Financial inclusion is a topic of increasing interest on the international policy agenda. Last week the Universal Postal Union (UPU) hosted the 2013 Global Forum on Financial Inclusion for Development. With over a billion people using the postal sector for savings and deposit accounts and a widespread presence in rural and poor areas, post offices (or “posts”) can play a leading role in advancing financial inclusion. In Brazil more than 10 million bank accounts were opened between 2002 and 2011 after the post established Banco Postal in partnership with an existing financial institution. However, leveraging the large physical network of the post is not without challenges. Posts generally have little or no expertise in running a bank and the business model that a government pursues in providing financial services through the postal network may be critical to its success.
