Are interest rates destined to move higher, increasing the cost of private and public debt? While many experts believe that higher rates are all but inevitable, historian Paul Schmelzing argues that today’s low-interest environment is consistent with a long-term trend stretching back 600 years.

The chart “shows a clear historical downtrend, with rates falling about 1% every 60 years to near zero today,” says Bloomberg’s Aaron Brown. “Rates do tend to revert to a mean, but that mean seems to be declining.”
