Overend Gurney Failed in 1866 and the Bank of England Learned Its Job
A large London discount house collapsed, panic followed, and the response established the principle that a central bank lends freely in a crisis against good collateral.
What Overend Gurney Was
Overend Gurney was one of the largest discount houses in London. Discount houses bought commercial bills at a discount to face value, providing short term finance to trade, and were central to the functioning of the money market.
The firm had a long established reputation and was regarded as one of the most secure institutions in the City.
How It Failed
The business moved away from its traditional short term bill discounting into longer term and considerably riskier lending, including to railway ventures and shipping.
Those investments deteriorated. The firm converted to a limited liability company in 1865, offering shares to the public at a point when its position was already weak, which later became a matter of legal proceedings.
In May 1866 it suspended payments, owing very large sums.
An institution funded by short term deposits and invested in long term illiquid assets is vulnerable regardless of its reputation. The reputation delays the run rather than preventing it.
The Panic
The failure of an institution of that standing produced immediate and severe panic. Depositors withdrew from banks across London, several other institutions failed, and interest rates in the money market rose dramatically.
The day of the collapse became known as Black Friday. The Bank of England raised its rate sharply and lent extensively, and the government suspended the Bank Charter Act, which restricted note issue relative to gold reserves, allowing the Bank to provide more liquidity than the law otherwise permitted.
What Bagehot Derived From It
Walter Bagehot, editor of The Economist, analysed this and earlier panics in his 1873 work Lombard Street, producing the framework still referenced today.
| Principle | Reasoning |
|---|---|
| Lend freely | Panic is a shortage of liquidity, not of value |
| At a high rate | Discourages use except in genuine need |
| Against good collateral | Distinguishes illiquid from insolvent |
| Announce the policy in advance | Certainty reduces the panic itself |
The distinction between illiquidity and insolvency is the heart of it. An institution with sound assets that cannot be sold quickly should be lent to, because forcing a fire sale destroys value that exists. An institution whose assets are genuinely worth less than its liabilities should be allowed to fail, because lending only postpones and enlarges the loss.
Making the policy known in advance matters because much of a panic is uncertainty about whether support will arrive. A credible commitment reduces the number of people who need to run.
Where the Doctrine Is Difficult
Distinguishing illiquidity from insolvency during a crisis is far harder than stating the distinction. Asset values in a panic are depressed precisely because of the panic, so an institution may look insolvent at distressed prices and solvent at normal ones.
The high rate condition has also been applied loosely in modern practice, where emergency lending has frequently been provided at rates that were not penal, on the reasoning that a penalty rate discourages institutions from borrowing until it is too late.
Why It Still Matters
Every modern central bank liquidity facility descends from this analysis. The discount window, emergency lending programmes, and the facilities created during 2008 and 2020 all rest on the same logic: provide liquidity against collateral so that solvent institutions are not destroyed by a temporary inability to sell assets.
The recurring difficulty is also the same one. Support that prevents a panic also protects institutions from the consequences of their decisions, and that tension has no clean resolution.
The Bottom Line
Overend Gurney failed in 1866 after moving from short term bill discounting into illiquid long term lending, triggering a severe London panic. The response and Bagehot subsequent analysis established the rule that a central bank should lend freely at a high rate against good collateral, and announce that it will. The framework is still in use, and the hardest part remains telling illiquidity from insolvency while it is happening.
