Two charts, both courtesy of Holger Zschaepitz @Schuldensuehner:
In simple terms, combined value of bond and stock markets is currently at around USD137 trillion or 179% of global GDP. Put slightly differently, that is 263% of global private sector GDP. There is no rational model on Earth that can explain these valuations.
Since the start of this year, the two markets gained roughly USD15 trillion in value, just as the global economy is now forecast to gain USD3.93 trillion in GDP over the full year 2017. Based on the latest IMF forecasts, the first 9.5 months of stock markets and bonds markets appreciation are equivalent to to total global GDP growth for 2017, 2018, 2019 and a quarter of 2020. That is: nine and a half months of 'no bubbles anywhere' financial growth add up to thirty nine months of real economic activity.
Happy times, all.
