We show that banks manipulate borrowers' credit ratings before sharing them with competing banks. Using a unique feature on the timing of information disclosure of a public credit registry, we disentangle the effect of manipulation from learning of credit ratings. We show that banks downgrade high-quality borrowers for which they have positive private information to protect their informational rents. Banks also upgrade low-quality borrowers with multiple lenders toavoid creditor runs. Our results suggest that credit ratings manipulation limits the positive effects of credit registries' information disclosure on credit allocation.
