A $50 million margin call? I'll short Wall Street.

"The creditworthiness of financial institutions has deteriorated."

She answered quickly.

"Yes. But what happens after credit deteriorates?"

Isabella's thoughts began to extend along this line.

Credit deteriorates. Banks tighten lending. Businesses struggle to secure financing. Investment slows. Consumption contracts. Unemployment rises.

"The real economy is in recession," she said.

What happens after the real economy declines?

"Demand collapsed."

What will happen to crude oil demand after the collapse in demand?

Isabella's pupils contracted slightly.

She got it.

The declines in the S&P 500 and crude oil are not two separate events. They are driven by the same factor—the deepening credit crisis, which has spread to the real economy and triggered a comprehensive contraction in demand.

Oil prices are still at $140 because of the inertia of speculative capital. Hot money that fled the subprime market poured into commodities, a seemingly "safer" pool, pushing oil prices from $90 all the way up to $145.

But what is the true nature of this hot money?

It is fear.

It is fear-driven capital that has fled a collapsing market, has nowhere else to go, and is searching for the last piece of safe haven.

As the crisis deepens—as those funds begin to be redeemed, as the liquidity crunch spreads from the credit markets to every asset class—this hot money will also be forcibly withdrawn.

At that point, the last pillar supporting oil prices will break.

Isabella stared at the two lines of text on the whiteboard and remained silent for a few seconds.

"You're not shorting crude oil." Her voice became very soft, each word as if confirming something she had just realized but was still somewhat hesitant to believe.

"You're pricing in a recession."

Lu Ze did not deny it.

He simply put the marker back on the whiteboard shelf, walked back to his desk, and sat down.

"The deterioration of creditworthiness among financial institutions is the first layer," he said. "It has the highest certainty and the most obvious trend. CDS and XLF cover this layer."

"The spread of the crisis to the real economy is the second layer. It's less certain because the transmission takes time and the path is uncertain. But the direction is certain. The S&P 500 and crude oil cover this layer."

"The two layers are not sequential, but causal. The first layer is the cause, and the second layer is the effect. The first layer is already happening, and the second layer is in the process of happening."

Isabella stared at him for two seconds, then lowered her head and began taking notes rapidly on her tablet.

"What about the execution pace?" she asked.

How deep can you profit from put options on the S&P 500 and crude oil in the market?

This is an extremely practical issue, and one that she, as COO, must immediately figure out.

"As for the S&P 500," she said, pulling up the CBOE options chain data and glancing at it, "the deepest liquid forward puts on the exchange are around 1,100 points. Below that, there's almost no trading."

"What about the crude oil?"

"On the NYMEX December contract, the most liquid put option is around $110. Below that, market maker quotes are extremely thin, and the bid-ask spreads are too large to trade."

Lu Ze nodded: "Let's eat everything edible in the arena first."

"You know better than I what the advantages are."

He looked at Isabella.

"No risk to the other party," Isabella blurted out.

"Exchange liquidation, OCC guarantee. Regardless of who survives or fails in the future, as long as the exchange exists, our contracts will definitely be fulfilled. Moreover, liquidity is relatively good; you can sell them whenever you want."

"What are the drawbacks?"

"The deeper the out-of-the-money contract, the smaller the available trading volume. The scale and depth we need cannot be covered by the trading market. The portion of the S&P 500 that falls below 1100, and the portion of crude oil that falls below 1100, are basically unavailable on the market."

"Therefore, the off-field activities must begin simultaneously."

Lu Ze picked up the coffee cup on the table, found it was empty, and put it down.

"Make a small batch first. Under the guise of hedging."

Isabella looked up: "Hedge what?"

"We still have some remaining crude oil inventory in our inventory, right?"

"Yes. There are still a considerable number of call options being rolled over gradually."

"Use this batch of leftover stock as a reason."

Lu Ze said, "We told Goldman Sachs and Morgan Stanley that we are concerned about sharp fluctuations in oil prices in the short term and need to buy downside protection for our remaining long positions."

"Under this pretext, we commissioned each of them to create crude oil put options with premiums of tens of millions of dollars. The strike price was set between eighty and one hundred."

Isabella thought for a moment: "The scale and the rationale both make sense. A protective put of tens of millions is a perfectly reasonable risk management measure for the long positions we still hold on paper. They won't suspect anything."

"and,"

She added.

"The main purpose of these over-the-counter contracts isn't to make a lot of money. It's to open up the channel. So that when oil prices really start to fall rapidly later and we need to add over-the-counter options with deeper strike prices, we won't have to start negotiating from scratch."

Lu Ze looked at her and nodded.

That extremely faint trace of approval, which only she could detect, appeared once again.

"Finally, VIX," Lu Ze said.

"VIX is bullish."

Isabella had already written it on the tablet.

"Tail amplifier. When the market enters true panic mode, the VIX rises not linearly, but exponentially. Is 200 million enough?"

"That's enough. VIX is insurance within insurance. It doesn't need to be too big."

Isabella organized the final allocation plan on the tablet and handed it to Lu Ze for confirmation.

"Let's summarize."

"Added 400 million to CDS, 300 million to short XLF and a small number of individual stocks, 200 million to short S&P 500, more than 100 million to short crude oil, and more than 100 million to bullish on the VIX."

"A total of 1.1 billion," Isabella said. "Basically, all the profits that were in our pockets have been invested."

How much cash buffer should we keep?

Isabella calculated Farstar's current total cash pool—the oil profits already realized, plus the remaining amount from Bear Stearns, plus the cumulative income from daily mark-to-market settlements of CDS during this period.

"The pace of building positions won't be that fast, and with crude oil still rising, there's a considerable amount of open positions."

She said, "More than enough."

Lu Ze looked at the table and remained silent for two seconds.

"implement."

Isabella stood up and tucked the tablet under her arm.

She walked to the door, opened it, and then paused.

"Boss."

"Um."

"CDS, XLF, S&P 500, crude oil, and VIX. Five lines of analysis are being pursued simultaneously."

Her voice was extremely calm, but Lu Ze could hear something beneath that calmness—not fear, but a professional tension that comes with facing a huge gamble.

"From today onwards, Farstar Capital is no longer an energy fund that is bullish on oil."

Lu Ze leaned back in his chair, watching her profile as she stood at the doorway.

"Never," he said.

Isabella's lips twitched slightly—a subtle "I should have known" expression.

She went out and gently closed the door behind her.

In the trading room, the sound of keyboards clicking resumed.

Five fronts.

$1.2 billion in ammunition.

A machine for shorting the US economy has started to turn.
