The world of finance has always had an intuitive
understanding of risk. The risks that emerge from the increased variety and
complexities of banking business, as well as from the various new drivers of
growth has pushed the contours of risk management in banks much beyond what
would probably have existed in the more traditional forms of banking activity
of accepting deposits and lending in relatively stable environments. Internationally,
the last two decades or so have witnessed significant changes in the profile
of the banking sector, as well the nature of risk management in banks. What
perhaps has changed the nature of risk management, particularly are, inter-alia,
advances in technology that have aided quantitative approaches to risk management,
like models etc., and the increasing volumes of transactions in derivatives
and other structured products that are so complex that they are often labeled
"exotic". India too has responded to this change, tempered with a
gradualist, non disruptive approach, that has stood us in good stead over the
years.
In my brief remarks today, I intend to first,
highlight few of the broader and more general issues currently engaging the
financial risk management fraternity and then, move to the Indian context in
this regard.
I. Some general perspectives on risk management
Quantification of risk and model risk: As
mentioned earlier, significant developments in the area of quantification of
risk, has shifted focus to statistical aspects of risk management, especially
to risk modeling and other computational techniques of risk measurement. During
the last decade there has been a proliferation of academic research on the use
of VaR for market risk assessment. Such models have to be used with some care
and serious examination of the data used, especially the use of historical data
for forecasting future scenarios, the assumptions behind the models, estimation
errors etc. Further, if intraday positions are not captured it would expose
banks to such risks.
Similarly in respect of Credit Risk, there is
no single ‘‘best practice’’ model for credit risk capital assessment, although
the Basel 2 ‘‘Internal Rating Based’’ methodology provides a portfolio model.
Bank managements will have to focus on the determinants of credit risk factors,
the dependency between risk factors, the integration of credit risk to market
risk, data integrity issues like consistency of data over long periods, accuracy
and so on.
Institutions are already mapping events to operational
loss categories and building warehouses of operational risk data for implementation
of Advanced Measurement Approaches. Many data availability and reliability issues
still need resolving. An internal loss experience for the important (low frequency,
high severity) operational risk types is rare and any relevant data are likely
to be in the form of risk self-assessments and/or external loss experiences.
Extreme events and stress testing: One
of the key roles of the risk management process is to manage extreme events,
such as those associated with the tails of statistical distributions and could
have probability of occurrence as low as one percent. These are low probability
but high loss instances associated with extreme operational events such as rogue
trading or accounting fraud. The importance of stress testing to assess the
impact of not only these events but also the impact of various scenarios is
engaging the attention of risk management personnel, academicians and bankers
alike
Risk based capital and back-testing: An
important reason as to why the quantitative techniques have received so much
attention, is not because of the intellectual satisfaction it can give to the
academician but a rather mundane reason that it can be used to convince the
regulator that given the risks as measured by these techniques the amount of
capital required could be far less than that may be stipulated under broad brush,
standardized techniques. An immediate linkage between the risk models, the quantum
of risk that is measured by use of these models and the capital that is required
to support these risks immediately emerge. Estimates of capital being sufficient
to meet the risk can be only as good as the models are and the credibility of
the models would ultimately depend upon their actual performance. Back testing
the models to gauge and reduce the variance between the deviations of the actual
numbers from those projected are largely relied upon to give a degree of comfort
to both management of banks and supervisors alike.
II. Indian Perspective
Internationally, there has been a continuous
coordinated effort under the aegis of institutions like the BIS to evolve best
practices in risk management in banks and these have gradually come to be accepted
as some sort of international standards for banks across the world to benchmark
themselves to. At the regulatory and supervisory level also, there has been
an effort to achieve convergence to the best practices set out by the BCBS after
duly allowing for national characteristics and feasibility. Banks have responded
to this initiative with varying levels of effectiveness.
It was in October 1999, that the Reserve Bank
issued guidelines on Risk Management in banks setting out its expectations from
banks; the guidelines adopted an integrated approach to risk management. Even
earlier, in February 1999, banks were advised to set up an asset liability management
framework to manage liquidity and interest rate risk. In this context, I would
like to make following observations:
- The need to accelerate the speed at which banks have been
moving towards establishment of risk management systems
- The need to achieve convergence with regulatory and supervisory
expectations/requirements while deciding on the sophistication of methods
to be adopted.
- Developing appropriate risk management architecture, MIS
and skill enhancement
- The need to integrate risk management process with capital
planning strategies
The current business environment, with its pointed
emphasis on corporate governance, is making it critical for banks to explain
their risk profiles publicly with greater clarity and detail than ever before.
Risk is still a complex and technical subject, so achieving transparency will
not be easy. Internal constituents, analysts, ratings agencies, investors, and
regulators all have varying levels of understanding of advanced risk measurement
techniques. All will require continuing education before the market as a whole
reaches a common understanding of risk. In particulars, direct stakeholders
in any transaction need to be aware of the risks involved. For the third pillar
of Basle II (Market Discipline) to be efficacious, it is important that the
stakeholders are aware of the risks involved in the banks’ transactions and
the systems in place to manage the risks. In this context, the importance of
an appropriateness policy for banks offering various products to the corporate
clients can't be over-emphasised.
