Financial Crisis Theories Explaining the 1997 Thai Financial Crisis
Il-Hyun Yoon*
Abstract
Two models were developed to explain financial crises; first-generation and secondgeneration models. First-generation models view crises as the unsustainable fiscal and monetary
policies incompatible with a pegged exchange regime, or fundamental imbalances. The secondgeneration crisis models highlight self-fulfilling expectations and multiple equilibria. After the 1997
Asian financial crisis, alternatives to the existing models emerged. Moral hazard, financial fragility,
balance sheet imbalances and contagion are captured in the so-called third-generation models. This
study reviews models of financial crisis and examines the Thai financial crisis which spilled over into
the rest of Asian region in 1997-1998. The Thai currency was the target for speculative attacks due to
the expectation that the country’s increasing current account deficit could keep the fixed exchange
rate regime no longer sustainable. [E44, F31]
Keywords: contagion, financial crisis, first-generation models, self-fulfilling expectations, speculative
attacks.

1. Introduction
Until the early 1970s, under the Bretton Woods system,1 the international payments system
was shaped by Keynes’s incompatibility thesis that “flexible exchange rates and free international
capital mobility are incompatible with global full employment and rapid economic growth in era of
multilateral free trade” (see Davidson (2001)). The global economy experienced unparalleled growth
and prosperity in a stable international monetary system under widespread capital control and
financial market regulations.
In the 1970s, however, the accelerating growth of financial markets and the abandonment of
the Bretton Woods system, in favour of a regime of floating exchange rates, led to increasing
instability with volatile exchange rate movements and very large short-term capital flows. Especially,
since 1973, when the oil price shock created huge international payments imbalances and unleashed
inflationary pressures in oil-importing nations, the international financial system has grown
progressively more fragile with recurrent crises in financial markets.
The 1990s witnessed several episodes of currency turmoil, most notably the EMS crisis in
1992-93, the Mexican crisis in 1994-95 and the Asian crisis in 1997-98. However, the economic
effects of the Asian crisis have been especially devastating. During the first year of the crisis, the
currencies of the five affected countries depreciated by 55-70 per cent (with Indonesian rupiah
devalued by more than 500 per cent depreciation), dwindling substantially the wealth of the five
success economies (see Table 1). The crisis was triggered by Thailand's abandonment of the peg of its
currency to the US dollar on 2 July 1997.
There have been some existing models to explain the currency crisis (so-called first- and
second-generation models). These models, however, are not sufficient to explain the Asian financial
crisis. The Asian financial crisis brought about the advent of alternatives to the existing models.

It is referred to as the international monetary system that prevailed from the end of World War II until the early 1970s,
based on stable and adjustable exchange rates.

This paper reviews various financial crisis theories in the literature and investigates the Thai
financial crisis which was the origin of the contagious economic turmoil in the whole Asian region.
The rest of the paper is organised as follows. Section 2 introduces financial crisis theories
and section 3 investigates the Thai financial crisis while section 4 concludes.
2. Financial Crisis Theory
After the collapse of the Bretton Woods system, as Tobin warned,2 there have been a string
of crises in the global financial markets. Starting with the Latin American debt-liquidity in the early
1980s, there had been many crises before the 1997 Asian crisis, including three Scandinavian
countries (Norway, Sweden and Finland) in the late 1980s-early 1990s, the EMS currency crisis in
1992, and the Mexican Pesos crisis in 1994. Even after the Asian financial crisis, Russian crisis and
Brazilian crisis followed in 1998 and 1999, respectively. More recent episodes of the financial crisis
include the Turkish crisis of February 2001 and Argentina’s crisis of December 2001.
In order to investigate what a financial crisis is, the problem of asymmetric information, which
plays an important role in financial crises, needs to be examined. Asymmetric information can be
described as a situation where one side to a contract has much more exact information than the other
side. The problem of asymmetric information is in turn the cause of two major concerns in the
financial system: adverse selection and moral hazard. Adverse selection occurs when the potential
borrowers who are the most likely to produce an adverse outcome are the ones the most likely to be
selected. Exploiting the lender’s lack of information, borrowers undertaking risky activities find it
convenient to hide true nature of a project.
