On Friday alone, more than a dozen bond funds announced measures to restrict new purchases, according to fund managers' filings. Around 40 short-term bond funds made similar statements in the past 20 trading days, according to Chinese newspaper China Fund.
Xia Haojie, bond analyst at Guosen Futures, said bond funds looked increasingly attractive for investors at a time when banks are lowering their deposit rates.
China's top five state lenders cut individual deposit rates last week, a move that could help bring down lending rates further to aid the economy. The rate cuts came on top of reductions in certain deposit rates in April.
A bond fund manager, who declined to be named, also attributed the flight to bonds to a bearish stock market, and a tendency to seek shelter ahead of the week-long Chinese National Day holiday that starts Oct 1.
China's blue-chip index CSI300 has tumbled more than 20% so far this year amid gloomy economic prospects.

China may need to cut banks' required reserve ratio (RRR) in the fourth quarter to keep liquidity ample, the official China Securities Journal reported on Saturday, citing economists. Easier monetary conditions could push bond prices higher.
