The Programme

Scale2Save is
all about balance

WSBI and Mastercard Foundation collaborate to establish the viability of small-balance savings in six African countries.

How does it work?
Scale2Save is a programme that tests and applies with partner banks in Africa new business models that focus on people’s sensitivity to price and demand of bank services and products. Aimed at supporting banks to reach scale and sustainability with low-balance accounts, the programme seeks to target low-income, unbanked people and to address account dormancy and inactivity rates by them.

Programme work is anchored by developing viable business models with regional banks that create high-impact results that widen financial inclusion in a business-sustainable way. To do this, Scale2Save relies on customer insight to help develop those models by working together with local financial institutions and partner organisations. Scale2Save balances project work with research conducted and shared among partner banks and the wider sector.

At the same time, Scale2Save is committed to boost banks’ reliability too. That means weaving the programme’s aims into the fabric of partner bank strategies, encourage needed culture change within their organisations while fostering a continuous learning environment for people working within them.

Why is this important?

  1. People boost their well-being when they have access and make use of savings mechanisms like a basic account.
  2. There is need to widen financial inclusion to unbanked people and demonstrate to them that banks can be trusted partners in their financial lives.


​​Scale2Save is built on a solid base

These key questions guide us throughout the entire process:

  • Which business models result in sustainable business cases for financially disadvantaged segments?
  • Does greater customer centricity lead to customer growth and more active customer bases?
  • What are the causes of the high degree of account inactivity in the target countries, and worldwide?
  • What are the most effective drivers of usage?
  • Which innovative approaches are most successful in stimulating account activity among financially disadvantaged people?
  • To what extent do different pricing models stimulate demand for financial services from banks?

From 2008 to 2016 WSBI already realised the

Doubling Savings Accounts programme.

  • 2.2 million new and active savings account customers;
  • More than 30,000 village groups linked up through mobile technology;
  • 2,250 service points connected digitally.
