Lender of Last Resort
What is Lender of Last Resort?
A lender of last resort is a central bank that supplies emergency liquidity to solvent banks during a panic to stop bank runs from spreading.
When a bank cannot borrow in normal markets during a crisis, the central bank (the Fed, via the discount window) lends to it to prevent a liquidity shortage from triggering broader failures. The goal is financial stability, halting contagion, not bailing out insolvent firms. This function complements deposit insurance in preventing bank panics.
Lender of Last Resort: a worked example
Meridian Bank holds $100 million of cash and $900 million of performing 10-year loans against $950 million of deposits, so it is solvent with $50 million of equity. A rumor sends depositors to demand $300 million within two days. Cash covers $100 million. Raising the other $200 million by dumping loans that panicked buyers will pay only 70 cents on the dollar for means selling $200 million / 0.70 = $286 million of face value and booking an $86 million loss, which more than wipes out the $50 million of equity and turns a solvent bank into an insolvent one. A central bank loan of $200 million against those loans as collateral pays the depositors and leaves the bank standing.
The mistake students make with lender of last resort
The wrong reading is that a lender of last resort rescues failing banks. The classic doctrine is narrower: lend freely, against good collateral, at a penalty rate, and only to banks that are solvent but short of cash. An institution whose assets are genuinely worth less than its deposits gets resolved or wound down, not lent to. The confusion is natural because both cases involve public money arriving at a bank in crisis, but the collateral test is what separates them.
Lender of Last Resort questions
What does lender of last resort mean?
Lender of last resort describes a central bank standing ready to lend to banks that cannot borrow anywhere else during a panic. Ordinary funding markets freeze just when a bank most needs cash, so the central bank supplies short-term loans secured by the bank's own assets. The aim is to stop one bank's cash shortage from spreading into a run on institutions that are perfectly healthy.
Is lender of last resort support the same as a bailout?
Lender of last resort support is a collateralized loan, while a bailout injects capital into a firm that has already lost it. The emergency lender expects repayment with interest and holds assets as security, so the public is protected unless the collateral itself fails. A bailout accepts losses to keep an insolvent firm alive. Treating the two as identical makes every liquidity operation look like a rescue.
Why does a central bank charge a penalty rate?
A central bank charges a penalty rate so emergency borrowing stays unattractive in normal times. If discount window loans were the cheapest funding available, banks would lean on them permanently and hold fewer liquid assets of their own, a moral hazard problem. Pricing above market rates means only a bank genuinely shut out of private funding shows up, and it leaves as soon as markets reopen.
