The Impacts of Diversification Strategies of Turkish Banks on Their Profitability and Risk: A Panel Data Analysis
Öz
This paper empirically analyzes the effects of product (loan), sector and income diversification
strategies on the performances and risks of Turkish commercial banks over the period 2005–2016, in which
2008-2009 treated as a crisis period. Profitability is measured by Return on Assets ratio and natural logarithm
of Non-performing Loans is used as a proxy of risk. We evaluate the different dimensions of diversification
and using the Entropy methodology to distinguish the total diversification into related and unrelated
components. Diversification is captured in three broadly defined dimensions: incomes, products and sectors.
Then, we associate all dimensions of diversification with bank profitability and risk measures, across banks
and in years, via panel data analyses. In this way, the paper aims to provide recent evidence for Turkish
banking sector’s diversification strategies and their outcomes. Our findings indicate that, to be especially
dominant on the within groups, income and product (loan) diversification increase return on assets while
decreasing loan losses; sectoral diversification decreases profits, but increases risk.
