1996~2002년 유럽 은행 산업 연구. trading activities의 증가가 반드시 higer risk와 연관된 것은 아니며, 작은 은행들의 경우에는 더 낮은 자산 위험, 디폴트 위험과 관련이 있음.
The purpose of this paper is to investigate the relationship between bank risk and product diversification in the changing structure of the European banking industry. Based on a broad set of European banks for the period 1996–2002, our study first shows that banks expanding into non-interest income activities present higher risk and higher insolvency risk than banks which mainly supply loans. However, considering size effects and splitting non-interest activities into both trading activities and commission and fee activities we show that the positive link with risk is mostly accurate for small banks and essentially driven by commission and fee activities. A higher share of trading activities is never associated with higher risk and for small banks it implies, in some cases, lower asset and default risks.
