Peter
L. Bernstein in his celebrated book Against the Gods writes, 'The revolutionary
idea that defines the boundary between modern times and the past is the mastery
of risk: the notion that the future is more than a whim of the Gods and that men
and women are not passive before nature. Until human beings discovered a way across
that boundary, the future was a mirror of the past or the murky domain of oracles
and soothsayers who held monopoly over knowledge of anticipated events' (Bernstein,
1996).
Whereas
risk management characterizes many of our activities in different spheres, from
standard technological risk management embedded in almost all industrial goods
and machinery, to worrying about climate change and global warming, it is in the
world of finance that risk management is at the core of all its activities. With
the generalized opening of trade and of capital movement across the world over
the past decade and a half, risk management has become all pervasive across the
whole financial sector. In a closed economy with administered prices, fixed or
predictable exchange rates and interest rates, the micro perception of risk was
relatively benign. In those conditions, in effect, it was the sovereign that undertook
to do the risk management for the economy. As a consequence of the rigidity embedded
in these systems, economic adjustments did not take place on a day-to-day gradual
basis and risks effectively accumulated until discontinuous macroeconomic adjustments
were forced on the system. Such discontinuous adjustments involved non-marginal
adjustments in the exchange rate, interest rates, administered prices of basic
goods, or in fiscal expenditures, and the like. The impact on individuals and
market participants alike was usually relatively traumatic, and consequent economic
and financial crises were common. Moreover, such systems were likely to suffer
from misallocation of resources, bouts of price instability and consequential
low and uncertain economic growth.
The
notion that individual economic agents are ill-equipped to be exposed to exchange
rate, interest rate and price risks, and that the sovereign alone should bear
these risks is no longer regarded as tenable. It is now recognized that a system
that allows for daily market adjustment of such prices operates more smoothly
and that wider dispersion of risks among economic agents is more conducive to
the maintenance of economic and financial stability. However, the issue of how
economic risks are to be dispersed among the sovereign, financial intermediaries,
large corporations, small businesses, farmers and households and other categories
of economic agents is still a live one. It is generally acknowledged in this regard
that there has to be some correspondence between the incidence of risk and different
agents' capacity to bear it.
Lacklustre
macroeconomic performance of command economies in the 1970s and in the following
decades resulted in a shift in the thinking on risk, leading to the realization
that it is far more efficient to allow individual economic agents to face, transfer
and manage risks through a market mechanism. The collapse of the Bretton Woods
System in 1971 ushered in an era of `generalized floating' of the exchange rates
of major currencies. The gradual deregulation, relaxation/abolition of capital
controls and globalization that followed the collapse of the Soviet system provided
the backdrop as also the incentive for the risk management concepts and practices
to emerge and evolve.
The distinguishing feature of the new paradigm is that it does not mean that all risks should be eliminated by way of insurance-like products that have been known to mankind for a long time. The key is pricing of risks in markets for risk products. Development of deep and liquid markets in risk products – both cash as well derivatives - which were boosted by phenomenal progress in quantitative finance made it possible for risk management as a discipline and profession to come of age. However, this way of looking at risk management does not mean at all that there is no role for the sovereign or for regulators in financial markets.
Profound
changes have also taken place in the economic and financial landscape in India
over the last two decades or so, marked by wide-ranging reforms in both the real
and financial sectors. Adoption of a unified and market-determined exchange rate
for the rupee in early 1993, followed by current account convertibility in 1994,
enactment of a new foreign exchange law in 1999, and significant though gradual
capital account liberalization over the last decade have led to a manifold increase
in the volumes of both current and capital account transactions between India
and the rest of the world. At the same time, deregulation of interest rates, greater
use of indirect instruments for monetary policy, reduction in statutory preemption
on the resources of banks have paved the way for emergence of liquid markets for
short- and long-term interest rates in India.
The
upshot of all these developments is that while resource allocation & use have
become more efficient leading to higher growth impulses, with economic agents
now having more choices to make and competition to face, there are more risks
to contend with as well on a daily basis. In other words, increased opportunities
for economic agents are now accompanied by new types of risks to be managed as
well.
The broad trends
marking the present and the foreseeable future are clear. Economic and financial
engagement with the rest of the world will further expand in several dimensions.
Viewed from this perspective, economic agents in India should be able to walk
in step with their counterparts and competitors elsewhere. One essential requirement
in this regard is that risk management systems and procedures as well as the market
for risk management products in India should be world class.
