China's Central Bank Plans to Include Long-Term Bond Holdings in Macroprudential Assessment
nashnova research
The PBOC plans to add new metrics to its MPA framework to curb banks' excessive long-bond and fund holdings; some smaller lenders may face portfolio rebalancing pressure, potentially capping the rally that has driven Chinese bond yields to multi-month lows.
What exactly is the PBOC planning?
According to Reuters, citing people familiar with the matter, the PBOC will introduce new metrics into its Macro-Prudential Assessment (MPA) — a scoring framework that rates how prudently banks operate.
The metrics target two things: the size of banks' long-dated bond and related fund holdings, and how far those positions deviate from money-market and bond-yield benchmarks.
This means → the PBOC will judge not just how much banks have bought, but whether the prices they paid have drifted from reasonable market levels.
Specific benchmark parameters are still under discussion with the industry and have not been finalized; the PBOC declined to comment.
Why act now?
China's bond market has rallied steadily this year, diverging sharply from the global bond sell-off.
As of Monday, the 10-year government bond yield stood at 1.68%, hovering near its lowest since July 2025; the 30-year yield was at 2.17%.
In plain terms = lower yields mean higher prices — banks have been buying aggressively enough to push prices to extreme levels.
This reflects how weak economic data has reinforced expectations of further easing, drawing capital into bonds as a haven.
Who faces the biggest impact?
Market participants note that some small and mid-sized banks may hold bond durations and fund positions that exceed the coming limits.
This means → those banks could be forced to rebalance their portfolios — selling long-dated bonds and shortening duration.
In plain terms = duration — a measure of how sensitive a bond is to interest-rate swings — amplifies losses when rates bounce. The PBOC's concern is precisely this risk concentrating in smaller lenders.
What is MPA, and why does it matter here?
The MPA framework was launched by the PBOC in 2016 as a core pillar of China's "twin-pillar" regulatory system.
In plain terms = one pillar — monetary policy — manages rates and liquidity; the other — MPA — monitors whether banks' business conduct is sound. Two legs, one body.
Folding long-bond holdings into MPA elevates bond-market risk to the same regulatory tier as credit risk.
What to watch next?
Whether the new rules can effectively curb banks' appetite for long-duration bonds is the key question going forward.
The final calibration of benchmark parameters will determine policy bite — set the threshold loosely and the effect is limited; set it tightly and smaller banks face an abrupt rebalancing squeeze.
This means → the bond market may see short-term volatility on tightening expectations, but the longer-term trajectory still depends on economic fundamentals and the pace of easing.
