📉 Stock Market Crash of 1929 and the Great Depression

This paragraph discusses the historical context and the events leading up to the stock market crash on Black Thursday, October 24, 1929. It clarifies misconceptions about the crash, explaining that it did not cause the Great Depression but rather signaled its beginning. The economic boom of the 1920s, marked by urbanization, technological advancements, and increased wages, set the stage for a period of mass consumption and cultural prosperity. However, this expansion masked underlying issues that would lead to the subsequent economic collapse. The paragraph also provides an explanation of how stock markets function, including the basics of trading shares and the impact of investor behavior on stock prices. It introduces the concept of speculative bubbles and how their burst can lead to market crashes, using the metaphor of a beauty contest to illustrate the irrational exuberance of investors.

🌾 Economic Overheating and the Agricultural Sector's Role in the 1929 Crash

The second paragraph delves into the specifics of the economic conditions prior to the 1929 stock market crash. It highlights how the U.S. economy was booming, with production increasing by 50% from 1921 to 1929, while stock values on Wall Street soared by an unprecedented 3,100%, indicating a severe disconnect between stock values and actual economic performance. The paragraph also points out that certain industries, such as automobiles and real estate, had begun to slow down significantly by 1925, but this was overlooked due to the widespread belief in continued economic prosperity. The role of the agricultural sector is emphasized, as overproduction and debt led to a drop in prices, further destabilizing the economy. The paragraph concludes by explaining how the realization of this overestimation of the real economy led to a panic selling of stocks, which cascaded into a global financial crisis, and how the subsequent loss of trust in banks exacerbated the situation, leading to the Great Depression. It also draws a parallel between the events of 1929 and contemporary economic issues, as well as the 2008 financial crisis, where the relationship between finance and the real economy was reversed.

Keywords

💡Black Thursday

Black Thursday, also known as the Thursday after the stock market crash of 1929, marked the beginning of the Great Depression. It is significant in the video as it represents the starting point of a major economic downturn. The script refers to this event to draw parallels with the stock market crash of 2008 and to discuss the factors leading to the collapse of the U.S. economy.

💡Great Depression

The Great Depression was a severe worldwide economic depression that took place mostly during the 1930s, beginning in the United States. In the video, it is the historical context used to discuss the aftermath of the stock market crash and the economic conditions that led to widespread unemployment and poverty. It is contrasted with the economic boom of the 1920s and the subsequent crash.

💡Stock market crash

A stock market crash is a sudden dramatic decline in stock prices across a significant cross-section of a stock market. In the video, the crash of 1929 is the central event that led to the Great Depression. The script explains how the crash was a result of speculative bubble and overvaluation of stocks, which eventually burst, causing a panic sell-off.

💡Speculative bubble

A speculative bubble occurs when the price of an asset increases rapidly, far exceeding its intrinsic value, often driven by speculation or investor exuberance. The video describes the 1920s stock market as a speculative bubble, where stock prices were inflated far beyond the actual value of the companies they represented, leading to the eventual crash.

💡Economic boom

An economic boom is a period of rapid economic growth and prosperity, often characterized by increased consumer spending and investment. The video contrasts the economic boom of the 1920s, known as the 'Roaring Twenties,' with the subsequent depression, highlighting the stark shift from prosperity to economic hardship.

💡Dividends

Dividends are payments made by a corporation to its shareholders, usually as a distribution of profits. In the video, dividends are mentioned as one of the benefits of owning shares, but the focus is on the speculative nature of the stock market where investors were more concerned with the potential for capital gains rather than dividends.

💡Shareholders

Shareholders are the owners of shares in a company and are entitled to a share in its profits. The video discusses shareholders' behavior leading up to the 1929 crash, emphasizing how their speculative actions contributed to the overvaluation of stocks and the eventual market collapse.

💡Credit

Credit refers to the practice of lending money, which businesses and individuals can use to finance their activities. In the video, the easy availability of credit is highlighted as a factor that fueled the speculative bubble, as banks were too lenient in lending money for stock speculation rather than productive investments.

💡Speculation

Speculation is the act of investing in assets with the hope of making a profit from changes in their prices, rather than from their intrinsic value or income. The video explains how speculation in the stock market led to inflated stock prices and the creation of a bubble that eventually burst, causing the crash.

