Lesson 9 of 14

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#

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

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

The control failures#

FailureExplanation
No separation of dutiesLeeson controlled both trading and settlement, so he could hide trades. See Operational and Model Risk
Unreconciled accountsThe error account was not properly investigated. See Trade Accounting and Reconciliation
Unquestioned profitsLarge reported profits from "low risk arbitrage" did not raise enough suspicion
Funding without understandingLondon sent large sums to Singapore to meet margin calls without understanding why
Weak risk oversightNo effective independent limits or monitoring. See Risk, Position, Loss and Drawdown Limits
Ignored warningsInternal 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. See Lessons From Market Failures.

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.
  3. Independent checks matter, even for individuals: compare your records with broker statements. See 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.
