Financing your home, financing your country.

Interest is paid out on 10-year Treasuries at six-month intervals. The 10-year Treasury has a ten-year maturity.
When an investor purchases a 10-year Treasury, in exchange for receiving interest, that investor is making a de-facto “loan” to the United States government. The government then uses those funds to finance itself.

In essence, when you purchase your home, when you obtain your 30-year mortgage, you are financing not only your home. You are also financing the United States government. Through mortgage payments you make. Each and every month.
