ABSTRACT

With the development of financial market in Vietnam especially retail banking sector, bank
managers should have many strategies to keep customers stay with their banks longer. The
bank mangers focus on the loyalty of their customers because they know the revenue and cost
savings from the old customers are greater than from the attracting the new ones. Thus, bank
managers need to find solutions to impact the factors that influence customer loyalty to
compete with the other banks. This study focuses on two objectives: identifying the
determinants of customer loyalty in retail banking in Ho Chi Minh city, and based on the
results to give recommendations to improve the loyalty of state-owned banks’ customers, in
this case, it is Vietcombank. The qualitative and quantitative method will be applied to find
out the determinants of customer loyalty in retail banking. The findings of this research show

that factors which affect customer loyalty are Service Quality, Price and Switching Cost.
They
,

have strong influence on customer loyalty with the strongest impact factor is Price (beta
coefficient 0.583) and two factors Service Quality (beta coefficient 0.327), Switching Cost
(0.301). Based on the findings, recommendations for Vietcombank to improve customer
loyalty such as: diversifying distribution channels and service-products, different price
strategies for each kind of customers, some special program for VIP customers, etc.. .This
study only makes survey on 8 banks in HCMC, there are 2 state-owned banks (Vietcombank
and Agribank), 2 private-owned banks (ACB and VIBBank), 2 joint-venture banks (Indovina
Bank and Vid Public) and 2 foreign-owned banks (HSBC and Citibank). It should be widen to
more banks, big areas to increase the accuracy of the research. This study provides useful

information for future researchers who study customer loyalty in banking industry.

Keywords. Service quality, Price, switching cost, customer loyalty, retail banking.

CHAPTER I: INTRODUCTION

1.1 RESEARCH STATEMENT
From 1990 until now, number of banks increases highly especially private-owned banks and
foreign-owned bank branches, shows that attractive and potential development of Vietnam’s

banking industry for domestic and foreign investors. According to the data of State Bank of
Vietnam (SBV) until October 2009, Vietnam’s banking system has 3 state-owned banks, 40
private-owned banks, 5 joint-venture banks and 41 branches of foreign-owned bank. Vietnam

with population of 85 million people and increasing income is a potential market for
commercial banks. Moreover, many Government policies are issued to limit cash payment
in the public such as: pay salary through cards system, accepted banking documents in
deducting VAT, etc. .
Vietnam’s accession to the World Trade Organization (WTO) with their commitments of
financial services market’s liberalization and deregulation, their customers have more choice
between domestic and foreign banks. Furthermore, the customers access financial products

•

with no limitation, as a result, it affects to customer loyalty. In Vietnam, service market is
more and more improved and it is a new potential market for banks to explore. However, the

"

more increasing is personal income, the higher demands for products and services are.
Customers expect the higher quality of products and services than before. The higher
perceived service quality, the more satisfied and loyal the customers (Petruzzellis, D’
Uggento and Romanazzi, 2006). Beside the competing each other about the total assets
and market share (number of customers), efficiency in using the capital, ratio of bad debt,

banks always find out the customers' needs and supply at the right time to get the more

market share. They must try to offer attractive interest rates to both savers and borrowers,
which means that they must minimize their own internal operating costs and loss.
Nowadays, commercial banks have intend to develop retail sector, approach the individual
customers, small and medium enterprises (SMEs) because it is a large market and disperse
risks in banking business. Customers have opportunities to approach a lot of banks and choose
the best bank suitable to their own based on the price, service quality and convenience. In

2011, the competition is more and more heated when lots of commercial banks try to change
technology, reduce cost to strengthen competitive ability over the others. In this race, foreign-

1


owned banks have experience and strategy to expand their market in retail sector; private•

owned and joint-venture commercial banks always change in technology, service quality and
staff skills, is it state-owned commercial banks known as ‘to be hard to please’ have

competitive ability with trials or not?

CHAPTER II: LITERATURE REVIEW
This chapter presents an overview of customer’s loyalty and factors influencing on customer’s
loyalty in retail banking. This chapter also presents conceptual framework, hypotheses of this

study and measurement scales of factors of customer loyalty and its affected factors.

