Purpose This joint agency policy statement provides guidance
to banks on prudent interest-rate risk management principles. The
three federal banking agencies—the Board of Governors of the Federal
Reserve System, the Federal Deposit Insurance Corporation, and the
Office of the Comptroller of the Currency (“agencies”)—believe that
effective interest-rate risk management is an essential component
of safe and sound banking practices. The agencies are issuing this
statement to provide guidance to banks on this subject and to assist
bankers and examiners in evaluating the adequacy of a bank’s management
of interest-rate risk.
1
This statement applies to all federally
insured commercial and FDIC-supervised savings banks (“banks”). Because
market conditions, bank structures, and bank activities vary, each
bank needs to develop its own interest rate risk management program
tailored to its needs and circumstances. Nonetheless, there are certain
elements that are fundamental to sound interest-rate risk management,
including appropriate board and senior management oversight and a
comprehensive risk-management process that effectively identifies,
measures, monitors, and controls risk. This statement describes prudent
principles and practices for each of these elements.
The adequacy and effectiveness of a bank’s
interest-rate risk management process and the level of its interest-rate
exposure are critical factors in the agencies’ evaluation of the bank’s
capital adequacy. A bank with material weaknesses in its risk-management
process or high levels of exposure relative to its capital will be directed
by the agencies to take corrective action. Such actions will include
recommendations or directives to raise additional capital, strengthen
management expertise, improve management information and measurement
systems, reduce levels of exposure, or some combination thereof, depending
upon the facts and circumstances of the individual institution.
When evaluating the applicability of specific guidelines
provided in this statement and the level of capital needed for interest-rate
risk, bank management and examiners should consider factors such as
the size of the bank, the nature and complexity of its activities,
and the adequacy of its capital and earnings in relation to the bank’s
overall risk profile.
Background
Interest-rate risk is the exposure of a bank’s financial
condition to adverse movements in interest rates. It results from
differences in the maturity or timing of coupon adjustments of bank
assets, liabilities, and off-balance-sheet instruments (repricing
or maturity-mismatch risk); from changes in the slope of the yield
curve (yield-curve risk); from imperfect correlations in the adjustment
of rates earned and paid on different instruments with otherwise similar
repricing characteristics (basis risk —e.g., three-month Treasury
bill versus three-month LIBOR); and from interest rate-related options
embedded in bank products (option risk).
Changes in interest rates affect a bank’s earnings by
changing its net interest income and the level of other interest-sensitive
income and operating expenses. Changes in interest rates also affect
the underlying economic value
2 of the bank’s assets, liabilities and off-balance-sheet
instruments because the present value of future cash flows and in
some cases, the cash flows themselves, change when interest rates
change. The combined effects of the changes in these present values
reflect the change in the bank’s underlying economic value.
As financial intermediaries, banks
accept and manage interest-rate risk as an inherent part of their
business. Although banks have always had to manage interest-rate risk,
changes in the competitive environment in which banks operate and
in the products and services they offer have increased the importance
of prudently managing this risk. This guidance is intended to highlight
the key elements of prudent interest-rate risk management. The agencies
expect that in implementing this guidance, bank boards of directors
and senior managements will provide effective oversight and ensure
that risks are adequately identified, measured, monitored, and controlled.
Board and Senior Management Oversight Effective board and senior management oversight of
a bank’s interest-rate risk activities is the cornerstone of a sound
risk-management process. The board and senior management are responsible
for understanding the nature and level of interest-rate risk being
taken by the bank and how that risk fits within the overall business
strategies of the bank. They are also responsible for ensuring that
the formality and sophistication of the risk-management process is
appropriate for the overall level of risk. Effective risk-management
requires an informed board, capable management, and appropriate staffing.
For its part, a bank’s board of directors has two broad
responsibilities:
- to establish and guide the bank’s tolerance for interest-rate
risk, including approving relevant risk limits and other key policies,
identifying lines of authority and responsibility for managing risk,
and ensuring adequate resources are devoted to interest-rate risk
management
- to monitor the bank’s overall interest-rate risk profile
and ensure that the level of interest-rate risk is maintained at prudent
levels
Senior management is responsible for ensuring that interest-rate
risk is managed on both a long-range and day-to-day basis. In managing
the bank’s activities, senior management should —
- develop and implement policies and procedures that
translate the board’s goals, objectives, and risk limits into operating
standards that are well understood by bank personnel and that are
consistent with the board’s intent;
- ensure adherence to the lines of authority and responsibility
that the board has approved for measuring, managing, and reporting
interest-rate risk exposures;
- oversee the implementation and maintenance of management
information and other systems that identify, measure, monitor, and
control the bank’s interest-rate risk; and
- establish internal controls over the interest-rate
risk management process.
