The document compares the 2008 global financial crisis and the 2020 global crisis caused by the COVID-19 pandemic. It outlines the key causes and impacts of each crisis. The 2008 crisis was caused by falling housing prices, excessive risk-taking by banks and investors, and a lack of regulation of mortgage brokers and hedge funds. It resulted in major financial losses and a slowdown in the global economy. The 2020 crisis was triggered by the spread of the coronavirus, which caused countries to lock down and disrupted supply chains, trade, and daily life. It led to declines in stock markets, oil prices, manufacturing, and tourism. The document provides suggestions for preventing future crises, such as increased regulation and recognizing systemic risks earlier.