2.1 CUSTOMER LOYALTY
Service loyalty can be defined in the following way: “Service loyalty refers the degree to
which a customer exhibits repeat purchasing behavior from a service provider, possesses a
positive attitudinal disposition toward the provider, and consider using only this provider
when a need for this service arises” (cited in Caruana, 2002, p813).
According to Oliver (1999), ther• are foui stages of brand-loyalty such as: cognition, affect,
intentional and action loyalty. At the first stage-cognition, based on the information about
the brand that the customers collect, they are loyal to the brand. The next stage is affective
loyal, the customers have some positive attitudes toward a brand. When customers have
behavioral intention of purchasing, it is the intention phrase. The last stage is action

loyalty when customers change from intentions to actions.
Loyalty plays an important role in the competition of building successful relationships with
their customers in the competitive retail banking environment. According to Duncan and
Elliot (2002) showed that loyalty of customer takes an important part in contributing
earnings and profits of an organization. Nowadays, the financial institutions are in the
process of competition with globalization, a suitable customer loyalty program is necessary
for them to keep customers stay with their organizations. The banks always find many ways
to supply the most qualified services to satisfy the customers on the best way to get the
maximum profit and improve the comparative position over the trials. Some studies have
pointed out that profitability of banks is connected to customer retention (Garland, 2002;
Anderson, Fornell and Lehmann, 1994; Reichheld and Sasser, 1990). In real world, if one
business increases 5% loyal customers with satisfaction about his products and services,
profit will increase from 25% to 85%. Customer loyalty provides the banks with great
revenue and cost savings. Surveys show that it is up to five times as expensive to recruit

new customer as retain an existing customer (Morgan, 2007; Clemens, Reichheld and
Sasser. 1990). When most banks

4


provide nearly identical financial products and services, customers have attention to change
•

their behavior (Beckett, Hewer and Howcroft, 2000).

2.2 FACTORS AFFECT CUSTOMER LOYALTY
There are so many studies indicated factors influencing customer loyalty in many fields, in
banking field, the previous researches showed that customer loyalty is affected by factors
such as: service quality, price and switching cost.
2.2.1 Service Quality
Service quality is defined as an impression of customer about the overall and service
provision of an organization through the interactions between a customer and a service

provider (Bitner and Hubbert, 1994). There are many definitions of service quality, the
widely used one defines service quality as a measure of how well the service level
provided meets customer’s expectations or needs (Lewis and Mitchell, 1990; Dotchin and
Oakland, 1994a; Asubonteng et al., 1996; Wisniewski and Donnelly, 1996). Spathis,
Petridon and Glaveli (2004) developed the perceived service quality as the customer’s
attitude to evaluate the oveTall service provision. In the banking sector, Kamilia and
Jacques (2000) stated that perceived service quality is the difference between the
customer expectations and the perceived service provided by the bank.
Parasuraman et at (1988) clearly identified service quality into five dimensions through the
SERVQUAL model as follows:
•

Tangibles: Physical facilities, equipment and appearance of personnel.

•

Reliability: Ability to perform the promised service dependably and accurately.

•

Responsiveness: Willing to help customers and promote service.

•

Assurance: Knowledge and courtesy of employees and their ability to inspire trust
and confidence.

•

Empathy: Caring such as individualized attention which the employee provides for
its customers.

Tangibles relates to the effect of physical facility. equipment, personnel and communication
“

materials on customers; and reliability, responsiveness, assurance and empathy relate to
element of human intervention in the service delivery.

5


The five SERVQUAL dimensions of Parasuraman et at (1985, 1988, 1991) have been applied

