The year 2011 did not fair well for the banking sector as many banks lost substantial value by the end of the year.

Some of the problems faced by banks are increased regulatory requirements, declining margins, and loss of revenue in their fee business. Above all, the economy slowed down overall.

The worst performing bank for the year 2011 is Lloyds Banking Group, that lost almost 61% value as its share price declined to around $26. This is mainly attributed to low investment banking activity (revenue) and weaker economy. The bank following Lloyds is the Bank of America that lost 59.5% in share price.
