Using Flow of Funds Accounts table L.109 define items from the
simplified Fed balance sheet:
MPA = L.109.12, Monetary policy assets equal Treasury securities
held outright.
CPA = L.109.01 - MPA, Credit policy assets equal total assets minus
MPA
CC = L.109.37, Currency outside banks.
FF = L.109.28 + L.109.35 + L.109.36, Fed funds equal reserve
balances, balances to rest of world, and to GSEs.
The chart below shows:
MPA = CC, (approximate) on the period until late 2007
MPA = FF, (approximate) on the period staring in 2010 to year end
2011
The simplification defines monetary policy assets MPA as liabilities
of Treasury, and credit policy assets such as discount loans,
special liquidity programs, repo, and private asset purchases under
QE as liabilities to the private non-sovereign sector and assets of
Fed. Other Fed assets are considered negligible so CPA may be
overstated (not shown in the plots below).
I am not clear on the policy rationale or implications of setting
Fed setting MPA = FF but it is an interesting observation for
contemplation and potential discussion.
