The privatisation experience in banking and insurance in Australia

The role of ownership in performance of financial institutions is under-examined yet remains a topical issue. Whilst ownership changes in the banking sector have been evaluated in several studies, the link with other sectors has not been a focus of in depth analysis. A controlled comparison of performance between privatising banks and insurance firms in Australia is undertaken via a ‘meso’ approach of pairing privatising with comparator private institutions across the event period. Performance is evaluated using commercial CAMEL indicators and applying Wilcoxon rank tests (Otchere and Chan 2003) which provide statistically robust findings in the small annual data samples available around the privatisation event. Performance of privatising and private institutions is found to be quite similar before and after the event. For the privatising banks, some indicator medians improved to commercial levels (CBA) or were mostly unchanged (Colonial). By contrast one of the privatising insurance institutions (Suncorp) was found to outperform the private insurance comparator while there was little difference for the other (GIO).
