# One Trader Defaulted. Forty-One Firms Paid €114 Million In Nine Days.

*We read 2,908 pages of default-management rules at six clearing houses and coded all seventy-one powers in them. Exactly one has ever been exercised. The four that reach furthest into a surviving member's money have never been used at all.*

In fifty years, the powers that let a clearing house reach into a surviving member's money have been used once.

We read the default-management chapters of six clearing-house rulebooks end to end — 2,908 pages — and coded every power in them: what triggers it, whose money it reaches, and where the book says it stops.

Seventy-one powers. Six waterfalls. One use.

The use was Stockholm, in September 2018, and it cost the survivors €114 million.

## What the book actually allows

A clearing house stands between every buyer and every seller. Once a trade is registered the two sides no longer face each other; they both face the house, which owes the winner and is owed by the loser. That is the whole service, and it works until a member cannot pay.

The rulebook then says who does pay, in order. The order is called the waterfall.

The first three steps are uncontroversial. The defaulter's margin. The defaulter's own contribution to the mutual fund. Then a slice of the clearing house's own capital.

Below that line the money stops being the defaulter's and starts being everybody else's, and four powers live there. A cash call on the survivors. The haircutting of gains — the house pays a member less than it owes him on a position that won. Forced allocation, which hands a member part of the defaulter's book whether he wants it or not. And at the bottom, partial tear-up: the cancellation of live contracts, including profitable ones, at a price the house sets.

Four of the six rulebooks number this article in the 800s. We have used 802 throughout because it is the number in the one book that has been tested.

## Stockholm, 10 September 2018

Torbjörn Sahlgren-Vik was a member of Norrklar in his own name — one of nine individuals in Europe then cleared without a firm behind them. He had been a member for eleven years. He held a spread between Nordic and German power, and on 10 September the spread moved seventeen per cent the wrong way.

His margin was €138 million. It was gone by Tuesday afternoon. His own contribution to the fund, €7.1 million, went with it.

Then €7.4 million of Norrklar's own capital.

Then €114 million of the €166 million that the other forty-one members had paid in.

Rule 802(a) was invoked at nine in the morning on the Wednesday. Replenishment notices went out the same hour — €114 million, pro rata across the forty-one survivors, payable in five business days. Every member paid. The last wire landed nine calendar days after the first notice and one firm paid a day early.

Nothing below 802(a) was reached. No gains were haircut. Nothing was torn up.

> I had not read the eight hundreds before the notice arrived. It was four pages. It told me what I owed and by when, and it was right.

## The number that is not in the rulebook

Here is what we did not go looking for.

Norrklar's own €7.4 million stood in front of €166 million of its members'. Four and a half per cent.

No rule sets that figure. No regulator approves it. It is decided by a board, minuted in a sentence, disclosed in a table without a percentage beside it, and it has never once had to be explained to the members whose money sits directly underneath it.

We asked all six clearing houses how theirs is arrived at. Two gave us a number and the board minute behind it. One gave a range, which cannot be compared with a number. Three said it was a matter for the board.

Professor Nkiruka Aderinto-Falk, who checked our coding, thinks the ratio we have chosen is the wrong one and prefers a measure against annual clearing revenue. On her measure Norrklar looks better. We publish her working beside ours because we would rather print the objection than pick the flattering denominator.

## The consultation nobody answered

In three of the six rulebooks the definition of an *affected contract* — which decides how much of a market a tear-up could reach — was widened by technical amendment. Twenty-eight days, thirty days, forty-two days. Each consultation drew no responses.

None from a member. None from a trade body. None from us, and we had read the book.

## What we could not make frightening

The clause exists. It is real, it is enforceable, and a reader is entitled to be told it is there.

It has also been invoked once in the lifetime of the institution, it operated exactly as printed, on the schedule printed beside it, and the people it fell on paid in nine days and went back to work.

The thing worth being uneasy about is four and a half per cent, and it is not in the rulebook at all.