The risk management systems developed by banks
would include a lot of attention of top management to the suitability of IT
structure including issues of connectivity, designing an MIS format that is
risk focused, setting up an organization to manage risk that ensures segregation
of risk assessment from operations, frequent review of risk management systems
to ensure there is no slippage and last but not the least, to develop appropriate
skills within the organization. In this context, it must be kept in view that
risk management is not the sole concern of the risk management department but
rather a culture that pervades the whole organization with specific support
from the top management.
III. Recent initiatives in risk management
In India, over the years various steps have
been taken to strengthen the Risk Management Architecture, both at the bank
specific level as well as a broader systemic level.
ALM Guidelines: Most banks have put in
place an ALM framework. However there is lot to be done to internalize this
framework as a part of the overall risk perceptions of the bank and the capital
planning strategy of the bank. Issues in data infirmity still remain to some
extent. In many cases, the ALCO’s role remains confined to deciding on interest
rates of the bank. This is partly due to lack of decision support system available
to the ALCO. Availability of impact and scenario analysis of changes in yield
structures would be a significant enabling factor.
The Reserve Bank has recently issued draft guidelines
to banks with the objective of graduating from the current maturity ladder approach
prevalent in most banks to a duration gap approach. The later approach makes
it possible for banks to calculate the modified duration of assets and liabilities,
the duration gap and duration of equity. The concept of duration of equity gives
banks, subject to certain limitations, a single number indicating the impact
of a one per cent change of interest rate on its capital, captures the interest
rate risk and thereby helps move a step forward towards assessment of risk based
capital/economic capital.
Credit risk: Another important issue
is that bank resources and supervisory resources have concentrated on credit
risk modeling of commercial and industrial portfolios, with relatively fewer
resources devoted to risk quantification in the retail credit area. The possible
reasons could be (i) from a systemic perspective, it makes economic sense to
devote more resources to evaluating the risk factors of larger loans (ii) there
is a long history of ratings agency evaluations for publicly traded firms which
, along with the extensive data available for publicly traded firms, provided
an extremely useful benchmark for the development of quantification methods
for commercial portfolios.
However, despite this commercial side emphasis,
retail credit is a substantial part of the risk borne by the banking industry,
and can not be ignored. Recognizing this, over the last decade or so, the industry
and academia have devoted significant resources to developing more sophisticated
credit-scoring models for measuring this risk. Like their counterparts on the
commercial side, these models also rely heavily on quantitative analysis.
Derivatives: There has been a spurt of
derivatives exposures in the off balance sheet exposures. The composition of
derivatives portfolio of the banking system has also undergone a significant
transformation. Forward foreign exchange contracts which accounted for around
80% of total derivatives in March 2002 declined steadily and stood at almost
43% in March 2006 while the share of interest rate contracts went up from 19%
to 54% during the same period. Foreign currency options have recorded noticeable
increase during the last year. The share of single currency interest rate swaps
in total derivatives of the banking system has risen sharply from 15% in March
2002 to 53% in March 2006.
The risks arising on account of OBS activities
of banks are controlled through a combination of both banks’ internal risk management
and control policies and risk mitigation mechanism imposed by the regulators.
The board approved internal control policies covering various aspects of management
of risks arising both on and off balance sheet exposures constitute the first
line of defence to the bank. Holding of minimum defined regulatory capital for
all OBS exposures, collection of periodic supervisory data and incorporating
transparency and disclosure requirements in bank balance sheet are some of the
major regulatory initiatives undertaken to control and monitor OBS exposures
of the banking system.
The rapid proliferation of derivatives exposures
inevitably poses a challenge on account of the downside risks associated with
them, if not managed properly. There are issues relating to use of structured
products, valuation, counterparty related issues, risk management and reporting
issues and last but not the least, training and skill development. While derivatives
facilitate risk hedging and risk transfer to institutions more willing to bear
the risks, the tendency of participants to use derivatives to assume excessive
leverage, and lack of prudential accounting guidelines are matters of concern.
One of the features of in the Indian derivative
market relates to concentration risk in respect of both the market makers (banks)
and the corporates. The combined share of top 15 banks has steadily grown from
around 74% in March 2002 to 82% of total OBS exposures of the banking system
in March 2006, of which 62% is accounted for by foreign banks. Concentration
of knowledge is another risk which results in the concentration of derivative
activity among few players.
RBI has been stressing on the need to carry
out due diligence regarding customer appropriateness and suitability of products
before offering derivative products to their customers. There is need to use
risk mitigation techniques such as collaterals and netting to reduce systemic
risks and evolve appropriate accounting guidelines.
RBI has also issued two separate draft guidelines,
one for valuation/accounting of investment portfolio in general and the second
relating to derivatives. The proposed guidelines attempt to put in place fair
value accounting norms for derivatives broadly in line with IAS 39, the international
accounting standard for valuation and accounting for financial instruments.
