Daily Risk Management Operations

This work comes up in managing market risk limits, where the risk management department checks limit usage every day and reports it to management.

What it is for

This work is carried out by the risk management department. It measures risk every business day and reports how much of each limit is used. Traders and unit heads in the trading units (front office) receive those reports and must explain the reason and the response when a limit is exceeded.

The size of market risk and counterparty credit risk (the credit risk of the other party to a trade) changes every time the market moves. The board of directors decides what kinds of risk to take and how much, and allocates matching allowances to each trading unit¹. These allowances are called risk limits. Daily risk management operations check every day that risk is being taken within the allocated limits, so that management can act when a limit is about to be exceeded.

The departments of a financial institution are grouped into the front office (sales and trading), the middle office (risk management and similar functions), and the back office (operations and settlement). The roles of each and the reasons for separating them are covered in Front, Middle and Back Office Roles. The center of this work is the part of the middle office that monitors risk and limits: the risk management department. The source here is the examination manual of the US Federal Reserve Board (1998; the "examination manual" below). It requires the staff responsible for measuring risk, monitoring limits, and validating valuation models to be independent of the trading and sales functions². For the risk management department to act as a check on the front office, the work of measuring risk and preparing reports must be independent of the front office³.

The flow of the risk management department's work

The risk management department's work runs from checking data to reporting, in the order below.

Figure description

The figure shows how the risk management department takes in and checks positions and market data, measures risk, compares it with limits and works out usage, and reports. The report is received by the traders and unit heads in the trading units, and by management and the board. Reporting and approval when a limit has been exceeded or is likely to be are not in the figure; they are covered in the section "What happens when a limit is exceeded."

The steps are as follows. The parentheses show the department in charge of each step and the source used for it. The sources are the examination manual and the Comprehensive Guidelines for Supervision of Major Banks, etc. of the Financial Services Agency (FSA) (the "major banks guidelines" below).

1. Take in positions and market data, and check them by reconciling them with other records (risk management department; the examination manual)⁴.
2. Measure risk (risk management department; the examination manual)².
3. Compare risk and profit and loss with the limits and work out how much of each limit is used (risk management department, independent of the trading units; the examination manual)⁵.
4. When a limit has been exceeded or is likely to be, report to the designated manager and decide whether to approve the excess or reduce the position (front office, risk management department, and management; the major banks guidelines)⁶.
5. Report risk and limit usage to traders, unit heads, management, and the board (risk management department; the examination manual)⁷.

Which measures are produced daily and which weekly or monthly differs by institution. Under the examination manual, stress tests assuming exceptional markets are to be run periodically, separately from daily risk measurement, and examiners also look at how often stress tests are run⁸. The manual also says that the frequency of reports to management should match the volume of trading². For counterparty credit risk, guidance issued by the US banking supervisors in 2011 (revised in June 2026) calls for reports to the board and senior management at a frequency that matches the size of the exposures and the complexity of the transactions⁹.

Checking positions and market data

Calculating risk starts with passing the trading positions to the risk measurement system. Under the examination manual, positions are to be passed accurately, and reconciliations are to be performed across all products to confirm the integrity of the data, including new products monitored apart from the main processing systems⁴. The manual also calls for controls on each stage (passing positions, market data, key assumptions and parameters, the risk calculation, and reporting), with each stage subject to internal validation and independent review¹⁰.

Independence from the front office also matters in how data is obtained. In a 2019 Bank of Japan training document, the risk management department is to take data directly rather than through the front office, and when it uses front-office data, it is to verify that the data is reasonable¹¹. The records used for reconciliation of positions are those in which the back office has checked the trade details and fixed the positions and profit and loss through settlement and accounting¹².

Positions recorded outside the main processing systems are prone to manual errors when they are entered into the risk measurement system. The examination manual recommends automated data feeds to the risk measurement system for such positions as well, to reduce manual errors¹³.

Measuring risk and monitoring limits

The risk management department calculates several measures side by side and compares them, rather than relying on a single one. VaR has limitations as a statistical measure. For this reason, the FSA's supervisory guidelines for major banks call for banks to strengthen their management methods by combining stress testing with a variety of measurement methods, such as gross positions like the notional amount and changes in volatility¹⁴. The table below lists commonly used measures and the pages on this site that explain how to calculate them.

The measured values are compared with the limits. Limits include position limits placed on interest rate sensitivities or notional amounts, risk limits placed on estimated loss measures such as VaR, and loss limits. A point of focus in the major banks guidelines is whether the board of directors sets the basic approach to these limits and to stress testing, and whether the board or a similar body reviews them at least once each period¹⁵.

