Risk Management in Financial Modeling
Financial models were widely used
by companies as early as 2008. However, with the severity of the disaster in
2008, it forced financial institutions to reconsider their modeling approach.
Many of the assumptions in the financial model have been modified to reflect
lessons learned during the Great Recession. One of those lessons was about risk
management. After the fall of 2008, modeling the risk of all the financial
losses it caused has become an essential part of any financial model.
In this article, we will
understand in detail why risk management is important for a financial modeler:
Financial
Modeling is an important part of the business. Risk management and financial
modeling are two key concepts in the field. Risk Management involves
monitoring, controlling, and mitigating risks in a business. It encompasses
analysis of external risks such as economic, market, and geopolitical factors
that can have a direct effect on the firm's profitability or asset values.
Financial modeling is an essential part of risk management because it provides
detailed predictions about the future financial performance of the company.
How
Does Risk Management Define By Financial Modeler?
In
general, the risk is defined as the possibility of any loss or injury. However,
from a financial point of view, the risk is defined as the deviation from the
average. Therefore, risk management involves understanding the possible links
between the consequences of an event. The whole exercise is to determine the
likelihood of a certain negative event occurring in the future. Once the
probability is established, a decision is made as to the impact of the event.
Simply
put, financial modelers define risk as the probability of an event multiplied
by the event impact.
Risk =
Probability x Monetary Impact
Common
Approaches Of Risk Modeling
Statistical
Risk Modeling
It is a method
that can be used even when the root causes of the risk are unknown. For
example, firms know the exact reasons why commodity prices rise. In fact,
rising or falling commodity prices are driven by a number of factors that may
be too difficult to express in cause and effect terms.
However, when a
company does statistical analysis, it can find links between rising prices of
commodities and other variables. These correlations act as close proxies since
the causal relationship is unknown. The reference values can then be
considered as early indicators of risk modeling. The basis of scenario analysis
is statistical risk modeling. Because the script is nothing but an input group.
Statistical risk modeling is very important to identify the combinations in
which these inputs reside.
Mathematical
Risk Modeling
There are many
instances where the financial modeler is well aware of the cause-and-effect
relationship that makes the risk. In such cases, detailed statistical modeling
is not required. In such cases, financial modelers should develop a smaller
sub-model to model the relevant risks. This sub-model output should then be
presented as an input to the main financial model. The problem is that the
modeler's job here is to create formulas that mimic reality. That's why models
are only as good as they were made by a financial modeler!
Computational
Risk Modeling
There
is a relatively new area of research, called computational risk modeling,
which uses the power of computers to generate millions of scripts in
nanoseconds and provide information on various inputs.
Financial
modeling is a kind of economic analysis that predicts or specifies the
financial outcomes of a particular business decision. It usually includes
estimating the change in market value, revenues, and costs for decision
alternatives.
So,
what does it take to become a financial modeler? The Financial
Modeling course online explores how to use the tools available in Excel
including graphs and charts, formatting and conditional formatting, functions,
data tables, and data ranges.