As we introduce new risk management systems, upgrade existing ones and develop new markets for risk management products, it is very important for us to keep in mind the objective conditions that exist in India. We will need to continually keep in view the differential risk-bearing capacities among different economic agents in the country. Even among different financial intermediaries, let alone households and farmers, we have the coexistence of small and widely dispersed entities, such as primary agriculture credit societies (PACSs), rural and urban cooperative banks, public sector banks, new private sector banks, and foreign banks, with each having different degrees of sophistication related to risk management. Hence, our approach to the introduction of modern risk management instruments and systems in the country has, per force, to be cognizant of our own requirements and capacity.
Risk Management in Financial Intermediaries and Real Sector Entities
The
broad principles governing risk management are the same for entities in both the
real and financial sectors. However, risk management in banks and other financial
intermediaries acquires added importance because of their three distinguishing
characteristics: (i) they are much more leveraged; (ii) they hold public money;
and (iii) payments systems operate through banks.
In
general, banks are exposed to much more credit and interest rate risk, while the
real sector entities, particularly those which are engaged in international trade
and commodity manufacturing, processing or trade are more exposed to exchange
rate and commodity price risks. But the commodity price risk that borrowers are
exposed to gets translated into credit risk for their lenders.
Risk
management for banks and financial institutions is critically important because
they are ‘risk engines’; they take risks, they transform them and they embed them
in their products and services. There are powerful motives for banks to implement
risk-based practices; to provide a balanced view of risk and return from a management
point of view, to develop competitive advantages and to comply with regulatory
requirements.
As
is the case globally, banks in India have a very special role to play in promoting
better risk management standards and practices. Being the chief repositories of
credit risk, the quality of their loan assets depends critically on how effective
the risk management policies, processes and procedures of their borrowers are.
Among their borrowing clients themselves, there would be differentiated risk-bearing
expertise and hence banks are expected to provide professional advice to their
clients on risk management. Thus, banks have good business reasons for acquiring
specialization and professional expertise in risk management. This would, however,
be possible only if banks themselves are good managers of their own risks.
There is another related
issue, albeit a slightly deeper one. In contrast to the capital market, banks
are privy to much more wide and rich information in respect of their clients.
While the comparative advantage of banks in intermediating financial resources
hinges on their being able to enjoy economies of scale and scope in acquiring
and processing information in the first place, a relevant issue in this context
is whether this information is being put to optimal use for managing risks, both
at the level of individual banks and also at the aggregate level. Although it
is early days to assess the effectiveness of the institutional mechanism provided
by credit information bureaus for the pooling of critical borrower information
for common use within certain important safeguards, the importance of more intensive
and extensive use of information hardly needs to be overemphasized.
Further, as the economy grows and new types of activities and enterprises appear on the scene, it would be an imperative for banks to be able to assess the risks associated with such activities and enterprises. As is the case elsewhere, this will also critically depend on collection and analysis of all relevant information.
Business
Approach to Risk Management
Risk
management is an integral part of the overall business planning and management
and not something on the fringes or ‘add on’. When RBI introduced the Asset Liability
Management (ALM) framework in 1999, it was viewed by some banks initially as an
exercise for finding out maturity mismatches or re-pricing mismatches. It was
only when banks began compiling ALM statements that they realized the benefits
of pursuing pro-active asset liability management themselves. In the context of
transition to Basel II framework in India and elsewhere, where the focus is significantly
on risk management, there is a perception among some banks that this is merely
adding to their compliance costs: hence, they tend to view it as a compliance
issue. Basel II attempts to promote more advanced risk management systems, align
regulatory capital closer to economic capital and thus promote greater efficiency
in the use of capital. It is evident from the experience of the last few years,
which have witnessed gyrations in exchange rate and interest rates that banks
with better risk management policies and systems are more resilient to shocks
and volatilities, thereby creating value for their various stakeholders. Basel
II offers an opportunity to banks to become more efficient, which fact should
be accorded more importance than the regulatory requirement.
