We talk a lot about the falling interest rate, the too-low interest rate, the near-zero interest rate, the zero interest rate, and the negative interest rate. Hat Tip to Switzerland, where Credit Suisse is now going to pay depositors -0.85%. That is, if you lend your francs to this bank, they take some of them every year. Almost 1% of them. A bank deposit comes with a risk. But instead of compensating you for the risk, the bank pays you nothing. So its a return-free risk. And worse than that, a negative rate means that you are paying the bank in order to take the risk of lending to them.
