Banks have been vital to financing large engineering efforts for aeons; the Assyrians had them back when. Speaking of which there was a Tel outside of Mosul with amazing views of the Tigris and incredible work (way too heavy to carry by even a team of rapists of history) that must have been quite the amalgam of engineering, politics, and finance of pull off and build ... Eurobonds will be interesting to watch and see what results.

The distinctions between large, medium, and small banks are perhaps not as clear cut as one might think....and to stir the pot a bit, simplifying...Krugman thinks TBTF can work if managed while Greenspan thinks killing some TBTF off is not a bad thing...

The Economist has a timely multi-section report on Banking worth reading:

Special report: international banking: Banking goes digital, May 17th 2012, 4:46 from Schumpeter, Our correspondents discuss how new technologies will affect the future of retail banking, The Economist

Spain is arguably the world’s most competitive banking market. Thanks to its fiercely independent regions, it has a remarkable number of banks for its size. Even more remarkable is the number of branches, some 43,000, which works out at one branch for every 1,000 people, or about six times the number in Britain and more than twice as many as in France and America. “With too many players you end up overbanked because every bank wants to be everywhere,” says Pedro Rodeia at McKinsey. This keen competition pushed some smaller banks to lend recklessly, causing a banking crisis that blew up the economy. Yet it also forced banks to squeeze out costs, which at Santander and BBVA account for less than 50 cents of every euro they earn, despite their huge branch networks. Most large retail banks in other countries would be happy with anything below 60 cents.

Spanish banks embraced modernisation relatively late. Having been trapped in a bubble for many years during the fascist dictatorship, once they were freed they were able to leapfrog rivals in more developed markets. The most important innovation was the rapid and almost universal adoption by bank customers of electronic bill payments. Spain’s banks have a huge advantage in not having to process cheques or handle transactions in their branches. They have invested diligently in installing the latest and most effective computer systems, making their banks enviably efficient. Their rapid growth and the economic troubles at home raise some question marks. Even so, they have developed an innovative model of banking that is being exported around the world. It may also hold some clues about what banks elsewhere may soon be doing.