Whether
risk management is at the centrestage or on the sidelines of business operations
of banks is revealed in the pricing of various types of risks. Currently, the
interest rate charged by banks in India on various types of loans and advances
varies within an unusually wide range, say, between 6 per cent and 16 per cent,
and even higher in some cases. Visiting bankers tell me that such a range is much
wider than is observed in other markets. If this is true, is it the case that
variance in risk is much higher among Indian borrowers relative to those in other
countries? Or is it that our banks' risk appraisal techniques are faulty and that
they end up magnifying the true variance in risk? Or is it the case that the pricing
of credit is not scientifically linked to risk, leading to anomalies, such as
cross subsidization in the credit market? It could also be that the proportionate
cost of credit appraisal varies inversely with the size of loan, and banks substitute
a high credit price for the cost of credit appraisal. In this context, the introduction
of credit information bureaus, referred to earlier may be expected to make a material
difference in credit appraisal practices. Mis-pricing of credit risk is an issue,
which apart from introducing systemic vulnerability, has welfare implications
for small borrowers. Banks have access to all relevant credit information on the
borrowers/ potential borrowers and they are well positioned to use this to their
advantage while discriminating between various grades of risk. Moreover, banks
are well equipped today to re-orient their rating processes to assess the line
of activity of the counterparty, in addition to the conventional assessment of
the counterparty.
It needs to be emphasized in the context of Basel II that no amount of capital can make a financial institution absolutely secure. The key issue is proper pricing of risks. If a purely compliance attitude is taken in respect of risk management and capital adequacy, there is a danger that it may lead to ‘seat belt law’ banking. As the experience showed in many countries with mandatory use of seat belts, it became apparent soon that drivers were prepared to take more risks, believing themselves to be safer. Proper management of risks is the key. Risk management should be integrated with the activity of risk taking – one need to structure one’s position according to the risks understood by him or her. Risks that are not understood well should be avoided.
Stress
Testing
The
corollary to increased risk related to the expectation of greater fluctuation
in prices, exchange rates, and interest rates, is the need for developing regular
systems for stress testing. In fact, the antidote to excessive complacency resulting
from greater risk-related capital adequacy is the use and consciousness of regular
stress testing.
Globally,
stress testing is becoming an integral part of banks’ risk management systems
and is used to evaluate their potential vulnerability to certain unlikely but
plausible events or movements in financial variables. In the above background,
the need for banks in India to adopt ‘stress tests’ as a risk management tool
has been emphasised in the Annual Policy Statement announced by the Governor in
April 2006. The draft guidelines that were issued in this regard are now being
given a final shape on the basis of the feedback that has been received from market
participants. An efficient stress test framework is necessary to incorporate a
forward looking element in banks’ business strategies. Banks would do well to
approach stress testing not merely as a regulatory requirement but as an integral
part of their risk management processes and Basel II implementation. The stress
test results need to be suitably integrated into the risk management processes,
business strategies and capital planning.
Just as stress testing is important at the enterprise level, we need to upgrade our stress testing procedures at the systemic level as well. In the aftermath of the Asian financial crisis, and in the context of the increased discussion on global financial architecture, the World Bank and the IMF introduced a new procedure for 'Financial System Assessment Programmes' (FSAPs). India was one of the first countries to volunteer for this programme in 1999. We are now engaged in an update of that exercise, which we are doing ourselves so that such assessment programmes get internalized within the system. Such a programme also helps in coordinating approaches and thinking between the government and all the financial sector regulators.
Operational
Risk Management
Operational
risk is assumed during the normal course of business along with other major risks
viz. credit risk or market risk, and is not normally assumed independently on
a risk-return basis. Operational risk management is particularly relevant to banks,
because although they are able to either transfer or hedge a portion of their
other major risks viz. credit and market risk exposures, operational risk cannot
be hedged or transferred. Further, banks are increasingly undertaking transaction
processing, asset management services, cash management services, and sale of sophisticated
financial products which are generating a fair amount of revenue. Banks have also
begun using models for managing their credit and market risks and this exposes
them to model risks. Banks increasingly use computers and IT for a larger segment
of their operations, including certain critical operations, and this exposes them
to a significant degree of operational risk. Further, banks are exposed to reputational
risk to a considerable extent which has not yet been formally taken on board and
addressed as a risk element in many banks. Since operational risk has changed
its complexion due to the above factors, banks need to take a comprehensive view
in this regard to have a wholesome picture of their exposure to operational risk.
Traditionally,
some aspects of operational risks have been sought be minimized through internal
inspection and audit. However, there is a need to recast and modernize this function
so as to transform it into a mechanism designed to operate on the whole suite
of operational risk events.
