Banesto's €3.6B hole — the Spanish bank that hid its losses with accounting tricks

Banesto was Spain's third-largest financial group when Mario Conde became executive chairman in December 1987. Conde pursued an aggressive expansion, acquiring Banco del Pacífico in 1991 and Banco de Concepción in 1993. He also planned, with J.P. Morgan, a $1.2 billion rights issue and asset sales that would have made Banesto the largest financial firm in Europe. The plan was accepted by the Bank of Spain, but only because the bank's true condition was hidden.

Conde masked the bank's deteriorating loan portfolio by channelling profits from asset sales into reserve accounts rather than reporting them as income. This created the appearance of financial stability while the bad loans grew. By December 1993, the Spanish government observed sharp increases in loan delinquencies. The CNMV suspended trading in Banesto shares after the stock fell 6.8% in a single day — from 2,135 to 1,995 pesetas.

On December 28, 1993, the Bank of Spain intervened. The patrimonial shortfall was tentatively estimated at €3.6 billion — roughly $7.2 billion at the time. Conde was removed and replaced by a board of five other banks. In April 1994, Banco Santander won the auction for Banesto with an offer of 313.5 billion pesetas ($2 billion), making Santander Spain's largest financial group. Conde was sentenced to 20 years in prison for fraud and served 11.

Conde hid bad loans by diverting asset-sale profits to reserves, not income; the €3.6B hole emerged, the Bank of Spain seized the bank, and Conde got 20 years.

Conde used asset-sale profits to cover bad loans rather than reporting them — the bank appeared healthy while the hole grew. This is the oldest trick in banking, and it worked because nobody looked.

The Bank of Spain accepted Conde's restructuring plan with J.P. Morgan without verifying the bank's true condition. The intervention came months later, after the hole had grown to €3.6 billion.

Conde's aggressive expansion — acquiring two banks in three years — created a portfolio too large to manage transparently. The acquisitions were financed with debt that the bank could not service.

Conde was not just a Banesto fraudster — he was also convicted in the Argentia Trust case, showing a pattern of financial misconduct that extended beyond one bank.

When a bank channels profits from asset sales into reserves instead of reporting them, it is not being prudent — it is buying time. The bill always comes due, with interest.

Banesto was absorbed into Santander in 2012 — nearly 20 years after the intervention. Conde served 11 years of his 20-year sentence before parole. The case became a symbol of Spain's lax banking oversight in the 1980s and 1990s, when aggressive expansion and accounting tricks were tolerated as long as the numbers looked good. Santander's acquisition of Banesto transformed it into Spain's largest bank, a position it has held since. Conde's legal troubles continued after his release — in 2016 he was arrested again for alleged fraudulent capital transfers related to a cosmetics company.
