The financial crisis, which is still ongoing, resulted largely from the boom and bust in home prices that preceded it for several years (home prices peaked in the United States in 2006). During the pre-crisis boom, homebuyers were encouraged to borrow heavily to finance undiversified investments in a single home, while governments provided guarantees to mortgage investors.
金融危机仍在进行中，这场危机的主要原因是此前几年中的房价起落（美国房价在2006年见顶）。在危机前的繁荣期，屋主被鼓励大量举债投资于单一的住房，而政府为按揭投资者提供了担保。在美国，这是通过对联邦住房局（Federal Housing Administration，FHA）和房利美、房地美等按揭机构的隐性担保实现的。
