Surplus deployment, counterparty limits, treasury products, board policy and impairment watch.

Section-wise decoding

1. Objective

Surplus-cash investment policy exists to protect principal and preserve liquidity first, and to optimise yield only within those constraints — a treasury investment book is not the place to reach for yield the way a dedicated investment portfolio might.

2. Applicability

Relevant for companies with bank limits, imports/exports, debt, cash surplus, multi-bank operations or treasury products.

3. Core Rules

No treasury transaction should happen without approved policy, exposure evidence, authorised counterparties, segregation of duties and independent reconciliation.

4. Practical Example

Parking surplus cash entirely in one bank's fixed deposits because it offers the highest rate concentrates counterparty risk in a single institution — a board-approved counterparty limit exists specifically to force diversification even when it means accepting a marginally lower blended yield.

5. Common Mistake

Investing short-term surplus cash in an instrument whose maturity does not match the cash's actual availability window, forcing an early exit (and often a penalty or mark-to-market loss) exactly when the cash is needed for operations.

Building a counterparty and instrument limit framework

ControlWhat it protects against
Single-counterparty exposure limit (e.g. capped as a percentage of total surplus, or an absolute rupee ceiling)Concentration risk — a single bank or issuer default should never be able to impair a large share of the company's liquid surplus
Credit-rating floor for eligible instruments and issuersChasing yield into instruments whose issuer credit quality has not been independently assessed
Instrument-type whitelist (e.g. only fixed deposits, treasury bills, and specific categories of debt mutual funds)Ad hoc use of complex or illiquid instruments that were never contemplated when the board approved the policy
Maturity-ladder limitLocking too large a share of surplus into long tenors, leaving insufficient liquidity for near-term needs

A policy that sets these limits once and never revisits them is nearly as risky as having none — counterparty ratings change, and a limit framework should be reviewed at least annually against the company's current surplus size and the treasury market's current conditions, not treated as a one-time board approval that stands indefinitely.

The instruments a corporate treasury actually uses for surplus cash

InstrumentTypical tenorWhat it trades off
Bank fixed deposits7 days to 1 year+Simple and low-risk, but concentrates counterparty exposure in whichever bank holds the deposit
Treasury bills (91/182/364-day)Up to 1 yearSovereign credit risk (effectively nil) at the cost of typically lower yield than corporate instruments
Commercial paper of other rated corporates7 days to 1 yearHigher yield than a T-bill for taking on the issuing corporate's own credit risk — exactly why a credit-rating floor matters here specifically
Liquid and overnight debt mutual fundsEffectively on-demand liquiditySame-day or next-day redemption convenience, but returns are market-linked rather than fixed, and carry the fund's own portfolio credit risk

A policy that names only "bank deposits" as an eligible instrument is not necessarily wrong, but it is a choice — one that trades away the diversification and marginally higher yield the other instruments can offer, in exchange for simplicity. Whatever the choice, it should be a deliberate, board-documented one rather than a default nobody revisited.

Marking the book — why "impairment watch" is its own discipline

Even a conservatively-managed treasury investment book needs periodic mark-to-market review, not just at year-end. A downgrade of an issuer held in the portfolio, a widening credit spread, or an early sign of stress at a counterparty bank should trigger a specific review of that holding well before any formal impairment is required under the applicable accounting standard — waiting for the accounting trigger means the treasury team is the last to know about a problem it should have caught first. A simple watch-list mechanism — flagging any holding whose issuer rating has moved, or whose market price has diverged materially from its carrying value — turns this from a year-end surprise into an ongoing, manageable process, and gives the board a genuine early-warning signal rather than a number that only moves once a year at the audit, when the room to act on it has already narrowed considerably and the options remaining are all worse than the ones available earlier.
