Response to Gulliver Travails’
Comment on “Unless the Fed Goes Cold Turkey …”
Notice that my definition of TOTAL thin-air credit is the
SUM of Fed credit and depository institution (bank) credit. This is important
when analyzing the effect of a Fed purchase of securities FROM the banking
system. So, let's start with that scenario -- the Fed purchases $X of
securities from the banking system. If the banking system then uses the
reserves created by the Fed to replace the securities sold to the Fed by
acquiring $X of loans/securities from the nonbank sector, then Fed credit will
have increased a net $X and banking system credit will be unchanged (it sold $X
of securities to the Fed and purchased $X of loans/securities from the nonbank
sector). In this case, the SUM of Fed and banking system credit increases a net
$X. If the banking system has made a new loan to some entity, then presumably,
that entity makes a new purchase of something -- a good, service and/or asset.
If the banking system acquires a newly-issued security, then the security
issuer -- a household, business and/or government, makes a new purchase of
something. If the banking system purchases a "seasoned" security,
then the seller of that security might purchase a newly-issued security, which,
again, presumably would lead to new spending on goods/services in the economy.
The seller of the security to the bank, might purchase another
"seasoned" security. That's still another transaction resulting
indirectly from the Fed's purchase of securities. Alternatively, the seller of
the "seasoned" security to the bank might decide to use the proceeds
to purchase a good/service, especially in a low interest rate environment when
the inducement to postpone current consumption is so low.
Now, if the banking system purchases a "seasoned"
security from the nonbank public and the seller of that security to the banking
system chooses to simply hold more banking system deposits, then the Fed's
purchase of securities will NOT result in a net increase in spending on
SOMETHING by the nonbank public. But if the nonbank public has an increased
demand for deposits TO HOLD, and the Fed had NOT, purchased securities, which
enabled the banking system to purchase "seasoned" securities from the
nonbank public, then the net change in spending by the nonbank public would
have been NEGATIVE, rather than zero. That is, if the VELOCITY of bank deposits
were decreasing and the SUPPLY of bank deposits were constant, then nominal
transactions would have to fall according to the
identity: MV = PT.
Now, suppose again that the Fed purchases $X of securities
from the banking system. But this time, the banking system does NOT replace
these securities with new acquisitions of loans/securities. Rather, the banking
system chooses to hold an extra $X of (cash) reserves. In this case, the net
change in the SUM of Fed and banking system credit is ZERO. Fed credit
increases by $X; banking system securities decrease by $X. In this case, there
is no net change in spending by the nonbank public resulting from the Fed's
purchase of securities. This is akin to the decline in velocity of deposits
mentioned above. In this case, there is a decline in the velocity of RESERVES.
I.e., the banking system desires to hold more reserves.
If the Fed purchases securities directly from the nonbank
public, then the analysis is the same as the Fed purchasing securities from the
banking system and the banking system using the newly-created reserves to
acquire "seasoned" securities from the nonbank public. The only
difference is that "middleman", the banking system, is eliminated
from the sequence. Only if the nonbank seller of securities to the Fed desires
to hold more deposits, i.e., there is a decline in the velocity of deposits,
will there be no net increase in spending on SOMETHING in the economy.
Now, immediately after the failure of Lehman Bros., there
undoubtedly was an increased demand for federally-insured bank deposits, i.e.,
a decline in the velocity of deposits. I would argue that to the degree that
the Fed's first round of QE increased the SUPPLY of deposits as the DEMAND for
deposits was increasing, QE cushioned the negative impact on nominal spending
in the economy resulting from the decline in velocity. I suspect that now, five
years after the onset of the crisis, the demand for deposits is gradually
decreasing. So, an increase in the SUM of Fed and bank credit would likely
result in increased net nominal transactions.
I have no doubt that the increased SUM of Fed and bank
credit resulting from QE has played an important role in boosting the prices of
risk assets. Would it be preferable for growth in nominal spending on
goods/services to be weak AND the prices of risk assets be weak, too?
Although Fed QE may now be on the edge of creating excessive
growth in the SUM of Fed and bank
credit, I would argue that if the Fed had NOT engaged in QE after the 2008
crisis, economic performance would have been weaker than it has been. To those
who argue that QE does NOT promote faster growth in nominal spending, I would
counter that without QE, growth in nominal spending would have been even
weaker.

Thanks for the thorough reply. I think you rightly point out that this comes down to a question of the velocity of bank reserves and deposits. In a world of excessive leverage, near-zero interest rates, interest paid on excess reserves and deposit insurance, I think it's arguable that reserves are a near perfect substitute for government securities held by banks, and deposits are a near perfect substitute for government securities held by non-banks. If that's the case, banks will happily sit on excess reserves swapped for bonds, and the non-bank public will willingly hold bank deposits in lieu of bonds. In such a scenario, QE is unlikely to significantly impact spending though it is likely to goose risk asset prices. But you might be right that risk appetites are rising, in which case we could have a little economic boom next year.
ReplyDeleteAs for whether it would have been preferable over the last few years to see weak nominal spending AND weak asset prices, that sounds like a good subject for an Austrian PhD thesis. My hunch is that it's too soon to answer that question---ask me again in ten years. :-)
