Relevance of the study
The balance
of payments is one of the most important indicators for policy makers in open
economies, especially in countries where the stabilization program is
emphasized. What happens to a country's balance of payments becomes the focus
of attention.
In the
balance of payment, current account (CA) is an important item, because "the current account is what policy makers often refer to as
"intermediate target"; that is, a variable which is both a broad
reflection of the stance of macroeconomic policies and a source of information
about the behavior of economic agents" (Knight and
Scacciavillani,1998, p.4). Movement in the CA reflects all the actions and
expectations of market participants in an economy. There are two reasons for
that. Firstly, since CA reflects transactions between residents and
nonresidents of an economy on goods and services. Secondly, CA determines the
evolution over time of a country's stock of net claims on (or liabilities to) the
rest of the world. It reflects the savings and investments of domestic and
foreign residents. Therefore, the CA is an important macroeconomic variable and
we need to explain its movements, assess its sustainability, determine policies
to adjust it .
The
CA deficit or surplus mirrors the saving and investment behavior of the
domestic economy. Any change in country's CA position (e.g. a larger surplus or
smaller deficit) must necessarily be matched by increases in domestic savings
relative to investment or be financed by either liquidating foreign assets or
increasing liabilities to nonresidents. However, the current account deficit
can not be financed indefinitely by increasing foreign borrowing since doing so
leads to growing interest and amortization outflows making debt
unsustainable.
In the past
decades, many Asian countries have relied on foreign savings to accelerate
economic growth (Wong and Carranza, 1998, p.16). In addition to substantial
benefits, large capital inflows confront recipient countries with new
challenges that require careful management to ensure those benefits are
realized. Recent experience of Asian and Latin American countries clearly shows
that persistent large current account deficit may bring about sudden reversals
in capital flows and has spurred renewed interest in question of CA deficit
sustainability.
Since 1989,
Vietnam has transformed from an economy dominated by central planning to an
economy increasingly guided by market principles with high economic growth
fueled by foreign savings. High economic growth has been fueled by foreign
savings, so Vietnam witnesses persistent CA deficit.
The World
Bank (1997) recently concerns about Vietnam's CA deficit unsustainability and
structure of its less healthy financing. Whether the large deficit CA threatens
the country's external position is a central policy concern of the Vietnamese
Government. Therefore, close examination of Vietnam's CA deficit and the
factors underlying its long term development is necessary, especially in light
of the recent regional Asian crisis and its repercussions in markets throughout
the world.
2. Objectives and
Focus of the thesis
There are
few studies discussing the current account deficit sustainability so far. Fry
(1997) stated that Vietnam's double-digit CA deficit is sustainable in the
foreseeable future because it is financed almost entirely by foreign direct
investment. This conclusion needs more consideration because foreign investment
involves substantial loans at commercial terms (the State Bank of Vietnam).
Shishido (in IMF 1996) analyzed the structure of CA deficit financing and some
macroeconomic indicators. He concluded that the CA deficit of Vietnam was
sustainable. This conclusion also needs more consideration because since 1994
commercial loans have changed the size and pattern of Vietnam’s CA deficit
financing, especially in late 1997 and 1998, when FDI disbursements have gone
down due to the Asian crisis. Nguyen Thi Thanh Huong (1996) studied Vietnam's
external debt and CA deficit sustainability using Jaime De Pine's dynamic debt
model for the period of 1989-1994.
Huong reported a downward trend in the debt-to-export ratio that implied Vietnam's external debt
and CA deficit was sustainable. It also needs more consideration because variables
used in Jaime de Pine's model like
export and import growth rate, debt-to-export ratio and interest rate have
changed, especially when Vietnam has been impacted by Asian Crisis.
This thesis
attempts to assess the CA deficit sustainability of Vietnam in the 1989-1998
period that is still a central concern of Vietnam government. To obtain this
objective, the thesis analyses the evolution of CA deficit and analyses
comprehensively the capital account to find potential risks of running
persistent large CA deficit, then assesses its sustainability in relation with
debt sustainability. All these analyses focus on answering four research
questions for the case of Vietnam:
Q1. What
are the characteristics of the CA deficit?
Q2. In what
ways has the CA deficit been financed?
Q3. Has the
CA deficit been sustainable?