💡Keynes' beauty contest metaphor

The Keynes' beauty contest metaphor is a concept introduced by economist John Maynard Keynes to explain investor behavior in a stock market. In the video, this metaphor is used to illustrate how investors in the 1929 market did not buy stocks based on their intrinsic value but rather on which stocks they thought other investors would buy, leading to irrational exuberance and market instability.

💡Agricultural sector

The agricultural sector refers to the part of the economy that produces food, fiber, and other plant and animal products using the natural resources of land and water. The video mentions the agricultural sector as one of the areas that contributed to the crash, as overproduction and falling prices led to financial difficulties for farmers, which in turn affected the broader economy.

Highlights

On March 9, 2020, global stock markets experienced their biggest drop since 2008, reminiscent of the 1930s crisis which began with the Wall Street crash on Thursday, October 24, 1929, known as Black Thursday.

Contrary to popular belief, Black Thursday did not cause the crisis itself but rather announced the crisis of the 1930s, which was a result of economic developments in the 1920s.

The 1920s were characterized by economic prosperity, urbanization, modernization, and a significant increase in wages, leading to the beginning of mass consumption.

Cultural phenomena like jazz and Hollywood's global film market contributed to the optimism of the era.

Despite the outward prosperity, several underlying factors were leading to the upcoming crash and the crisis of the following decade.

An explanation of how stock markets work, including the financing of companies through credit and the issuance of shares.

A share represents a percentage of ownership in a company, allowing shareholders to receive dividends and sell their shares on the financial market.

The theoretical function of share prices is to reflect a company's performance, but in practice, they often reflect investor speculation rather than actual value.

John Maynard Keynes' metaphor of the beauty contest is used to explain the speculative nature of stock market investments.

The 1929 stock market crash, remembered as Black Thursday, was not the worst day but marked the beginning of a series of worse days.

The crash was a result of overenthusiasm due to the booming economy of the 1920s, which led to excessive credit and speculation.

Banks were lending more for speculation than for purchasing homes or starting businesses, contributing to the bubble.

Between 1921 and 1929, U.S. production increased by 50%, but Wall Street stock values rose by 3,100%, indicating a severe overestimation of the economy.

The automobile and real estate industries began to slow down significantly from 1925, but this was overlooked due to the prevailing optimism.

Agriculture also played a role in the crash, as post-World War I production increases led to a surplus and low prices, impacting farmers.

The realization of the overestimation of the real economy led to a panic, causing a domino effect of selling shares and a market collapse.

The financial panic led to a loss of trust in banks, resulting in widespread withdrawals and a deepening of the crisis.

The 1929 financial crisis was a significant event, but it was not the cause of the Great Depression, which was a symptom of the beginning of the crisis.

The situation is somewhat similar to today's economy, where the real economy is struggling, and finance takes a significant hit.

The video differentiates the 1929 crisis from the 2008 crisis, where finance impacted the real economy.