2
Tobin warned in his ‘The New Economics One Decade Older’ (1974, Princeton) that “free international financial markets
with flexible exchange rates can be extremely volatile and can be therefore have a devastating impact on specific industries
and whole economies” (Davidson (2001: 14).
130
Moral hazard happens in a situation where one party of a contract will do well in case of a
favourable outcome, but will not suffer even though the outcome is negative. In that case the other
party of the contract will bear most of the loss. Corsetti, et al. (1999b) found the existence of moral
hazard when domestic financial institutions believe government will intervene to help if they are in
financial trouble. The moral hazard leads to over-borrowing and over-lending.
Using the two problems arising from asymmetric information, Mishkin (2001) provided the
following definition of a financial crisis:
A financial crisis is a disruption to financial markets in which adverse selection and moral
hazard problems become much worse, so that financial markets are unable to efficiently
channel funds to those who have the most productive investment opportunities.
The recurring financial crises have led to a proliferation of explanations about its origin.
Traditionally (before the 1997 Asian crisis), there had been a long-standing debate between two
competing interpretations of the currency crisis: so-called “first-generation models” and “secondgeneration models”.3
2.1 First-generation models
In the literature on the currency crisis, one approach – often referred to as first-generation
models or exogenous policy approach – views a currency crisis as the natural outcome of
unsustainable policy stances incompatible with a pegged exchange regime or structural imbalances
while the other approach – known as second-generation models or endogenous policy approach –
regards the crisis as self-fulfilling, expectations-driven, processes, not driven by fundamental factors.
First-generation crisis models, pioneered by Krugman (1979) and refined by Flood and Garber
(1984), explain a crisis as the product of fiscal deficits. The government with a persistent deficit
3
A currency crisis can be defined as a speculative attack on a country’s currency that can result in a forced devaluation and
possible debt default. Investors “flee a currency en masse out of fear that it might be devalued, in turn fuelling the very
devaluation they anticipated”. (Krugman (2000)).
131
would exhaust its limited stock reserves to defend its exchange rate and eventually abandon a fixed
exchange rate. When foreign exchange reserves fall below a critical level, a speculative attack occurs
because agents attempt to avoid suffering capital losses (or to achieve capital gains) in preparation of
collapse of the fixed exchange rate.4
These models argue that a speculative attack on the domestic currency can result from an
increasing current account deficit, which indicates an increase in the trade deficit and leads to a fiscal
deficit. According to Krugman (1979), a fixed exchange rate system is the unavoidable target of a
speculative attack which is a key assumption in the models. The government defends the exchange
rate peg with its foreign currency reserve. As agents change their portfolios from domestic to foreign
currency because of the fear due to growing fiscal deficit, the central bank must continue to exhaust
its reserve to stave off speculative attack. The crisis is triggered when agents expect the government
to abandon the peg. The central bank’s reserves fall to the critical level when a peg is no longer
sustainable and the exchange rate regime collapses.
The first-generation models help explain some of the fundamentals that cause currency
crises, but do not explain why the currency crises spread to other countries.
Obstfeld (1986) diagnosed that speculative attacks appear to be self-fulfilling since they may
occur “even when the level of reserves seems sufficient to handle normal balance-of-payment
deficits”. There exists circumstance in which crises may indeed be purely self-fulfilling events rather
than the inevitable result of unsustainable macroeconomic policies.
4
Krugman (1979: 324) stated that “a balance-of-payment problem – defined as a situation in which a country is gradually
loosing reserves – becomes a balance-of-payment crisis in which speculators attack the currency”, and “balance-of-payment
crises are a natural outcome of maximising behaviour by investors”.
132
2.2 Second-generation models
In 1992 and 1993, the Exchange Rate Mechanism of the European Monetary System (EMS)
suffered a huge speculative attack, which ended the mechanism, and led to the monetary union and its
common currency (see Eichengreen (2000)). The first-generation models, in which reserve loss
caused speculative attacks and devaluation, were challenged not to fit in explaining the EMS crisis
that culminated in the August 1993 widening of exchange rate bands within the EMS.
