Over the past decade, it has seemed that big banks have only gotten bigger. This is down to a variety of factors - from mergers and acquisitions through to technological leverage - but the most overriding factor has been the impact of globalization. As corporations and organizations have created global supply chains, so the largest banks have tried to follow their clients' needs by creating global infrastructures. For most firms, this means is that they can now work in partnership with a bank that reflects their multinational capabilities without having to open separate accounts in each of the countries of operation.
