2A Role for Financial Structure?
- Traditionally money was at the centre of macro
theory of crashes - Gertler (1988) blames the Keynesian revolution
and monetarists for redirecting attention. - Gurley and Shaw (1955) focused on Credit supply
rather than monetary aggregates.
3Revisionists
- Bernanke (1983) on the relative importance of
monetary versus financial factors in the Great
Depression. - The breakdown in banking affected real activity
by choking off financial flows to certain sectors
of the economy, sectors consisting of borrowers
who did not have easy access to non-intermediated
credit. - ..worsening of balance sheets resulting from the
jump in debt service shrank borrowers
collateral
4Revisionists
- Bernanke (1983) found that financial variables
were important determinants of output - Liabilities of failed banks and businesses and
spreads between risky and safe bond rates added
considerable explanatory power to Barro-type
output equations. -
- Disruption of credit markets was not simply a
response to anticipations of future output
decline. - Hamilton (1987) and many others provide further
evidence supporting this view.
5Information asymmetryMoral hazard
- Akerlof's (1969) market for lemons influenced
Jaffee Russell (1976) and Stiglitz Weiss
(1981) - Lemons theory explains how unobserved
differences in borrower quality induces credit
rationing. - Mankiw (1986) analyzes a credit market plagued by
lemons problemsa small rise in the riskless
interest rate can lead to collapse. - The increase in the loan rate reduces the average
quality of borrowers. - This forces the loan rate up further to offset
the lemons effect. - If the lemons problem is severe enough, the
market will collapse.
6Information asymmetry
- Myers Majluf (1984) and
- Greenwald, Stiglitz Weiss (1984)
- Equity financing effects of information asymmetry
regarding the value of a firm's existing assets. - Bernanke and Gertler (1986)
- Resurrect balance sheet effects also known as
collateral effects, financial capacity
effects or debt deflation. - Gan(2007)
- Shows such effects in the Japanese economy after
the property decline of the late 1980s.
7Lessons from recent panics/crashesSeeds of a
moral hazard problem?
- Japan late 1980sBoJ too slow!
- A warning to other monetary authorities.
- Crash of 1987
- The beginning of the Greenspan put?
- South-Asian currency and bank crises 19971998
- Is the current turmoil just a repeat of this but
with Western banks now at the centre of the
storm? - Russian debt moratorium 1998
- Unobserved exposures through derivatives mkts
- LTCM
- Bailing out of LTCM inviting moral hazard problem
- Spread of systemic risk through collapse of
markets - Particularly derivatives mkts
8Any difference this time?
- Low interest rates, cheap money, yield chasing?
- Not so different from before
- Too few investment opportunities.
- Was the macro environment too loose given that
inflation was been kept under control by other
factors? - Inefficient credit ratings not a new problem?
- Peek and Rosengren (1998) report that throughout
1995 and 1996 Libor quotes for major Japanese
banks for eurodollar and euroyen borrowing rarely
differed by more than a few basis points, even
though there were substantial differences in
their credit ratings provided by the major rating
agencies.
9Any difference this time?
- More concentrated and more integrated markets?
- More Bank Regulation
- Stronger bank balance sheets following Basel I?
- More off-balance sheet activity!
- More systemic reaction to crisis.all trying to
beef-up liquidity at the same time - More transparency.MiFID, NMS etc.
- Increasing the risks in financial intermediation
10Any difference this time?
Sovereign funds Complications arising from
politics of BRICK current account surpluses in
dollars. Bad taste resulting from DPW sell-off
of ports to AIG and some reluctance to invest in
US colateralized debt. Slide of dollar could
transmit problems to BRICK Collateralized Debt
Obligations All the lemons problems you could
wish for! But not that new! The tail has wagged
the dog before. During LTCM crisis derivative
positions threatened other markets

15Recent warnings
- Giddy(1981) comment regarding the functioning of
the interbank eurocurrency market - Indeed, if it is true that the market places
great store on central bank support, it will
continue to grant credit without discrimination
to large banks. In effect the market will test
central banks mettle, and if ever the rule of
central bank rescues is broken, severe credit
rationing will occur. - Mervin King threatened such a rule break!
16Recent warnings
- G10 central banks report 1992
- the heightened concern with credit risk,
reflecting both a perception of increased default
risk and greater difficulties in assessing
counterparties strength, has led many banks to
reduce the size of interbank credit exposures
that can be authorised, to shorten the maturity
of the business they are willing to take on, and
to limit dealing activities that yield low
profits but give rise to large counterparty
exposures
17Yields at the short and long maturities
18Liquidity provision at the short and long
maturities
19Recent warnings
- Bernard Bisignano (BIS, 2000)
- Interbank lending to Asia grew enormously prior
to the Asian crisis, at times with arguably
little recognition of the quality of the
borrowing institution. International interbank
credit also declined dramatically after the
crisis erupted, contributing to a major collapse
in economic activity. - Short term IIBM borrowing was funding low quality
sovereign debt. - Giddy (1981) and Clarke (1983) pointed to the
widespread belief among market participants that
central banks would step in to support the market
if it came under stress. - Clarke reported that inquiries about
counterparties balance sheets were considered to
be in rather bad taste. Particularly if the
bank in question was a very large bank more
likely to be bailed out.
20Effects already
- Liquidity effects
- Feedback from dollar concerns
- Sovereign funds worry
- Higher yields on even govies in Europe
- Having a futures market helped Bunds
- Better functioning markets also means more
concentration in activity and therefore more
direct linkages between banking organizations and
therefore more systemic risk.
21Towards solutions
- What drives the assumption that central banks
will provide a safety-net? - Is it worthwhile trying to reduce moral hazard
and how can it be done? - Can bubbles be detected? viewed as a dead
science in academia and policy circles. - Would it be possible to coordinate CB policy so
as to reduce cheap fuelling of leveraged
investments internationally?
22Towards solutions
- By-pass the intermediary (Sell direct to surplus
countries) - This assumes intermediaries add nothing
- Can high real interest rates be good?
- In very well developed economies
- Should central banks monitor the type of
investment going on.
23Towards solutions
- Can transparency help?
- Counterparty transparency is problematic.
- No incentive to reveal debt positions so lemons
problem. - If revealed it would reduce the costs of credit
analysis and counterparty risk but increase
position risk - Would it reduce moral hazard risk?
- Bester (1985) suggested that simultaneously
offering loan rates and collateral requirements
would help. - Good borrowers would then prefer lower rates and
greater collateral given their lower probability
of potential default. - But the tail can wag the dog unless
transparency abounds.
24Hold on to your hat!
- Still a rough ride ahead!
- We may be spared a Japanese style finish
- Deflation is rather unlikely
