Performing ADF Test for VAR model, all variables VNGOLD, INTERGOLD,
FRES, INTEREST, VNCPI, VCBXRATE all stop at the first level difference with
significance level of 1%. Therefore, according to Sim, C.A (1980), the above variables can
be used in the VAR model.
(ii) Choose lag in VAR model
The results show that the FPE, AIC, SC, and HQ tests all give a lag of 1, while the
LR test is 5. Therefore, the author chooses the optimal lag of 1 for the VAR model of phase
1 (due to have more statistical test numbers).
The results show that the FPE SC and HQ tests all give lag of 0, and LR and AIC
tests are 6. Empirically, any policy has a certain lag, so the study continues. Use the
Portmanteau test to determine the optimal lag. Portmanteau test for VAR model shows
that the optimal level of VAR 2 stage model is 1. Therefore, the study will use VAR 2
phase model with an optimal lag of 1.

policy of gold market and capital control activities in
China
1.3.2. State management policy for gold market in India
1.3.2.1. Infrastructure regulates the gold market in India
Due to its special role to the economy, the Indian gold market is very well segmented
by regulatory agencies with different functions and tasks. The Reserve Bank of India (RBI),
as a monetary regulator, regulates and oversees the financial system, plays a dominant role
in the gold market.
1.3.2.2. Gold import and export activities in India
1.3.2.3. Tax structure for gold in India
1.3.3. Lessons learned for Vietnam
From the case studies of state management practices for the gold market of China
and India, both have confirmed the importance and spread the role of state management to
the gold market. Every gold market contains certain risks related to the specific market of
each country, so the issue of state management for the gold market is always placed
urgently, regardless of size or market level. Where is the school? Especially, the gold
markets are still in its infancy and in the context of macroeconomic fluctuations, it is
necessary to follow and strengthen the role of state management.
1.4. Study Overview
1.4.1. Foreign studies on the gold market
- Qualitative research on gold market structure: Gary O’Callaghan (1993)
introduced and analyzed in detail the structural diversity of the gold market, Y.V. Reddy
(1997). The research paper on the change of gold management policy of the Central Bank of
India Sun Zhaoxue (2011) has pointed out the relationship between the gold market and the
health of the economy, while also giving an overview of gold industry in China. Which
7
highlights the role, mission of developing the gold market, the way to organize in
accordance with the goals.
- Research on the operation mechanism of the gold market: Alberto (1983)
provided a complete description of the gold function in the Jamaica system. Baur and
McDermott (2010) examined the role of gold in the financial system and considered gold
more stable in terms of returns than stocks, bonds, and other financial instruments.
- Macro factors affecting gold price
Interest rate: Harmston (1998) studied data on US Treasury bills and long-term
government bonds from 1896 to 1996 and showed a negative correlation between gold price
trends and the value of Other long-term bonds.
USD exchange rate and index: Sjaastad (2008) investigated the theoretical and empirical
relationship between important exchange rates such as USD, Pound, Japanese Yen and gold
using the wrong forecast data. and argue that fluctuations in exchange rates between
currencies are the main causes of instability in gold prices.
Inflation: Sherman (1983) holds that gold prices are positively correlated with the level of
inflation, regardless of the existence of expected inflation. Ranson and Wainwright (2005)
think that gold price is an indicator of inflation and the bond market, and it can act as a
predictor of inflation, short and long term nominal interest rates.
Geopolitical events: Barkoulas (2008) pointed out that in an extraordinary geopolitical
event, in the short term, the price of gold increases while the price of gold mining
companies declines.
Other factors: Malliaris et al. (2009) used an ANN-a neural network to collect data on
gold, oil and the euro from January 4, 2000 to December 31, 2007. Results of time series
analysis indicate that there is a short-term and long-term relationship: oil changes in prices
of gold, euro and oil have a strong impact on gold prices; The relationship between gold and
the euro is the weakest.
- Studying the international monetary properties of gold: Cohen (1971) defined
gold as an international currency from the perspective of monetary functions; The function
of international currency is to expand the domestic monetary function abroad. Tavlas (1997)
states that when gold is a currency that acts as a measure of value, a means of exchanging
and storing value in international transactions without the participation of currency issuers,
that creates monetary internationalization.
