The 2008 global financial crisis was caused by excessive risk taking and insufficient regulation of complex financial products like mortgage-backed securities in the US housing market. This caused falling home prices, bad debts, and a crisis of confidence that spread globally. The impact was a severe global recession, falling stock markets, reduced trade and job losses. The 2020 crisis was triggered by the COVID-19 pandemic which caused a global economic slowdown due to nationwide lockdowns and disruptions. Other factors included an oil price war between Russia and Saudi Arabia and stock market crashes. The impact has been high losses for many industries like aviation and tourism, as well as increased prices, slowed global trade, and a major worldwide recession.
