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.

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 highUnder 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.
Macroeconomic Factors: Exchange Rate
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.
June 7th 2007 11
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%.

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 system2. Weak accounting standards3. Government directs credit4. Financial institutions nationalized5. Inadequate government regulation
June 7th 2007 14
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.

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 creditrisks is harder when the economy is expanding because borrowers may be at leasttemporarily profitable and liquidBoom is often accompanied by asset price bubbles (stock market, real estate).

Micro Factors: Balance Sheet Mismatches
1. Bank assets and bank liabilities: differ in terms of liquidity, maturity, and currency of denomination.
2. Maturity and currency mismatches: more acute in a context of rapidly increasing bank liabilities (capital inflows).
3. Maturity mismatch and sequential service constraint: create the possibility of self-fulfilling bank runs.
4. Large, unhedged foreign-currency positions (banks and their customers): increase risk of default on existing loans and overall financial vulnerability to adverse (domestic or external) shocks.
5. Lending in foreign currency by banks to domestic borrowers transforms currency risk into credit risk.

Weak legislation against concentration of ownershipWeaknesses in the accounting, disclosure, and legal infrastructure: hinder theoperation 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'screditworthiness 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.

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.

Route of a classic financial crisis
June 7th 2007 21
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– excessive bank lending growth– excessive capital inflows– an overvaluation of the currency– a fall in foreign exchange reserves
→ these trends reverse after the crisis!
Can these indicators predict a financial crisis?

Early warning signals
June 7th 2007 23
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
Are financial crises only due to bad fundamentals?
June 7th 2007 24
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 ana. 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, ‘self-fulfillers’ as a liquidity crisis
Combination of both embodied in third generation models of currency crisis
What have we learned?
June 7th 2007 25
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.
What have we learned?
