Treasury Organisation Structure: Front, Mid & Back Office (2026)

Every bank treasury that deals in government securities, foreign exchange and derivatives is built on the same skeleton: the classic Treasury Organisation Structure that separates the people who take risk from the people who measure it and the people who settle it. For IIBF's Treasury Management paper, this is one of the most reliably examined areas, because it is conceptual, stable and easy to frame questions on. If you understand why the front office, mid office and back office must never report to the same person, you can answer most questions in this module without memorising a single number.

This guide walks through the three-office model, the reporting lines RBI expects, the daily workflow of a deal from quote to settlement, and the control failures that examiners love to test. Pair it with the chapter on Scope and Function of Treasury Management for full coverage.

🏛️ Why the Three-Office Model Exists

A treasury is unusual within a bank: a single dealer can commit the balance sheet to crores of rupees in seconds, over a telephone or an electronic platform, with no documentation at the moment of commitment. That speed is the whole point of a dealing room — but it also means the traditional maker-checker controls used in branch banking simply cannot operate in real time.

The answer that global banking regulators converged on after a series of rogue-trading losses in the 1980s and 1990s is functional segregation. Deal origination, deal risk measurement and deal settlement are placed in three separate offices, each with its own staff, its own systems access and — crucially — its own reporting line to the top of the organisation. No single officer can originate a trade, value it favourably and then confirm it with the counterparty.

This is not merely good practice. RBI's internal control expectations for treasury operations require that the back office be functionally and administratively independent of the dealing room, and that risk measurement not be performed by risk takers. The integrated treasury model, where domestic money market and forex desks sit on one floor under one head, actually intensifies this need: more products under one roof means more scope for one desk to hide a loss inside another.

💡 Exam Tip: The single most repeated point in this module is that the back office must NOT report to the treasurer or the head of the dealing room. It reports to Operations or to the CFO. If an option says "back office reports to Head — Treasury", it is wrong.

💹 Front Office: Where the Risk Is Taken

The front office is the dealing room. It houses dealers and traders organised by product — money market, forex, fixed income, derivatives — usually under a Chief Dealer, who in turn reports to the Head of Treasury. Its mandate is to run the bank's positions within approved limits and to earn income from three broad sources.

The first is customer or merchant business: quoting a corporate a rate for a dollar remittance, covering that exposure in the interbank market, and keeping the spread. This is low-risk, annuity-like income and is the reason most banks run a treasury at all. The second is balance sheet management: maintaining CRR and SLR, deploying surplus liquidity in call money or TREPS, and funding shortfalls. The third is proprietary trading — taking deliberate positions on interest rates or currency movements. Proprietary income is the most glamorous and the most tightly limited.

Front office staff work to a limit framework handed down by ALCO: intraday and overnight open position limits, stop-loss limits, gap limits, counterparty limits and, for derivatives, notional and sensitivity limits. Dealers may not amend their own limits, and every deal is recorded on tape or on the electronic platform's audit trail at the point of execution. Deal slips — physical or system-generated — flow immediately to the back office and never sit with the dealer overnight.

Because dealers cannot self-police, banks also enforce mandatory block leave, typically a continuous fortnight, so that any concealed position surfaces while the dealer is away from the desk. Study the limit architecture in detail in our guide to treasury risk limits and controls.

🛡️ Mid Office: Independent Risk Measurement

The mid office is the youngest of the three functions and the one candidates understand least. Its job is not to process deals and not to take positions — it is to measure, monitor and report risk independently of the people creating it.

A typical mid office does four things every day. It marks the trading book to market using rates sourced independently — from FBIL benchmarks, CCIL trade data or an agreed external feed — never from the dealers' own quotes. It computes risk metrics: value at risk, PV01, duration, and stress-test outcomes on the portfolio. It monitors every limit set by ALCO and flags breaches and excesses to management the same day, with a documented ratification trail. And it prepares the risk reports that go to ALCO, the Risk Management Committee and the Board.

The mid office also validates the pricing models used for structured and derivative products, checks that deals were struck within the day's market range, and investigates off-market rates — a classic device for shifting profit to a favoured counterparty. It reports to the Chief Risk Officer or the Risk Management Department, never to Treasury. The valuation and duration mathematics it applies is covered in Fixed Income Securities, Duration and Convexity, and the portfolio-level techniques appear in our companion piece on value at risk in treasury portfolios.

⚠️ Common Mistake: Students routinely place mark-to-market valuation in the back office. Independent revaluation and risk reporting sit with the MID office; the back office handles confirmation, settlement, reconciliation and accounting entries.

⚙️ Back Office: Confirmation, Settlement and Reconciliation

The back office turns a verbal or electronic commitment into a completed, accounted transaction. Its work begins the moment a deal slip arrives and runs through to reconciliation days later.

First comes verification: checking the deal slip against the dealing platform record and against the counterparty's independent confirmation, matching rate, amount, value date and settlement instructions. Unconfirmed deals are escalated, not settled. Next is settlement — issuing payment instructions through RTGS, NEFT, SWIFT or the CCIL guaranteed settlement route for government securities and forex, and ensuring securities move through SGL or CSGL accounts. Then comes accounting: passing entries, applying income recognition and provisioning norms to the investment portfolio, and maintaining statutory registers.

Reconciliation is the back office's most under-rated duty. Nostro account balances must be reconciled continuously so that unreconciled entries — the classic hiding place for a suppressed loss — are aged and cleared. Suspense and mirror accounts get the same treatment. The back office also files regulatory returns and provides data for RBI reporting.

Confirmations must be exchanged independently of dealers, and settlement instructions must come from a static database that only the back office can amend. Where a bank runs currency positions, this discipline interlocks with everything discussed in foreign exchange risk management.

🚨 Control Failures Examiners Test

Almost every treasury scandal in banking history reduces to a breakdown in one of the separations described above, which is why examiners frame situational questions around them.

The commonest failure is a dealer retaining settlement or confirmation access. Once the person who strikes a trade can also confirm it, a fictitious deal becomes indistinguishable from a real one. A second is off-market rate dealing — booking a trade well away from the prevailing market to transfer value to a counterparty or to shift a loss into a future period. Independent rate-range checking by the mid office is the designed defence.

A third is chronic non-reconciliation of nostro accounts, which allows an unauthorised payment to sit unnoticed for months. A fourth is limit excesses that are ratified after the event as a routine, converting a hard control into a formality. A fifth is failure to enforce mandatory leave, and a sixth is dealing from mobile phones or outside the recorded dealing room, which destroys the audit trail. The RBI's master directions on investment and derivative exposures — available on the regulator's own site at rbi.org.in — set out the governance expectations banks are examined against.

📌 Remember: Segregation is about reporting lines, not seating. Two teams on the same floor are still segregated if they report to different functional heads; two teams in different cities are not segregated if both report to the treasurer.
