Central Bank Money Printing Central banks generally increase assets by printing money and buying them, so the charts below are indicative of their money printing. Historically, increase in central bank balance sheet (i.e. increase in money printing and supply of money) has led to inflation in goods and services (this is offset by deflation or wealth destruction and a bunch of other factors). Recently most of the money printing has been used to buy financial assets--for instance, the JCB is a big owner of Japanese stocks--so it is not clear to me if the situation will be similar to the inflationary busts we have seen in the past. Beyond inflation, too much central bank asset purchases also distorts the market and crowds out the private sector--not a good thing from a capitalist point of view (private sector makes better capital allocation decisions than the government). It's interesting how the main 3 developed country central banks have behaved over the last decade.
