Basel 3, QE and Bank Reserves
Why QE didn't devalue the Dollar...
CENTRAL-BANK balancesheets are a function of the "demand for money", writes Nathan
Lewis at New World
Economics.
This "demand" basically taking two forms: banknotes and
coins among the general
public, and bank reserves (deposits at the Federal Reserve) among banks.
It is
fairly easy to see that the
public holds exactly the amount of banknotes that it wishes, and no more. At any time, if people wanted
to hold more banknotes, they
could go to their nearest ATM machine and get more.
Since bank deposits are
much larger than banknotes
outstanding, in general it is very easy to acquire more banknotes. Conversely, if people hold more
banknotes than they would like,
they would deposit them in banks. If banks ended up with a consistent oversupply of banknotes – pallets
and pallets of banknotes that
nobody wanted – they would trade them with the Fed/Treasury for bank reserves.
Thus, the total base money –
of bank reserves plus notes and coins – is a fixed number determined by the Federal Reserve, but the mix
is determined by private
behavior.
I have characterized the increase in bank reserves since 2008 as a
matter of banks wanting to hold
more reserves. This is why this very large increase in supply was not met with a very large decline in
the value of the currency,
which comes about when supply is in excess of demand.
Broadly speaking, this
supply met increased demand from
banks to hold reserves on their balance sheets. This basically represented a return to "1950s-style"
norms in banking, where bank
reserves would be about 10% of total assets. For US domestic banks, the ratio is about 8%
today.
Huge
increase in
bank reserves since 2008, but also freakishly low levels before 2008.
This
increase in reserve demand among
banks makes sense from a business perspective, independent of regulation (for example, the very large
holdings of bank reserves in the
1930s, far in excess of regulations), but it has also been reflected in regulation.
Federal Reserve reserve
requirements haven't changed much, and are still very, very low. However, Basel III requirements have
changed a lot.
Basel III was agreed on in November 2010, when the 2008-2009 crisis was acutely remembered.
In general, I like the return
to "1950s-style" reserve holding patterns among banks, so I am also broadly in favor of the Basel III
changes.
The Basel III requirements have two aspects, the "Liquidity Coverage Ratio" or LCR, and the
"Net Stable Funding Ratio" or
NSFR. They are complicated. The important thing is how it plays out in real-world action.
The interesting
thing is that these requirements have been slowly ramped up, and had full implementation only in
2019.
Take
J.P.Morgan Chase's latest annual report for instance. We find that the "high quality liquid assets"
amounted to $529 billion at the
end of 2018, which included $297 billion of "eligible cash" which "represents cash on deposit at central
banks, primarily Federal
Reserve Banks." This produced an LCR of 113%, which was a little (13%) in excess of the Basel III
requirement of 100%. Since a little
cushion is necessary to keep from falling beneath the requirements, 113% is about the "effective minimum
requirements."
The total assets were $2,622 billion. So the ratio of central bank deposits ("bank
reserves") to total assets was $297
billion/$2,622 billion, or 11.3%.
In other words, big banks like JPM are
holding large reserves because they
have to, to comply with Basel III, and also because – I argue – that it is a good idea.
Obviously, if banks
are going to comply with these requirements, then these bank reserves must exist, and that is why
central bank balance sheets, in
particular the Federal Reserve in this case, are larger than they were in the past.
In the past, "cash
assets" were a mix of Federal Reserve deposits and other instruments, but today they are basically Fed
deposits exclusively. This is
also the way it should be in my opinion, and also the way it was in the 1950s. Here we see that the
recent bank reserve/assets ratio,
among domestic banks, is about 7%. This is way below the 11.3% that is basically a requirement at
JPM.
In
short, "cash assets" (bank reserves) have been plummeting. They are way above the levels of early 2008,
but not very high if we now
expect banks to hold 10% of assets in the form of bank reserves at the Fed.
