The subprime mortgage market crashed in 2007, causing many borrowers to struggle with payments and leading to a drop in housing prices. This led to calls for stricter laws against predatory lending and more oversight from regulators. Measures to combat predatory lending were put in place, causing concerns among lenders and investors. The issues in the subprime market spread to the jumbo mortgage market and secondary mortgage markets globally. Subprime mortgages are loans given to borrowers with poor credit histories, making them riskier for lenders.
