Overview
Herstatt Bank, formally Bankhaus I.D. Herstatt K.G.a.A., was a privately owned German bank based in Cologne. Founded in 1955 by Ivan David Herstatt with financial support from industrialist Herbert Quandt, Swiss industrialist Emil Bührle and insurer Hans Gerling, the bank expanded during a period of rapid growth in German banking and became an active participant in international foreign-exchange markets. By 1974, Herstatt had grown to become the 35th-largest bank in Germany, with assets exceeding DM2 billion. Its business included conventional banking activities as well as substantial foreign-exchange dealing. The sharp volatility of the U.S. dollar in 1973 and 1974 exposed the institution's weak capital position and speculative risk-taking. Herstatt made unsuccessful bets on the direction of the dollar and had accumulated losses of approximately DM470 million by June 1974, while its capital was reported at only about DM44 million. German regulators forced the bank into liquidation on 26 June 1974. The timing of the closure created an especially damaging cross-border payment problem. Several banks had already delivered Deutsche Mark payments to Herstatt in Frankfurt in exchange for U.S. dollar payments that were expected later in New York. Herstatt was shut at 16:30 German time, corresponding to 10:30 in New York. Because the bank ceased operations between the two legs of the transactions, counterparties that had paid Deutsche Mark did not receive the dollars they were owed. The episode became known as the Herstatt crisis and gave its name to Herstatt risk: the possibility that one party to a foreign-exchange transaction pays the currency it sold but does not receive the currency it purchased because the counterparty fails during the settlement window. The failure demonstrated that a bank operating in one jurisdiction could create material risks for institutions and payment systems in another jurisdiction, particularly when settlement processes were not synchronized across time zones. The collapse had consequences far beyond the bank itself. In Germany, the Liquidity Consortium Bank was established later in 1974. Internationally, central banks and regulatory authorities from the G-10 countries, together with Luxembourg and Spain, formed the Basel Committee on Banking Supervision under the auspices of the Bank for International Settlements. The crisis also contributed to work on real-time gross settlement systems, in which payments are processed individually and become final in real time. Concerns about foreign-exchange settlement risk re-emerged in the late 1980s and 1990s as currency trading expanded. Those efforts ultimately contributed to the creation of CLS Bank, which began operating in 2002. Its payment-versus-payment model allows the two currency legs of eligible foreign-exchange trades to be settled in a coordinated manner, reducing the risk that one side pays while the other side is not delivered. Herstatt Bank therefore remains historically significant less as a continuing financial brand than as a case study in banking failure, supervisory coordination and payment-system design.
History
Herstatt Bank was established in Cologne in 1955 as Bankhaus I.D. Herstatt K.G.a.A. by Ivan David Herstatt. Its early development was supported by several prominent financiers and industrial figures, including Herbert Quandt, Emil Bührle and Hans Gerling. Gerling, who headed an insurance company, became the bank's majority shareholder. The institution remained privately owned rather than becoming a widely held public company. During the postwar expansion of the German economy, Herstatt grew beyond the scale of a small local bank. It developed an important presence in foreign-exchange dealing and participated in transactions involving major currencies. By 1974, the bank had assets of more than DM2 billion and ranked as Germany's 35th-largest bank. Its growth, however, was accompanied by substantial exposure to currency movements and by a capital base that was small in relation to the risks being taken. The U.S. dollar was unusually volatile in 1973 and 1974. Herstatt took positions based on expectations about the dollar's direction, but those positions turned out badly. By June 1974, reported losses from foreign-exchange activity had reached roughly DM470 million, compared with capital of approximately DM44 million. The imbalance left the institution unable to absorb its losses and vulnerable to regulatory intervention. On 26 June 1974, German authorities ordered Herstatt into liquidation. The closure created a cross-border settlement failure because foreign-exchange transactions were completed in two geographically and temporally separate stages. Banks had released Deutsche Mark to Herstatt in Frankfurt and expected dollar payments in New York. The German closure occurred at 16:30 local time, before the New York leg of the transactions had been completed. As a result, counterparties that had already paid one currency did not receive the other. The incident became known as the Herstatt crisis. Its central lesson was that a bank could fail during the interval between the payment of one currency and receipt of another. This form of principal or settlement risk became known as Herstatt risk. The episode also showed that national supervision and payment arrangements were inadequate for increasingly international banking operations. The policy response began later in 1974. Germany created the Liquidity Consortium Bank, while the central banks and supervisory authorities of the G-10 countries, joined by Luxembourg and Spain, established a standing committee at the Bank for International Settlements. This body became the Basel Committee on Banking Supervision. The crisis also helped motivate the development and broader use of real-time gross settlement, which processes payments individually and provides finality without relying on delayed net settlement. Although the immediate event occurred in 1974, its implications continued to influence financial infrastructure. Foreign-exchange settlement concerns returned to prominence as international currency trading expanded during the late twentieth century. The resulting policy and industry work eventually led to CLS Bank, which became operational in 2002. Its payment-versus-payment process coordinates the delivery of both currency legs and is intended to prevent the unilateral exposure that characterized the Herstatt episode. The bank itself is defunct, but its name remains embedded in the vocabulary of international payments, banking supervision and foreign-exchange risk management.

Products and positioning
A privately owned German bank that developed a significant foreign-exchange business before its 1974 failure. Its historical importance derives from the systemic settlement-risk problem associated with its collapse rather than from an enduring consumer-facing brand.
Foreign-exchange services
Foreign-exchange dealing
Foreign-exchange activity was Herstatt Bank's most historically consequential business. The bank took positions in major currencies, including the U.S. dollar, and became a significant participant in international currency markets. Losses on these positions during the volatile market conditions of 1973 and 1974 contributed directly to its collapse and exposed the settlement timing risk later called Herstatt risk.
Banking · 1955
Commercial banking
As a German privately owned bank, Herstatt provided broader banking services in addition to its market activities. The available reference material does not specify a complete catalogue of deposit, lending or corporate-banking products, but the bank's asset scale and counterparties indicate that it operated beyond a narrowly local retail model.
Controversies
1974
Herstatt crisis and foreign-exchange settlement failure
The bank's failed currency positions led to losses far exceeding its capital and culminated in regulatory liquidation. Because counterparties had paid Deutsche Mark before the corresponding U.S. dollar leg was completed, the collapse became a defining example of cross-border settlement risk and gave rise to the term Herstatt risk.
