This paper analyzes the linkages between banks’ profitability and the main real and financial indicators. The results, derived by means of a reduced-form model for the period 1984- 2002, highlight a strict relation between all income and cost components and the evolution of the economic cycle. Net interest income shows a high correlation with nominal GDP and the interest rate term structure; income from services and trading are also influenced by the trend and volatility of stock and financial markets. Operating expenses depend on wage dynamics and changes in a bank’s organizational structure. Simulations performed for the period 2001-02 show a good predictive power of the model
