China's 5-Year Government Bond Yield Hits Record Low as PBOC's Single-Day Net Injection Sets New High
nashnova research
China's 5-year government bond yield briefly touched 1.34%, the lowest close on ChinaBond data back to 2002, after the PBOC injected a record net 1.01 trillion yuan (~$151 billion) via reverse repos in a single day.
What happened?
During the session on the 27th, China's 5-year government bond yield briefly hit 1.34% — the lowest closing level in ChinaBond records dating to 2002.
The same day, the People's Bank of China injected a net 1.01 trillion yuan (~$151 billion) through open-market reverse repos — short-term loans to banks that are repaid within days — the largest single-day net injection in Bloomberg's records.
This means → the PBOC flooded the banking system with over a trillion yuan in one session, pushing borrowing costs sharply lower.
Why did the yield fall to a record low?
The massive net injection left the interbank market flush with cash, pulling down short- and medium-term funding costs simultaneously.
The 5-year bond is a benchmark for medium-term rates. When banks get cheap funding, they buy government bonds to lock in returns — that buying pushes bond prices up and yields down.
In plain terms = more money chasing bonds means higher prices and lower yields — that is how the yield hit its all-time low.
What does this signal for the market?
A record-low yield shows the market has priced in even deeper PBOC easing, betting that policy will stay accommodative.
This reflects a bullish mood in the bond market that is likely to persist in the near term — as long as the PBOC keeps injecting at high intensity, yields will struggle to rebound significantly.
One caveat: single-day mega-injections often coincide with month-end or quarter-end liquidity gaps, so whether this pace continues remains to be seen.