The EMS crisis and the following Mexican crisis of 1994-95 led to second-generation
models, developed by Obstfeld (1994) and Obstfeld (1996). According to the second-generation
models, speculative attacks are triggered by just the probability, rather than existence, of
inconsistencies in economic policies. In the EMS crisis that erupted in September 1992, reserve losses
certainly accompanied a crisis, but they were not the factor that triggered it nor the factor that
ultimately led the authorities to devalue (Obstfeld (1994)). Obstfeld (1996) noted that a “sunspot with
low ex ante probability” can have devastating effects in a world of incomplete markets and cause a
crisis.5 Highly indebted governments with mostly short-term or floating-rate nominal debts may
suffer from a speculative attack in expectations of depreciation, as seen in the 1994-95 Mexican
experience.6 A speculative attack forcing the devaluation of one country’s currency may make other
counties subject to crisis, which was to become one of explanations of the origins of the 1997 Asian
financial crisis.
In the second-generation models, government could fight speculation by using high interest
rate and/or selling international reserves, but prefer to let the exchange rate float to avoid the real cost
in terms of unemployment that could follow (Eichengreen, et al. (1996)). Faced by the speculative
attacks, the government decides whether to defend a fixed (or pegged) exchange rate considering
5
For more details, see Obstfelt (1996: 1044-1045).
In Mexico, as a large amount of short-term foreign currency linked debt (tesobonos) was coming to maturity and foreign
reserves were insufficient to service this debt, the risk of a self-fulfilling rollover crisis by investors’ panic became evident.

133
trade-off between the benefits of a strong currency and the costs of higher unemployment. This
endogenous policy response could trigger a crisis. The interaction between agents’ expectations and
actual policy outcomes leads to self-fulfilling crises.
The second-generation models also include the existence of multiple equilibria. There is a
“good” equilibrium where the markets do not attack the currency and the government’s preference is
to maintain the peg, which is possible since the fundamentals allow the survival of the regime.
Simultaneously, there exists a “bad” equilibrium where an attack, if it were to occur, would succeed.
These multiple equilibria exist because markets act on the basis of expectations of a particular
outcome. What makes a crisis occur is the belief that it can occur. Expectations that are ex ante
unjustified are validated ex post by the outcome that they have provoked, which Wyplosz (1998)
called “self-fulfilling”. In other words, there is more than one equilibrium that can be rationally
anticipated by economic agents, and in the presence of multiple equilibria, financial and currency
instability can be driven by sudden changes in agents’ coordination from one equilibrium to another,
given the economic fundamentals (Corsetti (1999)).
Two traditional views of currency crises discussed above provided the two main frameworks
in which to interpret cases of currency instability. The second-generation models of self-fulfilling
crisis developed by Maury Obstfelt have been favoured by a number of authors after the 1997 Asian
financial crisis.7
However, the two models seem to be insufficient to explain the 1997 Asian financial crisis,
although they provide a partial explanation of the crisis.
7
In fact, Krugman, organiser of the first-generation crisis models of fundamentalists stories, conceded: “I was wrong; Maury
Obstfelt was right” (see Krugman (1999)).
134
2.3 Alternative models on the financial crisis
The Asian crisis triggered by the devaluation of the Thai Baht in July 1997 inspired a new
kind of crisis model, called “third-generation crisis models”, as it did not conform to the first- and
second-generation crisis models to the extent that Krugman (1999) admitted the Asian crisis aroused
a “sense of humility” as well as a sense of vindication for the currency-crisis theorists. Due to the
complexity and specialties of the Asian crisis,8 there has not been an identifiable consensus on the
new models. Other than traditional indicators of the crises, various factors like moral hazard problem,
financial fragility and balance sheet implications have become to be considered in modelling the
crises.
One strand of third-generation models emphasises that the crises are driven by weaknesses in
the financial sector. These include a weakly supervised and regulated financial system; moral hazard;
and fixed exchange rates distorting external borrowing in the direction of short-term foreign currency
debt.
