Why the FSC Denied the November 13 KOSDAQ Additional-Measures Rumor and How to Verify It

The image used in this article is not an official company image.

The claim that additional KOSDAQ measures would be announced on November 13, 2026, is a specific rumor that the Financial Services Commission (FSC) has officially denied. On November 12, the FSC stated that the claim was “not true at all.” The exact details can be checked in the official press release on the FSC website.

However, this does not mean that no market-stabilization measures have been taken. Measures related to margin loans, announced on November 6, took effect on November 9. They temporarily exempt securities firms from the collateral-ratio maintenance obligation (140%) for three months.

The FSC also announced a policy of preparing additional measures to stabilize the market if volatility increases further. However, preparing additional measures and announcing them on a specific date are two different matters.

To understand this issue, it is necessary to distinguish what the FSC denied, what policies have already been announced, and what it has said about possible future responses.

📋 1. What the FSC announced on November 12

On November 12, 2026, the Financial Services Commission issued a notice titled “Investor Notice Regarding False Information About Additional KOSDAQ Measures Circulating on the Internet and Social Media.”

The notice presented the FSC’s official position on information circulating online and on social media about additional KOSDAQ measures supposedly scheduled for November 13.

The official press release made three key points.

• First, the claim concerning “Additional KOSDAQ Measures on 11/13 (Fri)” was not true at all.
• Second, spreading unfounded rumors may constitute unfair trading under the Financial Investment Services and Capital Markets Act, and the authorities intend to take strict action if unlawful conduct is confirmed.
• Third, investors should not base investment decisions on unverified rumors and should check policy-related information through official press releases.

The important point is to understand precisely what the FSC denied.

The denial concerned the specific claim that additional KOSDAQ measures would be announced on November 13, 2026.

It did not mean that the government had canceled previously announced market-stabilization measures or declared that it would take no further action.

Furthermore, the FSC’s statement was an official confirmation that the particular rumor was false. It was not an announcement detailing a new KOSDAQ policy.

It is important to distinguish facts established by the official press release from forecasts based on those facts.

🔍 2. The scope of the denial — it does not rule out future measures

When interpreting policy announcements, it is important to separate what has been denied from what has not.

In its November 12 press release, the FSC denied the rumor that additional KOSDAQ measures would be announced on a specific date.

By contrast, its November 6 press release stated that additional market-stabilization measures would be prepared if market volatility increased further.

These two announcements do not contradict each other.

A policy of preparing responses according to market conditions describes how the authorities may respond in the future. It is different from a confirmed announcement scheduled for a particular date.

For example, an institution’s announcement that it is preparing contingency measures does not mean that those preparations will be completed or disclosed on a particular date.

The same distinction applies here.

The possibility of preparing additional measures must be assessed separately from whether the November 13 announcement rumor was true.

The FSC’s official materials provide no confirmed announcement schedule supporting the November 13 rumor. Instead, the FSC explicitly denied that specific claim.

💬 3. Why the announcement rumor may have sounded plausible

To understand the circumstances that may have attracted attention to this rumor, it is useful to examine the earlier announcement from November 6.

On November 6, 2026, the government held a joint market-conditions review meeting with relevant agencies to discuss volatility in domestic and overseas stock markets and possible responses.

On the same date, the Financial Services Commission published an official press release titled “Phased Response Measures Activated Amid Increased Volatility in Domestic and Overseas Stock Markets.”

The release described both measures relating to margin loans that had been approved for implementation and a policy for responding if market conditions became more unstable.

In particular, the statement that additional market-stabilization measures would be prepared if volatility increased further could have raised expectations of new policies.

This is because investors are likely to pay closer attention to the government’s next response during periods of heightened market volatility.

However, this is an interpretation connecting the contents of the two official announcements with market conditions at the time.

The FSC did not officially state that this wording caused the rumor.

It has not been established where the rumor originated or how it spread. There is also no basis for identifying an initial source or a particular online community as responsible.

The problem arises when a policy still in preparation is presented as though its announcement date has already been confirmed.

Distinguishing whether the original document says “prepare,” “implement,” or “confirm” can help reduce this confusion.

📌 4. Measures already implemented versus the unverified announcement rumor

One measure that was actually announced in connection with this issue was the temporary exemption from the collateral-ratio maintenance obligation for margin loans.

According to the FSC’s November 6 press release, securities firms would be exempt from the collateral-ratio maintenance obligation (140%) for margin loans for three months.

The measure took effect on November 9, 2026.

