But then again, low risk also means low returns, and these securities pull down the risk of the portfolio as well as the return on the portfolio.

At this time, Rothschild Bank's "gold stock" showed its advantages.

You know, Rothschild Bank's "gold stocks" are not only much more stable and less risky than US Treasury bonds, but also their dividend yields are much higher than those of US Treasury bonds, which is simply a godsend!

Therefore, Rothschild Bank's "gold stocks" were snapped up by traditional investment institutions such as the five major investment banks on Wall Street, which not only lowered the investment risk of these investment institutions, but also increased the return of the investment portfolio, which is simply too beautiful to want!

However, just now, Qiao Tianyu ordered the five major investment banks on Wall Street to sell off the $1.4 trillion Rothschild Bank shares they held.

As a result, in all the portfolios of the five major investment banks on Wall Street, the shares of Rothschild Bank, which is a risk stabilizer, are gone, and the rest are some high-risk securities, so the five major investment banks on Wall Street have exposed their risk positions to the greatest extent.

For them, this is simply a catastrophe, if the ill-intentioned people seize the opportunity to launch a strong attack, the five major investment banks on Wall Street will face the catastrophe, which is naturally unbearable pain for them!)

And now, under the erroneous leadership of Qiao Tianyu, all the shares of Rothschild Bank have been sold without any substantial return.

On the contrary, the five major investment banks on Wall Street have exposed their risk positions to the greatest extent and put the five major investment banks in an extremely dangerous situation, and the investment executives of the five major investment banks will naturally not do it!

The three investment executives led by Mr. Shamar were menacing, and they had to ask Qiao Tianyu for an explanation, but Qiao Tianyu was even more arrogant, and directly closed his eyes, putting on a posture that a dead pig was not afraid of boiling water.

And Rubin, Mr. Fuld, Sanchez and other Qiao Tianyu's "sworn friends" saw that the situation was not good, they were worried that Qiao Tianyu would suffer a loss, so they quickly got up and went to stop Mr. Shamar and them, while shouting Qiao Tianyu to quickly appease everyone's emotions.

However, today, Qiao Tianyu didn't know why, he couldn't hear the persuasion of others at all, he kept his eyes closed, gritted his teeth, and refused to speak, and the underground trading command hall was extremely chaotic for a while.

However, that Yamaki Kobayashi Lang was not an ordinary person, just when everyone on their side was celebrating the victory, the shrewd Yamaki Kobayashi Lang discovered the loophole "not surprisingly".

"That's right, now that the Rothschild Bank shares held by the five major investment banks on Wall Street have been sold out, and the five major investment banks have exposed huge risk positions, why not take advantage of this God-given opportunity to make a big deal and completely collapse the five major investment banks on Wall Street?"

And as long as the five major investment banks on Wall Street collapse, the last "living force" of Qiao Tianyu's side will be annihilated, and then Qiao Tianyu will only have the share of "surrendering the gun and not killing"!

Thinking of this, Yamaki Kobayashi Lang patted his head, God really helped me, just do it!

If all goes well, end this world offshore financial war in half an hour!

Having made up his mind, Yamaki Kobayashi immediately turned to look at his data analysis team behind him.

"Immediately analyze the investment assets held by the five major investment banks on Wall Street, and find out the biggest risk point exposed by the five major investment banks as soon as possible!"

"Yes!" Yamaki Kobayashi ordered, and the well-trained data analysis team immediately began to conduct a detailed analysis of all the portfolios held by the five major investment banks on Wall Street.

About ten minutes later, a detailed investment data analysis report was presented to Kobayashi Yamaki.

Taking the investment data analysis report, Yamaki Kobayashi couldn't wait to quickly glance through it, and then a strange smile suddenly swept across his face.

According to the investment data analysis report, in the past week, the five major investment banks on Wall Street have increased their short positions in the currencies of major developed countries in the international foreign exchange market without exception.

Goldman Sachs Group Inc. increased its short position in the British pound by about $600 billion;

Morgan Stanley increased its short position in the French franc by about $550 billion;

Merrill Lynch increased its short position in Deutsche Mark by about $470 billion;

Lehman Brothers increased its short position in the Canadian dollar by about $440 billion;

Bear Stearns increased its short position in the Italian lira, amounting to about $390 billion.

In other words, over the past week, the five major investment banks on Wall Street have increased their short positions in the currencies of major developed countries by about $2.45 trillion!

And the increased short positions in these currencies are also the biggest risk positions of the five major investment banks on Wall Street!

To explain simply, the so-called "short position" of a currency, that is, the opposite of the "long position" of the currency, is actually the meaning of shorting the country's currency.

In other words, if an investment institution determines that at some point in the future, a country's currency will depreciate significantly.

Then the investment institution can borrow the country's currency from other investment institutions in advance, and then sell it in the international foreign exchange market to obtain a profit from selling the currency.

At some point in the future, when the country's currency really depreciates sharply, then the investment institution can buy back the country's currency that was previously sold in the international foreign exchange market with less money and return it to other investment institutions.

The difference between the income from selling the currency at the beginning and the amount of money needed to buy back the currency later is the income from the investment institution's "short position" in the country's currency.

In other words, in the past week, the five major investment banks on Wall Street have held short positions in the currencies of the world's major developed countries, which means that the five major investment banks on Wall Street have determined that the currencies of these developed countries will depreciate sharply in the future.

Therefore, the five major investment banks on Wall Street acted in advance, borrowed so many currencies from developed countries and sold them in the international foreign exchange market, waiting for these currencies to depreciate in the future before buying them back.

The reason why the five major investment banks on Wall Street dared to hold short positions in so many currencies on such a large scale was because the five major investment banks also held a large number of Rothschild Bank shares as a hedge, cleverly hedging the risk of holding short positions in these currencies.

Let's take a simple chestnut to explain.

The biggest risk of the big five investment banks holding short positions in so many currencies is that the global economic situation continues to improve, and the currencies of these major developed countries will rise instead of falling, and the value of these currencies will continue to rise in the future.
