Barings Bank, founded in 1762, was Britain's oldest merchant bank, a firm that had financed the Louisiana Purchase and counted the royal family among its clients. In February 1995, it collapsed because of the unauthorised trading of one employee, Nick Leeson, in its Singapore office. Leeson had hidden mounting losses in a secret account for more than two years, and when a Japanese earthquake sent markets tumbling, the losses reached about £827 million, more than the bank's entire capital. Barings was sold to the Dutch bank ING for £1. The case remains the textbook example of operational risk and failed controls.

## How it happened

| Period | Event |
|---|---|
| 1992 | Leeson starts running Barings' futures operations in Singapore, handling both trading and back office settlement |
| 1992 to 1994 | He hides losses in error account 88888, reporting large fictitious profits to London |
| 17 January 1995 | The Kobe earthquake hits Japan; the Nikkei falls sharply |
| January to February 1995 | Leeson doubles down, buying more Nikkei futures and selling options betting on stability |
| 23 February 1995 | Leeson flees Singapore |
| 26 February 1995 | Barings is placed into administration |
| March 1995 | ING buys Barings for £1 and takes on its liabilities |
| December 1995 | Leeson is sentenced in Singapore to six and a half years in prison |

## The positions

Leeson was supposed to run low risk arbitrage between Nikkei futures on the Singapore and Osaka exchanges. Instead, he took large unauthorised directional bets:

- **Long Nikkei 225 futures,** betting the Japanese market would rise.
- **Short straddles** on the Nikkei, selling options that profit if markets stay calm and lose heavily on big moves. See [Straddle](https://learn.tradelabsai.com/options/straddle/) and [Short Put](https://learn.tradelabsai.com/options/short-put/).

The Kobe earthquake caused exactly the large downward move that hurt both positions.

**Example: How doubling down deepened the hole**
After the earthquake, the Nikkei fell from around 19,000 to below 18,000. Rather than cutting his losing long futures position, Leeson bought more, apparently trying to support the market and win back losses. When the index kept falling, each additional contract added to the losses. This is the same behaviour as revenge trading and averaging down without limits, but with a bank's capital and no one checking.

## The control failures

| Failure | Explanation |
|---|---|
| No separation of duties | Leeson controlled both trading and settlement, so he could hide trades. See [Operational and Model Risk](https://learn.tradelabsai.com/portfolio/operational-and-model-risk/) |
| Unreconciled accounts | The error account was not properly investigated. See [Trade Accounting and Reconciliation](https://learn.tradelabsai.com/industry/trade-reconciliation/) |
| Unquestioned profits | Large reported profits from "low risk arbitrage" did not raise enough suspicion |
| Funding without understanding | London sent large sums to Singapore to meet margin calls without understanding why |
| Weak risk oversight | No effective independent limits or monitoring. See [Risk, Position, Loss and Drawdown Limits](https://learn.tradelabsai.com/portfolio/risk-limits/) |
| Ignored warnings | Internal audit had raised concerns that were not acted on |

## Aftermath

The Bank of England's investigation criticised Barings' management for serious control failures. The case led banks worldwide to strengthen separation between front and back offices, independent risk management and reconciliation. Similar patterns appeared in later rogue trading cases, including Jérôme Kerviel at Société Générale in 2008 and Kweku Adoboli at UBS in 2011.

## Lessons for traders

1. **Losses hidden grow larger:** acknowledging a loss early limits damage.
2. **Never double down to win back losses.** See [Loss Aversion](https://learn.tradelabsai.com/psychology/loss-aversion/).
3. **Independent checks matter,** even for individuals: compare your records with broker statements. See [Record Keeping for Traders](https://learn.tradelabsai.com/industry/record-keeping-for-traders/).
4. **Profits that seem too good** for the stated strategy deserve scrutiny.
5. **Selling options for steady income** can hide catastrophic risk. See [Fat Tails](https://learn.tradelabsai.com/math/fat-tails/).