- Research on the impact of monetary policy on gold price: William D. Lastrapes,
George Selgin (1995a) pointed out a positive gold price shock that caused the gold price to
increase by 2% due to the effect of a gradual increase in the fund rate. The federal nearly 10
basis points after about 12 months, and gradually reduced foreign exchange reserves. These
findings imply that the average Fed actually changes its foreign exchange reserves in
8
response to a change in gold prices, though mostly after this change is maintained for
several months.
1.4.2. National research
Nguyen Van Anh (2009) With the study "Solution to improve the efficiency of gold
business management according to the functions of the Central Bank", the author pointed
out that "gold in foreign exchange reserves is gold plays a monetary role. At the same time,
the central banks of all countries have gold management policies through the management
of gold belonging to the national foreign exchange reserves and management of the
domestic gold market”. Nguyen Duc Trung (2012) With the study "Solution to manage gold
market in Vietnam" for the first time, using econometrics applied to analyzing objectives
and tools of SBV regulating gold market in Vietnam in period from 2006 to 2013. The
model used is VAR model including 5 variables: domestic gold price, international gold
price, inflation, exchange rate, foreign exchange reserves. Research shows that inflation,
exchange rates, foreign exchange reserves all have an impact on domestic gold prices. The
author pointed out that the gold management policy of the SBV basically affects the market
structure, positively affects the foreign exchange market, and monetary policy. Bui Kim
Yen and Nguyen Khanh Hoang (2013) with the research topic "Management of gold prices
from a macroeconomic perspective". Research using econometrics as a VAR model for
domestic gold prices, world gold prices, deposit rates, exchange rates and inflation to make
comments on the SBV's gold market state management policy. The study shows the
relationship between the deposit interest rate, exchange rate and inflation variables with
domestic gold prices in the 10-year period from August 2003 to July 2013. Thereby
assessing the positive effects of the State Bank's gold market management policy. Nguyen
Thi Thanh Huyen (2015) with her PhD thesis "State management of gold trading activities
in Vietnam". This is a systematic study on state management of gold trading, in which the
author uses the method of sociological investigation with questionnaires. The paper has
systematized the contents of internal management of the state, and at the same time gave the
system of criteria to evaluate the perfection of the state management policy of gold trading.
Tô Anh Dương (2009) with the study "Gold market management: International experience
and policy recommendations for Vietnam". Through practical surveys of two markets, China
and India, the author gave the experience of state management to the gold market in
Vietnam as: (i) Managing on the basis of respect for market principles, supply laws The
SBV's management objective is to make the optimal use of this resource. Use gold resources
for stable economic development. (ii) Promote the concept of market liberalization, the
roadmap should be consistent with the general trend. Do Thi Thuy (2010) with the research
paper "Vietnam Gold Market 2010 - Impacts on financial policies and operations of
commercial banks", Through assessing the impact of macro variables such as exchange
9
rates, inflation to gold price and surveying activities of commercial banks, the study offers
policy implications. Tran Ngoc Tho (2014) with the research paper "Managing the gold
market: The Mission of the State Bank", the research shows that gold is money (ultimate
money). Therefore, gold market management is a tool of monetary policy to manage money
supply. At the same time, by settling the gold position, bringing the gold to the balance
sheet of commercial banks, it has contributed to stabilizing the macro economy.
1.2. Research gap
From the above summary, the thesis finds that there is still a gap that needs to be
supplemented and completed as follows: The domestic and foreign studies have studied
only a part of the aspect of the price of gold, gold trading activities, State management with
gold trading activities. However, the systematic study of state management of the gold
market on the level of gold as a financial asset is a research gap. In which, the management
of the gold market is closely linked with the implementation of monetary policy. Empirical
research in different countries will yield different results. The thesis will approach towards
systematizing monetary policy impacts on gold market state management policies, building
a VAR model including many macroeconomic variables based on economic theories and
drama. from external shocks and from state management policies to the gold market by
month. Quantifying this relationship in the model will be a highly practical applied research
direction. The thesis will analyze the impact of external shocks and state management
policies on the domestic gold market through macroeconomic variables such as interest
rates, exchange rates, inflation and national foreign exchange reserves. Data analyzed by
month, from the results of empirical research, the thesis will propose a number of related
solutions to complete the state management policy for the gold market in Vietnam.
