The worst financial crisis since the second world war has not only forced governments across the western world to step in and rescue giant institutions. Amid the turmoil, there has also been a tectonic shift in banking's centre of gravity.
A decade ago, a list of the world's largest financial institutions was dominated by banks from the US and UK. Today, just four of the top 20 have their headquarters in the US, still the world's largest economy. HSBC, at heart an emerging markets bank, is Britain's sole representative.
After writing off more than $1,000bn (€734bn, £691bn) on complex debt instruments and raising hundreds of billions of dollars in fresh capital, many banks have watched their market value shrink to a fraction of its level at the peak of the boom.
