As Credit Suisse is aware, Counterparty credit risk is so complicated, that almost all the formulas in the CRR had to be corrected two years later !

A thread!
Ooops we forgot a floor in the duration calculation (btw this formula is still horribly wrong)
Who’s the bloody intern who forgot the long-term bonds in the notional calculations!?
Seriously, no one told you that a number inside a square root has better be positive? (I mean CCR is complex, but not in *that* sense)
I can’t believe you made the same error TWICE!
When you say it out loud, SF sounds so much nicer than SK
You can’t sum on a null set, dude.
Rule number 1 of mathematical logic : if you open a parenthesis, you have to close it & vice versa. You might not seen it, but the computer will.
I can’t believe they took the wrong hedging set for non-electrical commodities. Rookie error.
Read it 23 times and see if you can find the error.
Yeah, I always make the same mistake when I price a bond. 1%, one Basis point, what’s the difference anyway. It’s only money.
Confusing notional and market value for a Jump to default… this will not end well.
Do you need an aspirin ?
Banking regulations are so complex that, after taking three years to draft a regulation, they have to publish a corrigendum two years after, because it was filled with errors.

I hope you feel reinsured.

Why is Deutsche stock hammered today?

An old theme is coming back to haunt them: Basel 4!

Quick thread. Image
After almost 10y of discussion the package was finally enacted with full implementation in 2033.

Everyone felt, after many EBA reports & banks' disclosures, that impact would be mild.

But for first time banks are publishing capital ratios w/ the new rules and for DB it's ugly
How does it work? Banks are still allowed to use internal models, but the RWA (in 2030/2033) must be at least 72.5% of the standard (non internal models) RWA. ("output floors") and for DB that's a 33% increase!
CET1r would go from 13.8% to 10.35%! Ouch! Image

Why is the latest EC proposal on securitization a big deal for banks and how does it change the SRT market?

A slightly geeky thread - with some backround on the SRT market if you're not aware of this important market.
First what’s a SRT?

Following secular finance practice of reinventing the wheel but changing its name, the new trendy capital optimization transactions are “significant risk transfers”, but they’re just good old securitizations (invented in the 1860s 😊.)

(cash or synthetic) Image
The reason they’re now called SRT is a regulatory one.

The 2013 CRR (Art 244/245) allowed banks to get capital relief under some conditions, essentially that “significant risk” was transferred to someone else.

Are you readyyyyy for LDI take 2?

Hear me out. Something’s brewing in the UK Gilt market.

As the chart above shows, the cash swap spread has moved significantly & one-way recently.

Spread to swap is now 50bps.

But EU & UK insurers book their liabilities at NPV using swap curves, not UKT curves.

Still with me ?
This means that Gilts have become an excellent investment for life insurers.

The CSM for new business is going down (but still positive) but the charge for credit is now 0 so ROE increase significantly.

So far so good.

Bloomberg has some nice charts on the tariffs’ impacts.

The first one argues that tariffs on China are coming globally: too many countries will see a spike of imports from China & that's not sustainable. Image
The second shows GDP impacts, taking into account direct effects + indirect via trade partners (using a WTO macro model, so, you know...)

SE Asia impact is massive, -1% for EU, -1.3% Japan and -2.5% Korea. Mexico bonanza. Image
Some details on who’s going to stop which exports – very interesting split (especially if you try to model loan losses 😊). Overall 30% drop in US imports of goods (with retaliation modelled as 50% of US). China is -85%, Vietnam -75%, Taiwan, Japan, Korea Thailand -50%, EU -40%. Image

A week ago the Swiss gvt bravely decided to leave the decision on UBS capital requirement to Parliament.

I’m not sure that was such a great idea – as the recent proposal of the Swiss Social-Democratic Party shows.

If implemented, it would be a massive game changer. A thread.
First, a reminder: the SDP is not a fringe party, they’re #2 in the National council (41/200) & #3 in Council of States (9/46) & they’re also not particularly extreme (I mean, Swiss rarely are.)

But their proposals for UBS are a bit wild.

Let’s unpack.
1) A new leverage ratio surcharge of 3% for assets >300bn$ - in practice it means 40bn$ more capital required (out of approx 85bn of equity).

Ouch.

And having the biggest req on a non-risk adjusted basis is not exactly a very safe approach imho

Tomorrow is the end of the grace period for fentanyl-related tariffs (Canada Mexico), China ones r supposed to start on March 12. Time to look at some numbers. So far Trump has enacted 10% “fentanyl” tariffs on Chinese goods, enacted and cancelled 25% on Columbia and threatened :
Canada, Mexico (25% goods + 10% Canadian energy), China (+10% addtl), 25% steel & aluminium worldwide, “fees” for Chinese ships/freight operators, “reciprocal tariffs” (whatever that means) for all nations + 25% autos pharma & lumber, + unknown % on copper.
We’ll know more after the report on ‘America First Trade Policy’ on April 1st, especially on "reciprocal ones", but here are few thoughts from a great Autonomous report on this.

Some historical perspective: maybe raising tariffs in the early 1920 wasn’t a great idea? Image
