The Indian commercial banking sector is characterised by both a high averag
e non-performing share in total bank advances and a high dispersion between
banks. This paper presents the findings of a formal attempt to explain int
er-bank variations in NPAs for the year 1996-97. The specification tests fo
r the impact of region of operation on domestically-owned banks, as measure
d by percentage branches in each of a set of state clusters. One cluster of
three eastern and seven north-eastern states carries a robust and statisti
cally significant positive coefficient; another cluster of the southern and
some of the northern states carries a significantly negative coefficient.
These findings bear out those of Demirguc-Kunt and Huizinga on the signific
ance of the operating environment for bank efficiency. No sustainable impro
vement in the performing efficiency of domestic banks is possible without p
rior improvement in the enforcement environment in difficult regions of the
country. Another finding of some importance is that it is not foreign owne
rship in and of itself so much as the banking efficiency and technology cor
relates of the country of origin of the foreign bank which determine NPA pe
rformance in the Indian environment.
