A future with fewer banks

IT IS HARD to conceive of a world without banks, partly because they are so visible. Picture the horizon of any big city, and the skyscrapers in view are usually banks. Commuters emerge from Grand Central station in New York in the shadow of the Park Avenue base of JPMorgan Chase. Morgan Stanley looms over Times Square; Bank of America over Bryant Park. In London the skyline is dominated by odd-shaped towers in the City and Canary Wharf. In Singapore the top floors of the offices of Standard Chartered and UOB house rooftop bars looking out over the entire city. Even in places like Auckland, Mexico City or Jakarta, the logos adorning the tallest buildings are those of ANZ, BBVA or HSBC.
