviews portfolio performance, limit utilisation, and exception reports far more frequently — typically monthly or even more often during volatile markets — and escalates material deviations to the board ahead of the scheduled annual review.

Reporting under the policy usually covers portfolio composition against approved ceilings, mark-to-market movements, instances of limit breach with corrective action taken, and the status of non-performing investments, since provisioning treatment for impaired holdings is itself governed by rules the policy must stay consistent with — see provisioning norms for non-performing investments for the downstream accounting impact.

Because the investment book interacts directly with the bank's cash and liquidity position, effective oversight also draws on the same governance discipline used for treasury liquidity management, ensuring investment decisions never compromise statutory reserve maintenance or daily cash needs. Internal audit and the risk management department independently verify that actual dealing activity stayed within the policy at all times, and their findings feed back into the next annual revision.

Ultimately, the review cycle closes the loop: board sets the policy, ALCO operates within it, audit checks compliance, and the board revisits the policy armed with that feedback. Candidates preparing for the risk analysis and control chapter should map this cycle alongside VaR and stress-testing review frequencies, since examiners often test them together.

🏁 Conclusion: Lock In the Investment Policy Framework

The investment policy of banks ties together governance, limits, authority, and review into one accountable cycle — and TIRM questions reward candidates who can place each control at the right level: board, ALCO, dealer, or auditor. Revisit the RBI framework on rbi.org.in for the current supervisory expectations on investment governance, then reinforce the concept with timed practice.
