Overend Gurney and Black Friday 1866: How Bagehot's Rule Was Made

At the corner of Lombard Street and Birchin Lane, on the morning of Friday 11 May 1866, a crowd stood in the roadway looking at a closed door.

The building behind it was 65 Lombard Street, and the firm that had occupied it since the 1820s was known in the City simply as the Corner House. The name described a position in the street and a position in the market at the same time. Overend, Gurney and Company discounted commercial bills — it bought a merchant's promise to pay in three months for cash today, took the difference as its fee, and held the paper until it matured. Every country bank in England kept balances in Lombard Street against the day it needed cash, and a great deal of that money sat with the Corner House. One nineteenth-century account of the discount trade put its standing plainly: for forty years it was the greatest discounting-house in the world.

It had stopped paying at half past three the previous afternoon. Liabilities stood at about £11 million. Within hours the panic had reached Liverpool, Manchester, Norwich, Derby and Bristol, and The Times had given the day a name that stuck to it.

What the Gurneys Built

Quaker capital built the firm. Gurney's Bank of Norwich was among the most solid provincial houses in England, and when John and Samuel Gurney became partners in the London bill-broking business of John Overend in 1807, they brought East Anglian deposits and a reputation for caution to a trade that ran almost entirely on reputation. In 1827 the partnership took the name Overend, Gurney and Company. By then it was already the leading bill brokerage in London.

Samuel Gurney's method was conservative to the point of dullness. He bought short paper drawn against real goods in transit, he kept the portfolio liquid, and he did not lend against things that could not be sold quickly. During the crisis of 1825, when the Bank of England discovered by improvisation that somebody had to stand behind the market, the Corner House had been part of the solution rather than part of the problem — a distinction it repeated in 1847 and 1857. Its capital in the middle of the century has been estimated at several million pounds, at a time when the Bank of England's own reserve rarely ran much above that.

Samuel Gurney died in 1856. What happened over the following ten years is the part of the story that contemporaries found hardest to explain, because the men who took over were not strangers to the business and had watched him run it.

The Assets Nobody Could Sell

A discount house lives on the difference between short money and short paper. Its deposits are repayable on demand or at a few days' notice, so its assets must be capable of being turned into cash at roughly the value carried on the books. Break that match and the arithmetic stops working, whatever the quality of the individual investments.

Overend's successors broke it deliberately. Through the late 1850s and early 1860s the firm moved out of three-month trade bills and into long-dated, illiquid and frequently controlling positions in businesses that had come to it as borrowers and stayed as problems. It financed shipping lines. It took on railway contractors' paper of a kind that could not be sold at any price once the contractor stopped paying. It ended up owning a substantial share of the Millwall Iron Works on the Isle of Dogs, a shipbuilding and engineering concern whose losses in April 1866 alone came to around £500,000. There were Irish railway interests, a grain business, a fleet of ships.

W.T.C. King's history of the discount market treats this drift as the central fact of the failure — a house whose whole function was liquidity had ceased to be liquid, and none of its depositors knew (King, 1936). The firm's partners knew. By the early 1860s the deficiency on the old partnership was estimated at between £4 million and £5 million against a balance sheet of roughly £20 million.

Selling the Problem to the Public

In the summer of 1865 the partners did what a private firm with an unpayable hole in its books could now legally do. Limited liability had been generalised by statute a decade earlier, and the market for new company shares was running hot. Overend, Gurney and Company Limited was floated on the London Stock Exchange in August 1865, raising £5 million — £1.5 million paid up at once, with a further £3.5 million left uncalled as a reserve liability on the shareholders.

What the subscribers bought was the old firm's assets, the old firm's name, and the old firm's deficiency. The prospectus did not disclose that the business being purchased was insolvent by something close to the entire amount raised. Shares went to a premium on the first day of dealings.

Geoffrey Elliott's study of the affair, built on the surviving partnership records, describes a transaction whose participants told themselves that a rising market and a few good years would close the gap before anyone had to look (Elliott, 2006). The market did not rise. Rates tightened through 1865 and into 1866 as gold moved out of London, a run of company failures in the spring exposed the contractors' paper, and by early May the Corner House was paying out deposits it could not replace.

On Wednesday 9 May the directors went to the Bank of England and asked for an advance of £400,000. The Bank sent officers to examine the securities, and on Thursday 10 May it declined. Overend, Gurney and Company Limited suspended payment that afternoon, ten months after its flotation.

Ten Days in May

Bank Rate had been 6 per cent at the start of the month. It rose four times in ten days.

Friday was the worst day the London money market had seen. Crowds filled Lombard Street. Banks that had lent to the discount houses found their own depositors at the counter, and the demand for cash at the Bank of England's discount window ran at a rate the Banking Department's reserve could not meet under the rules it was obliged to follow.

Those rules were the Bank Charter Act of 1844, which split the Bank into an Issue Department and a Banking Department and forbade the issue of notes beyond a fixed fiduciary amount unless they were backed pound for pound by gold. In a panic the effect was perverse: the more the public wanted notes, the less capacity the Bank had to supply them, and the statute designed to prevent monetary excess became a constraint on the one institution able to stop a run.

