Margin call (private credit fund context)

In a private credit fund context, a margin call is a demand from a lender to a fund for additional collateral or partial repayment because the value of the collateral securing a fund-level facility (typically a NAV facility or repo-based financing arrangement) has fallen below a contractually defined threshold. It is distinct from the public markets usage of the term, where margin calls relate to leveraged trading positions.

In private credit fund administration, margin calls arise on the borrowing side of the fund's balance sheet (when the fund itself is a borrower against its portfolio) rather than in the fund's lending activities to portfolio companies.

How it works

When a private credit fund borrows against its portfolio using a NAV facility, the lender typically establishes loan-to-value (LTV) thresholds: for example, a maximum of 25% LTV on a portfolio valued at EUR 200 million allows a maximum borrowing of EUR 50 million. If the portfolio NAV falls (due to write-downs, defaults in the portfolio, or revaluation events), the maximum allowable borrowing decreases.

If the outstanding facility balance exceeds the new maximum (because the collateral value has declined but the loan has not been repaid), the fund faces a "borrowing base deficiency." The credit agreement will specify the consequences: typically, the fund must either repay a portion of the facility to reduce the outstanding balance to within the permitted LTV, or pledge additional collateral to restore the borrowing base. The demand to cure this deficiency is the margin call.

For private credit funds, margin calls arising from portfolio deterioration are less frequent than in leveraged equity or repo-financed fixed income portfolios, because private credit portfolios are typically held at cost or amortised cost with periodic fair value adjustments, rather than marked to market daily. Significant deterioration must occur (usually a credit event or formal write-down at a valuation meeting) before the collateral value triggers a deficiency.

Margin calls can also arise in the context of repos or securities financing transactions in which a private credit fund has financed a portfolio of liquid credit instruments (such as CLO tranches or publicly traded loans) using short-term secured financing. In this case, the margin call mechanics are closer to those of public markets: the lender marks the collateral daily and issues a margin call if the mark declines below the haircut threshold.

The response to a margin call requires cash, either from LP capital calls, from a draw on a separate subscription facility, or from liquidating part of the portfolio. For a fund administrator, managing a margin call therefore requires: confirming the deficiency calculation with the lender, assessing the fund's available liquidity, coordinating the capital call or subscription line draw needed to fund the cure payment, and updating the fund's books to reflect the repayment.

Failure to cure a borrowing base deficiency within the contractually allowed cure period (typically five to fifteen business days) constitutes an event of default under the facility agreement, which can trigger acceleration of the full outstanding balance.

Worked example

Holborn Private Credit Fund IV holds a EUR 180 million portfolio of direct lending positions and has drawn EUR 40 million on a NAV facility, secured at a maximum LTV of 25% of the borrowing base (calculated as 85% of portfolio NAV after excluding two smaller positions that do not meet the lender's eligibility criteria).

In Q3, two portfolio companies in the fund undergo credit reviews, and the fund's valuation committee agrees to write down their carrying values by a combined EUR 30 million. The portfolio NAV falls from EUR 180 million to EUR 150 million.

Recalculating the borrowing base:

Eligible portfolio value (85% of EUR 150M): EUR 127.5 million Maximum LTV (25%): EUR 31.9 million Outstanding facility: EUR 40 million Borrowing base deficiency: EUR 8.1 million

The lender issues a margin call notice requiring the fund to cure the EUR 8.1 million deficiency within ten business days.

The fund administrator confirms the deficiency calculation is correct and coordinates a partial repayment of EUR 8.1 million, funded by drawing on the fund's subscription credit facility. The repayment reduces the outstanding NAV facility balance to EUR 31.9 million, within the permitted LTV. The borrowing base certificate is resubmitted to the lender confirming compliance.

Frequently asked questions

How is a margin call in a private credit fund different from a capital call? A capital call is a demand by the fund to its LPs to contribute equity capital they have committed but not yet funded. A margin call is a demand by the fund's lender to the fund to cure a collateral deficiency. The two can interact: a fund that receives a margin call and lacks sufficient cash to cure it may respond by issuing a capital call to LPs, using the LP proceeds to repay part of the facility. They are different transactions involving different counterparty relationships.

What triggers a margin call on a NAV facility? The primary trigger is a decline in portfolio NAV that causes the outstanding facility balance to exceed the permitted LTV calculated against the borrowing base. Other triggers may include: the loss of eligibility of a portfolio position (for example, a position that defaults and no longer meets the lender's eligibility criteria), a breach of a portfolio diversification covenant, or a missed reporting obligation (failure to deliver the quarterly borrowing base certificate within the required timeframe).

Can a private credit fund negotiate the cure period for a margin call? The cure period is defined in the credit agreement and is typically not negotiable after the event has occurred. However, funds can seek an amendment or waiver from the lender before a default is declared, particularly if the deficiency is caused by a temporary market dislocation rather than fundamental credit deterioration. Lenders have discretion to grant waivers but are not obligated to do so.

What is the difference between a margin call and an event of default under a NAV facility? A margin call is a notice from the lender identifying a borrowing base deficiency and requiring cure. It is a precursor to an event of default, not an event of default itself. If the fund cures the deficiency within the cure period, no default occurs. If the fund fails to cure within the cure period, the failure to cure becomes an event of default, which may trigger acceleration (demand for full immediate repayment of the outstanding balance) and enforcement of the facility's security.

How should a fund administrator notify LPs of a margin call? The appropriate disclosure depends on the materiality of the event and the fund's LPA provisions. A margin call that is promptly cured without material impact on the fund may not require immediate LP notification, but should be disclosed in the next quarterly LP report. A margin call that reflects serious portfolio deterioration, that cannot be cured without a capital call, or that triggers a default should prompt earlier and more detailed LP communication, potentially including an out-of-cycle report or LPAC notification.
