The goal of such rates is to force banks to lend their excess reserves. The assumption is that such lending will boost aggregate demand and help struggling economies recover. Using the same central bank logic as in 2008, the solution to a debt problem is to add on more debt. Yet, there is an old adage: you can bring a horse to water but you cannot make him drink! With the world economy sinking into recession, few banks have credit-worthy customers and many banks are having difficulties collecting on existing loans.

The shale oil bust has left many US banks with over a trillion dollars of highly risky energy loans on their books. The very low interest rate environment in Japan and the EU has done little to spur demand in an environment full of malinvestments and growing government constraints.
