The document discusses the global financial crisis of 2008. It began in the US due to risky subprime mortgages and the securitization and trading of mortgage-backed securities.

This caused recessions around the world as global trade declined. While Pakistan's financial sector was not directly impacted, its economy still suffered effects through slowing global demand and reduced foreign investment.
