You need to recompile the US Federal Reserve System balance sheet so that I could see major changes in Fed monetary policy since 2008. More specifically I would like to see the amount of government bonds, mortgage backed securities, bonds of government enterprises as separate items in the asset part of the BS.
The data can be annual, but weekly data might offer more attractive visualization.
as to the depth of the series: start with year 2000.
