Review Questions

  • How did the housing market collapse contribute to the 2008 financial crisis?
    • The collapse of the housing market was central to the 2008 financial crisis. As home prices soared due to speculative buying and easy credit, many subprime mortgages were issued to borrowers who could not afford them. When housing prices began to fall, these borrowers defaulted on their loans en masse, causing significant losses for banks holding mortgage-backed securities. This resulted in a liquidity crisis that spread through the financial system, ultimately leading to bank failures and requiring government intervention.
  • Evaluate the role of mortgage-backed securities in exacerbating the 2008 financial crisis.
    • Mortgage-backed securities (MBS) were a key factor in deepening the 2008 financial crisis. Financial institutions pooled various mortgages into MBS and sold them to investors, spreading risk but also concealing underlying issues with subprime loans. When defaults increased, these securities lost value rapidly, triggering panic among investors. The interconnectivity of these securities meant that losses rippled through banks worldwide, leading to widespread financial instability and necessitating major government bailouts.
  • Assess how theories related to yield curves might explain investor behavior during the 2008 financial crisis.
    • During the 2008 financial crisis, yield curve theories suggested that investors were responding to changing economic conditions by seeking safer investments. Typically, a normal upward-sloping yield curve indicates economic growth; however, as uncertainty increased, many investors flocked to short-term government bonds despite their lower yields, causing an inversion in the yield curve. This behavior indicated a lack of confidence in long-term economic stability and highlighted how shifts in investor sentiment can significantly impact financial markets during crises.