Ineffective prudential regulation and supervision over the financial sector, especially in the
process of capital market liberalisation, contributed to excessive borrowing from abroad and
increased the risk that temporary liquidity shortages will trigger full-fledged financial crisis (IMF
(1998), Pesenti and Tille (2000)).
Moral hazard as a result of implicit or explicit government guarantees encouraged overborrowing and excessive exposure to foreign exchange by financial institutions (see McKinnon and
Pill (1996) and Krugman (1998)). The essence of moral hazard is that, if things went wrong, agents
“rationally expect the government to step in and modify its course of action in order to bail out
troubled private firms” (Corsetti, et al. (1999a)). When visible losses led governments to withdraw

crisis-hit nations were largely microeconomic problems such as maturity/currency mismatches, moral hazard, excessive
leverage, etc.
135
their implicit guarantees, foreign creditors suddenly withdraw their loans from even solvent
borrowers and financial crisis erupt.
This financial fragility brought about self-fulfilling “international illiquidity” or a “financial
panic” on the part of international lenders (see Radelet and Sachs (1998), and Chang and Velasco
(1998)). Chang and Velasco (1999) attempted to build a model of financial sector illiquidity to
explain recent crises as the by-product of a bank run. Bank runs are a common feature of extreme
crises. During a bank run, depositors rush to withdraw their deposit due to self-fulfilling loss of
confidence.
In addition, new models have stressed the role of balance sheet imbalances deriving from
currency mismatches (see Krugman (1999), Cespedes, et al. (2000), Allen, et al. (2002) and Cavallo,
et al. (2002)). Large currency devaluation in the presence of foreign currency liabilities (“liability
dollarisation”) can increase the value of debt relative to revenues, crippling insufficiently hedged
debtors and leading to business failures. The third-generation models based on balance sheet analysis
were developed to understand how capital account movements lead to currency and financial crises
(see Dornbusch (2001)). Balance sheet issues are fundamentally linked to mismatches. In a mismatch
situation, exchange rate depreciation works in an unstable manner to increase the prospect of
insolvency and hence the urgency of capital flight.
Other contributions try to model the “sudden stop” and “capital inflow reversal” phenomenon
(Calvo (1998), Calvo and Reinhart (1999), Schneider and Tornell (2000) and Mendoza (2001)).
Sudden stop features an abrupt stop in foreign capital inflows and/or a sharp capital outflows with a
currency crisis.
A striking aspect of the crises in the 1990s was their speedy regional spread across countries.
The devaluation of the Thai baht in July 1997 was followed by currency crises in Malaysia and
Indonesia within a month and in Korea a few months later. This phenomenon is usually referred to as
136
“contagion”.9 More precisely, Kaminsky and Reinhart (2000) defined it as “a case where knowing
that there is a crisis elsewhere increases the probability of a crisis at home”. Although the
transmission of shocks can not be clarified by fundamentals (Forbes and Rigobon (2000)), various
explanations for the contagion across countries can be offered – common shocks, trade linkages,
financial interdependence and information asymmetries.
Common shocks can affect different countries similarly, which display similar elements of
domestic vulnerability. Some Asian countries shared common features such as a high reliance on
foreign-denominated debt and a relatively stable exchange rate against the US dollar (Pesenti and
Tille (2000)).
Contagion also spreads easily to countries which are closely tied by international trade
linkages (see Eichengreen, et al. (1996)). The currency devaluation by a country reduces the price of
its goods in foreign markets, leading to losing neighbouring country’s competitiveness and to
deteriorating its current account deficit.
Besides, different countries are financially interdependent if they borrow form the same
creditors. A currency crisis in a country reduces the ability of domestic borrowers to repay their loans
to foreign lenders. Foreign banks, faced with a large portion of non-performing loans, recall their
loans made to borrowers in other countries, causing credit crunch in those country.
Information asymmetries in financial markets give another explanation on the spreading of a
crisis. Financial globalisation reduces incentives for gathering and processing costly country-specific
information and thereby strengthens contagion (Calvo and Mendoza (2000)). Investors tend to
downplay national specificities and asymmetries, and consider several countries in a region as
substantially homogeneous. Under asymmetric information, as pointed out as herding behaviour by
Calvo (1999), “rational but imperfectly informed” investors can be triggered by signals emitted by

their contagious nature.

