Maturity mismatch and incentives: Evidence from bank issued wealth management products in China

Commercial banks in China issued a multitude of wealth management products (WMPs) from 2009 to 2016. These products are largely short-term, but a significant proportion of capital is allocated to long-term investments. In this paper, we first construct a measure of WMP maturity mismatch for each bank in each quarter using R2s from regressing expected yields of WMPs on expected yields of banks’ generally claimed investment assets. The degree of maturity mismatch is positively related to banks’ quarter-end non-performing loan ratio (NPLR), after accounting for time-varying bank characteristics, bank and time fixed effects. The result indicates that severer mismatch is associated with reduced NPLR. Cross-sectionally, the positive relation is stronger in big banks and when banks had a larger NPLR in the previous quarter. The results highlight the fact that regulated commercial banks use financial innovation and exploit maturity mismatch in their issued WMPs to evade regulator's credit risk monitoring.