Q4. What
policies are advisable to manage CA deficit sustainability?
Typically,
the thesis specifies the maximum amount of imports called as warranted imports
that ensures CA sustainability during 1989-1998. Moreover, the thesis
introduces some scenarios of the CA deficit sustainability up to the year 2005
based on projections by the WB and the IMF to find warranted imports in each
year.
3. Research
Methodology of thesis
In view of
the fairly short experience in economic renovation, economic time-series for
Vietnam is not meaningful. That is why I do not intend to utilize econometric
for my thesis, but instead employ descriptive and comparative methods. For
assessing the current account deficit sustainability, the Jaime De pine's
dynamic debt model is used for
quantitative analysis.
4. The structure of
the thesis
The thesis
will be divided into four chapters, plus an introduction and conclusion. The first chapter is a literature review.
The second chapter surveys Vietnam's
economic development and then examines the evolution of the CA deficit
before and after 1989. Chapter 3 will investigate the current
account deficit as the savings and investment gap. The patterns of the CA deficit
financing are discussed to find out whether Vietnam faces the risks when
running the large and persistent CA deficit. Chapter 4 analyzes the current account deficit and debt
sustainability. In this chapter, Jaime De Pine's dynamic debt model is used to
analyze debt sustainability during 1989-1998. Then future scenarios for the
current account and debt sustainability of Vietnam over 1999-2005 are examined.
chapter 1
theoretical framework
I.
Definitions and concepts
Some
economists have argued that different definitions imply at different theories
of the current account. There are four different ways to describe or to
understand it. as follows:
Firstly, the current account measures
the economy's trade in goods and services with the rest of the world taking
into account all unilateral transfers including private remittances and
government transfers. Secondly, the
current account may be conceived as income minus absorption. Thirdly, the current account may be described as national savings
net of investment. Fouthly, the current account is seen as the change in net foreign assets with
respect to the rest of the world. The debate among the various schools of
thought has been generally fruitless, as all conceptualizations of the current
account are equally true and are linked together by accounting identities. The choice of concept
depends upon the purpose of the analysis being undertaken.
At
present, Vietnam has no legal document defining the CA and the balance of
payments. However, Vietnam has been measuring the balance of payments according
the fourth edition of the IMF
Balance of Payments Manual (1993). In terms of transactions accounting, the CA
of Vietnam consists of the balance on goods and services, net factor income
from abroad and net transfers from abroad.
In this
chapter, theories about the role of foreign savings in financing CA deficit
(section II), determinants of CA (section III), balance of payments adjustments
(section IV) and CA deficit sustainability (section V) are discussed. Following
is the different approaches to assess CA deficit sustainability and model used
in the thesis.
V. Sustainability of the Current account deficit and Jaime
De Pine's dynamic debt model
The first
approach relies on solvency condition. For an
economy to be solvent, the ratio of debt-to-GDP or export can not grow without
bound. It gives suggestion that an indebted country must keep ratio of
debt-to-GDP constant to ensure its solvency. In this context, sustainability of
CA deficit is insured if debt is sustainable. However, defining the
sustainablity of CA deficit by
measuring debt-to-export or GDP ratio have some shortcomings. Firstly, although
it provides a long-run condition for stability of the ratio of external
debt-to-GDP, it does not define whether that ratio appropriate or
"optimal". Secondly, one country with low level of debt wants to
accelerate high economic growth should not aim at keeping debt-to-GDP or
debt-to-export constant. It is not necessary that a country with high debt-to-export
or high debt-to-GDP make its debt
unsustainable. Because many countries have high debt-to-GDP ratio but they can
pay back while some countries have low debt-to-GDP ratio can not reimburse. Thirdly, solvency in this
context does not take unwillingness to lend on current terms in to account.
Some
economists argue that external crisis can occur because stock imbalance and
capital market factors like interest rate. These shortcomings call for a more
comprehensive set of capital account and financial indicators, in addition to
the CA. By this way, the sustainabilty of CA deficit is assessed not only by
solvency condition but also by external crisis riks involed in capital account.
The
difficulty faced by this approach is how to "rank" these indicators
and how to translate them to into an overall measure of CA deficit
sustainability.
It is relevant for me to analyze
solvency condition and more comprehensives of the capital account to find risks
of running CA deficit to examine the CA deficit sustainability of Vietnam.
