The ugly side of ultra-cheap money - By Bill Gross

Gresham’s law needs a corollary. Not only does “bad money drive out good,” but “cheap” money may as well. Ultra low, zero-bounded central bank policy rates might in fact de-lever instead of relever the financial system, creating contraction instead of expansion in the real economy. Just as Newtonian physics breaks down and Einsteinian concepts prevail at the speed of light, so too might easy money policies fail to stimulate at the zero bound.
