Cash management

Cash management is the discipline of knowing what cash you have, what it is committed to, and how quickly you can reach it. Yield is the last question, not the first.

Key takeaways
  • Liquidity and safety come before yield in every sensible treasury policy.
  • Splitting cash into operating, near-term and strategic tiers makes decisions obvious.
  • Runway is a function of committed spend, not just historical burn.
  • Concentration risk is a real consideration for companies holding meaningful balances.
  • Treasury decisions should be written down and approved, not improvised.

What cash management is for

For an operating company, cash management has one job: make sure money is available when it is needed, without taking risks that are not being consciously priced. Everything else — yield, sweep arrangements, laddering — is optimisation on top of that.

Companies get into trouble when the sequence inverts and yield drives the structure. The failure mode is not usually loss of principal; it is having cash in a place that cannot be reached on the day payroll runs.

Three liquidity tiers

Tiering removes most of the debate from treasury decisions. Once each tier has a purpose and a target size, the question of where a new inflow should sit answers itself.

  • Operating — one to three months of outflows, immediately accessible, no yield expectation.
  • Near-term — three to twelve months of planned spend, accessible within days.
  • Strategic — cash with no planned use inside a year, where duration can be considered.

Runway, properly calculated

Runway is usually quoted as cash divided by last month's burn. That is a serviceable estimate and a poor planning tool, because it ignores commitments already made and hiring already agreed.

A defensible calculation starts from committed outflows: signed contracts, agreed headcount, scheduled payables and known seasonal costs. It is normally a shorter and much more useful number.

  1. Start with contracted commitments rather than historic averages.
  2. Include hiring that has been agreed but not yet started.
  3. Include annual costs that fall in a single month, such as insurance renewals.
  4. Model at least one scenario where revenue underperforms plan.

What a short treasury policy should state

One page is usually enough for companies below a few hundred employees.

ElementWhat it should say
ObjectivePriority order: liquidity, safety of principal, then yield
Tier targetsTarget balance for each liquidity tier and the trigger to rebalance
Permitted instrumentsWhat cash may be held in, and explicitly what it may not
Counterparty limitsMaximum exposure to any single institution
AuthorityWho may move money, above what amount, with whose approval
ReviewHow often the policy is reviewed and by whom

Concentration and counterparty risk

Holding an entire operating balance at a single institution is a decision, whether or not it was made deliberately. Events in recent years have made boards considerably more interested in the answer.

Mitigations are straightforward: a second banking relationship established before it is needed, deposit programmes that spread balances across institutions, and a written counterparty limit that triggers action automatically.

See FDIC deposit insurance resources for how coverage limits apply in the United States.

Frequently asked questions

Enough to cover near-term outflows comfortably, commonly one to three months, with the balance held in tiers that are still accessible quickly. The right figure depends on the volatility of your inflows.

Only after liquidity and safety are settled, and only with cash that has no planned use. For most early-stage companies the amounts involved are small relative to the operational risk of getting it wrong.

It changes timing. Card balances settle on a fixed cycle, so that outflow is predictable and should be modelled explicitly rather than treated as general operating spend.

Whoever your policy names — commonly the CFO or finance lead within limits, with board approval above a threshold. The point is that the authority is written down before it is needed.

Understand the business finance picture, not just the card

Cards are one component. Accounts, payables, controls and reporting decide whether a finance stack actually holds together at scale.
