Asset Liability Management
Asset Liability Management (ALM)
Traditionally and till recently, banks used "Accrual Accounting" for all their assets and liabilities in their balance sheet. They raise liabilities in the form of capital, including reserves, deposits from public in various forms, local external borrowings, refinances, on different terms and for varying periods and invest these funds to acquire assets.
Again, such assets are in the form of cash, readily encashable securities, balances with banks foreign exchange, Govt. securities in accordance with statutory liquidity requirements and as part of their own investments, and loans advances to public which ofcourse is the primary objective of the commercial banks
The spread between yield on their assets and the cost of their liabilities represents their margin. This margin otherwise known as Net Interest Margin, together with various other income such as commissions, profit on exchange, remittance fees, non-fund business income, etc. after reckoning all costs including staff and over heads represents their overall profits
During the administered interest rate regime the Net interst margin were so high that the fluctuations in interest rates did not really bother the banks as the spread was quite high. Mis matches in assets and liabilities prior to 1970s tended not to be a significant problem. In most developed countries interest rates witnessed only a modest fluctuations. Losses due to assets-liabilities mis matches were negligible. Many banks managed with mis-matches, at times deliberately as yield curves were generally upward sloping. They could earn a spread by borrowing short and lending long.
Let us assume the case of a bank with a share capital of 20 crores, raises 1000 thousand crores @ by way of liabilities at 3% per annum and lends the same to their good clients for 5 years @4%. For convenience, let us also assume interest rates are annually compounded and interst accumulates upto the due date of the obligations. The transaction overall appears to be profitable the bank will be earning a spread of 100 basis points (1%). That is about 10 crores.
The risks in the above transaction are
1. Interest rate fluctuation.
2. Every year end, bank should find new finacing source (Good borrowing customers)
3. Terms of such renewal un known.
4. Market liquidity at the time of raising such funds then.
5. Deployment of annually repaid instalments(Sourcing good customers, acceptable terms, lead time for processing, interest rate etc)
6. Default.
Taking first three of the risks indicated. Let us suppose that at the end of the first year, of the 5 year term loan, the interest rate moves up by 3 for enabling bank to fund the outstanding under the loan to the extent of 800 crores by raising the liability at a cost of 5%. The loan,however will carry the contracted interest rate @4%. The one percent positive spread will become negative to the extent of 1%. Under the accrual accounting system, the transaction would still appear profitable, inspite of the moved up interest rate.
Asset(Loans)---------1000 crores into 1040---------1040 crores
Liability-----------1000 " into 1030----------1030 "
Rs.10 crores profit made up of interest spread.
It is only the market value accounting that recognizes the banks real predicament according to which the position would appear as below.
Asset ----- 1000into(1040)
-------------
1000 into(1050)
It can be seen that from the market value perception, the bank had lost nearly 5 crores and the system clearly brings out the position whereas the accrual system hides the reality, ofcourse not for ever. At the end of the loan period, the real position will emerge and the bank can remain under false comfort during the period of the loan. The spread loss however is mitigated by the redeployment of 200 crores repaid to be lent at 6% or more. This will be for the second year.
To illustrate the misery of unpreparedness of the interest rate risk management the classic cases are those of the mutual funds in 1980s. They raised long term liabilities at fixed rates and deployed them with a spread that looked attractive when the deployments took place. In the fallen interest regime, the investors were still to get the almost guaranteed return whereas the yield on the funds deployed varied. Yin the fallen interest rate scenario they could not realize the guaranteed the interest.
Several mutual funds deployed the funds raised under fluctuating interest bearing investments. Mis matches in liquidity funded on short term basis, with interest hovering around quite high. The short term rates were in good Teens and the funding cost virtually caused collapse of several mutual funds.
Classic example is the case of EQUITABLE, a mutual life insurance company in U.S. This company had sold number of long term GIC contracts, guaranteeing yields @16%. In 1980s the short term interest yield curve got inverted and the short term rates were hovering well above 10% and then on around Teens. Equitable thought that they could raise huge resources and deploy in short term to take advantage of the spiking Short term rates.
Each GIC contract was for a minimum of Us#100 million for 10 years@16%. As ill luck would have it the short term rates nose dived and came down drastically. Repayments coming from the short term loans could not be redeployed at any rate near 16% guaranteed. The result was colossal loss booking and ultimately default in meeting the obligations. Equitable had to be de-mutualised and sold to Axa group
In India too such misery occurred and perhaps part of the problems faced by Unit trust of India could be on account of costly resources, guaranteed yield to investors, poor decisions on deployment, crash of stock market prices, mis matches and fluctuated interest rates both on short term and long term. Public and investors remained in darkness partly due to accrual system of accounting which did not bring to light the real problem.
The traditional approach to accounting do not bring out the hidden dangers as under the system neither the value of the fall nor the value of the liability rises. The impact of on the assets and liabilities due to interest rate fluctuations, delay in payments, liquidity in the market, redeployment scope and acceptable terms etc could, individually. collectively or by combination be very severe on the institution which may even collapse. This is so because such staggering losses have to fall on the Capital which size is disproportionate to the size of the liabilities or assets.
Basle recommendations focuses itsattention mainly on the size of capital in banks. Already banks are struggling to raise the minimum capital needs and there is going to be additional capital to be brought in to cover Market risks and Operational risks. Under this circumstance it will be unwise to lose the existing capital by risk which are anticipated particularly the Asset-Liability risk
Asset-Liability risk is therefore a leveraged risk. The narrowing of the difference between liabilities and assets which may fail to move in tandem can cut into the Capital which is disproportionately low compared to the size of the balance sheet total. A small percentage of change in assets and liabilities can culminate into larger percentage of depletion of capital funds
Asset-liability risk is leveraged by the fact that the values of assets and liabilities each tend to be greater than the value of capital. In this example, modest fluctuations in values of assets and liabilities result in a 50% reduction in capital.