•

in evaluating service quality. For example, Levesque and McDougall (1996) based on the
SERVQUAL model to find the determinants of customer satisfaction in the bank. Avkiran
(1994) also based on the SERVQUAL measurement to identify four dimensions including
17 items in the Australian retail banking industry, there are: staff conduct, credibility,
communication and access to teller services. Ennew and Bink (1996) developed three
banking service quality dimension in United Kingdom, they are: knowledge, advice
offered, personalization in the service delivery and general product characteristics.
It is very difficult for customers to evaluate services at pre-consumption, consumption and
post-consumption stage. Because of intangible nature of services, it is also difficult for
organizations to understand how its customers perceive and evaluate the quality of its
services. Service quality is a comparative function between consumer expectations and
actual service performance (Parasuraman et al., 1985). In the banking industry, there are two
types of perceived quality: (1) perceived quality product (tangible) is the assessment of

customer about the banks products and (2) perceived quality service (intangible) is the
assessment
•

toward service related to products such as: service in and after purchasing, advanced and
delivery condition. Both perceived products and services are important attributes of perceived
quality of retail banking. Today’s competition between organizations is comparing the
products and success of business is to have to deliver a diversified product to customers.
Easingwood and Storey (1995) showed that the important successful strategy is to introduce
new products successfully and service products related to technology can reduce transaction
costs, switching rate and encourage customers to create services outcomes on their own
(Bitner, Ostrom and Meuter, 2002). With intangible characteristics, perceived services of the
bank are lending condition, credit information, time to release a loan, manager and staff style,
transaction environment, etc.

With high service quality the firm will obtain a lot of advantages such as enhancing
reputation, increasing customer retention, attracting new customers through word-of-mouth,
creating competitive product difference and improving financing performance and
profitability (James 1998, Zeithaml et at., 1996; Julian and Ramaseshan, 1994). In the
banking sector, high service quality is always connected to customer loyalty. In an
investigation of Berggren and Dewar (1991) in United States found that 42% of customers
closed their accounts or switched to another bank as a result of service-related problem. In a


empirical evidence in Asian financial market (Islamic banks in Malaysia) of Dusuki and

•

Abdullal (2006) showed that service quality of Islamic banks contributes to customer
satisfaction and influences customer’s support for Islamic banking.
Service quality can affect customer’s behavior, especially factors related to service quality

-

such as: speed of delivery, efficiency, friendliness, frequent communication can increase
customer’s loyalty (Lewis and Soureli, 2006). Customer’s behavior can be determined by
service quality: loyalty will be raised depend on perceived higher standards of service
quality than their expectations, on the other hand, poor service quality leads to the higher
customer’s defection (Leed’s, 1992; Zeithaml et al, 1996). In the investigation of Mavri
and Loannou (2008) of customer’s switching behavior in Greek banking services, found

that there is positive relationship between good service quality and customer’s loyalty.
2.2.2 Price
According to Zeithaml (1998), price is an attribute that must be given up or sacrificed to
obtain certain kinds of products or service. In a research of Keaveny (1995) stated that

•

‘pricing’ factor involves prices, rates, fees, charges, surcharges, service charges, penalties,
price deals, coupons, and price promotions.
Madill and colleagues (2002) showed that there are some advantages for customers and
banks in their relationships: the final goal of banks is to maximize profit, improve financial
report with low risk, the customers want tc easily borrow money with suitable rate, etc..
Thus, the good relationships with customers bring a lot of advantages to banks such as:
reducing the switching rate of customers and increasing the number of new customers
through the recommendations of their current customers. In the financial service industry,
transaction cost has wider implications than other service industries such as bank
charges, interest rates charged and paid, fee implementation (Gerrard and Cunningham,
2004).
Price is an important factor that can effect on customer satisfaction and behavioral intentions
(Varki and Colgate, 2001). Some studies of Stewart (1998), Colgate et at (1996) and
Keaveny (1995) also showed that price has strong influence on the customer’s decision.
Especially in the banking sector, price has a wider implication, Gerrad and Cunningham
(2004) found that pricing seems to effect to customer loyalty of bank more than of other
services. In the study of Colgate and Hedge (2001) of customers’ switching behavior
determinants in Australia and
7


New Zealand, showed that price is the top switching determinant, followed by service failures
-

.

and denial of services.

Changing price can impact on customer’s behavior (Varki and Colgate, 2001). In a survey of
Keaveney (1995) found that about 30% customers had switched firms because of poor
service price perceptions. Martins and Monroe (1994) showed that customers are sensitive
to price, any price increasing can lead to switching actions of customers (Campell, 1999).
Gerrad and Cunningham (2004) suggested that price plays an important role in the
banking industry, influencing customers’ behavior compared with service failures and
inconvenience. The authors discussed that applying higher charges on customers or
increasing fees can lead to opposite effects such as switching behavior (leave the banks,
stop to use the bank services, etc). Moreover, Dawes (2004) showed that there is a
positive relationship between prices increases and defection rates in the banking industry.
Therefore, transaction cost and customer’s loyalty are in negative relationship.