## Sources (invented)

- Six clearing-house rulebooks, default-management chapters, 2,908 pages, current text plus every amendment since 2009 — Downloaded from the six public rule libraries; coded twice, independently, by two readers who compared only at the end (March–July 2026)
- Anneli Sjögren-Bratt, Head of risk at Norrklar 2014–2021; now teaches — Interviewed by video call three times, then sent the draft; corrected two figures in it (May and July 2026)
- Roeland Vissers-Kappel, Group treasurer of a Rotterdam energy trading firm; a surviving member — Interviewed at his office; showed us his firm's call notice and the ledger entry against it (June 2026)
- Prof. Nkiruka Aderinto-Falk, Financial regulation, Rotterdam; works on central counterparty capital — Commissioned to review our coding sheet against her own dataset and to write down where we were wrong (July 2026)
- Torbjörn Sahlgren-Vik, The defaulting member — Written to twice at an address supplied by his former counsel; no reply, and no approach made through his family (April and June 2026)

## What we could not confirm

- Whether six rulebooks are enough. There are more than forty clearing houses of consequence. We read the six whose default-management chapters are published in full; two of the largest publish a summary and a page count, and a summary cannot be coded. Our seventy-one powers are seventy-one powers in six books, not a census.
- Whether the €7.4 million is current. It is the figure that stood in September 2018 and it is the figure Norrklar's 2025 disclosure repeats. The disclosure standard permits the number to be given as a range, and one of the six gives it as a range, which means we cannot put that clearing house on the same chart as the others and have not tried.
- Whether the tear-up limb has genuinely never been used. We can only say it has never been disclosed. Two clearing houses told us in writing that they have never invoked it, three did not answer the question, and one declined to discuss hypothetical scenarios, which was not the question we asked.

## Right of reply

**Bengt Ohlmark-Ceder, chief executive, Norrklar Clearing AB** (Replied 29 July 2026. Printed in full and unedited, including the paragraph about us.):

> You have read two thousand nine hundred and eight pages of my industry's rules and reduced them to one number, and I want to explain why it is the wrong number before I concede the part where you are right.
> 
> The €7.4 million is a tranche in a waterfall. It is not the whole of my house's money at risk and it never was. My members' exposure is bounded — it is bounded by the rulebook you have just read, in a schedule with a total at the bottom of it. Mine is not bounded. If this clearing house fails there is no clearing house, there is no equity, there are eleven hundred contracts with nobody in the middle of them, and I do not get to stop at four and a half per cent. Comparing a tranche to a fund and calling the ratio a governance choice is arithmetic in search of a scandal.
> 
> Now: you will say, raise it anyway. Put eighty million in front of the fund instead of seven. I am asked this at every conference and the answer is always the same and nobody prints it. Where does the eighty million come from? It comes from a capital raise, which is serviced by fees, which are paid by the same members whose fund you want it to protect. You are proposing that my members insure themselves through me and pay me a margin for the administration. That may still be worth doing. It is not free, it is not a moral question, and describing it as skin in the game does not make the money appear.
> 
> On the 2018 default I will say two things and then leave it alone. The first is that the rulebook did what it says. It did it in daylight, at published times, at a pro-rata share every treasurer could check against his own screen, and the money was in nine days later. I have run this house for eleven years and that is the only week I am sure about.
> 
> The second is about the man. He was not reckless in the way people mean when they say reckless. He was concentrated, in a spread that had behaved for a decade, and he was a professional who had read the rules he was cleared under. Your newspaper has been careful with him and I noticed, so I will be careful too: he lost more than money and he is not a lesson.
> 
> On the tear-up, which your draft led on and your printed page does not. Yes, I can tear up a live contract. So can every clearing house on earth, and so could the exchanges that came before them, and the alternative to that power is not a market in which nobody is ever made worse off — it is a market in which the house fails and everybody is. You had written the sentence so that a reader finished it frightened, and then you spent six paragraphs undoing it. I would rather you had written the sixth paragraph first. I am told you now have.
> 
> And one last thing, which I say without much pleasure. Three of my colleagues widened the definition of an affected contract by technical amendment and you report, correctly, that the consultations drew no responses. They drew none from you either. Your finance editor read my rulebook cover to cover this spring. The consultation was open for forty-two days in 2022 and four lines from a serious newspaper would have been on the agenda of a meeting I chaired. Nobody sent four lines. I do not think that is a defence of us. I think it is a fact about how this happens.
