A Bank That Survived 233 Years Was Sold for £1. The Trader Who Broke It Settled His Own Trades.

Barings helped broker the Louisiana Purchase and banked the British crown. It died because a desk in Singapore let one man place the bets, report the profits, and shred the duplicate slips.

Barings was founded on Christmas Day 1762, and within four decades it was so central to European finance that a contemporary called it "the sixth great European power," after England, France, Prussia, Austria, and Russia. In 1803, with a Dutch house, it brokered the Louisiana Purchase, technically buying the territory from Napoleon and reselling it to the United States, even though Britain was at war with France. It was the Queen's bank. It survived the Napoleonic Wars, two world wars, and 233 years of panics.

It did not survive a 28-year-old former back-office clerk in Singapore.

Nick Leeson had processed trades at Coutts and at Morgan Stanley before joining Barings in 1989. In 1992 the bank sent him to run a new derivatives desk on the Singapore International Monetary Exchange. His job was meant to be almost riskless: buy Nikkei 225 stock-index futures in Singapore, sell the identical contract in Osaka a split-second later, and pocket the tiny price gap. Pure arbitrage. No net position, no view on where the market was going.

The fatal structural decision was that Barings also put him in charge of the back office, the settlements team that recorded and reconciled those same trades. The person taking the risk and the person checking the risk were the same person. An internal fax in March 1992 warned the setup "will prove disastrous." It was filed and forgotten.

Within days of starting, Leeson opened an "error account," numbered 88888, meant for parking minor clerical mistakes. He had it excluded from the reports London saw and told his settlements staff to shred the duplicate slips. Into 88888 went every losing bet. The hidden losses climbed from £2 million at the end of 1992 to £23 million in 1993 to £208 million by the end of 1994.

Meanwhile the desk he ran reported bumper profits. Barings' draft 1994 accounts showed a £102 million pre-tax profit, with an equal £102 million tucked into the staff bonus pool. Leeson's supposedly riskless arbitrage generated over 60 percent of the bank's worldwide derivatives revenue. Nobody wanted to look too closely at the golden goose. London happily wired him ever-larger sums for "margin," believing the positions belonged to a client.

It was never arbitrage. Leeson was running a one-way bet that the Nikkei would rise, financed by selling options and by cash from head office. When he lost, he doubled the bet, the classic martingale that works until it meets a losing streak you cannot fund. By February 1995 he held 49 percent of the open interest in the March Nikkei contract.

The streak arrived on January 17, 1995, when a magnitude-7.2 earthquake devastated Kobe. The Nikkei cracked. On January 23 it plunged more than a thousand points. Leeson was long the market and had sold options betting it would not move, so every leg bled at once. Instead of cutting, he doubled again, betting on a rebound that never came. In his final weeks London funneled him nearly $900 million for margin, more than the bank's entire capital.

On February 23 he left a note reading "I'm sorry" and fled. The Bank of England spent a weekend trying to assemble a rescue, but no buyer would take on the open, uncapped losses. On February 26, 1995, Barings was declared insolvent. The Dutch bank ING bought the operating businesses for a nominal £1 and committed roughly £660 million to recapitalize them; the Baring family's stake and the holding company's bonds were wiped out. Leeson was arrested in Frankfurt, extradited to Singapore, and sentenced to six and a half years, of which he served four.

The Bank of England's own investigation concluded that derivatives' complexity was not what killed Barings. The contracts were simple. What killed it was letting the man who took the risk also write the report on the risk, paired with an incentive structure in which no one could afford to question a profit line that was too big and too good. A profit you are not allowed to examine is the loudest warning you will ever get. If the person placing the bets can also settle them, you do not have a trading desk. You have a casino with one employee.
