Wide US-China bond yield gap not expected to spark capital exodus, says Marsh
The yield gap between 10-year US Treasury and Chinese government bonds reached a record 3.17 percentage points. Marsh Investment executives argue this is due to US fiscal pressures and global trends, not a structural decline in Chinese assets. They do not expect the gap to cause significant capital flight from China.
The unprecedented 3.17 percentage point gap arose as US 10-year Treasury yields climbed to 4.85%, a peak since 2023, while China's equivalent remained steady at 1.68%. Marsh executives attribute the US yield surge to fiscal pressures, expanding national debt, and heavy corporate borrowing in technology and AI sectors, rather than a fundamental deterioration in Chinese assets.
Regarding global currency dynamics, O'Sullivan emphasized that replacing the dollar as a reserve currency requires massive systemic infrastructure. To manage elevated US financing costs, borrowers are diversifying funding and turning to offshore yuan bonds, which supports the view that dollar dominance remains intact despite the wide yield differential.
The persistent yield gap could influence global investment flows, potentially prompting some investors to shift portfolios toward US assets, which may exert mild downward pressure on the yuan. However, if capital flight remains limited, Chinese policymakers could maintain stable domestic liquidity. For international borrowers, the gap might accelerate diversification into offshore yuan instruments, gradually reshaping regional financing patterns. Ultimately, the impact on ordinary savers and businesses depends on whether US fiscal trends stabilize or continue to widen the differential.
