5 Key Practices for Modern Corporate Treasury Management in 2026

Most treasury advice focuses on which instrument to pick: liquid fund versus overnight fund, FD versus corporate bond fund. That's a real decision, but it's not usually where businesses actually go wrong. Good idle cash management tends to break down at the process level: no documented policy, no review cadence, decisions concentrated with a single institution, long before it breaks down at the instrument-selection level.

Here are five practices that address that process layer specifically, rather than re-litigating instrument comparisons already covered elsewhere.

1. Formalize a written, risk-tiered investment policy

A documented policy is one of the simplest, most effective forms of risk management available to a treasury function, and it's also one of the most commonly skipped. At minimum, it should state the minimum operating buffer, the approved instruments per time horizon tier, who's authorized to approve what amount, and how often the policy itself gets reviewed. Without this in writing, decisions default to whoever's paying attention that quarter, which creates inconsistency that's hard to explain later if a board, auditor, or investor asks why a particular instrument was chosen.

2. Diversify across counterparties, not just instruments

This is a genuinely underused practice among smaller and mid-sized businesses specifically. It's not enough to split surplus across liquid, overnight, and money market funds if all of them sit with a single AMC, or if all your operating cash sits with a single bank. Concentration risk applies at the institutional level, not just the instrument level. Spreading surplus across a few well-rated fund houses and banking relationships reduces exposure to any single institution's operational or credit issues, a basic diversification principle that gets overlooked when convenience pulls everything toward one relationship.

Mutual fund investments are subject to market risk. Please read scheme-related documents carefully before investing. Past performance is not indicative of future returns.

3. Build in a regular benchmarking and review cadence

Treasury practices that made sense a year ago don't automatically stay right. AFP's annual Liquidity Survey, now in its 21st year and drawing responses from hundreds of treasury professionals, exists precisely because cash and investment policy benchmarks shift meaningfully year to year, driven by rate environments, regulatory changes, and evolving risk appetite. A business doesn't need an annual formal survey of its own to apply the same logic; a quarterly review comparing current allocation, reserve targets, and instrument mix against what the business actually needs today is usually enough to catch drift before it becomes a real gap.

4. Match liquidity to obligations, not just yield to risk tolerance

A common mistake is optimizing purely for return within a given risk tolerance, without separately checking that the liquidity profile of each instrument actually matches when the cash might be needed. An instrument can be perfectly safe and still be the wrong choice if breaking it early costs a penalty right when the business needs the funds.

5. Keep compliance and documentation current

ation, diversification, regular review, apply just as much to smaller businesses, arguably more, since they typically have less buffer to absorb a mistake.For businesses deploying surplus into AMFI-regulated instruments, staying current on scheme documentation, risk disclosures, and KYC requirements isn't optional paperwork; it's part of the discipline that keeps a treasury function defensible if questioned. This matters more as businesses grow and the amounts involved increase, since informal, undocumented practices become a real liability precisely when the stakes rise. This ties directly into the broader risk-return discipline every treasury decision should follow.

Bringing these five practices together

None of these require a large treasury team or sophisticated tooling to implement. What they require is treating cash management as a governed process rather than a series of one-off decisions, documented once, reviewed on a schedule, and diversified enough that no single instrument or institution carries outsized risk. The businesses that consistently get more value from their surplus aren't necessarily picking better instruments. They're running a more disciplined process around the same ones.

FAQs

1. What's the most commonly skipped best practice in corporate treasury management?
A documented, written investment policy. Many businesses operate with an informal, undocumented approach, which creates inconsistency and makes decisions hard to defend or explain later.

2. Why does counterparty diversification matter if the instruments themselves are already low-risk?
Because concentration risk exists at the institutional level too. Even low-risk instruments carry some exposure to the specific bank or fund house holding them, so spreading across a few reputable institutions reduces that exposure.

3. How often should a corporate treasury management strategy actually be reviewed?
Quarterly works well for most businesses, with more frequent reviews during periods of significant cash flow change or shifting interest rate conditions.

4. Is liquidity risk different from the risk of losing money on an investment?
Yes. An instrument can be very safe from a credit or market risk perspective while still being illiquid, meaning it's hard or costly to access quickly, which is a distinct risk that needs separate attention.