For investments, the proposed framework envisages a symmetrical treatment for
unrealized gains and losses, with gains for HFT being reflected in the Profit
and loss account. For AFS, however, a gain or loss on subsequent measurement
shall be reflected in ‘Unrealised gain/ loss on AFS portfolio’. Similarly for
derivatives, all valuation gains and losses are proposed to be routed either
through the P&L (for less than 90 days) and or through a new account titled
' Unrealised gains/losses on derivatives' (90 days and more), somewhat similar
to AFS portfolio. The idea is to bring all derivative transactions 'on-balance
sheet' as against 'off-balance sheet' as is being done currently.
Further, in order to address all issues related
to derivatives in a comprehensive manner, we are now in the process of harmonizing
the regulatory prescriptions based on generic principles rather than approving
specific products.
Stress Testing: The Governor in his Monetary
Policy for 2006-07 had stressed the need for banks to have robust stress testing
process for assessment of capital adequacy given various possible events like
economic downturns, industrial downturns, market risk events and sudden shifts
in liquidity conditions. Similarly exposures to sensitive sectors and high risk
category of assets would have to be subjected to more frequent stress tests
based. Stress tests would enable banks to assess the risk more accurately and,
thereby, facilitate planning for appropriate capital requirements.
Subsequently RBI has issued draft guidelines
on stress testing. These guidelines cover all major risk areas viz. market risks,
credit risks, operational risks and liquidity funding risk. Banks are required
to identify an appropriate range of realistic adverse circumstances and events
in which the identified risk crystallises and estimate the financial resources
needed by it under each of the circumstances to : a) meet the risk as it arises
and for mitigating the impact of manifestation of that risk; b) meet the liabilities
as they fall due; and c) meet the minimum CRAR requirements. It may be pertinent
to note that the banks have been advised to apply stress tests at varying frequencies
dictated by their respective business requirements, relevance and cost.
Financial Conglomerates: There is increasingly
a need to extend the framework of risk management to the group wide level, particularly
among financial conglomerates. The rapid expansion of financial services, both
in terms of volumes and variety have, as it is, posed a challenge for financial
stability. This is made all the more difficult by the organisational dimension
which perhaps provides scope for regulatory arbitrage. While this could appear
beneficial to the organisation in the short run, it only hightens systemic risk
that in turn exposes the institution to externalities which have a cost. There
has been entry of some banks into other financial segments like merchant banking,
insurance and several new players have emerged who have a diversified presence
across major segments of financial sector. Some of the non-banking institutions
in the financial sector can acquire proportions large enough to have a systemic
impact. It has, therefore, become necessary not only for the supervisor to have
a "conglomerate" approach to regulation and supervision but also for
banks themselves to put in place risk management systems at global levels i.e
for the whole organizational as a whole, rather than only the bank level. The
risks associated with conglomeration may include:
1. The moral hazard associated with the ‘Too-Big-To-Fail’
position of many financial conglomerates;
2. Contagion or reputation effects on account of the 'holding out' phenomenon;
3. Concerns about regulatory arbitrage, non-arm’s length dealings, etc. arising
out of Intra-group Transactions and Exposures (ITEs) both financial and non-financial
It is in this context that the issue of integrated
risk management, at the enterprise wide as well as group wide level, acquires
significance. RBI has put in place a framework for oversight of financial conglomerates,
along with SEBI and IRDA. Half-yearly discussions have also been initiated with
the Chief Executive Officers of the designated entities of the conglomerates
to address outstanding issues/ supervisory concerns.
IV. To conclude, at the systemic
level, efforts have been made to create an enabling environment for all market
participants in terms of regulation, infrastructure and instruments. In this
context, let me mention about two recent legislative developments that may have
far reaching impact on the financial markets in India. One is the promulgation
of the RBI (Amendment) Act, 2006. A major issue of concern in the OTC derivatives
market in India was the issue of legality. While the Securities Contract Regulation
Act, 1956 gave specific legal recognition to derivative instruments traded in
the exchanges, there was no explicit legal recognition of OTC derivatives in
India. As legal clarity is a basic requirement for the healthy development of
any market, legality of OTC derivatives was provided by an appropriate amendment
to the RBI Act, with retrospective effect. RBI has also been now empowered to
regulate the interest rate and forex OTC derivatives market. The second legislative
development pertains to the enactment of Government Securities Bill. The substantive
changes brought about in the Government Securities Act are that it provides
for hypothecation, pledge and lien of government securities, maintenance of
records in electronic form and most importantly, enables STRIPing of Government
securities.
Further, during the last few months, few liberalization
measures have been introduced in securities market, that would surely have a
bearing on the risk management practices in the market, the most important being
introduction of 'when issued' trading and short selling in the G-Sec markets
in a limited way. Currently the when issued trading is limited to reissuances
only. We are examining extending this to new issuances also, as requested by
market participants.
What has developed incrementally over the years
is now being consolidated and once the regulations, infrastructure and appropriate
accounting standards stabilize, several other initiatives like credit derivatives
could be considered.
