Spain created vales reales (royal vouchers) in 1780 as government debt that also circulated in limited ways as paper money. The measure aimed to cover major fiscal shortfalls linked to Spain’s war spending during the American Revolutionary era and related conflict with Britain. These instruments later became central to the Banco de San Carlos’s mission of converting government paper into cash.
In 1782, the bank’s first governing meeting appointed Francisco (François) Cabarrús as director. Cabarrús was a key advocate for linking a new “official credit institute” to the management and circulation of vales reales. His leadership helped shape the bank as a tool for state finance and payments, not just private commerce.
On 2 June 1782, King Charles III authorized the Banco Nacional de San Carlos in Madrid. Although protected by the Crown, it was organized as a joint-stock company with private shareholders. Its key goals included supporting the state’s finances, helping circulate and cash out vales reales, and providing credit to trade and industry.
In its early years, the Banco de San Carlos began issuing Spain’s first true banknotes, known as cédulas. A surviving example is dated 1 March 1783, showing the move from government vouchers toward bank-issued paper. Public acceptance was limited, but the issue marked a major step in Spain’s early central-banking development.
Spain’s repeated confrontations with major powers—especially France and Britain—put heavy pressure on public finances. The Banco de San Carlos increasingly focused on supporting the Treasury and managing growing state obligations. This shifted the bank’s balance away from broad commercial lending and toward government survival finance.
The Peninsular War began in May 1808 after Napoleon’s intervention and the uprising in Madrid. The conflict disrupted trade, tax collection, and state administration, sharply increasing borrowing needs. These conditions worsened the financial position of institutions tied to the Treasury, including the Banco de San Carlos.
During and after the Napoleonic invasion, the Spanish state accumulated massive unpaid obligations to the Banco de San Carlos. One widely cited figure is more than 300 million reales owed to the bank, reflecting how deeply it had become entangled with government finance. These arrears helped drive the bank toward a restructuring solution rather than a simple recovery.
By the 1820s, Spain’s fiscal position and the bank’s balance sheet remained weak, with large government debts effectively unpayable. Policymakers pursued a reorganization to preserve useful banking functions—especially note issue and state finance—while clearing the old institution’s liabilities. This set the stage for creating a successor bank under a new charter.
On 9 July 1829, a Royal Warrant of Ferdinand VII created the Banco Español de San Fernando in Madrid, replacing the Banco de San Carlos. The new bank was designed as a bank of issue with authority to issue notes in the capital, and it took on the task of financing the government. This marked a formal transition in Spain’s early central-banking lineage.
In the 1829 agreement, the Banco de San Carlos effectively waived a very large amount the government owed it (reported as nearly 310 million reales). In exchange, shareholders received 40 million reales in shares of the new Banco Español de San Fernando. The swap aimed to restart banking operations by separating an unpayable state debt burden from the new institution’s workable capital base.
The Banco Español de San Fernando was created with the privilege to issue banknotes in the capital, and it held this privilege exclusively until 1844. Concentrating note issue in one institution was an early step toward central banking, even though the bank still served both public and private interests. The arrangement also reinforced the bank’s role as a main channel for Treasury finance.
By 1829, the Banco de San Carlos had ended as an operating institution, but its structure and problems shaped what came next. Its successor, the Banco Español de San Fernando, carried forward core central-banking functions—especially note issue and state finance—on a reorganized basis. This transition is treated as a key step in the institutional lineage that later became the Banco de España.
