Here's a discussion about what might be happening with interest rates. It highlights several popular themes.
"There are reasons to think that central banks are not the big driver of low rates. First of all, it isn’t just nominal rates that are historically low, but real inflation-adjusted rates as well. Most economists believe that real interest rates can’t be affected by monetary policy for very long. Second, most economists think that if central banks are holding rates below what private markets want, we should be seeing high inflation. We’re not. And finally, the end of the Fed’s bond-buying program of quantitative easing seemed to have only a small effect."
