IFC's card-rail guarantee projects $400 of payment volume for every dollar behind it

The projected volume is 400 times the guarantee sitting behind it ^[2]. That ratio is not absurd on its face, because the risk being covered is short-dated. Settlement exposure exists only in the window between authorization and final clearing, and covering it frees capital that would otherwise sit idle as collateral ^[8]. The same dollar of guarantee therefore backs a new transaction once the last one clears, and how many times it turns depends on the length of that window and on how long the program runs. The material attaches five years to Visa's facility and no period at all to the $280 billion ^[8].

The ceiling is also addition. Mastercard's facility plus the Visa five-year figure comes to exactly the $700 million on the top line ^[1]. The two inputs are defined differently, though. One is the size of a settlement-exposure facility ^[4], the other is volume supported over five years ^[5]. The headline number adds a stock to a flow.

Divided among the roughly 50 enrolled lenders, Visa's share works out to $4 million each over five years, or $800,000 a year ^[3]. Across roughly 14 countries in Latin America and the Caribbean, that is about three and a half institutions per country ^[4]. The selection rule is the credit rating: the target set is lenders without investment grade ^[6].

IFC is not paying for transactions. The program works on the institutions that issue cards, connect merchants and settle payments ^[9]. Makhtar Diop, IFC's managing director, described digital payments as one of the most effective ways to create jobs and bring people into the formal economy. He said collateral requirements have too often blocked expansion, according to the announcement ^[10]. Mastercard tied its facility to a goal of helping 500 million people and small businesses move toward financial health by 2030 ^[11]. The 90 million active users projected here would be 18 per cent of that ^[7]. Of those users, 39 million are projected to be women, or 43 per cent ^[6].

My read is that this is cheap optionality for the networks. Mastercard and Visa get issuance and acceptance in markets where their own collateral terms were the constraint keeping smaller and lower-rated lenders out ^[2]. Neither writes a cheque unless a settlement fails, because the credit settlement risk on enrolled institutions sits with IFC ^[5]. The counter-argument is stronger than it looks. If collateral is genuinely what keeps a lower-rated bank off the rails, a revolving guarantee is the right instrument, and it costs nothing in the years nothing breaks. The figure that would settle the question is activation. IFC projects 360 million more cards against 90 million active users ^[7], four cards for every active user ^[5], and interchange only arrives on the cards that get used.
