In the case of financial crises, responses should come in three stages – monetary, fiscal and structural.
MONETARY RESPONSE
First, immediate monetary response is needed, potentially including emergency liquidity,
targeted bailouts, and short term interest rates.
Providing emergency liquidity (money) allows
the financial sector to continue operating day-to-day. During normal times,
financial institutions meet their day-to-day liquidity needs (e.g. depositor
demands for cash, transactions with other financial institutions) by keeping
just a small percentage of their assets on hand as cash or other highly liquid
assets.
During the initial
panic of a financial crisis though (such as August 2007 in the US sub-prime
market), people may very suddenly start worrying about their financial
institution’s creditworthiness and general ability to meet these obligations
and consequently, will try to withdraw all their money while they can[1].
And because a financial institution will only keep a small fraction of its assets
in a highly liquid form to meet its usual day-to-day liquidity obligations (and generally
can’t quickly sell sufficient of its longer term assets for their true worth), this can
cause a ‘bank run’, where even fundamentally sound and profitable financial
institutions – not necessarily through any fault of their own – can suddenly
find themselves without enough immediate liquidity to meet their day-to-day
obligations[2].
And it’s not just
depositors that suddenly increase their demand for liquidity. The institutions
themselves become less willing to lend to each other because they are less
confident about their ability to obtain finance themselves, making them more
inclined to borrow and hoard liquidity.
If these sudden
liquidity demands aren’t met swiftly, this sudden illiquidity turns into
insolvency, where heavily-indebted individuals and institutions are forced to undertake
destructive ‘fire sales’ – the sale of illiquid assets rapidly, at a fraction
of their true worth – just to meet their short term liquidity needs. And if
these individuals/ institutions are active in a number of markets, this panic
can be transmitted far and wide, as liquidity needs in one market lead to the
liquidation of assets in another, spreading to other financial institutions
(called contagion) and potentially causing the entire financial system to freeze
up, unable to operate, causing the broader economy to crash[3].
But a central bank can
provide this short term liquidity, specifically in exchange for other assets
from the financial sector. And not just to banks. And not just in exchange for
typical high-quality bank assets. The GFC – and the preceding years of
unprecedented financial innovation – showed the increasing systemic importance of
– and therefore increasing necessity of supporting – other non-bank financial
institutions (such as investment banks), new non-traditional markets (such as
derivatives) and other assets that were of poorer quality and longer maturity
than central banks normally accept as collateral. This is what the US Federal
Reserve, the European Central Bank, and the Bank of England all did in reaction
to the August 2007 liquidity shortfalls. And this just shows how dire the
situation was, and how much further central banks were prepared to extend their
support to deal with it.
Credibility is very
important for a central bank. If the public (and the financial system) believes
that the central bank has the will and the means to provide emergency liquidity
when necessary, such a panic may be prevented before it even begins – no one
will be worried about their financial institution becoming illiquid, so they
won’t ‘run’ on it. But even if a bank run does occur, the central bank can nip
it in the bud with a quick liquidity response before it spreads[4].
And if this liquidity
response (or just their credibility) is successful, central banks may not have
to resort to the next step of the monetary response – the ‘lender of last
resort’.
The central bank may
also need to provide targeted
bailouts of systemically important financial institutions, lest their failure
drag the entire system with them. This is a central bank’s fundamental role as
‘lender of last resort’. The government itself can also provide bailouts and
deposit guarantees during a crisis if central bank support isn’t sufficient. Hopefully,
the above general emergency liquidity will remove the need to bail out
individual institutions. Furthermore, ideally, such institutions would never
have been allowed to get ‘too big to fail’. But if an institution WAS allowed
to get ‘too big to fail’, bailouts represent the lesser evil between: 1. Saving
an institution that brought their problems upon themselves, potentially
encouraging future bad behaviour in the financial sector (moral hazard) or
potentially supporting insolvent institutions that end up costing more than
they’re worth; and 2. Immediate widespread disaster.
Even institutions that
did nothing wrong, and just got caught up in this system-wide liquidity crisis,
could justifiably be provided with lender of last resort support – it surely
wouldn’t be fair to let them fail over something that wasn’t their fault.
Furthermore, confidentiality of central
bank support during a crisis can also prevent them in the future. If the public
becomes aware that an institution is receiving support from the central bank,
it can spark a panic and worsen the existing liquidity crisis if other
institutions are subsequently deterred from accepting central bank assistance.
At the very least, public awareness could damage the institution’s reputation
and increase their finance costs. This is what happened when news of Bank of
England assistance to Northern Rock was leaked to the public before the Bank of
England intended – which they did – to announce it, resulting in a bank run and
the necessity of a government guarantee to quell. Consequently, perhaps such
support in the future could be more effectively kept confidential, but only
until the crisis has subsided. Transparency after the crisis is important to
ensure accountability in central bank policy and/ or the use of public funds.