There are some reasons for that. Firstly, although the CA deficit has been
financed mainly by FDI but FDI in
Vietnam involves a substantial amount of FDI-related loans. In fact, these
loans are borrowings from foreign countries at commercial term (the State Bank
of Vietnam). Indeed, the CA deficit has been financed mostly by external borrowings. Secondly, it is difficulty to
"rank" indicators in
second approach and to translate them to into an overall measure of CA deficit
sustainability.
To assess
Vietnam's solvency condition quatitatively, Jaime De Pine's Dynamic Debt Model
is used. Following is Jaime De Pine's Model.
Jaime
de pine's dynamic debt model
Based on
BOP identity, Jaime De Pine found the formula to calculate dynamic
debt-to-export ratio as follows:
(12)
According
to equation (12), the debt-to-export ratio (dt) is determined by two
parameters: the interest rate to exports ratio (a) and the growth rate of
import to export growth rate (b).
Two initial predetermined variables: initial debt-to-export ratio (do)
and initial import to export ratio or non-interest CA (vo). The
parameter (a) and (b) determines future evolution of debt-to-export ratio.
Jaime De Pine stated that if the
debt-to-export ratio are on upward trend, both debt and CA deficit are
unsustainable. Conversely, if debt-to-export ratios are on a downward trend,
the debt and CA deficit are sustainable and the debt country solvent.
Typically,
the Model emphasizes “excess import restraint” that is synonymous with
overadjustment. In this sense, the excess import restraint is different between
actual and warranted imports. Warranted
imports are the maximum amount of imports that make the debt-to-export ratio
decline. The concept of overadjustment can be used to ask how much imports can
grow while keeping the debtor solvent as well as its CA sustainability. It
measures the amount of extra credit or extra the CA deficit to finance imports that a debtor country could borrow and pay.
Chapter 2
the Evolution of the Current
account deficit
in Vietnam, 1989-1998
I.
the Economic background
Vietnam
has transited from a central planned economy to a market-oriented one in the
time that involved many changes in external environment. Both economic reforms
and changes in external economic environment have influenced substantially on
trade as well as external position of Vietnam. Highlighted achievements Vietnam
enjoyed in the past decades are high economic growth, moving from rice importer
to the world's second largest
exporter of rice...However, there are still some outstanding issues need to be
concerned. Among them, large CA deficit is center of policy concern in
macroeconomic management. Before assessing the CA deficit sustainability, it is
necessary to review briefly its evolution before 1989.
II. the Current account and
the external debt before 1989
Before
1989, domestic production only meets 80 to 90 percent of internal consumption,
so Vietnam had to rely fully on foreign savings to meet investment
requirements. At that time,
transactions on goods and services were mainly with CMEA, so financing sources
for CA deficit was borrowings mostly from non-convertible area. External
borrowings had played an important role in financing the CA deficit until 1988
because at that time FDI was discouraged. Since 1988, structure of the CA financing has changed with the emergence
of FDI. However, for the whole period of 1985-1989, both FDI and
the external borrowings have not been sufficient to finance the CA
deficit, the large source was come from arrears accumulation.
Iii the Current account
deficit in the 1989-1998 period
Vietnam's
external transactions have undergone dramatically since economic reform. The CA
deficit has reduced rapidly between 1989 and 1992 because traditional sources
of financing from the former Soviet Union dried up when new one has not been
found. Since 1993, Vietnam has found financing sources from countries other
than CMEA group to finance the CA deficit. From that year, the CA deficit has
widened year by year until 1996.
In 1997-1998, it was narrowed due to import restrictions and Asian crisis's
impacts on Vietnam economy.
Compared
with other Asian countries, Vietnam has run much larger CA deficit in term of
GDP. While the indicator of the CA deficit as percent of GDP is always used in
cross-country comparisons, it hidden quite a bit some important information about
characteristics of CA. Is the explanation for the deficit found in a trade deficit or in high interest payment on
foreign debt? and does a given CA deficit result from high investment level or
low savings? The answers for these two questions vary substantially across
countries. The following part is
investigation of the evolution of trade balance, service, net factor income as
well as transfers from abroad in Vietnam during 1989-1998.
