The Bank of Starbucks

Connor Tabarrok points out that Starbucks is also a bit of a bank:

In 2011, Starbucks rolled out the ability to load money onto a virtual card via their mobile app. purchases made with these pre-loaded dollars earned extra rewards points, which could eventually be redeemed for free drinks. According to their quarterly report from this March, through the app pre-payment system and physical gift cards, Starbucks owes almost $2 billion in coffee to it’s customers.

…The company can treat this money as a 0% interest loan, and with about 10% of funds eventually being forgotten, it’s actually a negative interest loan.

Starbucks can make money on the float and it makes more money as interest rates rise. At $2 billion and 4% they can earn about $80 million annually on the float. Moreover, breakage (some money on the cards is never redeemed) is running at about 10% so that’s another $200 million a year for a grand total of $280 million or a little over 5% of the $5 billion in operating profit. Not a game changer but also not bad for free money.

As interest rates rise, the value to Starbucks of pre-loaded cards increases. So does the cost to users but I suspect supply incentives will dominate here so you can expect to see Starbuck’s pushing these cards.
