Portfolio & liquidity
Portfolio liquidity lenses for partially illiquid books
Illiquidity is not binary; neither is liquidity risk. Desks that win use explicit ladders—days to weeks to months to strategic exits—paired with observable marks, haircuts, and leverage everyone replays. When immediacy is assumed but unobtainable, stress tests lie politely and ICs approve fantasies. Make horizon, depth, and participation constraints first-class parameters so PM and risk argue in dollars at a date, not metaphors.
Why ‘liquid enough’ collapses
Enough for whom, at what size, under what market? Unqualified liquidity claims are marketing for internal use.
Liquidity is path-dependent: exit on your schedule differs from exit when everyone else is also exiting.
Ladder design
Bins for days, weeks, months, locked; attach min/max participation and counterparty assumptions.
Document what ‘participation’ means—ADV%, block limits, negotiated cross—precision prevents false agreement.
Marks and staleness
Show last mark source and age; escalate when age exceeds policy—automatically if possible.
Separate “price unavailable” from “price unchanged”—silence is not innocence in illiquid books.
Scenario coupling
Shock spreads, depth withdrawal, and margin step-ups together—single-factor liquidity stress misleads.
For private sleeve + hedge overlay books, state basis and roll liquidity explicitly.
Communication with investors
External language should mirror internal ladders or you invite credibility gaps after first redemption wave.
Pre-write redemption-stress FAQs with counsel; improvising under inbound calls breeds overconfidence or panic.
Data you need from counterparties
Lockup calendars, gates, NAV frequency, side-pocket rules—push for machine-readable updates, not PDF surprises.
If a manager cannot supply timely liquidity notices, model conservatively and say so in risk memos.
Tooling patterns
Deterministic liquidity haircut curves in calculators; link outputs to book context, not floating numbers.
Outputs should carry ladder bucket + shock id—PNG exports without that pair are incomplete risk objects.
Anti-patterns
Assuming exchange liquidity for blocks; ignoring cross-margin effects; treating advisor marks as sacrosanct without challenge.
Silent doubling of exposure via synthetic leverage while liquidity ladder only reflects cash sleeve.