Risk-Management Process
Effective control of interest-rate risk requires a comprehensive
risk-management process that includes the following elements:
- policies and procedures designed to control the nature
and amount of interest-rate risk the bank takes, including those that
specify risk limits and define lines of responsibilities and authority
for managing risk
- a system for identifying and measuring interest-rate
risk
- a system for monitoring and reporting risk exposures
- a system of internal controls, review, and audit to
ensure the integrity of the overall risk-management process
The formality and sophistication of these elements may
vary significantly among institutions, depending upon the level of
the bank’s risk and the complexity of its holdings and activities.
Banks with noncomplex activities and relatively short-term balance-sheet
structures presenting relatively low risk levels and whose senior
managers are actively involved in the details of day-to-day operations
may be able to rely on a relatively basic and less formal interest-rate
risk management process, provided their procedures for managing and
controlling risks are communicated clearly and are well understood
by all relevant parties.
More complex organizations and those with higher interest-rate
risk exposures or holdings of complex instruments with significant
interest rate - related option characteristics may require more elaborate
and formal interest-rate risk management processes. Risk-management
processes for these banks should address the institution’s broader
and typically more complex range of financial activities and provide
senior managers with the information they need to monitor and direct
day-to-day activities. Moreover, the more complex interest-rate risk
management processes employed at these institutions require adequate
internal controls that include internal and/or external audits or
other appropriate oversight mechanisms to ensure the integrity of
the information used by the board and senior management in overseeing
compliance with policies and limits. Those individuals involved in
the risk-management process (or risk-management units) in these banks
must be sufficiently independent of the business lines to ensure adequate
separation of duties and to avoid conflicts of interest.
Risk Controls and Limits
The board and senior management
should ensure that the structure of the bank’s business and the level
of interest-rate risk it assumes are effectively managed and that
appropriate policies and practices are established to control and
limit risks. This includes delineating clear lines of responsibility
and authority for the following areas:
- identifying the potential interest-rate risk arising
from existing or new products or activities
- establishing and maintaining an interest-rate risk
measurement system
- formulating and executing strategies to manage interest-rate
risk exposures
- authorizing policy exceptions
In some institutions the board
and senior management may rely on a committee of senior managers to
manage this process. An institution should also have policies for
identifying the types of instruments and activities that the bank
may use to manage its interest-rate risk exposure. Such policies should
clearly identify permissible instruments, either specifically or by
their characteristics, and should also describe the purposes or objectives
for which they may be used. As appropriate to the size and complexity
of the bank, the policies should also help delineate procedures for
acquiring specific instruments, managing portfolios, and controlling
the bank’s aggregate interest-rate risk exposure.
Policies that establish appropriate risk limits
that reflect the board’s risk tolerance are an important part of an
institution’s risk-management process and control structure. At a
minimum, these limits should be board-approved and ensure that the
institution’s interest-rate exposure will not lead to an unsafe and
unsound condition. Senior management should maintain a bank’s exposure
within the board-approved limits. Limit controls should ensure that
positions that exceed certain predetermined levels receive prompt
management attention. An appropriate limit system should permit management
to control interest-rate risk exposures, initiate discussion about
opportunities and risk, and monitor actual risk taking against predetermined
risk tolerances.
A bank’s limits should be consistent with the bank’s overall
approach to measuring interest-rate risk and should be based on capital
levels, earnings, performance, and the risk tolerance of the institution.
The limits should be appropriate to the size, complexity, and capital
adequacy of the institution and address the potential impact of changes
in market interest rates on both reported earnings and the bank’s
economic value of equity (EVE). From an earnings perspective, a bank
should explore limits on net income as well as net interest income
in order to fully assess the contribution of non-interest income to
the interest-rate risk exposure of the bank. Such limits usually specify
acceptable levels of earnings volatility under specified interest-rate
scenarios. A bank’s EVE limits should reflect the size and complexity
of its underlying positions. For banks with few holdings of complex
instruments and low risk profiles, simple limits on permissible holdings
or allowable repricing mismatches in intermediate- and long-term instruments
may be adequate. At more complex institutions, more extensive limit
structures may be necessary. Banks that have significant intermediate-
and long-term mismatches or complex options positions should have
limits in place that quantify and constrain the potential changes
in economic value or capital of the bank that could arise from those
positions.
Identification
and Measurement Accurate and timely
identification and measurement of interest rate risk are necessary
for proper risk management and control. The type of measurement system
that a bank requires to operate prudently depends upon the nature
and mix of its business lines and the interest-rate risk characteristics
of its activities. The bank’s measurement system(s) should enable
management to recognize and identify risks arising from the bank’s
existing activities and from new business initiatives. It should also
facilitate accurate and timely measurement of its current and potential
interest-rate risk exposure.
The agencies believe that a well-managed bank will consider
both earnings and economic perspectives when assessing the full scope
of its interest-rate risk exposure. The impact on earnings is important
because reduced earnings or outright losses can adversely affect a
bank’s liquidity and capital adequacy. Evaluating the possibility
of an adverse change in a bank’s economic value of equity is also
useful, since it can signal future earnings and capital problems.
Changes in economic value can also affect the liquidity of bank assets,
because the cost of selling depreciated assets to meet liquidity needs
may be prohibitive.
