ECB bond buying from national banks, what are the national banks expected to do?
This question is now very relevant, with the ECB committing to buy over 1 trillion Euros of bonds in 2020. My understanding is that the ECB buys open market bonds, thus pushing their value up.
The goal, therefore, is to stimulate the bond market, and thus the economy.
In practice, I am still looking for information on what exactly the ECB buys with all that money.
