Korea Exchange (KRX) said on the 16th that it has designated the final settlement benchmark bonds for the June 2026 Government Bonds futures, which will be traded starting on the 17th.
A final settlement benchmark bond is a reference product that the exchange designates so that Government Bonds futures can be traded based on actual Government Bonds. Although Government Bonds futures are derivatives with a face value of 100 won and a coupon rate of 5% using a Treasury bond as the underlying asset, such a bond does not actually exist. To address this, the exchange designates a combination of certain Treasury bonds with semiannual interest payments to resemble the underlying asset.
The benchmark bonds for 3-year Government Bonds futures June 2026 (KTB3F2606) are three issues: Treasury 02750-2812 (25-10), Treasury 02250-2806 (25-4), and Treasury 02500-3009 (25-8).
Two issues were selected as benchmark bonds for 5-year Government Bonds futures June 2026 (KTB5F2606): Treasury 02500-3009 (25-8) and Treasury 02625-3003 (25-3).
The benchmark bonds for 10-year Government Bonds futures June 2026 (KTB10F2606) are two issues: Treasury 03250-3512 (25-11) and Treasury 02625-3506 (25-5), and the benchmark bonds for 30-year Government Bonds futures June 2026 (KTB30F2606) are two issues: Treasury 02625-5509 (25-7) and Treasury 02625-5503 (25-2).
The spot yields by final settlement benchmark bond are calculated by the Korea Financial Investment Association at 11:30 a.m. and 4 p.m. each day and published on the Korea Financial Investment Association website, the Koscom Check terminal, and elsewhere.
