The Korea Exchange noted that it has designated the final settlement standard bond for the government bond futures for September 2025, which will be traded starting on the 19th.
The final settlement standard bond is a standard product designated by the exchange to facilitate the trading of government bond futures based on actual government bonds. Although government bond futures are derivative products that use a government bond with a face value of 100 won and a coupon rate of 5% as the underlying asset, these government bonds do not actually exist. Therefore, the exchange designates them by combining a portion of the government bonds that pay interest every six months to resemble the underlying asset.
The standard bonds for the 3-year government bond futures for September 2025 (KTB3F2509) are three items: government bond 02875-2712 (24-12), government bond 03250-2706 (24-4), and government bond 02625-3003 (25-3).
