Small, young private firms in China have long been struggling to obtain formal bank loans. To bypass financial constraints, these firms have resorted to alternative, less formal financing sources. In this context, Chinese authorities are aiming to develop a more formal, market-based, and better regulated credit sector. In a Staff Working Paper, I argue that carefully designed credit sector reforms are crucial to avoid throwing out the baby with the bath water. Despite the interest rate liberalisation progressively implemented by Chinese authorities, a general crackdown on alternative finance would remain detrimental to the dynamism of small enterprises. Selectively tightening the limits around informal financing could better balance financial stability on the one hand, and welfare and efficiency on the other.
