Nick Leeson hid losses in error account 88888 and sank Barings, a 233-year-old bank
Leeson ran both trading and settlement in Singapore, so no one checked his books. He hid bad bets in account 88888 until an £827M hole swallowed the bank.
Barings Bank · 1995-02-26
What happened
Barings Bank, founded in 1762, was Britain's oldest merchant bank — the institution that had financed the Napoleonic wars and the Louisiana Purchase. In 1992 it sent a young trader, Nick Leeson, to run its futures desk on the Singapore International Monetary Exchange. Crucially, Leeson was put in charge of both the front office (making the trades) and the back office (recording and settling them), so there was no independent check on what he was doing.
Leeson began making unauthorized speculative bets on the Nikkei index and hid the losing trades in an error account numbered 88888 — the 'five-eights' account — so they never showed up in London's reports. For a while the bets paid off and Leeson was celebrated as a star trader. Then on January 16, 1995, he placed a large bet that Asian markets would stay calm; the next morning the Great Hanshin earthquake struck Kobe and markets plunged. Leeson doubled down, betting on a recovery that never came.
By the time Leeson fled Singapore on February 23, 1995, leaving a note that read 'I'm sorry,' the hidden losses had reached £827 million (about $1.4 billion) — roughly twice Barings' available trading capital. The bank was declared insolvent on February 26 and was eventually sold to ING for a symbolic £1. A 233-year-old institution was destroyed by one trader and the absence of basic controls. Leeson was caught, convicted in Singapore, and served just over four years in prison.
Why it happened
- Leeson controlled both trading and settlement, so the person making the bets was also the one recording them — there was no independent verification.
- London management trusted the reported profits and ignored warnings, including that Leeson had been denied a UK broker's licence for fraud on his application.
- The error account 88888 let losses be parked off the reports indefinitely without triggering any review.
- Risk controls and segregation of duties — the basics of derivatives operations — were simply absent in the Singapore office.
The lesson
Never let one person both make the trades and record them. Segregation of duties isn't bureaucracy — it's the only thing standing between a bad bet and a hidden one that grows until it kills the firm.
Aftermath
Barings was sold to ING for £1 and ceased to exist as an independent bank. Leeson's autobiography Rogue Trader became a book and film, and the collapse became the canonical case for segregation of duties and operational risk in banking. Regulators worldwide tightened requirements for separating front and back office functions and for independent risk monitoring. The 'five-eights' account is still shorthand for what happens when no one is checking the books.
