How Does Globalization Accelerate the Spread of Financial Crises?

You can imagine globalization as a vast, interconnected transportation network, linking every "city" (country) around the world. This network brings immense convenience, allowing goods, capital, and information to flow at unprecedented speeds. But the flip side of the coin is that when a "city" experiences a crisis, like a fire, the blaze can quickly spread to other places through this network.

Specifically, there are several main "channels" through which this happens:

1. The "Highway" of Capital – Financial Market Integration

This is the fastest and most direct channel. In the era of globalization, your money can move from a bank account in China to buy stocks in the US in seconds. Similarly, a US pension fund might have bought bonds in an Asian country, or a European bank might have provided a large loan to a project in South America.

• How does it spread?
  • Suppose the US stock market crashes due to a bubble (like the housing bubble in 2008). Then, all institutions and individuals worldwide who invested in the US stock market (including you and me) will see their assets evaporate instantly.
  • To save themselves, these institutions that lost money might be forced to sell off assets they hold in other countries (e.g., stocks in Brazil, bonds in Europe), triggering a chain reaction of sell-offs in those markets.
  • Thus, a crisis in one country quickly infects global investors through this dense capital network, leading to a situation where "everyone loses."

2. The "Domino Effect" of Trade – Global Supply Chains

Nowadays, it's rare for a product to be manufactured from start to finish in a single country. A mobile phone might have chips from the US, a screen from Korea, a battery from China, and finally be assembled in Vietnam. This is the global supply chain.

• How does it spread?
  • If a large economy (like the US or the EU) experiences a crisis, people's purchasing power will sharply decline; simply put, they "stop buying things."
  • Then, companies and countries that rely on exports to these nations will suffer. For example, German cars won't sell, Vietnamese factories won't receive orders, and Brazilian iron ore will be unwanted.
  • The result is that factories in these countries close down, workers lose their jobs, and their economies also fall into distress. A "cold" in a major consumer nation quickly causes all global suppliers to "catch a fever."

3. The "Interlocking Chain" Among Banks – Interconnected Financial Institutions

Large global banks have very close business dealings. Today I lend you money, tomorrow you owe me money; everyone is both a creditor and a debtor, with complex intertwined relationships.

• How does it spread?
  • In 2008, when Lehman Brothers in the US collapsed, financial institutions worldwide were terrified. Everyone wondered: "Will the money I lent to Lehman be unrecoverable?" and "Will companies that owe money to Lehman now also collapse?"
  • This panic and distrust led banks to stop lending to each other. The "blood" of the entire financial system – capital – instantly froze.
  • This "credit crunch" is fatal. Businesses can't get loans to operate, individuals can't get loans to consume, and economic activity quickly grinds to a halt. The fall of one major bank is like pushing over the first domino.

4. The "Amplifier" of Panic – Rapid Spread of Information and Confidence

In the internet age, information (whether true or rumor) spreads at light speed. Investor sentiment, especially panic, can easily be amplified.

• How does it spread?
  • When signs of a crisis appear in one country, global investors immediately learn about it through news and social media. Driven by self-preservation instincts, they form a "herd mentality," scrambling to withdraw funds from markets they perceive as "risky."
  • This large-scale capital flight can itself create a crisis. A country's economic fundamentals might be sound, but due to collective investor panic and sell-offs, its currency depreciates and its stock market plummets, effectively being "scared" into a financial crisis.

In summary:

Globalization is like a double-edged sword. It has greatly promoted economic prosperity and efficiency, but it has also tied all countries together on a "ship of shared destiny." If a leak appears in one corner, and it's not plugged in time, it will quickly endanger the safety of the entire ship. The 2008 financial tsunami is the most typical example; it started with the "small crack" of the US subprime mortgage crisis and eventually evolved into a massive storm sweeping across the globe through the channels mentioned above.
