What’s wrong with this scheme? Several things. First, many small banks have more money than they can profitably invest locally. As Barbara Garson shows in her wonderful book, Money Makes the World Go Around, the portion of her book advance she deposited in tiny upstate New York bank was probably lent via the fed funds market to Chase, where it entered the global circuit of capital. This is not at all uncommon. Money is fungible, protean, and highly mobile even when it looks locally rooted. That very mutability is part of what makes money so valuable: it’s the ideal form of general wealth that can instantly be turned into caviar, lodging, Swedish massage, or shares of Google.