CHAPTER 2 - CURRNENT SITUATION OF STATE MANAGEMENT OF
GOLD MARKET IN VIETNAM
2.1. Practical gold market in Vietnam
2.1.1. Overview
In Vietnam during a long period of war and political instability, gold was used as a
traditional saving mechanism and even used as a means of payment and price standard for
trading valuable assets. The state management of the gold market has always had an organic
relationship with the operation of monetary policy in Vietnam due to its binding on both
laws and mechanisms.
2.1.2. The period from before 2006 - The gold market started to be under control
In 1999, the Government issued Decree No. 174/1999/ND-CP to expand business
activities in the gold market. In 2004, in order to contribute to macroeconomic stability and
to support exports, the SBV adjusted lower the VND / USD exchange rate, narrowing the
10
difference between the exchange rates listed at commercial banks and exchange rates on the
free market. Credit growth is estimated at 29% a year on average. Immediately, the
domestic gold market was supported to create momentum for expansion of both scale and
structure.
2.1.3. From 2006 to 2009 - Booming gold market
During this period, the domestic gold market continued to fluctuate, always
growing hot with an explosion of gold trading units with production functions. Beginning
in 2007, Vietnamese commercial banks launched a new type of business, the Gold
Exchange. In this period, in order to control inflation, the SBV implemented monetary
policy tightened. Vietnamese commercial banks immediately turned to gold trading on
their accounts after the SBV tightened lending criteria for traditional commercial lending
activities of commercial banks. The price of gold has been constantly increasing, coupled
with the long-standing preference of hoarding gold that people have been buying gold.
Increasing domestic demand for gold has created a high margin between domestic and
world gold prices, putting pressure on USD demand to serve gold imports. This situation
lasted for a long time, causing psychological confusion for people.
2.1.4. Period from 2010 - now: The SBV controls the gold market with
administrative tools, associating the State management with the goal of stabilizing
the macro economy.
The gold market witnessed a boom of the market in 2009, but behind the picture
there are potential uncertainties as the state management has not kept pace with the
development of the market. On December 30, 2009, the Government issued an instruction
order 369/TB-VPCP for the closing of all gold trading floors with a deadline of March 30,
2010. In April 2011, the State Bank issued Circular 11/2011/ TT-NHNN with the main
content being that the SBV prohibited commercial banks from lending gold or accepting
deposits in gold (called "gold mobilization") to any individual, organization. Decree
24/2012/ND-CP specifically banned gold bars as a means of payment / intermediary
exchange, the State switched to exclusive production of gold bars, this is the only unit
allowed to import and export raw gold. In the case of gold, gold bar trading may only be
carried out by licensed entities. The SBV holds gold as part of the official list of foreign
reserves.
2.2. Analyze the status of gold market
2.2.1. The situation of fluctuations between domestic and international gold prices
Since 2012, there has been a clear contraction of the fluctuation range of domestic
and international gold prices. By resolute measures and efforts through the SBV's impact
process, the domestic gold price was more stable before the fluctuations of international
gold prices, thereby stabilizing the market.
11
2.2.2. The continuity of the gold market and the foreign exchange market
When the SBV issued Decree 24/2012/ND-CP the correlation between gold price
index and USD has changed, the correlation is not as clear as the previous period. Therefore,
it is partly possible to see the effect of the SBV's policy on controlling the gold market.
2.2.3. Difference between domestic and international gold prices
The temporary suspension of interconnecting the domestic gold market with
international instruments is a mandatory and prudent step to ensure the monetary security
and internal health of the economy against changes. The continuous and regular nature of
the international gold price. There exists a margin of difference between domestic and
international gold prices as a result and due to a number of specific reasons as follows:
2.2.3.1. Imbalance between supply and demand for domestic gold
2.2.3.2. High volatility of international gold prices
2.3. Evaluation of State management measures for the gold market by the SBV
2.3.1. State management goal for the gold market of the SBV
Firstly, enhance prevent goldization comprehensively. Second, control the supply of
gold bars to the market consistently. Thirdly, stabilizing the domestic gold market is closely
linked to macroeconomic stability..
