Key points of this lesson, in order.
The Herstatt Collapse of 1974
What you will learn
Your objective. By the end of this lesson, you will be able to explain herstatt collapse of 1974. The most famous example of settlement risk is the collapse of Bankhaus Herstatt, a small German bank, on 26 June 1974.
Why it matters. An analyst uses Herstatt as a test, not just a story.
Chapter objective: Learner identifies settlement risk, including Herstatt risk, principal risk, and replacement cost risk, and explains mitigations such as payment versus payment, netting, and limits. Learner demonstrates this skill using realistic banking examples, explaining each step clearly and using correct terminology throughout.
Key learning points
- Famous example of settlement risk
- Herstatt failure exposed
- Decades-long Herstatt response
- See the mechanism with a simple case
- Amounts: large
- Which system settles first: the party that pays first carries the risk
Key terms
Settlement: The final movement of funds between banks to discharge obligations created by cleared payments. Settlement is usually made in central bank money or through correspondent accounts.
Finality: The point at which a payment settlement becomes irrevocable and unconditional, so it cannot be reversed by the payer or the system.

Exercise
Decide which settlement model fits the scenario in this lesson and explain why.
Use the settlement models, the liquidity trade-off and the finality rules in this lesson.
- What to do. Name the model, state when settlement becomes final, and explain what happens if the sending bank does not have enough liquidity.
Correct result. Real time gross settlement settles each payment individually in central bank money with immediate finality, but it needs liquidity for every payment. Deferred net settlement nets payments and settles the net position, which needs less liquidity but leaves settlement risk until the net settles.
Why. Settlement is where money actually moves. The model decides the risk, the liquidity need, and when the payment is truly final.
Check your understanding
Practice question
A bank sends funds to a foreign bank in the morning and expects the return leg the same day. The foreign bank fails before the return leg settles. What risk has crystallised?
Takeaway and next step
What to remember
Its counterparties had already paid their marks and never received their dollars.
Settle a payment like the one in this lesson and watch the liquidity and finality behaviour.
Builds on "What Settlement Risk Really Is".

The most famous example of settlement risk is the collapse of Bankhaus Herstatt, a small German bank, on 26 June 1974. Herstatt had been active in foreign exchange trading, and on that day it received Deutsche marks from its counterparties in Frankfurt during the German business day, as payment for dollars it was due to deliver in New York. Before the New York leg could settle, the German regulator closed the bank. Its counterparties had already paid their marks and never received their dollars. The loss was large, and it shocked the international banking system. The Herstatt failure exposed a basic flaw in foreign exchange settlement as it then operated. The two legs of a foreign exchange trade settled at different times and in different time zones, through different payment systems, with no link between them. A bank could pay its side in full and still lose everything if its counterparty failed in the hours between the two settlements. This time gap became known as Herstatt risk, and it is still the standard term for settlement risk in foreign exchange. The lesson was that settlement risk is not just about whether a counterparty is sound, but about when each leg settles. The response to Herstatt unfolded over decades. Banks improved their internal controls, regulators introduced new rules, and the industry built new infrastructure, including real time gross settlement systems and, eventually, CLS, which is covered later in this chapter. The Herstatt case remains a core teaching example because it is simple, dramatic and still relevant. Every modern discussion of payment versus payment, of settlement finality and of foreign exchange risk traces back to that one day in June 1974, when a small bank failure revealed a systemic weakness. See the mechanism with a simple case, because the history is easier to remember once the mechanics are clear. A bank pays DEM 40 million in Frankfurt in the morning for dollars it expects in New York in the afternoon. That is a normal foreign exchange trade, and the bank has done it a hundred times. On 26 June 1974 the German regulator closed Bankhaus Herstatt during the German afternoon, after it had received Deutsche marks from its counterparties but before it could deliver the dollars in New York. Every counterparty that had paid marks that day lost them, because the dollars never came. The amounts were large, but the lesson is not about the size. It is about the gap. The two legs settled hours apart, in different time zones, through different systems, with nothing linking them. A counterparty could be perfectly sound in the morning and gone by the afternoon, and the gap was long enough for that to happen. An analyst uses Herstatt as a test, not just a story. For every new foreign exchange flow, ask three questions. Are the two legs linked so that one cannot settle without the other. How long is the gap between them, in hours, and what could happen inside that gap. And which system settles first, because the party that pays first carries the risk. If the answers are no link, a gap of several hours, and our bank pays first, the flow needs payment versus payment, a settlement limit, or collateral before it goes live. The Herstatt case should sit in the risk register as the named precedent, so that when a developer asks why a limit exists, the answer is a date and a story, not a policy number.
