This paper focuses on the possible coalition formation in the Governing Council of the European Central Bank (ECB) over the period 2007-2011. In this way, we determine a priori monetary policy stance for each European members through the estimation of Taylor- type rule. Our results show that the ECB Governing Council is strongly heterogeneous with different monetary preferences. Discrepancies among committee members could lead to potential alliances in the Council. The formation of coalition, analyzed through a cluster analysis, reveals that it could be difficult for the Executive Board to impose European perspectives. The analysis of voting power emphasizes that the Executive board will lose its strategic position when national governors form coalitions.
