The Medici Bank Financial and Commercial Operations

Abstract

According to the articles of association forming the Medici partnerships, the purpose of the banco in Florence and of the branches abroad was “to deal in exchange and in merchandise with the help of God and good fortune.” When we ask just what is meant by dealings in exchange and in merchandise, we are led to examine how the Medici raised the funds with which they operated, to study their role as fiscal agents of the papacy and lessees of the Tolfa alum mines, to consider the technique they used in international banking, and to look into the reasons for their failure. The Medici did not innovate in international banking, they followed existing business practice; but their records are an extremely valuable source of information, if only for the sake of comparison. Let us begin by finding out what is meant by dealings in exchange and then tackle the other problems.