informed individuals. Set against the background of various explanations, next section examines the
Thai crisis to investigate which financial models can be applied to explain it.
3. The Thai Financial Crisis
The Thai abandonment of its currency peg in July 1997 drove the neighbouring countries into
a severe economic turmoil. Geographically, the countries hit by the crisis originating from the Thai
baht devaluation are mostly located in Southeast Asia while Korea belongs to Northeast Asia.10 This
section focuses on Thailand and covers the background and historical facts of the currency turbulence
in the Southeast Asian region.
3.1 Background
For years before the outbreak of the Asian crisis, the success of several Asian economies
created what has been called the “Asian Model” to be pursued by developing countries worldwide.
The economic success in Japan, the “four tigers” – Hong Kong, Korea, Singapore and
Taiwan – were followed by the three newly industrialised countries (NICs) of Southeast Asia –
Indonesia, Malaysia and Thailand.11 These eight high-performing Asian economies were the subject
of the World Bank’s report ‘The East Asian Miracle: Economic Growth and Public Policy’ (see
World Bank (1993)).12
These NICs constitute the Association of Southeast Asian Nations, or ASEAN, which was
established on 8 August 1967 in Bangkok by the five original Member Countries, namely, Indonesia,
10
The crisis is, therefore, often called the “East Asian (financial) crisis”, as seen in “The Onset of the East Asian Financial
Crisis” by Steven Radelet and Jeffrey Sachs (1998).
11
The three nations were called the “cubs of the tigers of Asia” – compared with four tigers - which had brought in the
"Asian miracle" that the former had succeeded in repeating (Jomo (1997)).
12
According to the report, the 23 economies in the region grew faster than all other regions and these eight countries have
grown at a rate more than twice as fast as the rest of East Asia since 1960.
138
Malaysia, Philippines, Singapore, and Thailand.13 The city-state Singapore was the first ASEAN
country to achieve the NICs status, while the other four member countries (hereafter referred to as
ASEAN-4) suffered severely from the financial crisis and their economies have yet to recover from
the shocks.
Table 2 provides the pre-crisis macroeconomic performance of the five ASEAN countries.
The data suggests that these economies had for a long time enjoyed strong fundamentals, including
high growth, high domestic savings, low inflation and healthy fiscal positions, while Thailand’s
current account deficits were relatively high.
The sustained vigour of the economies in the 1990s raised optimism that rapid growth would
continue indefinitely although the sustainability and efficiency of the growth was questioned by some
scholars such as Krugman (1994) and Young (1995). Capital inflows into the region were boosted by
decline in asset yields and lower interest rates and abundant liquidity in industrialised countries (see
Table 3 and Table 4).
Movements in exchange rates among the major currencies have been another significant
factor. Since Japan is central trading partner with ASEAN countries, any change in yen/dollar
exchange rate was bound to cause their trade performance. The ASEAN-4 had special exchange rate
arrangements entailing close links to the US dollar. When the US dollar continued to weaken against
the yen starting from the level of 130 yen in May 1992 until reaching an all time low 79.75 yen on 19
April 1995 (see Figure 1), it increased the competitiveness of the ASEAN-4 as their currencies
depreciated vis-à-vis the yen and eventually they had substantial gains in net exports and growth.
However, as shown in Figure 1, when this decline in the dollar was reversed over the two years
beginning in mid-1995, with the dollar recovering against the yen, the countries suffered substantial

139
losses in competitiveness, with adverse effects on net exports and growth. These developments led to
sharp slowdown in export revenues in these countries.
In the process of movements toward liberalisation and increasing competition without
prudential regulation in place and appropriate supervision over financial institutions, the fixed
exchange rate regime, along with the relatively high domestic interest rates, encouraged private
financial sector in Thailand to borrow from abroad in order to exploit the interest differential.14
Looming currency turmoil in Thailand caused by a string of speculative currency attacks led
to spill-over, though limited until then, into neighbouring ASEAN countries. The abandonment of
Thai exchange rate peg against the dollar and the implementation of the baht to float put the other
three countries under pressure to devalue and precipitated eventual huge loss in the value of their
currencies.