2.3.2. Positive aspects of the policy
2.3.2.1. The policy of ending mobilization and lending of gold in credit institutions
The SBV showed initial orientations for credit institutions in mobilizing and
borrowing capital in gold in a tightened direction. This move by the SBV has created a
timely reduction of the system's liquidity at the end of 2012, maintaining the necessary
stability for gold prices. At the same time combining gold bidding methods for commercial
banks to settle the gold status, the SBV achieved two parallel goals at the same time: to
ensure a stable gold price and gold market; gold is completely excluded from the two debt
assets and creditors of commercial banks.
2.3.2.2. Policy on management of gold trading and production activities
With the highest determination in state management of gold trading activities in a
tighter and more disciplined manner, the Government issued Decree 24. The Decree also
made a great impact on market sentiment, falling gold prices but people People did not buy
gold but continued to wait for more information of the market, especially speculation
sentiment nearly disappeared.
2.3.2.3. Measures against goldization
Firstly, improve the effectiveness of monetary policy management by the SBV.
Second, help stabilize the forex market.
2.3.2.4. Measures to stabilize the gold market
- The SBV has created a funnel mechanism in concentrating resources to reinvest in the
12
economy. Unifying a gold brand to help identify easily and ensure the rights of people. At
the same time, the SBV easily controlled the quality of gold bars in circulation.
- The role of market stabilization is strictly and thoroughly implemented by the Government
and SBV.
2.3.3. Limitations need to be overcome
2.3.3.1. Restrictions in identifying goals, planning strategies for gold market development
Firstly, the state management agencies do not have a long-term vision for the gold
market, leading to policy formulation that is always slower than the market development
process. Secondly, the SBV's regulations are all dealing with specific situations without
specific provisions defining the Gold Market Development Strategy or the Gold Market
Development Scheme.
2.3.3.2. Restrictions in the legal framework governing the gold market
Firstly, the SBV has not issued any regulations related to overall planning, detailed
design and construction of the gold market. Secondly, a number of state management
policies on the gold market are lacking in comprehensiveness. Third, the legal regulations
on gold market activities are not consistent with other laws. Fourth, the stability of state
management policy of the gold market is not high.
2.3.3.3. Restrictions in organizational structure of state management of gold market
Firstly, the apparatus of State management of the gold market in Vietnam is a
product that can handle the subjective situation of managers, but not really derived from the
development function of the gold market. Secondly, not in line with international practices,
all have formed a specialized agency, independently managing the gold market, thus partly
reducing the independence and flexibility in managing the gold market. Thirdly, the
organization of the state management apparatus for the gold market is still in favor of the
state administrative organization organized by the SBV.
2.3.3.4. Restrictions on policies and tools for State management of the gold market
Firstly, the system of policies and tools is still inconsistent, many aspects are limited.
Secondly, instrumental policies cause financial repression, affecting the stability of policies
and causing distinctions of business entities in the market.
2.3.3.5. Policy on managing gold bar business activities
Firstly, the openness and transparency of regulations on the gold bullion bidding
process, the announcement of the bidding results, and the announcement that the volume of
gold bullion purchases and sales of the SBV is not high. Second, policies to mobilize gold
reserves among the people have not been effective.
2.3.3.6. Tax policies governing gold trading activities
Firstly, in fact, the feasibility and effectiveness of VAT calculation by the method of
direct VAT calculation with the same tax rate is applicable to a mixed business
13
establishment which has just conducted business activities. Gold trading has not had high
gold production yet. Second, SCT for gold trading has not yet shown its role as a guiding
tool.
2.3.3.7. Gold smuggling problem
In fact, the problem of gold smuggling is always a historical issue in Vietnam, when
the official channels of gold import are limited, there will be unofficial channels of unofficial
channels, these channels exist very diverse form.
CHAPTER 3: MODEL FOR ASSESSING THE IMPACT OF STATE
MANAGEMENT POLICIES ON THE GOLD MARKET WITH MACRO
ECONOMIC VARIATIONS
3.1. Research design
3.1.1. Research models
Inheriting the views of the views of other models, the author chooses 6 variables:
Domestic gold price, International gold price, National foreign exchange reserve, Average
deposit interest rate under 12 months of Vietcombank, USD / VND exchange rate of
Vietcombank, Inflation Vietnam (CPI). The variables of the model are converted into a first
order difference of natural logarithms instead of being absolute values.