To notice a problem before a limit is exceeded, an institution can set alarm points below the limit. An alarm point is placed at, for example, 50% or 75% of the limit, and crossing it triggers a warning or a discussion of whether to revise the investment policy¹⁶. Consider a hypothetical example in which a financial institution places the limits below on an interest rate trading desk.

On this day, VaR is 800 million yen, above the alarm point of 750 million yen, so the risk management department tells the desk head and they discuss how to manage the position from here. The cumulative loss is 200 million yen, 40% of the 500 million yen limit. If the desk had a profit since the start of the month, usage of the loss limit would be 0.

In the US supervisors' guidance, credit limits for each counterparty are also monitored by updating exposures at least daily and comparing them with the limits¹⁷.

Under the Cabinet Office Order on Financial Instruments Business, etc., a securities firm tracks every business day the market risk equivalent and the counterparty risk equivalent used to calculate the capital adequacy ratio under the Financial Instruments and Exchange Act¹⁸. Under the Comprehensive Guidelines for Supervision of Financial Instruments Business Operators, etc., supervisors check whether the director responsible for risk management knows these amounts every business day¹⁹. In proprietary equity trading, intraday trading is also managed so that it stays within the amount of market risk the firm can accept. The same guidelines accept approximate methods, such as multiplying the size of the position at each point during the day by an intraday stop-loss range set within the firm²⁰.

What happens when a limit is exceeded

The response to a limit excess is decided in advance. A point of focus in the major banks guidelines is whether the bank has clearly set the reporting lines to managers and the authority (policies and procedures) for when position limits, risk limits, or loss limits are exceeded or are likely to be exceeded⁶.

There are two ways to set the rules: hard limits and soft limits. A hard limit requires the position to be reduced or closed by force once the limit is exceeded. A soft limit requires the view on the market to be reconsidered and the investment policy to be discussed once the limit is exceeded, and does not always mean the position is reduced¹⁶. Around 2019, Japanese financial institutions often used soft limits for market risk. With a soft limit, the market can move and losses can grow while the discussion is going on. With a hard limit, the position must be reduced as soon as the limit is exceeded, so once the alarm point is crossed, the institution can agree in advance on what to do if the limit is exceeded²⁴.

Consider a hypothetical example in which the VaR limit of the interest rate desk at Bank Z is 1 billion yen and VaR on a given day is 1.1 billion yen. Usage is 1.1 ÷ 1 = 110%, and the limit is exceeded by 100 million yen. If the limit is a hard limit, the position is reduced or closed; if it is a soft limit, the investment policy for the period ahead is discussed. When deciding under a soft limit whether to keep or reduce the position, reducing it resolves the excess, but the part that was reduced does not receive any profit if the market later moves in the position's favor. If the position is kept without reducing it, losses may grow if the market moves against it.

Under the examination manual, the procedure for exceeding a market risk limit is as follows⁵.

1. Before exceeding a limit, the trader obtains at least oral approval from senior management independent of the trading area.
2. Approval of the excess is given in writing, and the record is kept.
3. Senior management deals with repeated excesses and departures from approved trading strategies.

Under the examination manual, when an excess occurs, traders, risk managers, and senior management are to be able to explain the reasons for it⁴. When a loss limit (stop-loss) was reached, senior management typically responded, and the position was hedged or liquidated²⁵.

Who decides to close a position differs by institution. A 2019 Bank of Japan training document gives several examples. In one, the risk management department only advises and the front office closes the position on its own responsibility. In others, the risk management department has the authority to close it, the board or the management committee decides, or the parties involved agree on it together²⁶.

Reporting to the front office and management

The risk management department reports measured risk and limit usage to traders and desks, unit heads, senior management, and the board. Under the examination manual, reports are to be issued regularly with the detail and frequency suited to each level⁷, and procedures are to set out which reports reach whom through which channels in the organization⁵.

Reports to management cover the amount of risk and the status of any limit breaches. When market changes make a limit excess likely, the department reports and discusses it without waiting for the regular report³. Whether the bank reports to senior management as needed, in addition to regular reports, is also a point of focus in the major banks guidelines²⁷. In the 2019 Bank of Japan training document, reports prepared by the risk management department are to go directly to the board, not through the front office¹¹.

Reports on counterparty credit risk include concentration analysis and stress test results, to show how much could be lost in severe markets. When weaknesses or limitations of the measurement methods affect the accuracy of the risk figures, the reports explain them as well⁹.

Departments involved and their roles

The following departments are involved in daily risk management operations.

Internal audit also checks that the front office is not involved in measuring risk²³. Some institutions place front, middle, and back office staff within the same department. When a separate department is hard to set up, the institution finds other ways for the middle and back offices to check the front office, such as assigning the roles to independent officers who have no reporting line to one another. Internal audit makes up for weaker checks at the level of the executive or department head who oversees the unit³¹.
