This paper aims to examine the degree of dispersion in the loan pricing of commercial banks and its association with competitive conditions. To this end, an indexation mechanism processing a novel bank-level dataset is proposed to quantify the lending rate variability in general-purpose, vehicle, and housing loans for the period January 2007-April 2020. In panel convergence tests, we show that there exists heterogeneity in long-term co-movements in banks’ loan pricing, while periods following the tightening in financial conditions display short-term deviations from general tendencies demonstrated by dispersion indices. The methodological setting also entails the construction of competition indicators for total and segment-based credit market developments. The competitive conditions monitored by Herfindahl-Hirschman Indicator (HHI) present that housing and vehicle loan segments have been concentrated in recent years. Quantile regression results further validate that improvements in the competition are associated with a lower level of lending rate dispersion in housing and vehicle segments in a statistically significant manner, whereas this relation is not applicable for general-purpose loans.
