历史泡沫与崩盘前的共同警告信号

Market bubbles and their crashes always begin with an opportunity. Some of history's worst investments began with ideas that changed the world. Railways transform transport. The internet built during the com bubble transformed well pretty much everything. So real opportunity attracts money and we get rising prices. Rising prices attract speculation. Speculation attracts leverage. And eventually when everyone becomes so convinced that the prices will only rise, the whole thing starts falling apart right in front of their eyes.

So, in this video, we're going to take a look at some of the biggest bubbles and financial crashes in history. Explain how some of the smartest people in the world got caught up in them and the warning signs they all shared so you can spot the next financial bubble, possibly even this one, before it's too late. My name is DC and you're watching the Coin Bureau. Let's start by traveling back in time to the 1600s and look at one of the earliest well-known bubbles in the Dutch Republic.

Back then, the must-h have luxury item wasn't a sports car or a designer watch. It was a flower. Tulips arrived in Europe from the Ottoman Empire and rapidly became symbols of wealth and sophistication. Some rare varieties of the flower had unusual streaks and patterns which were considered even more valuable. So, prices started rising quickly because supplying was limited and demand was growing. And boom, the beautiful flower caught the eye of investors.

Now, of course, they never cared about gardening. They were focused on one thing and one thing alone, making money. Thus, the tulip mania was born and finance discovered its favorite hobby. Turning something simple into something nobody can explain at dinner. It started with traders buying and selling contracts for bulbs that were still underground. And people started effectively speculating on flowers they had not seen and in some cases would never personally receive.

To be fair, it's not like it destroyed the entire Dutch economy. People weren't trading their homes for one bulb. When prices reached absurd levels, the market ran out of greater fools and then buyers suddenly disappeared. A lot of crazy stories circulate about the tulip mania and most of them are exaggerated for a dramatic effect, but there's no mistaking that people went crazy for nothing more than a flower. Now, let's head west and fast forward to 1720.

The South Sea Company helped manage government debt and held trading privileges which were connected to South America. This was a loaded operation with political backing, royal connections, and a story which involves access to distant markets supposedly filled with riches. But the actual trading prospects didn't turn out to be as impressive as the promotional story suggested. Nevertheless, the share price still increased because official support made the company look safe, and its overseas ambitions made it sound enormously profitable.

At around the same time back in Europe, France was going through something similar with the Mississippi Company. John Law created a financial system which involved paper money, government debt, and shares tied to grand promises about France's territories in North America. Rising prices seemed to prove the scheme was working as more money entered circulation and share prices just kept going up. And eventually, confidence collapsed once the investors questioned whether the profits that were promised could ever justify those prices.

This brought the whole scheme crashing. Now, despite relying on these different stories, tulips, the South Sea Company, and the Mississippi Company had ingredients that were remarkably similar. Scarcity, incredible promises, respected backers, and rising prices that made skepticism look foolish. And that is what makes bubbles dangerous. From the outside, they often look absurd, but from the inside, they feel like rare opportunities that everyone else has finally learned to recognize.

A century after the South Sea bubble, Britain encountered an opportunity that was far more tangible. Steam railways. Railways were revolutionary around the mid 19th century. They could move people and goods faster than horses or canels. It could connect industrial cities and completely reshape trade. The network in Britain was rapidly expanded after the Liverpool and Manchester Railway proved that passenger travel could be commercially viable.

So by the early 1840s, established railway companies were producing respectable returns and naturally investors concluded that if some railways were successful, then almost any railway proposal must be worth funding. So the parliament authorized thousands of miles of railway tracks, mostly on the basis of extremely optimistic projections. And now, as we all know, constructing a railway track isn't cheap. It requires an enormous enormous amount of iron, labor, land, and capital.

So initially investors had to pay only a part of the cost of their shares. But little did they know railway companies could later demand the rest of the cost as well. And once those calls arrived, many investors realized that enthusiasm was much cheaper than actually building a railway track. Mounting construction costs and tighter credit brought this boom to an end by 1847. Railway shares fell heavily after many proposed lines were abandoned and weaker companies failed to deliver.

Even routes that were complete sometimes struggled because several companies built competing lines to serve the same journeys. But there's a plot twist. Britain's economy transformed for the better because during all this chaos, they now had a railway network. Even though many of the investments failed, the technology ultimately succeeded. You see, there is no shortage of strange bubbles, spectacular crashes, and expensive lessons to explore.

Okay, let's move on from the railway mania and drive into the 20th century. By the late 1920s, the United States was enjoying what appeared to be a new age of permanent prosperity. The stock market seemed to offer ordinary Americans a front row seat to the future. Corporate profits were rising and consumer credit was expanding. But the excitement turned to greed real fast and blurred the vision of most investors who thought that share prices would rise forever.

A major source of fuel during this time was margin borrowing, which means that instead of paying the full price for shares, investors could put down a relatively small amount and borrow the rest from a broker. When prices rose, this multiplied the profits. When prices fell, it performed the same trick, but in reverse, which was considerably less fun. So, rising prices encouraged more borrowing and more borrowed money pushed prices even higher.

And it all became a vicious cycle in which the market's success appeared to justify the behavior which made it increasingly fragile. But then came Black Thursday, the day when confidence broke. On the 24th October 1929, a wave of selling overwhelmed the market. Bankers briefly restored calm by organizing large share purchases, but this relief did not last long. The following week, prices collapsed again because investors rushed to sell in large numbers and trading systems struggled to keep up. and leverage made everything even worse.

As share prices fell, brokers demanded additional money from investors whose collateral started to disappear. Those who could not pay were simply forced to sell. This was like a domino effect that pushed prices down further and triggered more marg
