A new article online at The Economist will make for sobering reading at the marketing departments of big banks.

In addition to poor customer satisfaction rankings, it seems that, in America at least, a fair share of disgruntled customers are moving their money away from large banks. The article mentions a Zogby poll released earlier this month that showed a third of Americans considered switching to a smaller bank because they disliked the “policies or behaviour” of big banks. Some 14% of respondents had actually moved their money from a large bank to a small bank over the past year, with 9% doing so to protest the behaviour of large lenders.