The issue of operational risk has assumed higher importance worldwide in recent years with the increased prevalence of outsourcing, particularly overseas. With India being a major recipient of such outsourcing, this issue assumes even greater importance for us. Banks and other financial intermediaries have to understand that operational risk management in their outsourced operations is their own responsibility. This issue has also given rise to a good deal of discussion among financial regulators: to what extent should they be examining risk management procedures in outsourced entities or how can they assess the risk management procedures in the regulated entities as they relate to their service providers?
Risk
Management and the use of Financial Derivatives
The implication of the huge expansion in the use of financial derivatives that has taken place over the past five years is attracting increasing discussion among financial sector regulators. How do we assess their impact on financial stability and systemic risk? The most succinct and lucid discussion of this general issue that I have come across is in a brief speech given just 2 weeks back by my US counterpart, Donald Kohn of the Federal Reserve Bank. As he puts it very eloquently, '….. (t)he securitization of mortgages and other assets has been transforming regulated depository institutions from holders of interest rate risk and credit risk to originators and distributors of such risk' (Kohn, 2007)
What is the situation in India in respect of financial derivatives?
Use
of Financial Derivatives in India
A
liquid market for forward foreign exchange contracts has existed in India for
several decades now. This product is still the main instrument for hedging foreign
exchange risk in India, although foreign currency options are also getting increasingly
popular. Over the last 10 years or so, several other types of derivatives have
begun trading in India. As you are aware, efforts are on for introduction of credit
derivatives in India. Feasibility probes for foreign exchange futures have begun.
Efforts are also on for an appropriate design for interest rate futures. In the
recent years, the regulatory ecosystem for financial derivatives has been sought
to be made more effective and straightforward. Insertion of a new Chapter IIID
to the RBI Act, 1934 by way of an amendment in 2006 has been a milestone in this
regard, since this has provided legal clarity as regards OTC derivatives and has
also defined regulatory domain and scope. Accounting treatment of financial derivatives
in banks is also being streamlined so as to be broadly in tune with international
standards.
What are
the issues that we need to be concerned about as the use of financial derivatives
increases in India? We need to understand that, as reflected Donald Kohn's remark
that I have just quoted, we will witness a significant change in the function
of financial sector intermediaries over time, as the use of financial derivatives
gathers force. We will need to prepare ourselves for these changes from the regulatory
point of view as will the financial intermediaries themselves in their internal
risk operations. As has been the case in some developed markets, with growth in
securitization and expansion of credit derivatives, if banks which are now the
storehouse of credit risks are to significantly abandon this space, what implication
could this have for financial stability.
With
more distribution of risk we will need to address the issue of where will the
risks rest. We will also need to assess the capability of market participants
who will ultimately bear the risks. Will they be such that regulators do not need
to regulate them? Will financial regulators even need to know where the risks
are distributed? One view is that as long as the participants in this market are
large institutional investors, or high net worth individuals, they will need no
protection. Let the risks be distributed among those who wish to take such risk,
and let it be distributed according to their capacity as determined by the market
itself. Hence, there is no need for any safety net like the one that is implicitly
embedded in the lender of last resort role of central banks. What will be important
in such markets is the availability of adequate market liquidity at all times
for them to operate efficiently, enabling market participants to take and liquidate
positions as necessary. The job for regulators would then be to ensure that there
is adequate depth in the markets, that clearing and settlement systems are efficient
and safe, that there are no dominant market players who can move markets, and
that the players are themselves large and sophisticated. In times of market stress,
the only issue would be the availability of adequate liquidity.
Given
that the extraordinary growth of credit and other financial derivatives is still
a relatively new phenomenon, and that this has happened in the context of accommodative
monetary policies in G3 countries in recent years, it is too early to assess how
such markets will work in times of stress and what the overall regulatory approach
should then be.
One
positive side of this assessment is that, unlike the 1980s and 1990s, when financial
crises were frequent in developing and developed countries alike, the past decade
has been remarkably free of such crises, worldwide. High oil prices, large business
failures, large stock market fluctuations that have been witnessed in this period
have not resulted in financial crises, or disruptive effects on financial intermediaries.
This is attributed to the wider dispersion of risk by some, whereas others point
to the overall benign macroeconomic and healthy global growth conditions that
have prevailed over this period.
What
is my take on these international developments and their implications for India?
