Lender of Last Resort
Lender of Last Resort
The central-bank role of supplying emergency liquidity to eligible financial institutions when ordinary funding markets are unable or unwilling to provide it.
Lender of last resort is the role of providing emergency liquidity during periods of financial stress.
Liquidity Support Is Not the Same as Solvency Support
A lender-of-last-resort facility is designed primarily to address liquidity problems: institutions may own assets but be unable to obtain usable funds quickly enough to meet obligations.
If an institution is fundamentally insolvent, lending can postpone but does not by itself eliminate the underlying loss.
What Is a Lender of Last Resort?
During financial stress, normally liquid markets can freeze and institutions can lose access to funding. A central bank may respond by lending against eligible collateral or through emergency facilities.
The objective is generally to prevent a temporary funding shortage from cascading through payment systems and otherwise solvent institutions.
Why the Function Exists
Banking combines liquid liabilities with assets that can be longer-term or difficult to sell immediately. That maturity and liquidity mismatch can create vulnerability during runs or market disruptions.
Liquidity vs. Solvency
The distinction is central to understanding emergency lending.
The institution lacks immediately usable funds but may still have sufficient asset value overall.
The institution's asset value may be insufficient relative to its liabilities even if temporary funding is available.
A Simplified Crisis Sequence
Emergency support can interrupt a liquidity spiral.
Why It Matters for Monetary Literacy
The lender-of-last-resort function helps explain why central banks matter during crises even when they are not replacing commercial banks. It also shows why liquidity, collateral, solvency, and moral hazard must be analyzed separately.
A lender of last resort can bridge a liquidity shortage, but it cannot make bad assets valuable merely by lending against them.
