Synopsis This book attempts to exercise a rare restraint in two very crucial and controversial areas of global bank mergers by blindly extolling the virtues of mega bank mergers and the ceaseless flow of economies of scale it supposedly brings; and to resist the temptation of being US-centric. It projects the contrarian viewpoint that argues against indiscriminate mergers. It also analyses almost every type of impact bank mergers may have on economies of scale, efficiency, competition and stability, employee bargaining power, etc. It further examines the impact bank mergers have on consumers, borrowers and on shareholder returns, apart from looking at various country experiences including the EU cross border experience which are riddled with a typical xenophobia.
