Global investment managers have been quietly shifting money into Chinese government bonds since the Iran war began, and not because of the returns they offer — but because of how little those bonds move in sync with markets in the West.
While sovereign debt in the United States, Britain, Europe, and Japan has taken a beating since March — with benchmark yields climbing between 35 and 60 basis points — yields on comparable Chinese government bonds have actually dropped by 8 basis points. That’s a dramatic contrast that has turned heads among serious institutional investors.
Sovereign wealth funds, central banks, and insurance companies are all taking a second look at how they build their portfolios, as Chinese bond yields have fallen to the lowest levels anywhere outside of Switzerland.
Wei Li, head of multi-asset investments at BNP Paribas Securities, said Chinese debt is pulling in investors focused on protecting capital. “Attractiveness is judged on a risk-adjusted footing. China delivers exceptional price stability,” Li said, describing the bonds as a low-volatility counterweight for regional portfolios holding riskier, higher-yielding assets.
Chinese bonds have stood out even more given that traditional safe havens have stumbled. Gold, for instance, has fallen roughly 25% from its peak in January.
Even with the Iran conflict appearing closer to resolution — after the U.S. and Iran struck a deal to end fighting and reopen the Strait of Hormuz — many of the factors supporting China’s bond market remain in place. Those include persistently low inflation, a central bank leaning toward looser policy, and heavy domestic investment flows.
Performance numbers tell the story clearly. The Guotai 10-Year China Treasury ETF has gained 1.26% so far this year. By comparison, the U.S.-focused iShares 7-10 Year Treasury Bond ETF has fallen 2.57%, and Invesco’s equivalent Euro bond ETF has slipped 1.23%.
Matthias Dettwiler, head of active fixed income at UBS Asset Management, pointed to the statistical independence of Chinese bonds from European rates. “If you look at correlations between CGBs and European rates, it’s close to zero. That has its attractiveness,” he said. For investors focused on protecting capital or spreading risk, “I would even go as far as to say the absolute yield doesn’t matter so much,” Dettwiler added.
Several structural factors are shielding China’s bond market from the turbulence triggered by the Middle East oil shock. The country holds substantial energy reserves, and consumer spending remains sluggish enough to keep price pressures minimal. On top of that, a large pool of household savings is being funneled by banks into the bond market, keeping yields in check.
Jerome Tay, senior investment manager of fixed income at Aberdeen in Singapore, noted that “liquidity plays a big part in driving the CGB markets, and liquidity conditions have remained extremely abundant.”
Chinese 10-year bond yields currently sit at 1.75%, now roughly one percentage point below Japan’s — a reversal from the dynamic that existed until late 2025, when Japan held the title of the world’s lowest-rate market.
Unlike Japan, however, where years of aggressive central bank stimulus drove capital to seek returns overseas, China’s strict controls on money leaving the country are keeping domestic investment at home.
Stephen Chang, a portfolio manager for Asia at PIMCO, said the contrast between China and other major economies helps explain the stability. “This divergence in macro conditions and policy stance helps explain why China’s bond market has remained relatively stable within a more volatile global rates environment,” Chang said. “We continue to maintain overall exposure to China bonds, focusing on relative value opportunities.”
