With prospects of further interest rate cuts on the anvil, investors seem to be shunning bonds in favor of equities and commodities, according to experts.
Adding more credibility to the view has been the nearly 70-percent rise in the A-share market since the beginning of the year and the anticipation of an ensuing inflation activated commodities trading.
On the supply side, China plans to issue around 1.7 trillion yuan ($248.88 billion) treasury bonds for the whole year. Bonds worth 652 billion yuan have been issued in the first half, leaving some 1.1 trillion yuan worth of bonds to be sold in the second half.
"The supply is huge, but demand is obviously very sluggish," Xu Jin, analyst, Shanghai Securities said.

"With bank interest rates likely to go up in the near future, the allure for treasury bonds may fade," Zhu said.
Investors are growing wary of Chinese debt as the nation's economy is growing faster than expectations. China's gross domestic product grew 7.9 percent in the second quarter, beating the median estimate of 7.8 percent in a Bloomberg survey of eight economists.
