How Long Does a Credit Rating Change Take

A credit rating change—whether an upgrade, downgrade, or new rating—does not happen overnight. The major rating agencies (Moody’s, Standard & Poor’s, and Fitch) follow formal review processes that typically stretch from one month to six months, beginning with an initial review announcement and ending with a published rating action.

The Formal Review Process

When a rating agency initiates a credit rating review, it publishes an announcement placing the issuer on “watch”—either “watch positive” (upgrade likely), “watch negative” (downgrade likely), or “watch developing” (direction uncertain). This public announcement must come before any rating action can occur; it is the formal start of the timeline.

The watch announcement gives the market warning. Bond traders and equity investors can adjust portfolio positioning before the actual rating change. Issuers can begin preparing public statements or arranging alternative financing. Employees and counterparties have time to assess the risk. The agencies argue this transparency is fairer than sudden, unannounced downgrades.

Watch Period and Issuer Comment

Once a company is placed on watch, the agencies typically allow 30 to 90 days for the issuer to provide additional information, clarify strategy, or present a rebuttal. This “comment period” is usually 10–15 days but can extend if the issuer requests more time or if the rating committee needs fresh quarterly data to complete its analysis.

During the watch and comment period, the issuer’s investor relations team meets with the rating committee, walks through the financial model, and argues why the rating should not change or should be less severe than the watch suggests. These meetings are substantive; rating committees take new data and strategic information seriously. An issuer that can credibly show improved cash flow, a successful debt refinancing, or new contracts can shift the committee’s view during the comment phase.

The rating agency meanwhile gathers additional public information: financial statements, debt covenants, analyst reports, and recent industry developments. For a large corporation, this phase typically takes 3–4 weeks.

Rating Committee Deliberation

After the comment period closes, the rating committee (usually a panel of 3–7 senior analysts) meets to vote on the rating action. This deliberation can take 1–4 weeks. The committee reviews the full analysis, weighs the issuer’s arguments, compares peer companies, and ensures the proposed rating is consistent with the agency’s rating criteria.

Controversial cases—where the committee is split or where the agency’s criteria point in different directions—can delay the vote by several weeks. Straightforward cases (an oil company with collapsing revenue) move faster. Once the committee votes, the rating action is finalized, and the agency publishes it.

The Published Action

When the rating action is published, it typically includes a detailed rationale explaining what drove the decision and whether the watch status remains, is resolved, or moves in the opposite direction. A downgrade announcement may say “watch negative resolved” if the worst has occurred, or “remains on watch negative” if further deterioration is possible. An upgrade may remove the watch entirely or shift to “watch developing.”

For a straightforward review initiated in January, expect a published action by March or April. For a complex situation (a merger, a major business restructuring, or a market-wide crisis), the timeline can stretch to six months or beyond.

Expedited Reviews and Crisis Timelines

When an event poses urgent credit risk—a surprise loss, a covenant breach, a sudden liquidity crisis, or a natural disaster—agencies can conduct expedited reviews in 1–2 weeks. These are rare and are reserved for situations where waiting for the normal cycle would be misleading to the market.

The 2008 financial crisis and the 2020 pandemic saw numerous expedited downgrades of banks and hospitality companies. In these cases, the watch period was sometimes shortened to days, and the final action followed within 1–2 weeks. However, even in a crisis, the agencies still attempt to contact the issuer for comment and hold some form of committee review before publishing.

Ratings Under Pressure: Watch vs. Outlook vs. Review

Investors often confuse different types of rating alerts. The key distinction is:

• Watch (positive, negative, or developing): The agency has opened a formal review and expects a rating action within 90 days (or sooner in a crisis). This is the strongest signal of impending change.
• Outlook (stable, positive, or negative): A qualitative view of where the rating might move over the next 1–2 years, but not a formal review. Outlook changes do not require a rating action and are less urgent.
• Review (formally initiated): The same as watch; sometimes agencies use “under review” instead of “placed on watch.”

A company placed on watch negative faces the highest urgency to respond, as the market prices in a likely downgrade within 90 days. An outlook negative is slower-moving but still signals caution.

Market Reaction Timing

A crucial point: the largest market reaction often occurs when the watch is announced, not when the rating changes. Once an issuer is on watch negative, bond traders begin selling, yields rise, and credit spreads widen. By the time the actual downgrade is published, much of the repricing has already occurred.

Conversely, if the watch is resolved without a downgrade (the agency decides not to act or upgrades instead), the market often rallies. This surprise reversal can create significant trading opportunities for those holding the bonds or credit derivatives.

Post-Action: New Watch or Resolution

After a rating action is published, the watch status is typically resolved. However, if the agency feels further changes are possible in the near term—such as after a downgrade where the company might stabilize or might deteriorate further—it may place the company on watch again or move it to an outlook (for slower-moving changes). This sets off another cycle.

A company downgraded from BBB to BB (moving from investment-grade to junk status) might be placed on watch negative again if the agency fears further downgrades, or on stable outlook if it believes the company will stabilize. The timeline for any new action then restarts.