But moral hazard is an
issue, and it is why central banks should generally be hesitant to spread their
support to non-systemically important institutions, and/ or to assets of lower quality and longer length of maturity – they don’t want to encourage
the financial sector to become reliant on it/ expect it in the future, thereby
encouraging the sector to take unreasonable risks.
One way to minimise
moral hazard risks is to exploit all private sector options first – ensure that
there is no way for troubled institutions to obtain the finance they need
outside of the central bank. Bear Sterns demonstrated this notion of a systemically
important institution needing to be rescued because the private sector was
unable/ unwilling until the US Federal Reserve provided a guarantee. Northern
Rock similarly had to be rescued by the Bank of England and the UK government
when private assistance wasn’t forthcoming.
Another way to reduce moral
hazard is for the central bank to lend money against good quality collateral
and at a relatively high interest rate, naturally to be paid back over time, to
discourage implicit reliance on the lender of last resort, except in an
emergency. But as mentioned above, in dire circumstances, in a widespread
crisis, limiting collateral to high quality assets may not provide sufficient
liquidity, and a high interest rate could actually worsen the situation.
Alternatively/ in
addition, central banks could be forced to allow non-systemically important
institutions to fail (even innocent ones), if it sends a message to the
systemically important ones that lender of last resort support is not a given –
therefore, don’t be reckless with your operations. Not ideal, but possibly a
necessary sacrifice. It’s a balance of risks – save the innocent and risk
incentivising bad behaviour, or sacrifice the innocent and send a message to the
potentially guilty.
Support for the systemically
important institutions that brought this pain upon themselves can also be made
contingent on the departure of the institution’s CEO/ other executives/ board
members, as well as imposing some losses on shareholders. Taking partial or
entire ownership of the institution is also an option in particularly
exceptional circumstances, for the purposes of controlling its restructure
(making it no longer ‘too big to fail’), or just closing it down slowly at a
rate that the system can handle. This makes lender of last resort support a
little like health insurance – it may keep you alive, but it’s still an
inconvenience to have to use, so you’re not going to deliberately get hit by a
bus, just because you have this insurance.
Thirdly, if this
financial crisis spills over into the real economy, a central bank must
drop short term interest rates.
This allows households, industry and government to meet their debt obligations more
easily with lower interest payments, ideally helping to maintain current levels
of consumption, investment and government spending. Lower interest rates will
also encourage them to borrow more money – ideally to finance
productive investments like property, technology, innovation, infrastructure,
etc., rather than just debt-fuelled consumption and speculation. All this – in the
immediate term – helps to prevent economic activity from crashing.
Keep in mind that
these first two monetary responses (emergency liquidity and bailouts) do not
generate ‘real’ wealth and employment in the short term, per se – rather, they
simply create a ‘floor’ underneath the economy to keep it from tail-spinning. Even
lowering interest rates only stimulates the economy indirectly via consumption,
investment and government spending. But once this floor has been created and
the initial panic has ended, if low interest rates have not sufficiently stimulated
consumption and investment, real activity can be kick-started through the fiscal response.
FISCAL RESPONSE
Fiscal response is stage two. If the financial crisis has
spread to the real economy, and low interest rates haven’t been sufficient to
reverse this, targeted tax cuts, government expenditure, and infrastructure
programs represent the catalyst to REAL economic momentum – actual wealth
and employment will start improving while the private sector is still too
nervous to make the first move. This is because during a recession, fiscal multipliers (how much an extra dollar of government spending will affect broader economic activity) are especially strong.
During
normal economic times, $1 spent by the government may only represent $1 of
economic activity in the short term (a multiplier of one) – maybe more in the
long term if spent on productive infrastructure, maybe less if some is lost in
bureaucratic inefficiencies, or if it is just transferred to wealthy
individuals/ corporations – because that dollar was simply transferred from the
private to the public sector. No new wealth was created in the short term – it
was just reallocated. As a result, during normal times, fiscal policy tends to crowd out the private sector. In such cases, the only role this reallocation can play is for social ends, rather than economic ends.
During a recession
however, fiscal policy doesn't crowd out the private sector because that spending would NOT have ordinarily occurred by the private sector
– that’s why it’s a recession. Consequently, that $1 of government spending
generates more than $1 of economic activity (a multiplier of more
than one). In fact, the IMF estimates that during such recessionary circumstances, a government that incurs debt to pay for infrastructure spending will actually drive economic activity, and consequently government tax revenue, so much that their debt-to-GDP ratio will actually fall, not increase. In these circumstances, we would not be borrowing from future generations – the debt literally pays for itself, if not through financial profitability, then through economic growth.