1. The trade balance
Trade
balance changed by each period. In
1989-1992, the trade deficit was very modest, about USD 50 million
per year. Since 1993, trade deficit has been deteriorated until 1996 with
imports increasing more rapidly than exports and reached at alarming level
(13.7 percent of GDP). However, the deficit was lower in 1997 because from late
1996, Government took a number of import restrictions to dampen the pace of
import growth, then counter the trade and CA deficit. The argument here is that
when Vietnam is member of AFTA (and eventually WTO), significant trade
liberalization is committed, therefore, using import restrictions seem to be
not relevant in the coming years.
1.1.
Composition of Trade:
1.1.1.Export
composition :
Vietnam's
merchandise exports have been dominated by agricultural, natural resources and
industrial products confirming the background of Vietnam economy. Two
traditional items that occupied largest share in total export are crude oil and
rice. Since 1994, there was a significant shift in the export composition of
Vietnam. Exports of textile and
cloth have emerged and increased rapidly so they cached up with rice. From
1995, textiles have become second largest commodity after crude oil with
revenue of more than USD 1
billion. Besides above major exports, other goods such as rubber, coffee,
cashew nut... have increased substantially and some items have played an
important role in the world market.
1.1.2. Imports
composition
A large
part of import's payments spends on capital goods like machinery, equipment,
auxiliaries, material and fuel. These goods accounted for 80-90 percent of
total imports while consumer goods occupied only 10-17 percent. However, the
value of consumer goods may be under recorded because smuggle goods are
existing in Vietnam. An unofficial data
estimates that the value of smuggled goods through the borders with
China, Cambodia and Lao was 15
percent of total import value. This is not surprise because many kinds of
consumer goods from these countries came to domestic market like garments,
shoes...and they crowded out the domestic goods.
1.2.
Direction of trade
The most
significant change in Vietnam's trade partners since 1989 was a decline in the
importance of Former Soviet Union as a traditional trade partners and raise in
the share of Asian as well as other countries in total trade value. Trade
with Asian countries has increased
from over 60 percent during 1991-1994 to nearly 80 percent of total trade
during 1995-1998.
2. Non-factor services
The revenue
from non-factor services are mainly related to tourism, post, transportation,
insurance...During 1990-1995, this item had little surplus but since 1995, due
to rapid increase in imported goods, the payments for freight, insurance has
increased substantially. In term of shares in total export of goods and
services, non-factor services accounted for 18 percent in 1992, went to 27
percent in 1996 and stayed at over 20 percent in 1997-1998.
3. Net factor income
from abroad.
Investment
income has mainly come from interest on deposits of Vietnamese residents with
non resident banks. However, this value is very small because foreign assets of
Vietnam are not much. In contrary, payment of this item has increased steadily
in recent years as a result of
rising scheduled interest payments on external debt. Due to huge amount of
external debt, Vietnam has to pay interest on this debt about some hundred USD
per year. In addition, profit remittance has increased in the past years when
FDI projects have been implemented after some years. Both increases in interest
payments and profit remittance had made net factor income item negative.
4. Transfers
The size of
the CA deficit has been reduced by high positive net transfer. From small
surplus at USD 90 millions in 1991, this item jumped to USD 1,200 millions in
1996 and USD 885 millions and USD 1,122 millions in 1997, 1998 respectively and
contributed significantly to financing resources of the trade deficit.
The overall
picture of the CA in term of sub-items during 1989-1998 has been mentioned
above. It can be said that trend of the CA and the trade balance are the same
but the CA deficit has not closed to trade deficit because substantial changes
in non-factor services and net factor income from abroad as well as transfers.
Generally, except nearly balance in 1991-1992, the CA has been deficit
persistently. As mentioned in chapter 1, running the high CA deficit is not
necessary a bad thing. But how to manage it to ensure of sustainability. In
analyzing the balance of payments and in particularly, the sustainability of any
specific CA deficit situation, it is important to consider the capital flows
that are emphasized in new thinking about CA. Following part is investigation
the CA as savings gap and discuss on the pattern of the CA deficit financing,
1989-1998.
Chapter 3
The pattern of the current account
deficit financing in
Vietnam, 1989-1998
I. The Current account
deficit as savings and investment
gap
Among the
most pressing issues facing Asian countries is the large gap between savings and
investment or the large CA deficit. However, the same size of large CA deficit
expresses different behavior of savings and investment among countries. What
information hides behind the large persistent CA deficit in Vietnam during this
decade? Low savings or high investment?
