Capital Call
A general partner's formal notice requiring limited partners to fund a portion of capital they previously committed but have not yet paid in.
Definition
A capital call (also called a drawdown) is a formal notice a general partner (GP) sends to limited partners (LPs) requiring them to fund a portion of the capital they committed at subscription. Rather than wiring their entire commitment upfront, LPs in a drawdown-structured fund transfer cash only when the GP actually needs it — to fund a new investment, cover fund expenses, or true up a shortfall — and only up to the amount each LP agreed to in its limited partnership agreement (LPA).
This creates three distinct figures for every LP: committed capital (the total the LP agreed to provide over the fund's life), called capital (the portion actually drawn down and funded to date), and unfunded commitment (committed minus called — capital the GP can still call). A capital call notice states the dollar amount or percentage being called, the wire due date (commonly 5–10 business days out), and the purpose, and each call reduces the LP's unfunded commitment while increasing their funded balance in their capital account.
Capital calls are most associated with closed-end, drawdown-style vehicles — classic private equity and venture structures. Most crypto hedge funds instead run an evergreen, open-end model where investors fund their full commitment at subscription rather than being drawn down over time; capital calls show up in crypto fund contexts mainly in closed-end or fund-of-funds vehicles that call capital from their own LPs as they deploy into underlying strategies or token allocations.
Why it matters
Calling capital only when it is needed avoids the cash drag of holding large uninvested balances, which can materially improve the fund's IRR since committed dollars sit idle for a shorter period before they start earning a return. For a GP, it also means not having to manage a large standing cash balance against redemption or expense risk before it is deployed.
For LPs, the obligation cuts the other way: a commitment is a real, binding liability, not a maybe. LPs must keep enough of their committed-but-uncalled capital liquid to fund a call within the notice window, and the LPA typically specifies default remedies — interest on late funding, forced sale of the LP's interest, or forfeiture of a portion of it — for an LP that fails to meet a call.
The call mechanics
1. The GP identifies a funding need (a new position, an expense, a follow-on) and determines the aggregate dollar amount to call across the fund.
2. Each LP's call amount is calculated pro rata to its commitment: call amount = LP commitment × call percentage.
3. The GP issues a written notice to every LP stating the amount, purpose, and wire due date.
4. LPs wire funds by the due date; the GP records the call against each LP's capital account, increasing called capital and reducing unfunded commitment by the same amount.
A pro-rata call
A fund calls 25% of every LP's commitment to fund a new deal. An LP with a $2,000,000 commitment receives a call for 0.25 × $2,000,000 = $500,000.
After the LP wires the $500,000, its called capital stands at $500,000 and its unfunded commitment falls from $2,000,000 to $1,500,000 — the amount the GP can still call from that LP over the fund's remaining life.
Common mistakes
Confusing an LP's commitment with capital the fund actually holds — a commitment is a promise to fund future calls, not cash sitting in the fund; only the called and funded portion appears in the capital account.
Assuming call notice periods are standardized — they are negotiated per the LPA or a side letter and can range from a few business days to several weeks depending on the fund.
Ignoring capital-call financing: a subscription line of credit lets a GP draw on a bank facility instead of calling LPs immediately, which shortens the LP's own holding period and can inflate a fund's reported IRR relative to one that calls capital the moment it is needed.
Treating a missed capital call as a minor administrative slip — LPA default remedies for a failed call (default interest, forced transfer, partial forfeiture of the interest) are typically severe and disclosed for exactly this reason.
In practice
Most crypto hedge funds run an evergreen subscription model rather than PE-style capital calls: investors wire their full commitment at subscription and can add to or redeem from their position on scheduled dealing dates, rather than being drawn down over a multi-year investment period. Capital calls appear mainly in closed-end or fund-of-funds crypto structures — for example, a vehicle allocating sequentially into several underlying strategies or early-stage token allocations as capacity opens up.
Whichever structure a fund uses, the underlying bookkeeping discipline is the same: every dollar of called (or subscribed) capital has to tie exactly to the LP's own capital account entry, with no rounding drift between what the GP called and what the ledger records as received. That reconciliation — not the label on the cash movement — is what an LP's due diligence should actually focus on.
Questions, answered
What is a capital call?
A capital call is a formal notice from a fund's general partner requiring limited partners to fund a portion of the capital they previously committed but have not yet paid in. It states the amount or percentage being called and the wire due date.
Do crypto hedge funds use capital calls?
Not typically. Most crypto hedge funds are structured as evergreen, open-end funds where investors fund their full commitment at subscription rather than being called over time. Capital calls are more common in closed-end vehicles or fund-of-funds structures that allocate into several underlying strategies.
What is the difference between committed capital and called capital?
Committed capital is the total amount an LP has agreed to provide over the life of the fund. Called capital is the portion of that commitment the GP has actually drawn down and the LP has funded to date. The difference is the unfunded commitment still available to be called.
What happens if an LP misses a capital call?
The consequences are set out in the fund's limited partnership agreement and are typically severe — commonly default interest on the unfunded amount, forced sale of the LP's interest to another investor, or forfeiture of a portion of the interest. Funds disclose these remedies precisely because a missed call can disrupt a planned investment.
