Enterprise Risk Management at ABN AMRO

Market Risk contd...
Interest Rate Risk
Group ALCO set limits to ensure that the potential adverse impact on trading
and non-trading earnings, due to market movements, was well controlled. Group
ALCO monitored the activities of ALCOs in the US, the Netherlands and Brazil.
Some other countries had ALCOs with centrally approved limits.
In smaller countries, all interest rate risks (trading and
non-trading) were managed within the market risk framework. Several methods were
used to monitor and limit non-trading interest rate risk - scenario analysis,
interest rate gap analysis and market value limits. Model-based scenario
analysis was used to monitor the interest rate risk positions denominated in EUR
and USD in Europe and the US.
Interest rate risk positions in other currencies and other countries were
managed by gap analysis and/or market value limits, as these positions were
typically less complex. Simulation models and estimation techniques were used to
assess the sensitivity to movements in the shape and level of the yield curve. |

Assumptions about client behavior played an important role
in these calculations. This was particularly relevant for loans such as
mortgages where the client had the right, but not the obligation, to repay
before the scheduled maturity. On the liability side, the re-pricing
characteristics of savings and deposits were based on estimates since the rates
were not coupled to a specified market rate. A statistical approach was used for
forecasting and sensitivity analyses because it best suited these products.
Although comparable with macro-economic forecasts in many ways, this approach
was based on information in individual client contracts.
The sensitivity of net interest revenue to interest rate conditions was
estimated, assuming an immediate and lasting shift of 100 bps in the term
structure of interest rates. ABN Amro's sensitivity analysis indicated that such
an upward movement would lower net interest revenue by 3.8% in the first year
after the rate jump. A downward shift would raise net interest revenue by only
1.1%, (based on the bank's positions as of 31 December 2002). This asymmetric
outcome was largely due to the historically low levels of interest rates in the
US and Europe in recent times, leading to unprecedented pre-payment behavior in
the US and leaving limited scope to adjust rates on the liability side in the US
and Europe.
Currency Risk
Currency risk was the result of investments in the bank's overseas operations
and through trading activities. In trading portfolios, exposures to exchange
rate movements were managed through market risk limits based on VAR. Short and
long positions were monitored to ensure compliance with the GRC's limits. Gains
or losses in the trading book were reported in the P&L. ABN Amro pursued various
hedge strategies with respect to investments in overseas operations to protect
itself against the adverse effects of translating foreign currency into euro,
the reporting currency:
• Ratio hedge
The Bank's BIS-ratios (tier-1 and tier-total capital as a percentage of RWA)
were protected against fluctuations in the EUR / USD rate. As capital and RWA
were subject to foreign currency translation, this was done by maintaining the
BIS-ratios for USD elements close to the overall BIS-ratios.
• Capital hedge
Investments in overseas operations denominated in currencies other than USD were
hedged selectively. Hedging was considered when the expected currency loss was
larger than the interest rate differential between the two currencies (the
interest rate differential represented the cost of the hedge). Gains and losses
on these capital exposures were taken through equity, as were the costs of
hedging.
As of 31 December 2002, an increase of 10% in the value of the euro against all
other currencies would have led to a EUR 437 million reduction in reserves, and
vice versa. On this basis, there would have been no material impact on the
Bank's BIS ratios because the ratios were hedged against changes in the EUR /
USD exchange rate.
• Profit hedge
Profits were hedged selectively to dampen the impact of currency movements on
the P&L. The decision criteria for profit hedging were similar to capital
hedging. As of 31 December 2002, all budgeted net USD profits for the years 2003
and 2004 were sold forward at a rate of USD 0.8994 per EUR and USD 0.9563 per
EUR respectively.
Liquidity Risk
Liquidity risk was an integral part of ABN Amro's business. Liquidity risk would
arise if, for example, the bank was unable to fund its portfolio of assets at
appropriate maturities and rates or was unable to liquidate a position in a
timely manner at a reasonable price.
ABN Amro managed liquidity on a daily basis throughout the 66 countries and
territories in which it operated. Each national market was unique in the scope
and depth of its financial markets, competitive environment, products and the
characteristics of its customer profile. Local line management was therefore
responsible for managing local liquidity requirements under the supervision of
Group ALCO. Each location needed to comply with local liquidity regulations.

On a day-to-day basis, ABN Amro's
liquidity management depended on the proper functioning of local and
international financial markets. The bank had established group-wide
contingency funding plans that anticipated changes in the bank's
structural liquidity under different scenarios and set out
damage-limitation procedures in case of crises. These plans could be
activated in the event of a dramatic change in the normal business
activities or in the stability of the local or international financial
markets.
As part of its liquidity management contingency planning process, ABN
Amro regularly assessed potential trends, demands, and commitments,
events and uncertainties, which might have an impact on structural
liquidity. More specifically, ABN Amro considered the impact of these
potential changes on the bank's sources of short-term funding and its
long-term liquidity planning horizons.
|
At a group level, stress testing of liquidity was conducted several times a year
and the outcomes were reported to Group ALCO. To mitigate the liquidity risk,
the bank had a liquidity buffer consisting of unencumbered liquid assets, such
as marketable securities and other short-term investments. These included Dutch
government bonds, US Treasury and US government agency paper and other OECD
government paper, which could be readily converted into cash. The size of the
liquidity buffer was linked to the outcomes of these stress tests.
At all times, on a group-wide basis, the bank maintained what it believed were
adequate levels of liquidity to meet deposit withdrawals, to repay borrowings
and to fund new loans, even under stress conditions.
The ability to sell assets (apart from marketable securities) quickly was an
additional source of liquidity for the bank. The bank's loan syndication and
securitization programmes were part of liquidity management activities. ABN Amro
believed the diversity of the banks funding sources and funding providers
increased funding flexibility and limited dependence on any source of funds. The
bank was an active participant in the capital markets, issuing commercial paper
and medium-term notes, as well as debentures, subordinated debt and preferred
stock. Diversity of funding products, market and maturity played an important
role in funding decisions.
