Funding liquidity risk

Funding liquidity risk is the risk of being unable to meet expected and unexpected cash-flow and collateral needs efficiently without harming daily operations or financial condition.

On this page

In plain terms — Owning valuable assets does not mean that cash is available when margin, settlement, redemptions, or other obligations fall due. Selling quickly or financing collateral can become costly or impossible during stress.

The BCBS describes liquidity as the ability to fund increases in assets and meet obligations as they come due without unacceptable losses. It defines funding liquidity risk as the risk that a firm will be unable to meet expected and unexpected cash-flow and collateral needs efficiently without affecting daily operations or financial condition. The principles are written for banks; the distinction is also useful for intermediaries, funds, and traders that depend on margin, financing, or timely transfers. Specific regulatory duties depend on the entity and jurisdiction.

It is not the same as the funding rate on a perpetual swap. That payment is a contractual cost of the instrument; funding liquidity concerns the ability to obtain and mobilise resources when a payment is required.

Funding liquidity concerns timely payments and resources; market liquidity concerns trading time and cost.

Sources of funding need

Driver Control question
Margin and collateral how much cash or eligible collateral could be required if volatility and haircuts rise?
Maturities and settlement which flows are due by currency, entity, and time bucket?
Withdrawals or redemptions which demands may become concentrated in the same period?
Maturing funding which sources must be renewed and which may be unavailable?
Operational dependencies how long does it take to move cash or collateral across banks, brokers, custodians, and CCPs?
Contingent commitments which guarantees, facilities, or off-balance-sheet positions can become actual needs?

An aggregate balance can conceal a shortage in the currency, entity, or account where payment must occur. Even a formally available facility may be conditional, revocable, or too slow for the operational deadline.

Measurement and stress

A funding map separates contractual and contingent inflows and outflows by time, currency, entity, and custody location. Where relevant, scenarios should combine:

  • loss or reduction of a funding source;
  • higher margin calls and haircuts;
  • lower collateral value or eligibility;
  • settlement delays and transfer constraints;
  • withdrawals, redemptions, or commitment drawdowns;
  • reduced market liquidity and sales at unfavourable prices;
  • disruption at an intermediary, custodian, bank, or technology provider.

Useful outputs are not limited to an ending balance. They show when a shortfall occurs, which entity is affected, which resources can actually be mobilised, how long that takes, and which assumptions fail.

Contingency funding plan

BCBS Principle 11 requires banks to maintain a formal contingency funding plan. As a control framework, a credible plan specifies:

  1. indicators, triggers, and authority for activation and escalation;
  2. decision-making roles and communication channels;
  3. funding sources ordered by reliability, amount, currency, and mobilisation time;
  4. collateral that is available, unencumbered, and transferable;
  5. permitted actions and their costs, legal constraints, and operational consequences;
  6. coordination with brokers, banks, custodians, counterparties, and infrastructures;
  7. exercises, updates, and a record of deficiencies found.

The plan should not add together incompatible resources or assume that every market, funder, and transfer remains available in the same shock. Operational testing checks access, documents, timing, and collateral rather than merely confirming that a contact list exists.

Interaction with market liquidity

Market liquidity concerns trading an asset; funding liquidity concerns paying obligations. A margin increase may force asset sales, while a less liquid market can reduce collateral value and generate further calls. The ECB analyses these feedback loops between market and funding liquidity and the channels through which they can amplify stress.

Typical mistake — Counting the face value of assets and facilities as cash immediately available without allowing for haircuts, transfer times, contractual restrictions, and simultaneous use under stress.
