A Brief History of ALM1970’s» Focus on Forecasting NII
» Little IRR Management
Early 1980’s» IRR management focus on gap, duration, and simple simulations.
» Rise of inter-departmental ALCO
mid 1980’s» Formal ALM, IRR management becomes a “unit” of the bank
Late 1980’s – Early 1990’s» ALM gradually incorporated into strategic planning
» Focus expands to capital adequacy and prudent leverage
» Plain vanilla and then complex derivatives
mid – late 1990’s» ALM increasingly important in reducing performance volatility
» Stochastic valuation gains ground
» Tools grow in sophistication: customer behaviour modelling
2000’s» ALM is integrated with credit risk management, resulting in Enterprise Risk Management (ERM)
» ALM increasingly embraces economic value as the primary focus
» Liquidity Risk Management increases in importance

GAP Analysis
» Gap analysis is an asset/liability management tool used to measure interest rate risk, make funding decisions, and allocate capital along the yield curve.
» Gap is simply the post-hedge difference between rate sensitive assets and rate sensitive liabilities, bucketed into the sooner of reprice, maturity, or expected call date.
» When periodic gap is zero, net interest income is hedged against changes in interest rates. However, when there is a positive gap, earnings decline as interest rates decrease and rise as interest rates increase.
» Gap is particularly useful for balance sheets that have little optionality.

Gap Strengths
» Easy and Intuitive to Understand
» Development Costs are Small
» Can Easily Set Risk-Limit Policies
18
Gap Weaknesses
» Sizeable mismatches can be hidden in buckets as short as one month.
» Fixation on plugging Gaps to zero restricts ALM choices because many different non-zero Gap combinations immunize NII as well.
» Cannot measure risk associated with options sensitive to interest rate risk such as prepayment options or deposit intangibles.
» Gap does not provide a single index number quantifying the risk exposure of a target account.
» Assumes interest rates change by the same amount for all assets and liabilities.
» Cash flows of interest are ignored.
» Administered non-market accounts such as prime or money markets?
» Cannot manage more than one target account simultaneously.

NII Simulation: The Brute Force Approach
» A computer simulation model starts with the current balance sheet, including detailed maturity or repricing schedules and the associated rates and yields of those balances, and forecasts the income statements, balance sheets, and cash flow schedules for a series of future time periods, typically 12 to 36 months.
» This is accomplished by literally simulating the repricings, maturities, rollovers, and new business originations for all balance sheet activities of the bank!
» To generate a plausible set of financial statements, assumptions must be made about a number of important issues, including target balances, maturity schedules for new business, yield curve behavior, non-yield curve rate assumptions, and pricing assumptions for new business.

NII Simulation Strengths
» Net interest Income simulation models seek to produce their results in a dynamic or forward-looking manner whereas market value and gap models produce their results statically.
» Since simulation models are both forward looking and are interactive, they require greater emphasis on assumptions and managerial behavior.
» Therefore, simulations are unique in that they help managers anticipate future events, perform assumption sensitivity analysis, and provide a means by which managers may test the effect of different external shocks and strategies on income.
24
NII Simulation Weaknesses
» The software, hardware, and personnel requirements necessary to run an ALM model are costly.
» Simulations depend on assumptions and data analyses that place strenuous demands on the operator. Therefore, the simulation results are only as good as the analyst operating the model.
» Simulation models bog managers down in oceans of detail.
» Since simulation solves problems by trial and error, a thorough examination of current risks can be clumsy, time consuming, and labor intensive.
» ALM models can be black boxes. The internal structure of models may not reflect the bank or thrift being modeled. In addition, econometric models and relationships may become invalid with time.
25
Standard Market Value Sensitivity Measures
Market Value of Portfolio Equity (MVPE)» The market value of assets minus the market value liabilities.
Duration: Generic Description of the sensitivity of a bond’s price to a change in yield.
» Macaulay Duration: The weighted average of the time periods over which cash flows accrue to bondholders (using the percentage of the cash flows as weights) which occur at each payment time as the weighting scheme.
» Modified Duration: Duration measure in which it is assumed that yield changes do not effect the expected cash flows.
» Effective Duration: Sensitivity measure in which recognition is given to the fact that yield changes may change the expected cash flows (correlated risks).
Convexity: The rate at which duration changes due to changes in interest rates.
26
Convexity
» Duration not constant over time
» Convexity adjusts for interest rate sensitivity -‘curvature’ of price/yield relationship
» Relevant for larger moves.

Optionality: Behaviour Modelling
Where Contractual Terms May Be Varied By Custom or Implication
» Prepayment Due To Unscheduled, Part Or Full, Principle Repayments
» The Variability and Lack of Sensitivity of Non Maturity Liabilities in Terms of:
– Maturity
– Changes in Balance of Account
– Coupon or Interest Rate Repricing, or Rate Repricing Lag To Market Rates, Or The Rate Off-set Due To High Account Servicing Cost
» Call Options, Put Options
» Caps, Floors
» Changing Credit Card Balances
28
Option Adjusted Valuation
How Much Additional Risk am I really undertaking because of embedded optionality and how does it cost?» The option adjusted value (OAV) is the probability weighted market value of
all of the simulated income streams.
29
What is Option Adjusted Valuation?
» OAV is “beyond the option” in the sense that it is the expected value across a large number of possible outcomes rather than just one path.
» This market value is option adjusted because it incorporates market volatility and therefore, the changing market value of embedded options.
» Static valuation is the outcome of a single scenario where many are possible!!

