I found the attached article a good read, so thought I would share with ASF.

Not really anything we can do about low interest rates other than accept "it is what it is" and make the appropriate modifications to any valuations. I think we will be in a low growth economic environment for many years...
Excellent stuff here. I want to see the "interest rate room" too!
Even if you take issue with my proxies for expected inflation (the actual inflation rate in the US each year, as measured by the CPI), real growth (the real growth rate in US GDP and the interest rate on a guaranteed investment, the graph sends a powerful message that risk free rates are driven by inflation and real growth expectations. If expected inflation is low and real growth is anemic, as has been the case since 2008, interest rates will be low as well and they would have been low, with or without central bank intervention.
This message is even more amplified when you consider that in a credit based monetary system, Gov bonds are essentially claims on the future productivity of the tax base of a given country, hence the expected return to be tightly coupled with forecasts on the productivity (e.g. inflation and growth) of that tax base.
