The CDS market is pricing in an approximately 10% chance of $CS failing in the next year.
The spread can be solved using the inverse S = ln ( 1 - P ) * ( ( R - 1 ) / t )
Probabilities and rates are both expressed as percentages not basis points.
S is the spread. t is years. R is the recovery rate.
Source is my notes from undergrad. Options, Futures, and Other Derivatives (9th Edition) by John C. Hull. Take all this with a grain of salt as I am not a quant. (but I am looking for a job!)
Doing some additional reading, there are some more precise approximations but they are less general.[1]
Last number I was able to pull up the $CS CDS was trading at 551 BP. Up from 446 yesterday (an all-time high for $CS)
Lehman Bros hit 640 BP just days before collapse.

Weird thing about the recovery rate is that everyone I've asked says the same thing, and I've traded CDS: the recovery rate is 40%. It's a bit of a free variable in that equation, and it matters. Trouble is how on earth do you estimate it? But random people I've met in the business will just say 40%, for every issuer, somehow.
We are living in times of idiosyncratic risk and my approximations above are likely no better than hearsay.
That being said I'm not rushing to buy or sell $CS stock even with my elevated risk tolerance and the seemingly low price.
My mental picture is a very unsteady hub and spoke like in Wipeout or something where the parties and counter parties are intertwined in ways that the dynamics are, as you put it, idiosyncratic.
Edit: I asked ChatGPT. "The recovery rate of a credit default swap (CDS) is typically specified in the contract and agreed upon by the parties involved. The recovery rate is the percentage of the notional value of the underlying debt that the protection buyer would receive in the event of a credit event, such as a default, of the reference entity.
To find the recovery rate of a specific CDS contract, you can refer to the contract documentation, which should include details on the recovery rate. This information may also be available from the CDS provider or through financial data providers such as Bloomberg, Reuters, or other financial news sources.
It's worth noting that the recovery rate can vary depending on the specific CDS contract, the reference entity, and the prevailing market conditions. Therefore, it's important to confirm the recovery rate specified in the contract and to keep track of any changes in the market or credit conditions that could affect the recovery rate."
To answer your question, "idiosyncratic risk" in this context means that an individual company might have problems that don't broadly apply to the rest of its industry. For example Credit Suisse might have management that is bad at running a bank, leading to repeated investment losses and regulatory actions well beyond what's normal for big multinational banks.
Look at the CS balance sheets over the past few years, or its stock price and PE ratio, or hell just Google "Credit Suisse books loss" and look at how many times they tried to stick their fingers in the wrong cookie jar. They got hit by the Hwang thing, they got hit by Greensill, and apparently they can't even accurately report how much money they're making (losing).
I wouldn't want to have any position on their equity either.
I’d also welcome any interesting further reading on the subject!
However, if you’d like to learn more about $CS and Archegos I’d recommend reading the Report put out by $CS on the topic.
Colloquially known as, “Credit Suisse Group Special Committee of the Board of Directors Report on Archegos Capital Management”
https://www.sec.gov/Archives/edgar/data/1159510/000137036821...
It’s all about the material risks Archegos posed to Credit Suisse.
CS failed to capture a number of specific risks which were intrinsic to Archegos’ specific trading strategy. I won’t go through them all but they explicitly call out “idiosyncratic risk” due to their use of equity total return swaps, baskets of them, to hide equity positions. The risk being if the components of the basket, which were may have been billed to be diversified, all the sudden begin to move violently and in sequence, it would be a material idiosyncratic risk to $CS.
A large number of these swaps from 2021 are coming due this week and next. Including likely a large number today, March 15, which is a commonly used date for expiry of EuroDollar and Forex contracts, as well as presumably equity swaps as well?
Now, what’s in those swaps? Who knows, the CFTC announced an exemption back in 2021 allowing NO REPORTING of swaps through at least the fall of this year, which has subsequently been extended through 2025. So we shall see how the dominoes fall and only after will they let us see how they were setup.
A peculiarity of finance as a field of study is that a lot of the people studying finance only care about direct applications and a lot of the people teaching finance had this mindset when they learnt.
It’s easy to end up with some poorly taught material. If you carefully looked at the model which gave rise to the equation you are considering, there probably is a very tangible meaning to the figure everyone is ball parking.
40 is awfully close to 42
Quantitative finance really is a fascinating field, not because it will make you rich, but because you can dive much deeper into understand exactly what the market believes about the probability of different events.
Of course what the market believes doesn't have to be correct, but nonetheless very interesting to dive into.
I am certain the Swiss government will bail them out, direct democracy be damned.
Swiss bankers already lost a lot of customers to US banks, letting CS fail would have very bad consequence on Swiss economy long term
In addition, you have to take net present value of the settlement into account. Money compounds, it doesn't grow linearly. Let's say there's a 10% chance of a credit event in a year, a 0% chance today, and the chance grows linearly (27 bps/day). Even if the chance of a credit event grows linearly, and you hold the recovery rate steady, the net present value of the recovery amount grows as a function of e.
All that to say, I don't think what you are saying is correct.

Sometimes in a bankruptcy, bondholders take a "haircut" and agree to get less money back because the company simply can't pay them what they're owed.
