Definition of a Banking Crisis
1. Ratio of nonperforming loans to total bank loans
exceeded 10%.
2. Cost of the rescue operation (or bailout) was at least
2% of GDP.
3. Episode involved a large-scale nationalization of banks
(and possibly other institutions).
4. Extensive bank runs took place or emergency
measures (deposit freezes, prolonged bank holidays, or
generalized deposit guarantees) were enacted by the
government.

Impact of financial crises on long-run growth
Financial crises have a large, negative impact on GDP.
Countries typically do not return to their old growth path (IMF research).
GDP loss is largest for poor countries.

Macroeconomic Factors: External shock
A change in the terms of trade.
An unanticipated drop in export prices, for instance, can impair the capacity of
domestic firms (in the tradable sector) to service their debts.
This can result in a deterioration in the quality of banks' loan portfolios.
Adverse shock to domestic income associated with a decline in the terms of
trade: may slow output and raise default rates.

Macroeconomic Factors: External Shock
Capital outflows induced by an increase in world interest
Drop in deposits; may force banks to liquidate long-term assets to raise
liquidity or cut lending abruptly. May entail a recession and a rise in default
rates.

Macroeconomic Factors: Exchange Rate
A credibly-fixed exchange rate provides an implicit guarantee (no foreign
exchange risk) which may lead to excessive (and unhedged) short-term
foreign borrowing.
This increases the fragility of the banking system to adverse external shocks,
particularly if the degree of capital mobility is high
Under any pegged rate regime, capital outflows affect the financial system
through an expansion or contraction of bank balance sheets; they can lead to
instability in the banking sector.
A flexible exchange rate may also create problems
An abrupt outflow of capital can lead to a sharp depreciation of the nominal
exchange rate.
The depreciation may raise the domestic-currency value of foreign-currency
liabilities, for banks and their customers.
Large, unhedged foreign-currency positions increase risk of default on existing
loans and vulnerability to adverse (domestic or external) shocks.
The fall in borrowers’ net worth may also lead to a rise in the finance premium
and to increased default rates; higher incidence of nonperforming loans may
lead to a banking crisis.

Macroeconomic Factors: Opennes
Countries of currency crashes tend to be less open to trade, especially those
with sudden stops as well. An increase in trade openness of 10 percentage
points decreases likelihood of a sudden stop (definition of Calvo, et al.) by
approximately 32%. Average Opennes and Fitted Opennes by category of Crisis

Macroeconomic Factors: Opennes
Countries that are less open to trade are more prone to sudden stops &
currency crashes. Increase in openness also decreases the likelihood of
currency crash, defined as 25% increase in exchange market pressure≡

Macroeconomic Factors: Financial Repression
Financial system in most developing countries is “repressed” by government
interventions. This keeps interest rates that domestic banks can offer to savers
very low.
By keeping interest rates low, it creates an excess demand for credit. It then
requires the banking system to set a fixed fraction of the credit available to
priority sectors.
Combination of low nominal deposit interest rates and moderate to high
inflation has resulted in negative rates of return on domestic financial assets.
Financial Repression Leads to Low Growth:
1. Poor legal system
2. Weak accounting standards
3. Government directs credit
4. Financial institutions nationalized
5. Inadequate government regulation

Macroeconomic Factors: Domestic shock
Domestic shock: increase in domestic interest rates (to reduce inflation or
defend the currency). Slows output growth and may weaken the ability of
borrowers to service their loans; may lead to an increase in non-performing
assets or a full-blown crisis.

Macroeconomic Factors
Credit Booms: Rapid increases in bank credit to the economy.
Source of increase in banks' capacity to lend: often large capital inflows.
Often at the expense of credit quality. Distinguishing between good and bad credit
risks is harder when the economy is expanding because borrowers may be at least
temporarily profitable and liquid
Boom is often accompanied by asset price bubbles (stock market, real estate).

Micro Factors: Government interference
If lending decisions remain subject to government discretion: It will encourage
reckless behavior by bank managers; poor quality of loan portfolios. Liberalization
will not improve credit allocation or deepen financial markets.

Micro Factors: Weak Regulatory and Legal
Framework
Weak legislation against concentration of ownership
Weaknesses in the accounting, disclosure, and legal infrastructure: hinder the
operation of market discipline and effective banking supervision.
Accounting rules for classifying assets as non-performing:
Often not tight enough; make it easy to conceal losses.
Often depend on payment status, not on an evaluation of the borrower's
creditworthiness and the market value of collateral.

Micro Factors: Premature Financial Liberalization
Evidence of financial liberalization exacerbated by financial weaknesses in
developing countries.
Banking crisis more likely in liberalized financial systems, with
significance placed on strength of institutional environment.
Prior to liberalization banks and other financial institutions enjoy
substantial rents.
Liberalization leads to increased competition, higher marginal cost of
funds, higher bank deposit rates and banks responding by increasing the
riskiness of their loan portfolios.

Route of a classic financial crisis
Stage I Banking crisis
Domestic financial fragility due to ill-devised financial
liberalisation; under-regulated and over-guaranteed banks.
Large capital inflows; bank lending boom, but poor quality
of bank loans. Banking sector increasingly vulnerable,
possible bank runs.
1) Deterioration of firms and bank balance sheets.
2) Drop in asset prices.
3) Increase in uncertainty.
1) + 2) + 3): Problems of asymmetric information increase.
Stage II Currency crisis
Loss of confidence (foreign) investors; pressure on the
exchange rate.
Currency crisis and reversal of capital flows;
4) Debt-deflation (debt in foreign currency).
5) Interest rate increase.
4) + 5): Further increase in problems of asymmetric
information.

Empirical evidence of twin crises


•
Do banking crises typically precede currency crises; do
currency crises deepen banking crises?
Are both types of crises caused by bad fundamentals?
Kaminsky and Reinhart (1999) find supportive evidence for
both, showing that in the build up to a crisis, one typically
observes:
– excessive liquidity growth
banking crisis
– excessive bank lending growth
– excessive capital inflows
currency crisis
– an overvaluation of the currency
– a fall in foreign exchange reserves
→ these trends reverse after the crisis!
Can these indicators predict a financial crisis?

Are financial crises only due to bad fundamentals?
Note that the analysis so far:
• attributes financial crises to a certain extent to weak domestic
fundamentals
• implicitly assumes that financial crises are essentially solvency crises
So, what about international investors?
Recall currency crises models incorporating self-fulfilling expectations :
a financial crisis may also result from a liquidity shortage created by
international investors, while fundamentals were intrinsically sound!
A crisis occurs solely because portfolio investors withdraw their funds
to make a speculative gain

What have we learned?





Financial crisis arise from disruptions on financial markets that
increase the asymmetric information problems such that the financial
system can no longer efficiently allocate funds
Disruptions can be caused through an
a. internal channel (leading to a banking crisis)
b. external channel (leading to a currency crisis)
c. both (leading to a twin crisis)
Level of private risk determines domestic financial fragility,
determined by
a. moral hazard (guarantees)
b. excessive optimism
‘Fundamentalists’ view a financial crisis as a solvency crisis, ‘selffulfillers’ as a liquidity crisis
Combination of both embodied in third generation models of
currency crisis
June 7th 2007
24
What have we learned?
Capital account liberalization with macro and financial
weaknesses in developing countries is the responsible of
financial crises
In this case, open the market in a phased manner (1%,
3%, 5%, etc.)
Change the maturity structure of foreign capital.
Not capital control
Financial integration helps developing countries to
improve their financial markets, enhance governance,
impose discipline on macro policies, break power of
interest groups that block reforms, etc.
