The treasury is pumping in $85 billion a month into the stock market, a market that is only $15 trillion in the first place. In other words, the fed is putting in 8% ($1.035 trillion) each year for the past 5 years. According to some report the fed has put in over $3.2 trillion.
You’ve heard this as “Quantitative Easing (QE)”.
The big question is if the fed is propping up the market with 8% per year, why hasn’t the market grown by at least that much?
Asset values on paper have - relative to the true value.
The markets aren’t growing by the Fed’s 8% injection each year because the overall wealth in the U.S. is substantially larger than the $15 Trillion size of the markets.
