README (SKILL.md)

Fannie Mae

历史时间线

  • 1938年：罗斯福新政时期创立，旨在扩大住房贷款流动性
  • 1968年：转为私营公司，政府支持但市场化运营
  • 1970年： Freddie Mac成立作为竞争对手
  • 2008年：金融危机中被联邦政府接管（conservatorship）
  • 2008-2024年：在FHFA监管下运营，利润上缴财政部
  • 2024年：讨论释放保守管理状态（release from conservatorship）

商业模式

不直接发放贷款，而是从贷款机构购买抵押贷款，将其证券化为MBS（抵押贷款支持证券）出售给投资者，从而为住房市场提供流动性。赚取担保费和利差。截至2024年，担保或持有的抵押贷款超过$5万亿。

护城河分析

政府隐性担保（虽然法律上是私企，但市场认为政府会兜底），在美国住房金融体系中不可替代的基础设施角色，与Freddie Mac形成的双寡头市场结构。

关键数据

1938年创立，担保/持有超$5万亿抵押贷款，2008年被政府接管至今

有趣事实

房利美的全称是'Federal National Mortgage Association'——它是罗斯福新政的产物，目的是让普通美国人在大萧条后能更容易获得住房贷款。讽刺的是，它在2008年金融危机中差点毁了美国住房市场。
