SHANGHAI - Prices of three of China Central Depository & Clearing's (CCDC) domestic green bond indices were simultaneously displayed in the Luxembourg bourse starting Wednesday.

The bonds indices, including ChinaBond China Climate-Aligned Bond Index, ChinaBond China Green Bond Select Index, and ChinaBond China Green Bond Index, are designed to reflect the performance of Chinese domestic green bonds mainly used to support projects in China, including clean transportation and green finance.

With their simultaneous display on the Luxembourg Stock Exchange (LuxSE), overseas investors can get a better understanding of the China bond market.

"Today marks a milestone in the development of the links between China's domestic green bond market and the international investment community," said Robert Scharfe, CEO of Luxembourg Stock Exchange.

Scharfe said the display of these indices in China and on the LuxSE platform closes an existing information gap on Chinese green bonds for investors around the globe, which marks the first step of an even more substantial cooperation on the basis of the vast portfolio of existing green bonds currently present in the portfolio of CCDC bonds.

Jin Penghui, deputy director of the People's Bank of China (PBC) Shanghai Head Office and director of PBC Shanghai Branch, said the overall volume of China's bond market exceeded 81 trillion yuan ($11.8 trillion) at the end of this August, ranking third in the world, and the volume of China's green bonds reached 495.3 billion yuan.

By the end of this August, 1,147 overseas investing institutes held 1.75 trillion yuan of China's bonds, accounting for 2.4 percent of the market. The scale of bonds held by overseas investors has seen continuous growth over the past 18 months.
