Institutional Constraint Mapping: Build a Liquidity Budget
Turn institutional facts into explicit constraints: identify the obligation, amount, date, uncertainty and usable funding source. Aggregate obligations that arrive together before deciding how much illiquidity the portfolio can support.
Six-month liquidity worksheet
Put every source and obligation on the same time horizon. All amounts are hypothetical $m; the sale must be available before the payments fall due.
| Budget line | Base calls | Higher-call stress |
|---|---|---|
| Cash available | 15 | 15 |
| Sale proceeds: 5 × (1 - 20%) | 4 | 4 |
| Total usable sources | 19 | 19 |
| Spending | 7 | 7 |
| Capital calls | 8 | 10 |
| Collateral | 3 | 3 |
| Total uses | 18 | 20 |
| Sources minus uses | +1 buffer | -1 shortfall |
Original scenario, not a recommended liquidity minimum. Exclude restricted cash and avoid counting the same collateral twice.
Original worked case
A liquid portfolio can still have a funding gap
Given: Within six months an institution needs $7m spending, $8m capital calls and $3m collateral. It holds $15m cash plus public assets worth $5m that can be sold in time. Assume a 20% stressed sale haircut.
01 Total obligations
$7m + $8m + $3m = $18m.
02 Usable resources
$15m + $5m × 80% = $19m.
03 Buffer
$19m - $18m = $1m after the stressed sale.
Answer and interpretation
The plan has only $1m of remaining capacity under the stated scenario. Without the sale, it has a $3m shortfall.
$m · scale 0 to 20
| Scenario | Value |
|---|---|
| Cash | 15 |
| Cash + stressed sale | 19 |
| Base obligations | 18 |
| Higher-call obligations | 20 |
Illustrative funding scenarios. Sources and uses are compared, not added together.
Change one assumption
If capital calls rise to $10m, uses become $20m and the plan has a $1m deficit even after the stressed sale.

The key decisions, at a glance
| Concept | What to do | Watch for |
|---|---|---|
| Spending and liabilities | Place each required payment in the period it is due. | An annual average can hide a near-term peak. |
| Capital calls | Include existing commitments and adverse call timing. | Uncalled does not mean optional. |
| Usable liquidity | Apply realistic timing and stressed sale values. | A valuation is not cash available today. |
| Governance | Identify authority to sell, borrow or change commitments. | A theoretical funding source may not be approved in time. |
1. Spending and liabilities
Place each required payment in the period it is due.
Watch for: An annual average can hide a near-term peak.
2. Capital calls
Include existing commitments and adverse call timing.
Watch for: Uncalled does not mean optional.
3. Usable liquidity
Apply realistic timing and stressed sale values.
Watch for: A valuation is not cash available today.
4. Governance
Identify authority to sell, borrow or change commitments.
Watch for: A theoretical funding source may not be approved in time.
Understand the method
Part 1
Start with dated obligations rather than a preferred allocation
List spending, benefits, grants, capital calls, debt service and collateral needs by period. Record which amounts are contractual, forecast or contingent. A one-year total can hide a cash shortage in the first month if receipts arrive later. Use a time interval fine enough to capture the institution’s actual decision and payment schedule.
Then identify available sources: cash, contractual receipts, expected distributions, assets that can be sold and authorized credit facilities. Separate reliable sources from uncertain ones. An undrawn facility is useful only if it remains available under the relevant stress and can be drawn in time. Avoid counting the same security as both a planned sale and collateral supporting a borrowing capacity.
Part 2
Apply access and valuation assumptions to each source
Market value does not equal immediately spendable cash. Apply an explicit stressed sale-price assumption and consider settlement timing. For private distributions, test delay or cancellation rather than applying a cosmetic percentage reduction to an otherwise optimistic schedule. Restrictions, pledges and gates can prevent an asset from being available even if its reported value is unchanged.
Document why each assumption was selected and test a more severe alternative. A haircut is a scenario input, not an observed fact or a universal regulatory rate. Distinguish liquidity access from economic loss: a delayed $5m distribution can create a funding gap even if the asset ultimately returns the same amount. Both effects may matter, but they should not be confused.
Part 3
Map non-cash constraints into decision rules
The register should include horizon, liability sensitivity, concentration, legal restrictions, governance capacity and the institution’s tolerance for shortfall. For each constraint, state the evidence, limit or requirement, decision owner and review trigger. A vague label such as “long term” gives little guidance when a proposed fund locks capital for ten years.
Different owners produce different binding constraints. A mature pension may prioritize benefit payments and liability risk; a grant-making foundation may need a dependable spending reserve; a family office may need to reduce exposure already concentrated in an operating business. Use the owner’s actual mandate rather than assigning limits from its category name.
Part 4
Translate the binding constraint into a feasible action
After calculating a funding gap, identify the smallest set of actions that makes the plan feasible: retain cash, reduce a proposed commitment, sequence commitments, sell a specified liquid asset or obtain an authorized funding source. Show the effect on the original objective and risks. A solution that closes the first-quarter gap by creating a larger second-quarter obligation is incomplete.
The final recommendation should include a monitoring trigger. Examples are a delayed distribution, a lower liquid-asset valuation or a call rate above plan. Assign who updates the forecast and who can change commitments. A worksheet is useful only when it connects evidence to a decision before cash is needed.

More worked practice
Original teaching cases. Use the stated assumptions; these are not official exam questions or marking keys.
A quarterly funding plan fails before the annual total does
Given: An owner starts with $12m cash. Quarter 1 has $10m spending and $6m calls. A $9m distribution is expected in Quarter 2, alongside $3m spending. No other liquidity is available.
- 1Quarter 1 net cash need is $16m, creating a $4m shortfall against opening cash.
- 2Over both quarters, total uses are $19m and total sources are $21m.
- 3The positive $2m two-quarter balance does not solve the earlier $4m shortfall.
Interpretation: Timing is the binding constraint. The institution needs an accessible source or a permitted change to the first-quarter obligations before relying on the later distribution.
Check your understanding
Answer first, then open the explanation. These checks are original practice and do not generate an exam score.
1. Can a forecast distribution be treated like cash already in the bank?
No. Its timing and amount are uncertain and should be stressed according to the asset and evidence.
2. What is wrong with counting a pledged bond as fully available for sale?
The pledge may restrict access or support another funding source already counted. Reconcile legal and operational availability.
3. What should a completed constraint worksheet change?
A concrete allocation, commitment, reserve or governance decision, with a named owner and monitoring trigger.
Common questions
Should expected exits count as cash?
Only with appropriate timing and uncertainty assumptions. Show a case with delayed or absent exits instead of treating every forecast distribution as certain.
Does this calculation set the optimal alternatives weight?
No. It tests one liquidity constraint. Return objectives, liability risk, concentration and governance also affect allocation.