1. Recent development
in savings and investment
While
Vietnam's savings are low, it still has reached high economic growth in the
past years. Robust output and export growth has been supported by investment
that has increased significantly since 1990. In 1998, investment dropped
sharply because FDI that contributed to increase domestic investment decreased
due to the Asian Crisis.
The level
of savings was very low compared with high investment, so the CA deficit has
been widened, especially it reached a peak of 11.8 percent of GDP in 1996. It
is similar between Vietnam and other Asian countries that the current account
deficit is large but savings and
investment of these countries are much higher than those of Vietnam. So in term
of savings and investment Vietnam is in situation that involves more risk than
above countries. If savings have not been fostered to meet the high investment
requirements, running large current account deficit may create burden of debt
and then threaten the economy in the future. Therefore, finding ways to change savings and investment
behavior should be focused. But what sector's savings and investment gap should
be center of policies?
2. Savings and
investment by government and non-government sector
Savings and
investment gap of a national economy aggregate those of different sectors in
economy (government and non-government or private sector). In Vietnam, both
sectors bring savings gap but private sector's savings gap is larger than that
of government sector. To ensure CA deficit sustainability over the medium term,
promoting private savings is required, particularly financial sector should be
developed, to improve the CA deficit or narrow the savings and investment gap.
II- the Pattern of the Current
account deficit financing in Vietnam, 1989-1998
Large
savings and investment gap or large CA deficit reflects the net capital
inflows. According to balance of payments accounting, net capital inflows are
recorded in capital account that is counterpart of deterioration of the CA
deficit.
When
Vietnam started to open its economy, savings gap required a surplus in the
capital account. However, due to the huge amount of capital inflows in terms of
FDI and external debt, the profit remittance and interest payments that have
increased over recent years. These outflows will increase in the coming years.
As a result, capital account
causes the deterioration of the CA in the future. Therefore, to manage
CA, the macroeconomics policy should deal directly with capital inflows.
1. Level of capital inflows
The net
capital inflows into Vietnam have increased very sharply since 1992 and reached
a peak in 1996. It is not surprised to the case of Vietnam because capital
tends to flow to region where potential investment return is high (typically to
high growth countries) and/or where the market mechanism has to begin to take
roots (Wong and Carraza, 1998). Nevertheless, large capital inflows involve
risk of external shocks. It is true for the case of Vietnam. In 1997-1998, due
to Asian crisis, FDI disbursements and commercial borrowings decreased
that induced lower economic
growth.
Since early
of this decade, Vietnam enjoys accessing to various types of foreign capital
inflows to finance the CA deficit (see Table 3.4). Table 3.4 shows that
averagely FDI (net) accounts for nearly 80 percent of capital requirements for financing the CA deficit during
1989-1998. Share of FDI in total CA financing source is much higher than that
in other ASEAN countries. Averagely medium and long-term loan (net) and
negative short-term loan (net) bring no surplus because Vietnam has to pay not
only principal on old debt but also new debt.

Data are taken from Appendix VI and author's calculation
In some years,
disbursements of medium and long-term loan are not enough to pay scheduled
amortization. Although net on
borrowings do not bring much surplus to finance CA deficit. This does not
explain the declining role of external borrowings in financing CA deficit
because disbursements of loans during this period have been increasingly and
Vietnam accumulates external debt continously.
Besides
thes sources, other sources such as use of Fund credit, arrears accumulation,
debt relief have been used to finance the CA deficit during 1989-1998. Total
financing sources are not only enough to cover the CA deficit but also bring in
an increase in international reserve,
about some hundred millions of
USD per year. This creates pressures on the monetary policies management
as well as exchange rate and choosing an optimal level of capital inflows
should be considered. Moreover, financing CA deficit by arrears accumulation
will erode the creditwothness of Vietnam in international market.
The level
of capital inflows only mentions the size of capital inflows comes into
Vietnam. The more important thing is that the same size of capital inflows may
have different cost and involve different risk depending on the composition of capital inflows
(combination of FDI, external borrowings). Following is the composition of
capital inflows of Vietnam in 1989-1998.
2. Composition of
capital inflows
2.1.
