The 2008 global financial crisis was the worst economic meltdown since the Great Depression. It started as a housing market issue in the United States but soon became a global catastrophe that rocked the banks, governments, and households. Millions lost jobs, homes, and savings. To appreciate its full effect, we must examine how it evolved, the major incidents that saw it escalate, and its lessons.
The Roots of the Crisis
The crisis of 2008 was planted several years ago. Once the dot-com bubble burst, and with the 9/11 attacks to shake the economy, the Federal Reserve in the United States reduced interest rates significantly, as they stood at 6.5% in 2000, and only 1% in 2003. This was aimed at promoting borrowing and growth.
Cheap credit made mortgages more affordable, and homeownership rates rose. Lenders not only gave loans to the qualified borrowers but also to individuals with poor or no credit history, who are referred to as subprime borrowers. These loans were sold to Wall Street companies, which packaged them into highly complicated financial instruments known as mortgage-backed securities (MBS) and collateralised debt obligations (CDOs).
Credit rating agencies gave these products low-risk investments, even though they were loaded with risky loans. This was a stable system based on shaky foundations.
The Subprime Loan Boom and Its Consequences
The crisis was rooted in the subprime mortgage boom. In the early 2000s, it was simple to purchase a house. Many borrowers signed contracts that they did not understand with variable interest rates that gradually soared.
Wall Street banks had a significant role to play. They could multiply potential returns by investing 30 or even 40 times, increasing potential returns in the case of success and possible risks in the case of failure. After soaring housing prices in 2006, followed by a decline, millions of homeowners were indebted more than their assets were. Foreclosures and defaults began to increase.
Lenders such as New Century Financial, a subprime giant, filed for bankruptcy. Over 25 subprime lenders had fallen by 2007. What started as a housing issue was leaking over into the financial system.
The Domino Effect of International Finance
Panic started to sweep financial markets by mid-2007. In August, banks became scared to lend to each other as they were unsure who was holding the toxic mortgage assets. There was a credit crunch as the interbank lending system froze.

European banks did not escape. A large British lender, Northern Rock, was forced to turn to the Bank of England for support in an emergency. Swiss bank UBS reported billions of mortgage losses in the U.S. The shockwaves were cross-border since the world banks had heavily invested in the U.S. mortgage-backed securities.
In March 2008, Bear Stearns, among the oldest investment banks on Wall Street, failed.It was auctioned to JPMorgan Chase at a fraction of its worth. The crisis intensified in September when Lehman Brothers, a 158-year-old firm, became bankrupt in the biggest failure in the history of the U.S. Those events caused havoc throughout world markets, erasing trillions of values and creating a full-fledged financial panic.
The Post-war and State Intervention
At the end of 2008, the crisis had extended past banks to the real economy. Companies lay off workers, consumer buying was weakened, and trade was reduced to a crawl worldwide. In the United States, the unemployment rate is 10%, and millions of families have been foreclosed. Europe was experiencing a crisis, and Ireland, Greece, Spain, and Portugal were plunging deep into recessions.
Governments worldwide scrambled into damage control. In the United States, the Troubled Asset Relief Program (TARP) had a limit of up to 440 billion dollars to purchase toxic assets and infuse capital into failing banks. The Federal Reserve reduced the interest rate and gave emergency loans to financial institutions.
The anger of the people increased as people viewed banks getting bailed out and leaving the average people to suffer the crisis. Nevertheless, the intervention helped to avoid a total meltdown. By 2009, the markets had stabilised, and a lengthy recovery period commenced. The money the U.S government used in the bailouts was eventually recovered, and some of the investments even yielded profit.
Lessons of The Great Recession
The financial crisis that took place in 2008 taught a lot. It revealed the risks of taking too many risks, inadequate regulation, and a lack of awareness of financial engineering. The crisis revealed the interconnectedness of the global economic systems. Issues with mortgages in the United States would bring down European banks and lead to job losses in Asia.
To counter this, the U.S. enacted the Dodd-Frank Act in 2010, which sought to impose more regulation on banks, curb the culture of risky trading, and safeguard consumers against predatory lending. Though specific rules have been repealed, the act is still the most significant financial reform since the 1930s.

However, history does not forget that a crisis is not that exceptional. Financial bubbles have been witnessed from the Dutch Tulip Bubble of the 1630s to the dot-com bust in 2000. The point is to make sure that future bubbles will not become so large as to represent a danger to the whole world economy.
Conclusion
The 2008 financial crisis was not just a bank failure. It was an international affair that revealed significant lending, investing, and regulation defects. It demonstrated how fast financial optimism may translate into economic pessimism, and how the typical individual may be the bearer of the most significant cost.
Although the financial system has become stronger due to reforms, one cannot exclude the likelihood of crises in the future. With the changing markets and emerging risks, the experience of 2008 is still vivid: excessive speculation and poor regulation can bring even the most powerful economies to their knees.
