Market risk is the exposure to loss that comes from movements in market rates and prices rather than from anything specific to a single issuer. US disclosure rules give the term a working shape rather than a one-line definition: they break it into four categories of exposure and require a registrant to quantify each one it is materially exposed to. In portfolio theory the same phrase names the risk that diversification cannot remove, which is a different framing of the same idea and sits in unsystematic risk.
The Four Categories, and Where They Are Written Down
The Securities and Exchange Commission’s disclosure item on the subject defines the exposures a registrant has to identify. Primary market risk exposures means the following categories of market risk, interest rate risk, foreign currency exchange rate risk, commodity price risk, and other relevant market rate or price risks such as equity price risk, and within each of those categories the particular markets that present the primary risk of loss to the registrant (17 CFR 229.305, Instructions to paragraph 305(b)).
The second half of that instruction is the part that gets skipped. Naming the category is not the disclosure. The rule asks which markets inside the category actually carry the exposure, and the item itself works the example: a registrant materially exposed to foreign currency risk and most vulnerable to changes in dollar to yen, dollar to pound and dollar to peso rates should disclose those exposures, and one most vulnerable to changes in short-term US prime rates should disclose that (the same instruction).
Trading and Non-Trading Are Reported Apart
Before anything is quantified, the instruments get sorted. Registrants shall categorize market risk sensitive instruments into instruments entered into for trading purposes and instruments entered into for purposes other than trading purposes, and within both portfolios separate quantitative information is presented, to the extent material, for each market risk exposure category (17 CFR 229.305(a)(1)).
Trading purposes has a definition attached. For purposes of these instructions, trading purposes means dealing and other trading activities measured at fair value with gains and losses recognized in earnings (17 CFR 229.305, General Instructions to paragraphs 305(a) and 305(b), instruction 7).
That wording is the same test the accounting standards apply to a security held for short-term profit, so the two rulebooks land on the same population from different directions, the classification worked through in trading securities.
The Three Ways a Registrant May Show It
The item does not prescribe one presentation. It offers three, and a registrant may use one for everything, or a different one for the trading and non-trading portfolios, or a different one for each risk category within each portfolio (17 CFR 229.305(a)(1)).
- Tabular presentation of information related to market risk sensitive instruments, including fair values and contract terms sufficient to determine future cash flows, categorized by expected maturity, with a description of the table’s contents and the assumptions behind it.
- Sensitivity analysis disclosures expressing the potential loss in future earnings, fair values or cash flows resulting from one or more selected hypothetical changes in interest rates, foreign currency exchange rates, commodity prices and other relevant market rates or prices over a selected period, where the magnitude of the hypothetical change may differ among and within categories, with a description of the model, assumptions and parameters.
- Value at risk disclosures expressing the potential loss over a selected period with a selected likelihood of occurrence, reported for each category as the average, high and low amounts or the distribution of those amounts for the reporting period (17 CFR 229.305(a)(1)).
The three are not interchangeable readings of one number. A table reports positions, a sensitivity analysis reports what a stated shock would cost, and value at risk reports a loss with a probability attached. Only the third carries a likelihood, which is why comparing a value at risk figure with a sensitivity figure across two companies compares nothing.
Where a Firm Meets the Disclosure
It is a standing quarterly item, not an annual one. Part I of Form 10-Q carries quantitative and qualitative disclosures about market risk as Item 3, under Item 305, and the form’s other Part I contents are set out in Form 10-Q.
For interim periods the requirement is framed as change rather than restatement. Where interim statements are included, the discussion enables the reader to assess the sources and effects of material changes in the Item 305 information from the end of the preceding fiscal year to the date of the most recent interim balance sheet (17 CFR 229.305(c)).
Market Risk and the Risk That Cannot Be Diversified Away
The valuation literature uses market risk as a synonym for systematic risk, the risk common to all risky securities that diversification cannot eliminate, and beta as its measure. That reading, the line it draws against company-specific risk, and the model built on it are set out in unsystematic risk, beta coefficient and the CAPM equation.
The two uses do not conflict, and they are not the same job. The valuation sense prices an exposure into a discount rate. The disclosure sense makes a filer say which rates and prices it is exposed to and what a move in them would cost. A company can be materially exposed under the second while its beta says little about the first.
Common Questions
Interest rate risk, foreign currency exchange rate risk, commodity price risk, and other relevant market rate or price risks, with equity price risk given as the example of the fourth.
In valuation, yes, the terms are used for each other. In securities disclosure the word is doing a narrower job, naming the rate and price exposures a filer has to quantify rather than a component of an expected return.
Registrants filing under the Commission’s rules, in the annual filing and again each quarter, where the quarterly disclosure addresses material changes since the prior fiscal year end rather than repeating the whole analysis.
Accountably places trained offshore accountants and tax preparers inside US CPA and EA firms, and a firm can grade a real block of that work on its own files through a trial task before any client file moves.
