A relentless drop in China's long-end yields is driving an aggressive curve flattening, laying bare a stark macro rift with global markets where long-dated rates have hit multi-year peaks.

While major economies grapple with persistent inflation and hawkish central banks, China's monetary easing and property sector woes have pushed investors into sovereign debt. The 30-year government bond yield has fallen below 2.5%, a historic low, even as U.S. Treasuries and European bonds face heavy selling pressure.

This divergence reflects Beijing's prioritization of growth over currency defense. The PBOC's measured stimulus contrasts sharply with the Fed's higher-for-longer stance, creating a rare scenario where Chinese duration outperforms during a global bond rout.

Market participants note the flattening curve signals expectations of prolonged domestic weakness. Foreign holdings of Chinese bonds have stabilized after months of outflows, suggesting international allocators are reassessing the asset class as a hedge against developed-market volatility.
