Why do Japanese regional banks issue subordinated debts?

This paper empirically investigates the determinants of subordinated debt issuance by Japanese regional banks during the period of 2000–2007 using a probit model. The empirical results suggest the following. (i) Throughout the period, Japanese regional banks with a lower capital ratio tended to have a higher incentive to issue subordinated debts due possibly to their counting as Tier 2 capital under the Basel Accord. (ii) During the period of banking instability (2000–2003), subordinated debt investors tended to use financial variables such as the non-performing loan ratio, ROA, and ROE to screen good banks. (iii) During the period after the banking system regained stability (2004–2007), investors tended to pay less attention to the above variables due chiefly to the mitigated default risk of these banks.