3.2 The Thai financial crisis
The Asian crisis of July 1997 has been said to arrive with little warning. However, Thailand
had shown a few warning signals ahead of full-fledged crisis.
The Thai baht had come under downward pressure in January and February 1997 due to
intensified concerns regarding the sustainability of the US dollar peg due to large current account
deficit, high short-term debt, the collapse of property price bubble and erosion of external
competitiveness.
Renewed pressures on the Thai baht in early May caused the central bank to intervene heavily in the
market, introducing capital and exchange controls and higher interest rates policy. These measures
failed to restore confidence in the currency.
Thai economy came to a crashing halt when increased speculative attacks on its currency
forced the abandonment of the peg on 2 July 1997 after enjoying a decade of the world’s highest

the Philippines, where it averaged 1.3 per cent of GDP (Radelet and Sachs (1998)).
140
economic growth. In fact, growth in real per capita income averaged 5 per cent each year and real
Gross Domestic Product (GDP) grew at about 9 per cent a year since 1986, but slowed down in 1996
(see Table 5).
From 1960 to 1996, annual economic growth in Thailand averaged nearly 8 per cent. In the
1960s, growth was led by strong public sector investments in infrastructure and by expanding private
investment in manufacturing, especially in import-substituting industries. The expansion of the
industrial sector was attributed to a number of favourable factors, including abundant supplies of
natural resources, labour, and economic and political stability. In addition, the government played a
strong role in promoting industrialisation, influenced by Keynesianism, the dominant economic
school before the 1970s.15 The Thai economy continued to expand at high rates in the seventies with
rapid expansion of manufactured exports, promoted by the third NESDP (1972-1976).
In the 1980s, Thailand faced economic difficulties with GDP growth averaging 5.6 per cent
from 1980 to 1985 in comparison with the average rate of nearly 8 per cent over the last decades,
following the two sharp oil crises and the resulting world recession of early 1980s.16 The crisis
originated in the finance companies, which were poorly supervised and had engaged in heavy
speculations in shares and real estate (see Alba, et al. (1999)).
15
The Thai government’s strong influence over the economy was reflected in the establishment of government economic
agencies, such as NESDB (National Economic and Social Development Board) for development strategies, MOF (Ministry
of Finance) for tax policies, MOC (Ministry of Commerce) for trade policies on agricultural and industrial products. Many
effective socio-economic plans formulated by these agencies included the five-year National Economic and Social
Development Plan (NESDP) introduced by NESDB in 1961. At present, the ninth plan (2002-2006) is in implementation. For
more information, see the website of the Royal Thai Government available at www.ThailandOutlook.com.
16
During economic recession period, 24 finance companies were closed; the current account deficit was 9 per cent of gross
domestic product (GDP); foreign debt was 19.5 per cent of the total value of exports. These problems brought about the
devaluation of the baht in 1984.
141
Thai economy was also greatly affected by the rapid movement in some of the world major
currencies. After the collapse of the Bretton Wood system, Thailand chose to continue pegging its
currency with the US dollar. As the US currency appreciated against other major currencies between
1978 and 1985, Thailand lost its competitiveness. The government was forced to devalue the
currency, the baht, by 1.7 per cent in April and 8.7 per cent in July 1981, and went on to abandon the
single-currency fixed exchange rate to the basket system in 1984, which amounted to an effective
devaluation against the US dollar by another 15 per cent (Ariff and Khalid (2000)).17
However, a dramatic turnaround emerged in the second half of the 1980s. Starting from 1986,
economic growth accelerated sharply, mainly due to increasing export resulting from the weak dollar,
foreign exchange income from tourism, and large inflows of foreign capital.18 The total inflow of
foreign investments in the last three years of the 1980s was equivalent to the total inflow of the
previous thirty years - from US$190 million in 1980 to US$ 1,105 million in 1988 (Shen (2001)).