play01:53

beaucoup d'actionnaires qui veulent

play01:54

acheter une action par exemple celle de

play01:56

volkswagen

play01:56

le cours de l'action de volkswagen

play01:58

augmente mais quand au contraire

play01:59

beaucoup d'actionnaires veut la vendre

play02:01

le cours de l'action baisse donc si

play02:03

volkswagen fait de la merde par exemple

play02:05

si on révèle dans les médias qu'ils ont

play02:06

totalement frauder dans leurs mesures

play02:08

d'émissions de gaz polluants

play02:09

volkswagen aura moins de clients parce

play02:11

que leur réputation sera endommagés les

play02:13

actionnaires vont considérer que

play02:15

volkswagen va faire des pertes et que

play02:16

l'action ne va rien leur apporter donc

play02:18

ils vont essayer de la vendre en gros le

play02:20

cours d'une action est censée révéler la

play02:22

performance d'une entreprise parce qu'on

play02:23

se dit que les actionnaires sont

play02:25

rationnels et qui savent parfaitement

play02:26

quelle entreprise se porte bien et là

play02:28

qu'elle fait de la merde en offrant et

play02:30

en demandant une action ils sont

play02:31

capables de faire émerger un prix qui

play02:33

révèle la performance réelle de

play02:34

l'entreprise

play02:35

voilà ça c'est en théorie mais dans la

play02:38

pratique c'est totalement l'inversé qui

play02:39

se passe et on en vient à l'explication

play02:41

de l'effondrement de la bourse à partir

play02:43

du 24 octobre 1929 en théorie comme je

play02:46

viens de vous expliquer les actionnaires

play02:47

devraient acheter les actions des

play02:49

entreprises qui se portent bien et

play02:51

vendre celles dont les entreprises font

play02:53

n'importe quoi en réalité les

play02:54

actionnaires vont plutôt acheter les

play02:56

actions qu'ils pensent qu'elles vont

play02:58

attirer le plus d'acheteurs

play02:59

si t'as rien compris t'inquiète pas je

play03:01

vais t'expliquer l'économiste john

play03:02

maynard keynes utilise la métaphore du

play03:04

concours de beauté pour expliquer ce

play03:06

phénomène

play03:06

en gros imagine que tu fais partie du

play03:08

jury d'un concours de beauté et que tu

play03:09

dois voter pour le candidat qui d'après

play03:11

toi est le plus beau mais comme tu es

play03:13

intelligent tu vas plutôt voter pour

play03:14

celui

play03:15

lequel tu penses que le plus de jury

play03:17

vont voter pour la bourse c'est

play03:19

exactement la même chose quand tu es un

play03:21

actionnaire tu t'en fous citons d'action

play03:22

a vraiment de la valeur ou pas

play03:23

l'important c'est que les gens pensent

play03:25

qu'elle a de la valeur parce que c'est à

play03:27

ce moment là qu'ils vont essayer de

play03:28

l'acheter c'est le principe de la

play03:30

spéculation quand tu vends là que tu

play03:31

achète des actions en fonction des

play03:33

variations de leurs cours sur le marché

play03:34

ce qui fait qu'on se retrouve avec plein

play03:36

d'action dont la valeur n'a rien à voir

play03:38

avec la performance réelle de

play03:39

l'entreprise

play03:40

c'est ce qu'on appelle une bulle

play03:41

spéculative et quand cette bulle explose

play03:44

c'est à dire qu'on se rend compte de ce

play03:45

décalage entre la valeur de l'action et

play03:47

la performance de l'entreprise

play03:49

c'est la panique tout le monde cherche à

play03:51

vendre ses actions d'un seul coup les

play03:53

prix chutent brutalement et tout le

play03:55

marché s'effondre par un effet domino

play03:56

voilà c'est un peu compliqué mais

play03:57

j'espère que tu as compris

play03:58

en tout cas si tu as compris ça tombe

play04:00

bien parce que c'est exactement ce qui

play04:01

s'est passé le jeudi noir en 1929

play04:04

on se souvient surtout de jeudi parce

play04:05

que c'est là où tout a commencé mais en

play04:07

réalité c'était pas la pire journée

play04:08

parce que les jours qui ont suivi

play04:09

étaient bien pires plus globalement ce

play04:12

qui s'est passé c'est que tout le monde

play04:13

était beaucoup trop enthousiaste à cause

play04:15

de l'économie qui allait beaucoup trop

play04:17

bien oui tu as bien entendu l'économie

play04:20

des années 20 aux états unis allaient

play04:21

beaucoup trop bien c'est possible ça

play04:23

allait tellement bien qu'on a oublié

play04:25

pourquoi ça allait bien et si on y avait

play04:27

réfléchi on se serait rendu compte qu'il

play04:28

y avait quelque chose qui n'allait pas

play04:29

si les fermiers produisait plus avec un

play04:31

