Private credit bureaus have proliferated globally in recent decades as most economies now share credit information. A new PERC study examines the impacts of shifting to full-file credit reporting on banking concentration and competition. The study finds no meaningful changes in bank concentration or market power following shifts to full-file reporting. Additionally, greater information sharing is associated with higher private lending levels. Overall, the findings suggest lender fears about full-file reporting reducing their market share are unfounded, as the credit market appears to expand without significantly impacting individual bank shares.
