Reserve Bank sounds warning on house prices, page-121

Yes, what I am saying is that once interest rates bottom out, rates will gradually rise over the next few decades, there will be some spikes in some countries, but the overall trend will be up. This is completely normal as the cost of money must increase following the economic effects of decreasing cost of money.

In a normal declining interest rate cycle, speculation is worst at the bottom when rates are cheapest. The fact that this is an extended lower cycle means that speculative forces have much more time to build.

Central planners are desperate to keep rates low and to hell with the consequences. Some European countries are in negative rates, and any extended periods of negative rates will have dire consequences, many of which will be unpredictable because it is such a rare event.
This does not mean one should not invest, but one should be very careful about which speculative bubbles to participate in.
Right now we have a bond market bubble (globally), a share market bubble(in America) and isolated bubbles in other asset classes.

The bubble in some commodities popped such as oil, copper, coal and iron ore.

Below is a chart I posted a long time ago about interest rates and how dysfunctional they have become.