Thai capital inflows accelerated averaged a remarkably high 10.3 per cent of GDP between 1990-96,
compared with 6.7 per cent in the Southeast Asian region (Radelet and Sachs (1998)).
The growth in demand for investment funds coincided with the decision of the Bank of
Thailand to liberalise Thailand’s financial system. In 1990, Thailand accepted the obligations under
Article VIII of the International Monetary Fund which required the lifting of all controls on all
foreign exchange transactions on the current account. The opening of the capital account was also
accelerated by the launching of the Bangkok International Banking Facility (BIBF) in 1993. BIBF,
17
The system of pegging the baht to the US dollar was replaced with a basket of currencies in 1984. The basket includes a
heavy reliance on the US dollar, the yen, the mark, the pound sterling, the Hong Kong dollar and the Malaysian ringgit, with
the US dollar having the maximum weight of 85 per cent. The weight of each currency in the basket is undisclosed and
depends on the relative importance of that currency in Thai trade flows (see Ariff and Khalid (2000: 211)).

It included two digit growth rates of 13 per cent, 12 per cent and 11 per cent in 1988, 1989 and 1990, respectively (Data:
Bank of Thailand).
142
which was established to allow the free movement of financial capital in and out of country,
expedited an influx of short-term loans, with a view to benefiting from the significantly high interest
rate in the country in comparison with that of developed economies (see Table 4 and 5).
The bulk of capital inflows came in the form of offshore borrowing by banks and private
corporations, which together averaged 7.6 per cent of GDP in the 1990s (Radelet and Sachs (1998)),
and the maturity structure of the debt was to a large extent on the short-term basis that had to be
repaid within one year. The country’s ratios of short-term debt/total debt, and short-term debt/reserves
reached 46 per cent and 107 per cent, respectively, by mid-1997 (Shen (2001)). Large capital inflows
went not only into manufacturing, but also into real estate or securities which contributed to forming
what was described as a “bubble economy” (see Jackson (1999) and Petprasert (2000)).19 In the
meantime, the country’s current deficit increased due to the adverse balance of trade and the
ballooning of its foreign debts.
Thailand was proud of its success in industrial development and export-oriented industries in
which the country employed a Promotion Protection Policy (PPP) to encourage the growth of
industries and the export of industrial goods. Table 6 shows the high percentage of industrial exports.
However, the Thai industrial exports required the high import content due to a lack of capital goods
and technology (Petprasert (2000)). Thailand had to import capital goods, raw materials, fuel, and
chemical products for manufacturing production. Petprasert (2000) stated that these account for 85
per cent of the total imports. The weak structure of Thai industry led to growing trade and current
account deficits. Table 7 reports growing Thai trade deficit up to the onset of the crisis.
19
From 1988 until the crisis, the price of land increased by 100 per cent to 200 per cent in a year. The stock market boom
encouraged a large number of middle-class Thais to become investors; many became rich within days. This condition is
termed by academics a "bubble economy", a condition in which asset prices increase rapidly because of speculation
(Petprasert (2000)). However, one third of the non-performing loans that crushed the financial sector came from investments
in property (Jackson (1999)).
143
The rise of the baht in value due to the strong dollar in the international markets caused Thai
exports to rise in price and become expensive. As Thai export products increased in price, they were
no longer competitive and consumers began to look for cheaper goods. Ensuing large current account
deficit led financial markets to consider its pegged exchange rate as unsustainable. However, in order
to keep the Thai economy favourable for foreign investment, the government chose to maintain a
pegged exchange rate regime. After a series of futile efforts to defend against speculative attacks on
the baht, the peg collapsed on 2 July 1997 losing soon lost 60 per cent of its value.20
During the economic boom, vast loans to large companies were made in US dollars not in the
baht, encouraged by the lower US interest rates and the baht being pegged to the dollar. Sudden fall in
the value of the baht deteriorated financial status of the companies, contributing to the huge nonperforming loans of the financial institutions, which owed their borrowings to foreign creditors.
A reckless build-up of currency and maturity mismatches by both the financial and corporate sector
made the nation vulnerable to a reversal in capital flows and devaluation in domestic currency, and
culminated in the crisis.