Its purpose is to prevent excessive forced liquidation following sharp declines in stock prices from further amplifying market volatility.

The key dates can be distinguished as follows.

It is also important to understand precisely to whom the 140% requirement applies.

The FSC specifically identified securities firms’ collateral-ratio maintenance obligation for margin loans as the obligation covered by the exemption.

Therefore, the announcement alone does not mean that the collateral maintenance ratios for all investors’ accounts were automatically lowered or that forced liquidation was suspended across all securities firms.

Investors need to check separately with their securities firms to determine the collateral maintenance ratios and forced liquidation criteria actually applicable to their individual accounts.

Although the official announcement specifies an exemption period of three months, this article does not convert that period into a definitive calendar end date.

The differences between the policies can be summarized as follows.

As these examples show, even materials issued by the same financial authorities can describe different things: measures already implemented, conditional plans for future action, and announcement rumors officially denied as false.

The inclusion of a specific numerical requirement does not mean that the scope of a measure can be extended to all investors.

⚠️ 5. Risks of spreading rumors as established facts

Rumors about policy announcements can do more than circulate as speculation. They may also influence the decisions of market participants.

Messages specifying a particular date can be especially misleading because they may appear to refer to an officially confirmed announcement schedule.

However, the fact that a date is specific does not make the information reliable.

In its November 12 press release, the FSC stated that spreading unfounded rumors may constitute unfair trading under the Financial Investment Services and Capital Markets Act and that strict action would be taken if unlawful conduct was confirmed.

The wording “may constitute” is important.

It does not mean that every investor who encounters an unverified message has engaged in unfair trading. The legality of an individual’s conduct cannot be equated with merely viewing information.

What matters is avoiding the dissemination of unverified information as established fact and not using such information as the basis for investment decisions.

Even an image that resembles an official document or uses a similar title should be checked against the document actually published on the government’s website.

The presence of an agency name, announcement date, or policy-related terminology in an image does not guarantee that it is an official document.

When rumors about an announcement on a specific date spread widely, giving priority to the original official document over forwarded messages is a basic principle of information verification.

✅ 6. Where to verify policy information

Financial-market policy information can be checked against official press releases published on the Financial Services Commission website.

For this issue, reading the November 12 rumor-denial notice alongside the November 6 market-stabilization announcement makes the distinction between the two releases clear.

① Find the original document in FSC press releases

Open the press releases section under “Announcements” on the FSC website and check whether the policy described on social media or in a forwarded message was actually published there.

The presence of similar wording in search results does not, by itself, establish that the same policy was announced.

Read both the title and the body of the official post.

In particular, distinguish a release announcing an actual policy from a notice warning about unverified information.

The November 12 press release was not an announcement of new KOSDAQ measures. It was a notice explaining that a specific announcement rumor was false.

② Check the publication date, responsible department, and attachments

Official posts display information such as the publication date and the department responsible. Any attached PDF or HWPX documents are also worth checking.

The announcement date and the actual implementation date of a measure are not necessarily the same.

For the margin-loan measure discussed here, the announcement date was November 6, while the implementation date was November 9.

Even if a news article or social media post emphasizes only one of those dates, reading the complete official statement helps distinguish announcement from implementation.

③ Distinguish preparations from confirmed schedules

Policy documents use expressions such as preparation, review, implementation, and continuation.

Each expression has a different meaning.

A statement that additional measures are being prepared describes a policy direction for future responses. It is not a confirmed schedule for an announcement on a particular date.

Therefore, if a social media screenshot includes wording such as “scheduled for announcement,” it is necessary to check whether the same wording actually appears in the official press release.

It is also worth examining whether a sentence taken from an earlier policy announcement has been circulated as though it were a new policy announcement.

It is important not to add assumed schedules or implementation conditions that are absent from official materials.

📝 7. Summary

The claim that additional KOSDAQ measures would be announced on November 13, 2026, was a specific rumor officially denied by the Financial Services Commission on November 12.

By contrast, the three-month exemption from the collateral-ratio maintenance obligation (140%) for margin loans, announced on November 6, was a real measure that took effect on November 9.

The FSC also announced a policy of preparing additional measures if market volatility increased further. However, that statement did not confirm an announcement scheduled for November 13.

When interpreting policy information, it is essential to distinguish officially announced facts, measures already implemented, plans for future preparation, and unverified announcement rumors.

The standard for checking related information is straightforward: consult the official press release issued by the relevant authority and examine the original wording, dates, and applicable conditions together.

Maintaining these distinctions can reduce the risk of mistaking unverified rumors for confirmed policies.
