Problem: The bursting of the U.S. (United States) housing bubble, which peaked in 2004, caused the values of securities tied to U.S. real estate pricing to plummet, damaging financial institutions globally. The financial crisis was triggered by a complex interplay of policies that encouraged home ownership, providing easier access to loans for subprime borrowers, overvaluation of bundled subprime mortgages based on the theory that housing prices would continue to escalate, questionable trading practices on behalf of both buyers and sellers, compensation structures that prioritize short-term deal flow over long-term value creation, and a lack of adequate capital holdings from banks and insurance companies to back the financial commitments they were making. Questions regarding bank solvency, declines in credit availability and damaged investor confidence had an impact on global stock markets, where securities suffered large losses during 2008 and early 2009. Economies worldwide slowed during this period, as credit tightened and international trade declined. Governments and central banks responded with unprecedented fiscal stimulus, monetary policy expansion and institutional bailouts. In the U.S., Congress passed the American Recovery and Reinvestment Act of 2009.
One of the causes of the financial crisis was easier access to loans by this type borrower?
The answer is the following: subprime
