How Does One Explain Negative Interest Rates?

I see that some of the smartest people on the money channel, CNBC, are at loss for words to explain negative interest rates in Europe and super low rates here in the US. Why they say would anyone invest money to get back less over time. (For me, personally, it is wonderful situation since falling rates are driving up the values of my older bonds, but I digress.)

I think what these experts are missing is that the world is awash in cash because money is not being invested in worthwhile things like rebuilding infrastructure and other useful things that benefit society such as education and healthcare. Instead the hoarding one percent has been stuffing its trillions in offshore bank accounts all over the globe.

So the banks say we don’t need all this cash. Therefore we are in effect going to charge you a storage fee for holding your money, which equates to negative interest rates.

Then you say, why don’t these moneybags simply invest in other instruments of value like stocks? The short answer is that with markets and economies around the world topping out and with Trump’s crazy game of trade war chicken with China pointing to disaster, it is far safer for the fat cats to keep their mountains of cash in slightly hemorrhaging bank accounts.

Apparently even over-the-top greed has its limitations.