équipement plus moderne c'est parce

play04:33

qu'il s'était endetté et que les banques

play04:34

à accorder beaucoup trop de crédit trop

play04:36

facilement si la finance allait bien et

play04:38

que ça continue à monter au fur et à

play04:40

mesure c'est aussi parce que les banques

play04:41

traiter beaucoup trop facilement aux

play04:43

actionnaires principalement pour

play04:44

spéculer quelques mois avant le krach on

play04:46

était arrivé à un point où les banques

play04:48

prêtaient beaucoup plus d'argent pour

play04:49

spéculer que pour acheter des maisons ou

play04:51

lancer sa propre entreprise

play04:53

alors que la spéculation ça n'apporte

play04:54

absolument rien à l'économie réelle ça

play04:56

ne permet pas aux entreprises de se

play04:58

développer au contraire les banques

play04:59

prêtaient trop facilement parce qu'on se

play05:01

disait que tout allait bien encore une

play05:02

fois l'économie allait beaucoup trop

play05:04

bien et ça c'est un système qui

play05:06

fonctionne sans problème jusqu'au moment

play05:07

où la bulle éclate et qu'on se rend

play05:09

compte qu'on a surestimé les

play05:10

performances de l'économie réelle à

play05:12

cause de la finance concrètement de 1921

play05:14

et 1929 donc juste avant le krach la

play05:17

production aux etats-unis avaient

play05:18

augmenté de 50% ce qui était pas mal

play05:20

sauf que la valeur des actions à wall

play05:22

street avait grimpé de 3

play05:24

100% six fois plus on avait surestimé

play05:26

l'économie six fois ajoutons à ça que

play05:29

depuis 1925 l'industrie de l'automobile

play05:31

est le secteur de l'immobilier avaient

play05:33

commencé à ralentir considérablement et

play05:35

ça personne ne l'avait vu venir parce

play05:37

que tout le monde pouvait acheter des

play05:38

voitures est tout le monde d'accéder à

play05:40

la propriété donc on se disait que tout

play05:42

allait bien et qu'il n'y avait aucune

play05:43

raison de s'inquiéter un autre élément

play05:44

qui a provoqué le krach c'est

play05:46

l'agriculture parce que pendant la

play05:47

première guerre mondiale l'agriculture

play05:49

avait connu une forte expansion et dans

play05:51

les années 20 la production a fortement

play05:53

augmenté à cause de ça pour écouler

play05:55

leurs stocks les entreprises agricoles

play05:56

étaient obligés de vendre à des prix

play05:58

très bas pour les consommateurs c'était

play06:00

très bien pour les agriculteurs ça

play06:02

l'était un peu moins

play06:02

bref il y avait énormément de décalage

play06:04

et quand les actionnaires à wall street

play06:06

s'en sont rendu compte tout le monde a

play06:07

essayé de vendre ses actions d'un coup

play06:09

sauf que pendant un moment il y avait

play06:11

plus d'acheteurs donc les prix se sont

play06:12

écroulés et par effet domino ça s'est

play06:14

propagé au pays entier

play06:16

ensuite ça s'est propagé au monde quand

play06:18

on s'est rendu compte à quel point on

play06:19

avait surestimé l'économie réelle

play06:20

c'était la panique

play06:21

et ça a empiré la situation parce que

play06:23

quand on se rend compte qu'il ya une

play06:24

panique au niveau de la finance on ne

play06:26

fait plus confiance aux banques donc

play06:27

tout le monde va retirer son argent

play06:29

manque de bol bas les banques n'avaient

play06:31

plus rien ils avaient tous prêtés aux

play06:32

actionnaires pour spéculer en pensant

play06:34

qu'ils allaient être remboursés

play06:35

facilement parce que l'économie allait

play06:37

trop bien je sais que c'est très contre

play06:39

intuitif mais je le répète encore une

play06:40

fois oui l'économie peut aller trop bien

play06:43

ce qui fait que on ignore volontairement

play06:45

ou pas les raisons qui font cette

play06:47

expansion et cette croissance

play06:48

donc voilà ça c'était la crise

play06:49

financière de 1929 c'était la merde

play06:52

surtout si tu étais un investisseur ou

play06:53

un agriculteur mais ce n'est pas ce qui

play06:55

a causé la crise de 1930 c'était un des

play06:58

symptômes du début de la crise

play06:59

finalement c'est assez similaire à ce

play07:01

qu'on voit aujourd'hui l'économie réelle

play07:02

va mal et du coup la finance en prend un

play07:04

sacré coup il ne faut pas confondre avec

play07:06

la crise de 2008 où là c'était l'inversé

play07:08

tu es la finance qui avaient impacté

play07:09

l'économie réelle

play07:10

je reviendrai sur la crise des années

play07:11

1930 dans une future vidéo en tout cas

play07:13
