The Kiwibank & Japanese Model : Postal Banks to Serve Local Communities
Banking in post offices is not new.
Many countries, including Germany, France, Italy, Japan, and New Zealand,
have a long and successful history of it
and so does the United States.
If the USPS added banking,
it could use its own bank-generated credit to help relieve its debt problems.
According to German researcher Margrit Kennedy,
interest composes on average about 40% of the cost of all goods and services.
That suggests that eliminating interest could reduce the USPS debt by about 40%.
