Credit card rewards generate $9.2B annual wealth transfer to high earners, study finds
Academic research indicates lower-income cash and debit users subsidize premium card perks through uniform retail price increases.
The short version
- A working paper by researchers from Harvard and other universities estimates that credit card rewards transfer $9.2 billion annually to US households earning more than $150,000.
- Because merchants raise prices across the board to cover card interchange fees, cash and debit users subsidize rewards for high-income premium cardholders.
- The 2010 Durbin Amendment exacerbated this dynamic by capping debit interchange fees, leading banks to eliminate debit rewards while keeping credit card perks intact.
- Researchers note that consumer store preferences and fee negotiations by major retailers reduce the overall wealth transfer by roughly 25%.