Term Structure Modeling
What is likely to happen to interest rates?» Stochastic generation of interest rates allows the user to effectively forecast
the future shape and behavior of the term structure of interest rates.

How Banks Quantify IRR – Advanced Analytics
» 94% of a total population of 16 banks calculate and report NII exposure using deterministic rather than stochastic models. Therefore, minority of industry participants use stochastic income modeling despite their availability through common ALM systems.
– Most management teams do not perceive a favorable cost/benefit to stochastic income modeling
– Limited regulatory attention
– Many industry participants reported longer duration assets with embedded optionality – thereby limiting the usefulness of stochastic modeling
» 3 of 16 institutions calculate NII exposure using stochastic methods for internal comparative purposes only (results not formally reported).– Option adjusted EaR
– Multi-factor EAR
– EaR hedge Analysis
» 14 of 15 who do not use stochastic interest rate modeling perform non-parallel interest rate shocks.
» Many banks use deterministic NII modeling to satisfy regulatory requirements.
» VaR limit and compliance appears to be more prevalent amongst “market value” focused firms and are not common with “earnings focused” ones.

THE EXPANDING FRONTIER OF ALM
Current Environment
Lessons Learned Current Challenges
Need for effective firm-wide risk identification and analysis.
Review and update risk management policies, practices and governance structures
Improvement in prospective and contingency measures
Establishing firm-wide risk tolerances
Consistent application of independent and rigorous valuation practices across the firm.
Price and Value are two distinct things
“Risk” is more complicated than “Price”
Pricing should emphasize a MTM discipline
Place reasonable prices on products within HFI banking books, not just AFS and trading positions
Develop ALM/BSM “independent” sources of pricing
Consider pricing in your stress-scenarios
Effective management of funding liquidity, capital and the balance sheet.
FTP charge for liquidity
Appropriate contingent liquidity risk management
Treasury functions aligned with businesses
Informative and responsive risk measurement and management reporting and practices.
Risk metrics based one adaptive assumptions
Different perspectives on risk exposures
Stress testing not severe enough
The industry and regulatory response to the market dislocations that began in 2007 have signaled renewed interest in ALM across numerous financial disciplines. The acknowledgment of industry weaknesses and an atmosphere of very strong regulatory reform has signaled the incentive for change.
• Measure & Consolidate BS Exposure
• Establish Centralized Reporting
• Leverage Risk Mgt and BS Efficiencies
• Balance & Communicate Accounting vs. Economic Risk
• Transfer Pricing
How Risk Management is Changing» Governance: Greater emphasis on ERM principles - Movement away from “silo” based
risk management and the linking risk to capital
» Risk Assessment: Asset/Liability management needs to be more prospective in order to identify risks sooner
» Risk Quantification and Aggregation:– More disciplined valuation practices across the firm
– Convergence of market and credit risk
– Proliferation of the Enterprise Risk Management Platform
– Stress Testing – more realistic fat tail events and more holistic practices
» Risk Monitoring and Reporting:– More responsive risk management reporting practices
– Wider range of risk metrics based on different underlying assumptions
» Risk Control and Optimization:– Effective management of funding, liquidity, capital, and capital management
» Transfer pricing
» Better Liquidity risk management practices
» More efficient capital management
» Risk adjusted performance measurement

Traditional ALM Is Not Enough Anymore
» ALM is too often equated to IRR, and only IRR. It’s far more than measuring IRR (Earnings & EVE)
» The full scope about ALM is about the totality of the financial risk management of a bank. That means:- ALM = Governance + Risk Assessment + Risk Quantification + Monitoring
and Reporting + Risk Control and Optimization or ERM- Financial risks need to be modeled using instrument-level cash flows- Requires the joint modeling of financial risk across the taxonomy of risks
» Sound balance sheet management means always striving to maximize value creation and minimize value destruction» This requires a view across the taxonomy of risk types» This is an on-going process» Requires a good valuation discipline, not just an earnings focus
Traditional ALM – Interest Rate risk and
earnings/value scenario analysis

Tying rating transitions to market spreads (CreditMetrics™ approach)
MTM (i.e., a “fair value” approach)
Instrument level pricing of credit-default products
Sensitivity analysis and reporting around current and forecasted credit spreads

Conclusion
“Banks that wish to remain competitive must keep up with the latest developments in risk measurement and management…One of the most important sound practices for a banking organization is the tying of risk exposure to capital…by more clearly defining risk exposures and identifying the causes and controls for their losses, bank management can more effectively integrate decisions about risk-taking into their strategic and tactical decision-making.”