2.2.3 Switching Cost
Switching cost is cost of changing suppliers including financial and non-financial cost
(Matthews and Murray, 2007). Lee and Cunningham (2001) showed that customer loyalty
can be affected not only by the cost of dealing with the service supplier but also by the
cost of switching to another supplier. There are many ways of categorizing switching
cost. For instance, Fornell (1992) divided switching costs into search costs, transaction
costs, learning cost, loyal customer discounts and emotional costs. Dick and Basu (1994)
also summarized switching costs into time costs, monetary costs and psychological
costs. Matthews and Murray (2007) summarized switching costs into three kinds:
procedural switching costs which including time and effort expenses related to evaluation
costs, training and setup; financial switching costs involving the loss of benefits and
financial resources, and relational switching costs associated with the loss of personal
relationship and with the mark that can generate emotional and psychological discomfort.
In the banking industry, Matthews and Murray (2007) showed switching cost is the cost
that the customers suffer since they wish to change the bank provider. Kiser (2002) showed
the switching cost for bank customers including the time necessary to open a new account,
close an old account, and inform to their partners about the new account information.

Many studies stated that there is relationship between switching cost and defection rate of
•

customers. Fornell (1992) showed that high switching cost can reduce switching rate of
customer and prevent switching behavior if switching cost is higher than the expected benefits

.

of changing service supplier (Lees and al., 2007). Colgate and Lang (2001) found that
switching cost takes an important role in decisions of customers to stay or not when
investigated the switching barriers in the New Zealand financial industry.

2.3 CONCEPTUAL FRAMEWORK AND HYPOTHESES
From the research objectives and literature review, the conceptual framework is presented in
Figure 2. 1 and hypotheses of customer loyalty are proposed as follows:

Hypothesis 1: In retail banking, Service Quality has positive impact on Customer loyalty
Hypothesis 2: In retail banking, Price has positive impact on Customer Loyalty.

Hypothesis 3: In retall banking, Switching Cost has positive impact on Customer loyalty.


2.4 ADJUSTMENT OF MEASUREMENT SCALES
-

In the previous researches, there are measurement scales of service quality, price and
switching cost, however, these scales have been adjusted to be suitable with retail banking
in Vietnam.
2.4.1 Service quality
According to Parasuraman et al (1988) showed 22 original scales of service quality of five

dimensions which have been revised and modified to suitable to this study.
•

Tangibles: the scale ‘operating hours that are convenient to all its customers’ will not
used in this research because all banks have the same opening hours, the scale
‘modern-looking equipment’, scale visually appealing of physical facilities’ and
scale ‘materials associated with the service’ will be combined into one scale
‘physical and materials are well supporting for bank transactions’

•

Responsiveness: the scale ‘employees are willing to help’ and scale ‘employees are
never too busy to respond to your request’ will be combined into one scale ‘staff of
banks make every effort to help customers to solve their problems’.

•

Assurance: The scale ‘behavior employees instills confidence in you’ and scale ‘feel

safe in transactions’ also will be combined into one scale I feel safe to have my bank
serviced at this bank’.

•

Empathy: The scale ‘employees who gives you personal attention’ is more
meaningful than the scale ‘gives you individual attention’.

The table below indicates the original items of Parasuraman et at (1988) and adjusted items
scale fit to this study:

2.4.3 Switching cost:
According to Jones et a1., (2000), switching cost scale will be revised and adjusted to
suitable with this research:
•

The scale ‘inconvenient for me to switch to another service’ is not clear and difficult
to understand so it will be replaced by scale I don’t want to move to further
location’.

•

The scale ‘take a lot of time and effort to change to another company’ and scale ‘the
costs in time, money and effort to switch to another company’ will be combined into

•

one scale ‘take a lot of time to change to another bank’.
