Credit information sharing has been shown to have several benefits for the financial system. Reliable credit information can address the fundamental problem of asymmetric information between borrowers and lenders, it can alter borrowers’ behavior countering moral hazard, and improving repayment rates, and it can place banks in a better position to assess default risk, counter adverse selection, and monitor institutional exposures to credit risk. Perhaps most importantly, credit reporting can allow borrowers to build a credit history and to use a documented track record of responsible borrowing and repayment as "reputational collateral" to access credit outside established lending relationships. In addition, financial regulators can draw on credit reporting systems to understand the credit risk faced by financial institutions and systemically important borrowers, to define capital provisioning requirements, and to conduct essential oversight functions.
Despite the numerous benefits of information sharing for credit market efficiency, credit reporting institutions do not always emerge spontaneously. The Doing Business dataset shows that 26 percent of countries do not have any credit reporting institution at all (figure 1). Low and middle income countries have a relatively higher presence of credit registries while credit bureaus are more common in high income countries.