Foreign direct investments
Looking at
the size of FDI in total capital inflows, it can be said that composition of
capital inflows of Vietnam in 1989-1998 is very advantageous because FDI
accounted for largest part. However, it is early to give confirm statement like
that. For the precise evaluation, it is necessary to see cost of FDI, and its
linkages with CA.
2.1.1.Components of FDI
and its link with external debt.
According
to The Foreign Investment Law, total investment of one project includes at
least 30 percent of authorized capital that is contributed by both sides.
Vietnamese side usually contributes in form of land use. In fact, most of
licensed projects have minimum authorized capital. The rest is borrowings (may
borrow from omestic and foreign
creditors).
However,
seeking capital in domestic market is not easy because Vietnam is still in
shortage of capital situation. Almost joint ventures have to find sources from
their parent companies and other foreign creditors. As a result, FDI inflows in
Vietnam have recently involved a substantial loan (see figure 3.3) with high
interest rate compared with ODA interest rate. Therefore, FDI may allow
investors to repatriate earnings even low profitability of joint ventures. In
such situation, advantages of FDI may be eroded in the case of Vietnam.

Source:
Data are taken from Appendix VI
2.1.2. Foreign direct
investment and its link with the current account.
Since 1989,
FDI inflows have increased substantially that create a surplus in the capital
account. In some following years,
it put negative impacts on the CA. There are some seasons for that. With low
share in total exports and higher share in total imports, trade balance created by FDI sector accounted for
around 30 percent of total trade deficit of the economy. After some years
implemented in Vietnam, some projects have remitted their profit to their home
countries. These remittances have increased recently and accounted for more
than nearly a half of factor payment to abroad in 1998. Moreover, payments of
technical fees, copyright, payment royalties and interest payments of FDI
sector also increased.
In
short, FDI has put negative
impacts on the CA during 1989-1998 and also leads to increase of external
borrowings.
2.2.
External debt
In the past
years, loan from foreign countries has played an important role in financing
the CA deficit together with FDI. In the context of financing the CA deficit,
external borrowings are expressed in term of flow figure. However, loan coming in Vietnam year by year
will accumulate debt. The same stock of debt will cost differently and involve different risk depending
on composition of debt by maturity, type of loan, currency domination and at
different interest rate. Therefore, the following are discussion on these.
2.2.1 Debt by maturity
Although
new loan from CMEA group has no longer been committed, Vietnam still has huge
amount of outstanding debt in Transferable Rubles. This characteristic made
difficulty in measuring the debt burden because there were no official exchange
rate between Transferable Rubles and USD to convert these debt.
Long term
debt accounted for largest part (about 80-90 percent) while short-term
debt and use of Fund credit
occupied 10-20 percent during 1990-1997. Among other countries in the region,
Vietnam's short-term loan is the lowest and involves huge amount of L/C with
deferred payments. Low share of short-term debt implied that the CA deficit has
been financed by almost medium and long-term loan. Knight and Scacciavillani
(1998) stated that the sustainable CA is one that can be financed by long-term
capital flows. From this point of view, with small share of short-term debt,
Vietnam seems not to be threatened by the CA unsustainability in the past
years.
However,
risk of composition debt by maturity does not ensure sustainability, degree of
risk sharing with debt contracts also depends on the currency
denomination, interest rates, type
of loans.
2.2.2. Debt by
currency denomination
Debt
denominated in Transferable Rubles accounts for large part of total debt of Vietnam
despise it has downward trend along with increase in debt dominated in other
currencies. If the Transferable Rubbles debt is excluded, medium and long-term loan dominated in
USD accounts for almost of Vietnam's external debt. USD is the foreign currency
that Vietnam Dong is linked. Therefore, exchange rate risk will impact on
external debt of Vietnam. One point can be drawn is that when choosing
devaluation to adjust CA deficit it is necessary to consider the impacts of
devaluation on burden of debt, especially the debt services during the time
devaluation was made and then compare with benefit resulted from trade balance
improvement.