Since the value of instruments with intermediate and long
maturities or embedded options is especially sensitive to interest-rate
changes, banks with significant holdings of these instruments should
be able to assess the potential longer-term impact of changes in interest rates
on the value of these positions and the future performance of the
bank.
Measurement systems for evaluating the effect of rates
on earnings may focus on either net interest income or net income.
Institutions with significant non-interest income that is sensitive
to changing rates should focus special attention on net income. Measurement
systems used to assess the effect of changes in interest rates on
reported earnings range from simple maturity-gap reports to more sophisticated
income-simulation models. Measurement approaches for evaluating the
potential effect on economic value of an institution may, depending
on the size and complexity of the institution, range from basic position
reports on holdings of intermediate, long-term and/or complex instruments
to simple mismatch weighting techniques to formal static or dynamic
cash-flow-valuation models.
Regardless of the type and level of complexity of the
measurement system used, bank management should ensure the adequacy
and completeness of the system. Because the quality and reliability
of the measurement system is largely dependent upon the quality of
the data and various assumptions used in the model, management should
give particular attention to these items.
The measurement system should include all material interest-rate
positions of the bank and consider all relevant repricing and maturity
data. Such information will generally include (i) current balance
and contractual rate of interest associated with the instruments and
portfolios; (ii) principal payments,interest-reset dates, and maturities;
and (iii) the rate index used for repricing and contractual interest-rate
ceilings or floors for adjustable-rate items. The system should also
have well-documented assumptions and techniques.
Bank management should ensure that risk is
measured over a probable range of potential interest-rate changes,
including meaningful stress situations. In developing appropriate
rate scenarios, bank management should consider a variety of factors
such as the shape and level of the current term structure of interest
rates and historical rate movements. The scenarios used should incorporate
a sufficiently wide change in market interest rates (e.g., +/− 200
basis points over a one year horizon) and include immediate or gradual
changes in market interest rates as well as changes in the shape of
the yield curve in order to capture the material effects of any explicit
or embedded options.
Assumptions about customer behavior and new business activity
should be reasonable and consistent with each rate scenario that is
evaluated. In particular, as part of its measurement process, bank
management should consider how the maturity, repricing, and cash flows
of instruments with embedded options may change under various scenarios.
Such instruments would include loans that can be prepaid without penalty
prior to maturity or have limits on the coupon adjustments, and deposits
with unspecified maturities or rights of early withdrawal.
Monitoring and Reporting Exposures
Institutions should also establish an adequate system
for monitoring and reporting risk exposures. A bank’s senior management
and its board or a board committee should receive reports on the bank’s
interest-rate risk profile at least quarterly. More frequent reporting
may be appropriate depending on the bank’s level of risk and the potential
that the level of risk could change significantly. These reports should
allow senior management and the board or committee to—
- evaluate the level and trends of the bank’s aggregated
interest-rate risk exposure;
- evaluate the sensitivity and reasonableness of key
assumptions— such as those dealing with changes in the shape of the
yield curve or in the pace of anticipated loan prepayments or deposit
withdrawals;
- verify compliance with the board’s established risk-tolerance
levels and limits and identify any policy exceptions; and
- determine whether the bank holds sufficient capital
for the level of interest-rate risk being taken.
The reports provided to the board and senior
management should be clear, concise, and timely and provide the information
needed for making decisions.
Internal Control, Review, and Audit of the Risk-Management Process A bank’s internal-control structure is
critical to the safe and sound functioning of the organization generally
and to its interest-rate risk management process in particular. Establishing
and maintaining an effective system of controls, including the enforcement
of official lines of authority and the appropriate separation of duties,
are two of management’s more important responsibilities. Individuals
responsible for evaluating risk-monitoring and -control procedures
should be independent of the function they are assigned to review.
Effective control of the interest-rate risk management
process includes independent review and, where appropriate, internal
and external audit. The bank should conduct periodic reviews of its
risk-management process to ensure its integrity, accuracy, and reasonableness.
Items that should be reviewed and validated include—
- the adequacy of, and personnel’s compliance with,
the bank’s internal-control system;
- the appropriateness of the bank’s risk-measurement
system given the nature, scope, and complexity of its activities;
- the accuracy and completeness of the data inputs
into the bank’s risk-measurement system;
- the reasonableness and validity of scenarios used
in the risk-measurement system; and
- the validity of the risk measurement calculations.
The validity of the calculations is often tested by comparing actual
versus forecasted results.
The scope and formality of the review and validation
will depend on the size and complexity of the bank. At large banks,
internal and external auditors may have their own models against which
the bank’s model is tested. Banks with complex risk-measurement systems
should have their models or calculations validated by an independent
source— either an internal risk-control unit of the bank or outside
auditors or consultants.
The findings of this review should be reported to the
board on an annual basis. The report should provide a brief summary
of the bank’s interest-rate risk measurement techniques and management
practices. It also should identify major critical assumptions used
in the risk-measurement process, discuss the process used to derive
those assumptions, and provide an assessment of the impact of those
assumptions on the bank’s measured exposure.