And once the private
sector (households, industry) sees real economic activity returning, their
confidence rises and they take over as the driving force of the economy.
STRUCTURAL RESPONSE
The third stage is a structural response. Once real activity
has returned to the economy following stage two, this will allow government,
industry and/ or households to start gradually paying down the debt
levels that triggered the crisis in the first place. Importantly, government debt
reduction is NOT the priority during a financial crisis – not when the above monetary response has made it possible to borrow money cheaply, and especially not until the economy is back on track. Government debt reduction during a slump will literally make things
worse – not just for the economy, but for the debt situation itself. By
further slowing economic activity and therefore, government revenue, austerity during a recession can cause even more money to have to be borrowed than was saved by the initial austerity efforts (recall the fiscal multipliers above), driving debt-to-GDP (and potentially even the total debt dollar amount) up, not down.
Only when the economy is back on track can it support general efforts to reduce debt levels. Debt needs to be paid off using economic growth (or at most, austerity during STRONG economic times when the economy can handle it).
Furthermore, governments
and central banks need to adequately supervise and regulate the financial
sector – bank and non-bank financial institutions alike – to ensure a similar
crisis does not happen again. Full recovery is impossible (or at least short-lived)
if the underlying causes of the crisis are not dealt with.
This response can
include higher capital reserve requirements, including liquid assets,
for financial institutions to ensure they have
adequate buffers to meet their day-to-day liquidity obligations during volatile
times and not just normal times. Major crises may still require central bank emergency
liquidity and lender of last resort support, but that’s okay – that’s what central
banks are there for. Forcing institutions to keep too much liquidity in reserve
will impede their ability to actually use it for productive long term
investments.
The breaking up of
‘too-big-to-fail’ institutions, while it may result in some efficiency losses
in the financial sector, will mean that these institutions won’t need to be
bailed out during a crisis, because their failure wouldn’t jeopardise the whole
system.
There also must be a creation of regulatory/
oversight organisations whose job is to monitor the financial sector as a
whole, identify potential problems/ excesses, and make/ enforce recommendations
to address them. These bodies don't need to be the central bank/ lender of
last resort, if there are concerns over conflicts of interest, but if they are separate,
information needs to flow readily between them to ensure timely and appropriate
action during a crisis – this was a failure with respect to Northern Rock.
Another monetary
response that was more unique during the GFC than any previous financial crisis
was the need for international cooperation between central banks and
national governments. Central bank support in one country doesn’t help a
financial institution with vast global operations that utilise numerous
currencies. For example, during the GFC, European banks experienced a lack of
liquidity in US dollars. Once this shortcoming was observed, the US Federal
Reserve, the European Central bank and the Swiss National Bank allowed
cross-country swap arrangements to meet these international liquidity needs. Central
banks also needed to make their policies consistent with each other regarding
the (looser) collateral requirements they were imposing on financial
institutions, so international financial institutions couldn’t ‘game’ between
different central banks’ policies. This kind of cooperation is only going to
become more important in the future[5].
Finally, an
appropriate central bank exit strategy is needed – they need to wind
back the support they provided during the crisis. The earlier liquidity
responses by central banks are not long term strategies – they need to be used
only during crises to buy time for the system to be properly repaired, and must
be reversed over time. This means that all the assets which central banks acquired
in exchange for their liquidity support need to be allowed to mature over time
and not rolled over/ renewed. Their collateral requirements also need to be
re-tightened to discourage moral hazard. But again – only once the system has
recovered and been repaired.
These three responses – monetary, fiscal and structural –
keep the system from tail-spinning, kick-start real economic activity and
confidence again, and address the source of the problem to avoid a repetition.
In coming blog
entries, I will discuss how Europe, the US and Australia measured up against
these responses, and how this compared to the 1929 Wall Street Crash and
subsequent Great Depression.
[1] Ironically, this is
actually perfectly rational behaviour – if doubt arises as to the future
liquidity of the financial system, it’s perfectly rational to sell first before
liquidity dries up and market failure occurs, even though the market failure
may have been avoided if no one panicked in the first place.
[2] The very nature of
banking – long term assets but short term liabilities – leaves them vulnerable
to bank runs.
[3] Although widespread
collapse of the financial sector can also occur without contagion if all
institutions are hit by the same external macroeconomic shock, e.g. oil prices,
war.
[4] Being careful not to
trigger excessive inflation or a currency collapse – capital controls during a
crisis are a potential option to reduce this risk.