The Chancellor's Letter

Twice before — in 1847 and 1857 — the government had solved this by writing a letter. On the afternoon of 11 May 1866 it did so again. William Gladstone, Chancellor of the Exchequer, authorised the Bank to exceed the statutory note issue and promised legislation to indemnify it, on one condition: the minimum rate of discount was to be raised to 10 per cent.

The Bank lent. More than £3 million went out on the day after the suspension, and roughly £10 million during the first week of the crisis — more than double its normal level of accommodation. Flandreau and Ugolini, working through the Bank's own discount ledgers rather than the published accounts, found that the lending was broad rather than selective: the Bank discounted for a wide range of counterparties, took what collateral was offered, and priced the accommodation punitively instead of rationing it (Flandreau and Ugolini, 2013). The note issue never in fact exceeded the statutory limit. Publishing the permission was enough.

Walter Bagehot, then editing The Economist, understood immediately what the letter had done to the constitutional position of the Bank. Its effect, he wrote, was to confirm "the popular conviction that the Government is behind the Bank, and will help it when wanted".

Bank Rate stayed at 10 per cent until 16 August, a plateau of three months. Money was dear for the rest of the year, and the commercial contraction that followed was severe enough to be felt in the shipbuilding towns for a decade.

What Broke Next

More than two hundred companies failed in the wake of the suspension, and the casualty list among the joint-stock banks of the 1860s boom was worse than that figure suggests. Only about one in six of the joint-stock banks founded since 1844 came through the crisis. Agra and Masterman's Bank, formed by amalgamation only the previous year and heavily committed to Australian and Indian railway finance, suspended on 6 June. The Consolidated Bank stopped and reopened. The Bank of London survived on emergency advances. The Economist, surveying the wreckage, attributed the principal bank failures to unsound financing and named the Bank of London and Agra and Masterman's specifically.

Britain would not see a queue outside a bank on that scale again until depositors lined up at Northern Rock branches in September 2007, and the interval between the two events is the measure of what 1866 settled.

The Trial

Shareholders who had bought into the 1865 flotation, and who now faced calls on the £3.5 million of uncalled capital, wanted somebody prosecuted. In January 1869 six directors of Overend, Gurney and Company Limited were committed for trial on a charge of conspiracy to defraud, in one of the first great criminal proceedings arising out of a company failure.

Everything turned on the prospectus — on whether the directors had known the business they were selling was insolvent, and whether omitting that from the offer document amounted to fraud rather than negligence. In December 1869 all six were acquitted. The jury accepted that the men had been foolish rather than dishonest, and the law of the day gave a prosecutor very little with which to argue otherwise. Nothing in the statute book then required a prospectus to state what the promoters knew about the value of what they were selling.

That gap took another generation to close, and the closing of it came in instalments through the Directors' Liability Act 1890 and the prospectus provisions of the Companies Acts that followed. The pattern repeats across the corpus: a court finds no crime, and Parliament writes one.

What Bagehot Made of It

Bagehot spent the seven years after Black Friday arguing that the Bank of England should stop pretending to be an ordinary commercial bank with an unusually large reserve. His book Lombard Street appeared in 1873, and its argument was descriptive before it was prescriptive: the Bank already held the only reserve the country had, everybody in the City knew it, and the sensible course was to admit the fact and act on it in advance rather than under a letter from the Treasury (Bagehot, 1873).

The rule he set out has three parts. Lend freely. Lend on collateral that would be good security in ordinary times. Charge a high rate, so that the accommodation is genuinely a last resort and the gold does not leave the country. Against a panic, he wrote, the Bank should lend "freely and vigorously to the public out of the reserve", and hesitation would be punished — the market would impose what he called a heavy fine on unreasonable timidity.

Every part of that had been visible in May 1866, though not as policy. The Bank had lent freely, at a rate the Chancellor set at 10 per cent, against whatever paper was brought in — and it had done so only after refusing to save the largest discount house in the world, which is the other half of the doctrine and the half most often forgotten. Schneider's reconstruction of the political manoeuvring around the letter argues that the Bank's directors were considerably less sure of their ground at the time than the later doctrine implies, and that the decision to let the Corner House go was contested inside the Bank rather than a settled application of principle (Schneider, 2022).

The distinction the Bank drew in 1866 is the one central banks still work with. An insolvent firm is not rescued; the market it borrowed from is kept open. The same line was drawn, with more argument and less clarity, when the Federal Reserve financed JPMorgan's purchase of Bear Stearns and then declined to save Lehman Brothers six months later. It had first been improvised during the crisis that followed the Latin American loan boom of the 1820s, when the Bank discovered the role without a name for it, and it was applied with far greater confidence a generation after Overend Gurney, when the Bank organised a guarantee fund to absorb Barings' Argentine losses in 1890 without letting the house fail at all.

Overend, Gurney and Company was wound up over the following years. The estate paid its creditors a fraction of what they were owed, the uncalled capital was called, and a number of the shareholders who had subscribed in August 1865 were ruined by the calls rather than by the collapse.

The Corner House itself was let to other tenants. Bagehot, who had walked past its door for most of his working life and who took the firm's standing in the City as the starting point of his analysis, disposed of the men who ran it in a single sentence: the losses, he wrote, "were made in a manner so reckless and so foolish, that one would think a child who had lent money in the City of London would have lent it better".
