In my professional experience, I have had the opportunity to conduct household level interviews on savings practices (2012). Almost every woman I asked deferred to the man of the house whether that was her husband, son, or father implying that women are either uncomfortable speaking about finances or they are unfamiliar with it.
However, this is belied by my personal experience. Women in Pakistan have long utilized the Rotating Savings and Credit Association (ROSCA) model. Here, it works under the moniker of "committee". Women who know each other within a community - either geographic, religious, or family - come together once a month for 6 months or so where they contribute an equal, set amount per person to create a "pot of money". This pot of money is then distributed to one member of the committee for that month. This is repeated until each member has received a pot of money.
It would be extremely insightful to understand the needs of these women - how they handle the transacting, missed payments, disputes, safekeeping etc etc. This informal method of lending and saving has thrived for a very long time and there is a reason for that. The benefits are very compelling to the women who participate.
So far, all efforts to leverage alternative delivery channels for financial products (such as mobile money) to promote women's participation have been ineffective due, in no small part, to cultural hurdles. In order to design and build more robust and effective formal financial services for this segment of the market, it is vital to understand how the informal financial services they already participate in can be leveraged in order to encourage women to move to the formal financial sector which is believed to be safer and more effective.
