Abstract—The present paper gives a new perspective on the
banking risks and on their influences on the banking sector as a
whole. Due to the actual financial crisis, the banks are facing
more and more complex risks, with difficult to measure and
manage impacts. Among these risks, the one coming from their
inside structure were depicted and analyzed in the paper. The
main aim of the research is to find whether there is a strong
relation between the identified categories of risks and banks
evolution and in an affirmative case to see if this relation depends
also on the banking sector. For this, a powerful grey theory tool
was used, namely the GRA (grey relational analysis). Also, a case
study was considered for a number of 16 banks spread in 4
groups based on the banking sector they belong to. The results
were concluding as it can be seen.
Keywords— grey theory, grey relational analysis, risk,
management, banking sector, rating, modeling
I. INTRODUCTION
In history are known several turbulent episodes, of which
the most remarkable are: the tulip mania, the South Sea Bubble,
the great crisis of 1929, the financial crisis from October 1987
and the latest financial crisis that broke out in 2007, continued
in 2008 and 2009 and in some states existing at present.
The financial crisis started in 2007 due to the reckless
mortgage loans, is still an acute problem, despite the efforts
submitted by governments, World Bank and central banks.
Among the effects that this crisis has generated it can be
mentioned: fluctuations on financial markets, solvency and
liquidity problems of banks, lack of confidence of economic
agents, harsh policies for granting credit. The main measure
taken by the banks was to stop lending and trying to maximize
their profit.
Since it is impossible to know exactly how and when
financial crises will occur in the future, it is important for the
authorities not to neglect the changes that appear, but rather to
take action in real time, and to adopt flexible policies. The
effects of the actual crisis must be studied by specialists; and
every country and bank institutions have to adopt the new
financial order and its rules.
For this, in the present paper an important place is given to
the banking sector especially to the most important categories
of risks that may appear in every bank and their impact on each
bank’s profitability. Due to the fact that the banking sector
doesn’t have the same characteristics in every country and
region, a banking sector vision was imposed, and how could we
group these banks if not by taking into account the environment
in which they are living and mostly surviving? For this, a
banking sector rating was considered as the main characteristic
for grouping the banks taken into account.
II. BANKING SECTOR RATING &RISKS
After the beginning of the financial crisis, with reference to
the 2008-2009, a big part of the criticism went to credit ratings
assigned to banks as most failing banks had until then high
investment statuses. Ratings were subject to accusation because
of their specific use of evaluating default risk over the
economic cycle.
A credit rating constitutes in an assessment made by a
credit rating agency on qualitative and quantitative information
for the banks including exclusive information obtained by the
credit rating agencies analysts form the banks and even third
parties. The sensitive part of this process is the fact that credit
ratings are not based on mathematical formulas. The ratings are
based on the credit agencies knowledge and experience in
deciding what part of the free information to use on one hand
and which of the private information can be taken into
consideration when giving a certain rating.
In the banking sector the rating accuracy might be affected
by the opacity and complexity related to the legal structure, risk
exposures and the processes of value creation.
Rating agencies assign a letter grade to each bond which
represents an opinion as whether the organization will be able
to repay both the principal and interest obligations as they
become due.
The ratings are built on a descending scale, AAA being the
highest, AA second, A, BBB, BB, B etc. A rating of BB or
below is associated with a high risk level.
The three most important rating agencies are Moody’s,
Standard & Poor’s and Fitch Ratings.
Moody’s Bank Financial Strength Ratings (BFSRs)
represents an opinion of the bank’s intrinsic security and
assurance while excluding certain external credit risks. Bank
Financial Strength Ratings are a measure of the probability that
the bank will need assistance from third parties like its owners,
its industry group, or official institutions. The components
considered in the evaluation of the Bank Financial Strength
Ratings include bank specific factors such as financial
fundamentals, franchise value, and business and asset
diversification. [1]
