Excellent question — and this is where the “notional vs. real exposure” distinction goes from academic to hair-raisingly real. Let’s unpack it without any sugar-coating.

==== Even if every underlying asset in the world went to zero overnight, the maximum losses wouldn’t be $730 trillion.  The real, system-wide exposure would likely cap out somewhere in the tens of trillions—still catastrophic, but nowhere near the notional figure. ====

Why? Because of netting, collateral, and counterparty chains.

==== a. Netting ====
Most big derivatives dealers offset positions with each other.
Example:
* JPM owes Citi $10 million on one swap.
* Citi owes JPM $9 million on another. Only $1 million moves. Across the system, this slashes theoretical exposure by 80–95%.

b. Collateral / Margin
Counterparties post collateral daily (cash, Treasuries, etc.) to cover mark-to-market losses.
So if assets plunge, collateral calls go out long before “everything” goes to zero.
The danger isn’t the price drop itself—it’s who can’t meet the margin call.

c. Counterparty risk & contagion
When one player defaults, the others eat losses and confidence evaporates.
That’s what happened in 2008: a small slice of the mortgage-derivative world detonated, but leverage and mistrust froze credit globally.

==== Let’s use the numbers from your screenshot. ====

If a shock wiped out 20 % of the underlying asset values, you might see:
* $4–6 trillion in mark-to-market losses,
* magnified by liquidity stress and defaults,
* enough to wipe out multiple major banks if governments didn’t intervene.

That’s about the scale of 2008 all over again—but not the end of civilization.

==== 1. Concentrated counterparties – a handful of megabanks handle 80%+ of derivatives. ====
# Opacity – most OTC contracts aren’t exchange-traded or transparent.
# Duration mismatch – short-term funding vs long-term exposure.
# “Wrong-way risk” – the hedge fails when you need it most (AIG’s downfall).

If multiple big players failed simultaneously and collateral chains broke, we could theoretically see $15–25 trillion in realized losses and temporary market seizure.
Governments would almost certainly print, guarantee, and backstop—because they’d have no other option.

==== |     |     |     | ====
| --- | --- | --- |
|     |     |     |
|     |     |     |
|     |     |     |
|     |     |     |

So, the “world blows up” number isn’t $730 trillion—it’s the much smaller (but still apocalyptic) slice that cascades through defaults, leverage, and panic. That’s why central banks monitor this market obsessively: they can’t afford to let the plumbing freeze again.

Would you like me to show a visual model of how a 10 % asset collapse propagates through derivative counterparty networks (so you can see where contagion amplifies vs. nets out)?
