Using a panel of accounting data for Norwegian banks over the last 20 years, the relationship between the rate of non-performing loans and different measures of competition is analysed. We find a U-shaped relationship between

The findings suggest that a continued increasing trend in concentration contributes to higher non-performing loan rates. Similar results are found when using interest margin as the measure of the toughness of competition.
