GPW Benchmark Launches New Government Bond Index

2026-08-17 17:03:16

GPW Benchmark announces the launch of the new GPWB-B3Y index, which becomes part of the Family of Government Bond Indices. The index covers government bonds with a remaining maturity exceeding three years and provides market participants with an additional tool for monitoring developments in the Polish government debt market. The index is based on TBSP reference prices determined on the Treasury BondSpot Poland market.

The indices belonging to the Family of Government Bond Indices reflect market conditions and trends on the wholesale government bond market operating within Treasury BondSpot Poland. Each index incorporates changes in the prices of bonds included in its portfolio, accrued interest, and income generated through the reinvestment of coupon payments, making it a total return index.

The GPWB-B3Y portfolio consists of Polish złoty-denominated fixed-rate government bonds and zero-coupon government bonds with a remaining maturity of more than three years. The index is designed to provide transparent exposure to the medium- and long-term segment of the domestic government bond market.