An inflexible exchange rate encouraged financial institutions and corporations to overborrow short-term funds from abroad without hedging, paying little attention to the risks involved.
The exchange rate peg to the US dollar increased the real value of the baht as the dollar's rise against
the yen started from the mid 1995 (see Figure 1), worsening a slow-down in export demand in 19951996, thus deepening the current account deficit over three years so that by July 1997 it had reached
an unsustainable 8 per cent of GDP (data from the Bank of Thailand).
Inadequate supervision of financial institutions and weak corporate governance created
incentives to invest in speculative ventures and real estate, creating the bubble economy. The
financial institutions made loans secured on the assets of borrowers without analysing their

productivity. When the bubble burst, the borrowers were not able to repay their borrowings, leading
to non-performing loan problem in the financial institutions.
In early March 1997, stock market prices in Thailand began to decline. In May the Thai baht
was attacked by the currency speculators. When the government defended the fixed exchange rate by
selling foreign currency, foreign currency reserves became depleted.21 On 2 July 1997, after spending
billions of US dollars on the defence of the baht, the Thai Central Bank was forced to let its currency
float.
On 28 July, finally, Thailand called in the IMF and received a rescue package of US$16
billion in terms that the Thai Government raise taxes, cut spending, and keep inflation below 4-5 per
cent. A comprehensive restructuring of the financial sector was also to be implemented (see the
Thailand Letter of Intent of the government dated 14 August 1997).
Explanation of the crisis
The economic structure in Thailand leading up to the Thai currency crisis was examined.
Thailand had enjoyed a long period of economic success until the outbreak of the crisis. However, the
growth of industries and high portion of industrial exports also contributed to rising trade deficits due
to scarce capital goods and technology. In the meantime, the country had accumulated its current
account deficits which had been unnoticed by market watchers due to the optimism. Short-term
capital inflows were huge, amounting to 7-10 per cent of GDP before the crisis while FDI was only 1
per cent of GDP, which were great concern compared with other nations in the Southeast Asian
region.
Realising the seriousness of the widening current account deficits and spiralling short-term
foreign debts, the market players began to sell the baht and buy the foreign currency in order to make
21

http://www.imf.org/external/np/loi/081497.htm).
145
a capital gain/avoid a capital loss in rational expectation that the Thai government could not maintain
the fixed exchange regime.
The first- and second-generation models of currency crisis were argued not to be sufficient to
explain the Asian financial crisis. When analysing the Thai crisis alone, however, the crisis was the
very example of the first-generation models, although some factors captured in the so-called thirdgeneration models were seen.
4. Conclusions
The economic theories of the crises in the literature have been examined. First-generation
models view crises as the unsustainable fiscal and monetary policies incompatible with a pegged
exchange regime, or fundamental imbalances. The second-generation crisis models, motivated by the
1992 EMS crisis, highlight self-fulfilling expectations and multiple equilibria, in which market
expectations directly influence policy decisions even in the absence of changes in fundamentals. The
Asian crisis generated a new kind of crisis models, so-called third-generation models, in which moral
hazard, financial fragility, balance sheet imbalances, contagion, etc. are captured.
The widening current account deficits and fixed exchange rate system brought speculative
currency attacks on the Thai currency and the ensuing devaluation of the baht devastated the private
sector, which accumulated huge foreign liabilities without hedging currency and maturity. A crisis in
Thailand spread to the other countries in the region with a contagious effect.
Investigation into the Thai crisis gives a good example of the first-generation models in that a
speculative attack on the baht resulted from an increasing current account deficit and the authorities
exhausted the foreign reserves to defend the fixed exchange rate system and eventually had no other
choice to abandon the currency peg, leading to a discrete depreciation of the currency.
In conclusion the Thai crisis was caused by poor fundamentals and was the expected
outcome of unsustainable policy stances incompatible with a pegged exchange regime, which is
characteristic of the first-generation models. A series of crisis in neighbouring countries after the Thai
146
crisis, which has become known as ‘the 1997 Asian financial crisis’, is rather accounted for by the
second-generation models or the third-generation models.
