Prevents Risk in the Money Market: Understanding Value at Risk (VAR) with Historical Methods

In the financial world, risk is an inevitable factor. Especially in money market transactions, interest rate fluctuations and dynamic market conditions can have a significant impact on profitability. To minimize potential losses, banks and financial institutions need to implement effective risk management strategies. One of the commonly used methods is Value at Risk (VAR), especially with the approach historical method.

The historical method VAR utilizes the actual historical data of market factors to determine the distribution of changes in portfolio values. This data includes changes in interest rates, exchange rates, and other factors that are relevant to money market transactions. By analyzing historical data during a certain period, for example the last 12 months, this method can predict the potential maximum loss that may occur in the portfolio.

How is the Historical Method VAR Works?

The historical method VAR is a widely used approach in risk management. It involves the following steps:

Data Collection:

This method begins by collecting historical data changes in portfolio values over a certain period of time. For example, banks can collect data on changes in interest rates for the last 12 months.

Calculation of Actual Portfolio Value:

The actual value of the portfolio is calculated based on changes in historical data. For example, if the deposit rate rises, the actual value of the portfolio will increase (gain), and vice versa.

Ordering Actual Value:

The actual value of the portfolio obtained is sorted from the largest (gain) to the smallest (loss).

Determine VAR:

Based on the level of trust chosen, for example 99%, this method will determine the VAR value. VAR represents the maximum loss value that may occur in the portfolio within a certain period of time (for example, one year) with a certain level of trust.

Examples of Application of Historical Method VAR:

In the example above, money market risk analysis produced a VAR of Rp 351,942,500.00 with a confidence level of 99%. That is, banks have 99% of belief that losses experienced in the next year will not exceed that value. Only 1% of the likelihood of losses will exceed that number.

The Advantages and Disadvantages of the Historical Method VAR:

The historical method VAR offers several advantages, including:

Ease of Implementation:

This method is relatively easy to understand and implemented because it only requires the available historical data.

Relatively Simple:

Compared to other VAR methods, such as the Monte Carlo method, historical methods are more easily applied and require fewer computing resources.

However, this method also has weaknesses, namely:

Dependencies in Historical Data:

This method is very dependent on the available historical data. If historical data is not representative or does not reflect current market conditions, the resulting VAR results can be inaccurate.

Limitations in Predicting Future Risks:

Historical methods are less effective in predicting risks that arise from events that have never happened before.

Conclusion:

The historical method VAR is a valuable tool for measuring and managing risk on money market transactions. However, it is important to understand its limitations and consider other var methods to get a more comprehensive picture of the risks faced. By understanding risks and implementing effective risk management strategies, banks and financial institutions can increase their stability and profitability in the dynamic money market.

Recommendations:

To get the most out of the historical method VAR, the following recommendations can be made:

Use a long period of historical data: Using a long period of historical data can help to reduce the impact of outliers and provide a more accurate picture of the risks faced.
Consider multiple scenarios: Considering multiple scenarios can help to identify potential risks and provide a more comprehensive picture of the risks faced.
Use other VAR methods: Using other VAR methods, such as the Monte Carlo method, can help to provide a more comprehensive picture of the risks faced and reduce the reliance on historical data.

By following these recommendations, banks and financial institutions can increase their stability and profitability in the dynamic money market.

Future Research Directions:

There are several future research directions that can be explored to improve the historical method VAR:

Developing new VAR methods: Developing new VAR methods that can provide a more comprehensive picture of the risks faced can help to improve the accuracy of risk management.
Improving the accuracy of historical data: Improving the accuracy of historical data can help to reduce the impact of outliers and provide a more accurate picture of the risks faced.
Considering multiple scenarios: Considering multiple scenarios can help to identify potential risks and provide a more comprehensive picture of the risks faced.

By exploring these future research directions, banks and financial institutions can increase their stability and profitability in the dynamic money market.

Conclusion:

In conclusion, the historical method VAR is a valuable tool for measuring and managing risk on money market transactions. However, it is important to understand its limitations and consider other var methods to get a more comprehensive picture of the risks faced. By understanding risks and implementing effective risk management strategies, banks and financial institutions can increase their stability and profitability in the dynamic money market.