3.1.2. Study samples, research data and analytical methods
The observed sample consists of 132 observations (11 * 12 months) from January 2006 to
December 2016, the variables VNGOLD, INTERGOLD, INTEREST, VCBXRATE were taken
averagely monthly, VNCPI, FRES variables were taken according to month. The price analysis of
data splits into 2 phases from January 2006 to the effective date of Decree 24 (April 2012) and the
period since Decree 24 was officially implemented, the SBV officially tightened management.
gold market management in May 2012 to 12/2016 to clarify the relationship between exchange
rates and gold prices in these two sections. The dissertation uses the VAR - Vector
Autoregression to analyze the impact of state management policies of the gold market. The
EVIEW9 software is used for analysis of the above model.
System of estimated equations
The estimated model consists of a system of equations as follows:
GOLDVNt = α1 + +
+ + +
+ ε1t
k: Hysteresis value
14
α, γ, , , ε : square coefficient matrix of the equation
3.3. Results of running the model and discussion
3.3.1. Stationary test and lag in model
(i) Stationary test
Performing ADF Test for VAR model, all variables VNGOLD, INTERGOLD,
FRES, INTEREST, VNCPI, VCBXRATE all stop at the first level difference with
significance level of 1%. Therefore, according to Sim, C.A (1980), the above variables can
be used in the VAR model.
(ii) Choose lag in VAR model
The results show that the FPE, AIC, SC, and HQ tests all give a lag of 1, while the
LR test is 5. Therefore, the author chooses the optimal lag of 1 for the VAR model of phase
1 (due to have more statistical test numbers).
The results show that the FPE SC and HQ tests all give lag of 0, and LR and AIC
tests are 6. Empirically, any policy has a certain lag, so the study continues. Use the
Portmanteau test to determine the optimal lag. Portmanteau test for VAR model shows
that the optimal level of VAR 2 stage model is 1. Therefore, the study will use VAR 2
phase model with an optimal lag of 1.
3.3.2. Test autocorrelation of the residuals and stationary of model
(i) Test autocorrelation of the residuals
We have a phase 1 VAR model with lag of 1 with no autocorrelation.
We have a phase 2 VAR model with lag of 1 with no autocorrelation.
(ii) Test stationary of model
Using the AR ROOT TEST test, we have both the VAR model of 2 stages 1 and 2 with
lag of 1 which has passed the basic tests so it can be applied in analysis and forecasting.
3.3.3. Impulse-Response analysis result
(i) Relationship between exchange rates and domestic and international gold prices
- Impulse-Response function between VCBXRATE and VNGOLD, INTERGOLD of
VAR model phase 1
15
The results of the reaction show that before the issuance of Decree 24/2012 / ND-CP
on gold business management, at the time of the domestic gold price increase shock with a
magnitude of one standard deviation. Vietcombank's selling rate also increased by 0.2%,
international gold price increased by 1 standard deviation, Vietcombank's selling rate
increased by 0.5%.
- Impulse-Response function between VCBXRATE and VNGOLD, INTERGOLD of
VAR model phase 2
In contrast, the results of the Impulse-Response in the picture above show that after
the issuance of Decree 24, the exchange rate turned back when there was a shock of gold
price increase. The relationship during the period from May 2012 to December 2016 was
that the domestic gold price increased by 1 standard deviation, the selling rate of
Vietcombank decreased by 0.10% after 1 month and quickly balanced again in When the
international gold price increased by 1 standard deviation, Vietcombank's exchange rate
decreased by about 0.03%, but the reaction occurred at the time when the gold price
increased (without delay). This proves that the relation between the exchange rate and the
world gold price after Decree 24 is the negative relationship and the reaction of the
exchange rate with the world gold price faster than domestic gold price. Thus, the
application of Decree 24 has changed the nature and direction of the relationship between
exchange rates and domestic (international) gold prices..
Phase 1
Phase 2
16
(ii) Relation between CPI and domestic gold price
Phase 1
Phase 2
When there is a shock about gold price, the CPI does not change immediately but it
will tend to peak at 2 months, then decrease gradually within 6-7 months. However, in
phase 2, the fluctuatio
