Capital Allocation Constraints

Capital Allocation Constraints are the structural limits that govern how much capital an allocator can deploy, to whom, and when. These constraints can be policy-based (IPS limits), portfolio-based (risk budget, concentration), operational (pacing capacity), or practical (liquidity, denominator effects). They often explain why a good manager still gets a no: the slot is full or the constraints are binding.

From an allocator perspective, constraints protect the portfolio. From a GP perspective, constraints explain “why now is hard” and what it would take to become actionable later.

How allocators define constraint risk drivers

Allocators evaluate constraints through:

• Target ranges and drift bands: what exposure can be added now
• Pacing and vintage limits: annual commitment budget and vintage risk rules
• Liquidity requirements: cash buffers and funding timelines
• Concentration controls: per manager, strategy, geography, theme
• Risk budgets: factor exposure and drawdown tolerance
• Governance limits: board/trustee approvals, ticket thresholds
• Rebalancing rules: when adds are prohibited until drift is corrected

Allocator framing:
“Is this a ‘no’ on the manager—or a ‘no’ on capacity right now?”

Where constraints matter most

• high illiquid exposure portfolios
• drawdowns where denominator effects bind
• periods of distribution drought
• institutions with strict governance escalation thresholds

How constraints change outcomes

Strong constraint discipline:

• prevents over-commitment in bull markets
• reduces forced selling and liquidity stress
• increases predictability and governance defensibility
• supports long-term program stability

Weak constraint discipline:

• causes reactive freezes and manager churn
• increases regret from buying high and cutting in stress
• creates inconsistent approvals and exceptions
• damages internal trust in portfolio governance

How allocators evaluate discipline

Confidence increases when:

• constraints are quantified and communicated
• the allocator can explain what would change capacity (timing, distributions, rebalancing)
• exceptions are documented and rare
• constraints are linked to risk budgeting and pacing models

What slows decision-making

• constraints discovered late in diligence
• unclear capacity planning
• inconsistent exception logic
• inability to quantify available commitment budget

Common misconceptions

• “If they like us, they’ll invest” → constraints often override preference.
• “Constraints are excuses” → constraints are governance survival tools.
• “More meetings will change it” → only capacity changes it.

Key questions during diligence

• What are your current binding constraints (pacing, liquidity, concentration)?
• How much commitment capacity exists this year in this strategy?
• What would need to change for capacity to open?
• What is your rebalancing posture after recent market moves?
• How do you handle denominator effect pressures?
