Important Notice Regarding Margin Transaction Margin Calls and Restrictions: August 18th, 2025

Tokyo, Japan – August 18, 2025 – Japan Securities Finance Co., Ltd. (JSF) has today, August 18th, 2025, at 07:39 JST, published an important update concerning margin transaction margin calls and the implementation of specific stock restrictions. This announcement provides crucial information for market participants involved in margin trading.

The document, titled “貸借取引銘柄別増担保金徴収措置の実施等について(8/18) – 銘柄別制限措置” (Regarding the Implementation of Margin Call Measures by Margin Transaction Stock – Stock-Specific Restriction Measures), details the measures taken by JSF for specific stocks.

Key Information and Implications:

While the specific details within the PDF are not accessible for direct content extraction, the title clearly indicates that JSF is taking action related to:

  • Margin Call Measures: This suggests that for certain listed securities, JSF has initiated or will be initiating the collection of additional margin funds. This is typically a proactive measure taken to mitigate risk when trading in a particular stock becomes volatile or poses a heightened risk to the lender. Investors who have borrowed funds to purchase these securities may be required to deposit additional funds into their accounts.
  • Stock-Specific Restriction Measures: The announcement also points to the imposition of specific restrictions on trading for certain stocks. These restrictions can take various forms, such as:
    • Increased Margin Requirements: A higher percentage of the transaction value might need to be deposited as margin.
    • Limitations on Short Selling: The ability to initiate new short sales may be curtailed.
    • Ceilings on Borrowing: The maximum amount of funds that can be borrowed against specific stocks for margin trading might be reduced.

Purpose of These Measures:

Such measures are standard practice within the financial markets and are implemented by entities like JSF to:

  • Maintain Market Stability: By managing risks associated with highly leveraged trading in individual securities, JSF aims to prevent systemic risks and maintain overall market order.
  • Protect Investors: These actions are designed to safeguard both JSF and the investors participating in margin trading from potential significant losses that could arise from extreme price movements.
  • Ensure Orderly Trading: By managing the supply and demand for borrowed securities, JSF contributes to more orderly and predictable trading environments.

For Investors:

It is highly recommended that all investors engaged in margin trading, particularly those with positions in the stocks mentioned in JSF’s announcement, thoroughly review the official publication. Understanding the specific restrictions and margin requirements is essential to:

  • Manage Existing Positions: Ensure that accounts remain compliant with the updated margin requirements to avoid forced liquidation of positions.
  • Plan Future Trades: Make informed decisions about initiating new trades or adjusting existing ones, considering the potential impact of the announced measures.

Japan Securities Finance Co., Ltd. remains committed to the sound functioning of the securities lending and borrowing markets. This proactive communication serves to keep market participants informed of important operational adjustments.