I don't have a clear answer. We need to embrace these financial developments in
such a way that we continue to ensure financial stability, and that we enable
domestic market participants, both financial and non-financial, to increasingly
deal with the kind of risks that are emerging with greater market liberalization
both at home and abroad.
As
a monetary authority and financial sector regulator, we will need to enhance our
own risk management capacity, both for our internal purposes, but also as evaluators
of the risk management capacity of regulated entities. We will continuously endeavour
to enhance the risk management skills and capabilities of market participants
and improve the micro-infrastructure of markets so that financial stability is
maintained. Meanwhile, we will need to keep in mind the very varied nature of
our economy that I had alluded to earlier.
The key to our approach to the development of financial derivatives in India has to be a proactive stance for the adoption of robust risk management systems within the relevant financial intermediaries and, from our point of view, particularly in banks. We have to ensure that the introduction of new risk instruments actually increases the risk management capabilities of the system as a whole, and not the other way round because of inadequate preparation.
Reflections
on Risk Management at RBI
The
Reserve Bank of India, like all other central banks is also a financial
institution that is exposed to a variety of risks. Over the last several years,
there has been a structural transformation of the risk exposure of the RBI in
that as against pre-dominantly rupee-denominated assets figuring on its balance
sheet, it now has an overwhelming proportion of assets denominated in major foreign
currencies. This transformation means more volatility in its asset valuation in
rupee terms as also in the current earnings in rupee terms. It needs to be emphasized
that while a bank or a corporate in any country can choose to eliminate foreign
currency risk, a central bank like the RBI, which does not have any liability
in foreign exchange, cannot hedge exchange rate risk beyond a very modest extent.
The approach followed by the RBI in this regard for a very long time has been
to have a diversified portfolio of reserves, both in terms of currencies and instruments
and a strong level of capitalization. The RBI has also been very transparent in
disclosing its risk management policies in annual reports and also in half-yearly
reports of reserves management since January 2005.
In addition to the issues related to market risk management of our assets and, hence, the integrity of our balance sheet, which is so essential for the financial system as a whole, we have to deal increasingly with the issues of operational risk that I had outlined earlier. As the institution responsible for the payment and settlement system we are giving increased attention to all our own IT systems, back up, alternative sites, and the like.
Limits
of Risk Management
Adoption
of risk management policies and practices by economic entities in the sense that
they assume risk by choice and not by chance is value enhancing. However, hedging
through market instruments results in a redistribution of risks. Ideally, if this
redistribution is done on the basis of a scientific appraisal of the optimal level
and combination of risks for each entity it may result in an overall reduction
of risks at the macro level. But the economy as a whole would still be exposed
to risks. Also, for proper functioning of hedging products it is essential that
expectations about the risk variable should be heterogeneous. If price movements
are unidirectional for a long time, protection sellers demand large premium from
protection buyers.
Apart
from the above, there are more subtle issues concerning risk management. It is
well-known that markets flagrantly violate some of the postulates and assumptions
of traditional mathematical finance. The volatility of financial prices and the
tendency of this volatility to occur sometimes in episodes generally unrelated
to any clearly exogenous news about fundamentals has been a subject of research
for a long time in behavioural finance.
The
behavioral dimensions of risk management and hedging have attracted much attention
in the recent years among academics and researchers. Among other things, hedging
decisions of any entity are influenced by two important factors: (a) stance of
the competitors in this regard; and (b) anomalies of human behaviour. The latter-mentioned
aspect is significant: most often entities do not always have the intellectual
or emotional impulse to take on risks and deal with them before they impinge on
performance and it is too late. Many do not feel the same way when they buy a
luxury car and when they buy insurance for the same car. When we are educated
to risk management possibilities, we become aware of the rich potential that finance
has for improving human welfare, but we do not find it emotionally easy always
to take advantage of this potential. Experienced traders know it too well how
difficult it is at times to quit a loss-making position. The field of risk management
needs to design its methods to minimize the human weakness in risk management.
Finally, have adoption of risk management and use of risk mitigation products made the financial markets a safer place than before? It is a tough call to take. In a recent interview, Professor Robert Merton, who along with Myron Scholes and Fischer Black invented the famous option pricing formula in the early 1970s, reportedly said, ‘The real story is not what happened to LTCM in 1998 but what happened to Amaranth later – or rather what did not happen….institutions have adjusted and we have learnt to deal with some of these crises which are not crises any more’ (Tett, 2007).
