China's low CGB yields defy the global bond selloff, sharpening the diversification case

The Quick Take

• Chinese government bond yields have stayed anchored at multi-year lows even as US, UK, Japan and euro-area yields march higher on sticky-inflation fears.
• The divergence hands global allocators a rare uncorrelated duration book, boosting CGBs' appeal as a portfolio diversifier.
• PBOC's ample-liquidity stance and weak domestic-demand backdrop are what keep the CGB curve pinned while others sell off.

The Chinese government bond curve is the standout outlier in a synchronised global long-end selloff. While 10-year Treasuries, gilts, Bunds and JGBs have all repriced 25 to 60 basis points higher over recent weeks on sticky-services CPI and fiscal-borrowing concerns, CGBs have held at multi-year yield lows. The underlying drivers are structural: soft private consumption, an unresolved property drag, and a PBOC keeping ample-liquidity conditions through open-market operations and RRR calibration. This makes CGBs behave like the anti-Treasury for global macro books — a diversifier when everything else is selling.

The market implication is that global-bond aggregate benchmarks that included CGBs (FTSE WGBI, Bloomberg Global Agg) have been supported by the China leg even while their US, Europe and Japan sleeves lost ground. Foreign holdings of CGBs, tracked via CIBM and Bond Connect data, have been rising — CIBM inflows persist despite the yuan drifting weaker. That in turn steepens the DXY vs CNH-hedged carry math for USD-based investors and gives PBOC room to hold policy accommodative without triggering imported inflation the way emerging peers must worry about.

Forward, watch weekly Bond Connect flow updates and monthly CIBM foreign-holdings statistics for confirmation the diversification bid is durable rather than tactical. The August LPR fixing and any RRR move signal PBOC's next liquidity marker; a surprise stimulus package could actually push CGB yields higher on growth optimism, which is the risk to the anti-Treasury thesis. The macro variable is the yuan: a defended CNH cap by PBOC keeps the diversifier thesis intact, but a policy shift to let CNH weaken faster would force foreign holders to accept currency risk that erodes the yield-differential trade.