ALCO(Asset Liability Management)
Managing Interest Rate risk through ALCO
Banks can have a policy to measure and manage the rate sensitivity position to ensure that in the long run the earning power of the bank is retained. This challenge involves classifying all Rate Sensitive Assets and Rate Sensitive Liabilities known briefly as R S A and R S L. These will have to be analysed as a percentage to arrive at an acceptable Ratio. The G A P(RSA-RSL) to Equity Ratio to be arrived at and ensured that it is in conformity with the objective. The GAP position may be reviewed based on
Less than 15 days
15 to 30 days
30 days
60 days
90 days
180 days
12 months
1 to 2 years
More than 2 years
While reviewing the GAP there should be greater emphasis on the Change in Net interest Income that could arise from the possible fluctuation in the interest rates, changing account volumes and time. Bank may also resort to SIMULATION, by estimating changes in interest income due to changes in interest rates say 1%, 2@%, 3% increase or decrease and constant rate scenarios
To measure the Risk to Market value of Equity, bank may review all Long term fixed rate assets and price volatility of the investments using the DURATION ANALYSIS. Bank may get a feel of the estimated depreciation in the market value, if the rise in interest rate is say by 300 basis points (3%) in comparison to banks Equity capital. Bank may also compare the Long term assets to Short term volatile Liabilities.
Rate sensitive assets could be securities purchased under agreement to sell, all loans maturing with in a given time frame, all Securities maturing with in a given time frame, all loans with floating interest rates, all securities with floating interest rates, Principal payments on all securities that are to be received using the current prepayment speed assumptions and on all the loans that are to be received if expected prepayments are large enough.
Rate sensitive Liabilities include
- All securities under agreement to re purchase
- Certificate of deposits
- Demand deposits(The practice and experience such as C.D/S.B balances being classified as part demand deposits and part time deposits that is core/volatile say 40%, 60% respectively)
- Sundry creditors, outstanding payments, Drafts, T.Ts payable
- All other liabilities like debentures, floating rate deposits etc.
The other relevant classification is also given below
- Variable interest sensitive assets
- Variable interest sensitive liabilities
- Fixed interest assets
- Fixed interest liabilities
To overcome some of the disabling features, banks may resort to SIMULATION modeling
Simulation is to measure the risk to net income by projecting the future composition of banks assets and liabilities and applying different interest rate scenarios. Bank may consider varying the interest rate spreads(BASIS RISK) between deposits, c.d. rates call rates, loans and advances, investments. They can also take into account prepayment options, interest rate caps. As an outcome of simulated scenarios the bank may plan out stragies, duly incorporating the assumptions.
Simulation model can help assess short term(365 days---2 years) interest rate risk. It is not advisable to rely upon this for risk assessment for longer term repricing imbalances. For such long term repricing imbalances and for risk identification, a very thorough subjective analysis of the balance sheet items and duration analysis of the investment portfolio to be resorted to evaluate long term fixed rate positions.
Risk limit, as a ALM policy, may be set, say for a period of 1 year time frame as under.
RSA to RSL | ------- | % to % |
Gap | Less than---% | |
Gap to Equity | Less than---% |
The GAP
The entry of into liberalized environment and entering into floating rate regime with PLR remaining as basis, presupposes preparation of credible CASH FLOW statement at periodic intervals and analyzing the same with a view to ensuring the desired NET INTEREST MARGIN. The rate sensitive assets and liabilities, floating-variable rate assets and liabilities when aggregated,reckoned and slotted into Time buckets lend scope to determine the GAP.
Gap analysis from the compiled data should be used to measure the risk to Net interest income arising from the re-pricing of assets and liabilities over time. The bank should study the net re-pricing imbalances(RSA-RSL) in the cumulative time frames of 90, 180, 365 days while measuring the risk based upon the size of imbalances, how long the re-pricing imbalances will remain open and the potential movement in interest rates. The G A P report will indicate the timing and sources of interest rate risk.
However it should be borne in and that for all time to come the GAP reports do not give total immunity from interest rate risk. The GAP cannot locate the significant risk hidden in re-pricing time frames of the GAP reports.
The GAP does not capture the fresh loans, deposits and other business entered. Option features in the Loans deposits are not readily determinable. Interest rates on assets and liabilities move in different magnitude and velocity.
Lastly Interest rate risk limits say for a one year time frame may be indicated as exampled below.
-365 days change in market interest rates | Net int change as a % of Net.int.income | |
100 basis points | >--10% | |
150 | >--15% | |
200 | >--20% | |
300 | >--20% | |
0 | >-10% | |
+ 100 | > 1 to 2.5% | |
+ 150 | > --15% | |
+ 200 | > --20% | |
+ 300 | > --20% |
The management of interest rate risk may be through investments, loans re- pricing, deposit pricing. ALM policies, by and large, should be based on how the interest rate risk affects overall business risk. Business risk is made up of Liquidity risk, Credit risk, Interest rate risk and Capital risk. ALCO should aim at maximizing the earnings and net worth and minimizing the connected risks. ALCO should also review the methods for managing the Balance sheet items related to increasing/decreasing assets, changing liability structure, Balance sheet structure, maturity and growth and hedging.
Such a strategy to be based on current level of risk, time frame and prevailing interest rate environment. If it is perceived that interest rate may decline, bank may attempt to reduce fixed rate liabilities and at the same time step up fixed rate assets. If bank perceives interest rate hike, they should endeavour to increase the fixed rate liabilities to longer maturities, while acquiring variable rate assets to enlarge net interest margins