2.2.3. Debt by type of
loan (concessional and non-concessional loan)
Concessional loan over total debt is
very high, around 70-80 percent during 1994-1997. However, its share tends to
decrease since 1994 when commercial loans have increased. If Transferable Rubbles debt is excluded from
total debt, share of non-concessional debt has increased rapidly. Cost of
external borrowings to finance the CA deficit of Vietnam become more expensive
recently. Moreover, when non-concessional loan increase, it involves more
interest rate risk. Therefore,
Vietnam's external debt becomes more dependent on uncertainties in international
financial market. Considering interest rate become more important for external
debt management of Vietnam in the future.
It is one of important indicators will be taken into account in Jaime De Pine's dynamic debt model discussed in Chapter 4.
Managing
the composition of external debt is necessary to insure debt and CA deficit
sustainability. However, to ensure high economic growth as well as high export
growth rate fueled by foreign savings, one thing should be focused on is the
efficiency of capital utilization. The reason is that an increase in investment
does not automatically lead to higher economic growth. Hence, paying too much
attention to investment amount is not enough and capital utilization efficiency
should be concerned.
3. Capital utilization efficiency
Measuring
the efficiency of capital utilization by ICOR, Vietnam's productivity of
investment is comparatively high. However, ICOR of Vietnam in the past years
has not reflected fully an increase in efficient capital utilization. Vietnam's
recent growth has been characterized by increasingly capital-intensive
industrialization and by inefficient growing investment, low-return investments
(WB, 1997). Attracting huge amount of foreign capital but utilization of these
sources is not efficient create pressures balance of payments as well as on
capacity of paying debt obligation in the future.
Therefore,
the debt should be considered in relation with export growth. However, export
growth may not be enough to assess the sustainablity of debt and the CA deficit
because the important role of import growth rate was not be taken into account.
Moreover, change in international interest rate makes cost of financing CA
deficit different. Jaime de Pine's Dynamic Debt Model will take into account all
these factors. Let's move to the chapter 4 for analyzing the CA deficit and debt sustainability by that model.
Chapter 4
The current account deficit sustainability
and external debt sustainability
I.
Data base
The data of
external debt becomes a problem that needs to be considered because Vietnam's
external debt consists of two distinct components: its Transferable Rubles (TR)
debt and its hard currency debt. In term of original data, there were no
difference between data published by the World Bank, the IMF and Vietnam.
However, there are big difference among three sources of data due to different
exchange rates between USD and Transferable Ruble. WB uses the exchange rate of
USD1=0.56 TR, IMF uses the exchange rate of USD1 = 2.4TR while Vietnam expects
the exchange rate of USD 1=5.5 TR. Therefore, the WB databases show that
Vietnam is in severely indebtedness while IMF and Vietnam database show that
Vietnam's external debt is not severe. However, as mentioned in chapter 1,
these critical indicators are somehow arbitrary. The more important thing when
seeing external debt of one country is whether the country is solvent? It depends on its own capacity to
repay debt. In turn, repayment capacity depends on the export growth rate,
import growth rate as well as the change in international interest rate. All
these indicators are taken into account in Jaime De Pine' s debt dynamic model.
However, which database should be used
in analyzing CA deficit and debt sustainability by Jaime De Pine's Model? The most
relevant data used in this thesis
is the IMF data. There are some reasons for that.
·
The exchange rate used by World Bank is
the exchange rate used by CMEA members in batter trade. This exchange rate was
not regulated as the exchange rate for debt repayment.
·
Converting Transferable Ruble debt to USD
by the exchange rate of Transferable Rubles 0.56 against USD1 is not realistic.
·
Although exchange rate agreed between
Vietnam and some countries in CMEA is around Transferable Rubles 5.5 against
USD 1, the outstanding debt of Vietnam to these countries is very small.
Therefore, it is not sure that Soviet Union accept this exchange rate.
II. the Current account
deficit and Debt sustainability
analysis
1. The period of
1989-1998
Using a series
of economic indicators such as export and import growth, stock of debt,
interest rate on debt during 1989-1998 with base year of 1989, all variables
used in Jaime De Pine Model are calculated and simulated to find debt-to-export
ratio and import restraint at each year.
1.1. Debt-to-export
ratio, 1989-1998
Simulating
with (b) equal 1 and two above cases of (a), the trend of debt-to-export ratio
is indicated in Table 4.1.
Table 4.1
shows that the debt-to-exports declined rapidly, from 5 in early of this decade
to 2.09 in 1999. So the conclusion is that the CA deficit and the external debt
of Vietnam are sustainable in this period .
