两房债券和其它public公司的债券区别：两房 Fannie Mae and Freddie Mac 是 public government sponsored enterprises (GSE),他们的债券是 implicitly guaranteed by the US government. This "implicit guarantee" means the government would not allow such important institutions to fail or default on debt. 结果两房的borrowing costs 就比所有的public companies 都要低。
两房债券金融界简称为 agency. 90年代末美国政府财政盈余，就不再发行并retire 30年 off-the-run USTreasury, 金融界就用两房30年债券as a proxy for the yield of 30-year US treasury to estimate the US yield curve.
