Liquidity and market stress

Markets need buyers and sellers willing to trade at reasonable prices, and firms need funding they can roll. In stress, both kinds of liquidity can vanish together: dealers pull back, margins rise, and investors sell what they can. This page sets out how liquidity stress develops in core markets such as government bonds and repo, how it is measured, and which central banks, regulators and boards decide.

01In brief

The short answer.

Liquidity and market stress is the drying up of the ability to trade assets and to roll funding at the same time. It develops through spirals between funding and market liquidity, limited dealer capacity and procyclical margins. Central banks, market regulators, CCP risk committees and treasurers hold the decisions.

04The question

Liquidity and market stress: how the risk develops.

Funding shortages and correlated behavior. The dossier below sets out how the risk develops, what is measured, where the data come from, how it is modelled and who decides.

Mechanism

Funding and market liquidity spiral

When funding gets harder, intermediaries cut positions, which reduces market liquidity, which raises margins and haircuts, which tightens funding further.

Mechanism

Dealer capacity is limited

Dealers' balance sheets and risk limits cap how much they can absorb. When everyone sells the same safe assets for cash, intermediation capacity runs out.

Mechanism

Procyclical margins

Margin models that respond sharply to volatility raise calls when liquidity is scarcest. Calls force sales, which raise volatility again.

Mechanism

Central banks become backstop

In core market dysfunction, central banks may buy assets or lend against them. Their facilities restore functioning and raise questions about moral hazard and exit.

05Key terms

Terms used on this page.

Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.

TermDefinition
Market liquidityThe ease of trading an asset quickly in size without moving its price.
Funding liquidityThe ability of an institution to raise cash or roll its borrowing when needed.
HaircutThe discount applied to collateral value when borrowing against it, which rises in stress.
06Indicators

What is measured, and how well.

Each indicator carries its unit, its cadence, the kind of source behind it and the evidence label a value would carry. No values are shown: a programme supplies them under its own authority.

From sources to decisions.

The topic as a computational graph: named sources feed the methods, an evidence review gates the outputs, and the decisions stay with the authorities that hold them.

10Core questions

Shared questions the industry asks.

  1. 01

    Why does liquidity disappear?

    How uncertainty, losses and risk limits cause market makers and lenders to withdraw.

  2. 02

    How do funding and market liquidity interact?

    How tighter funding forces selling and selling tightens funding.

  3. 03

    Which markets are fragile?

    Where intermediation capacity is thin relative to the size of potential flows.

  4. 04

    What role do margin and collateral play?

    How margin calls in volatile markets drain liquidity.

11Mechanisms

How the risk arises and transmits.

Liquidity spirals link funding and markets. When asset prices fall, collateral values drop and margins rise, forcing leveraged holders to sell, which lowers prices further and tightens funding again.

Correlated behaviour is the core problem. Many participants use similar risk models, limits and strategies, so they want to sell the same assets at the same time.

Intermediation capacity matters. Dealers hold inventories and make markets, but their balance sheets are finite. In large sell-offs, they may step back, widening spreads and deepening price moves.

Electronic and automated trading provides liquidity in normal times but can withdraw quickly, contributing to sudden, short-lived dislocations. Liquidity that looks deep on screens may not be there when it is most needed.

Central banks act as lenders and sometimes market makers of last resort. Expectations of intervention can stabilize markets and can also encourage risk-taking.

14Questions

Questions and answers.

What is the difference between market liquidity and funding liquidity?
Market liquidity is the ease of trading an asset without moving its price; funding liquidity is the ability to raise cash or roll borrowing. Each can drain the other in stress.
Why do margin calls amplify stress?
Because they require cash when volatility is high, which can force asset sales that raise volatility again. Predictable and transparent margin practices reduce the effect.
What is the liquidity coverage ratio?
A Basel III requirement that banks hold enough high-quality liquid assets to cover net cash outflows over a thirty-day stress period.
Does GRA predict market dislocations?
No. It researches mechanisms and scenarios, not predictions or trading signals.
Why do liquidity problems appear suddenly?
Because they depend on behaviour: once participants expect others to sell, they sell first, and liquidity evaporates quickly.
Is this investment research?
No. It is system-level research and is not investment advice.
