Chinese and American 10-Year Borrowing Costs Diverge to the Widest Gap on Record

The yield on the 10-year United States Treasury note rose to 4.85 percent on Wednesday, its highest since 2023, while the equivalent Chinese government bond held near 1.68 percent. The resulting gap of 3.17 percentage points is the widest in Bloomberg data going back to 2002. The Financial Times reported that the divergence threatens to accelerate a shift in capital flows between the world's two largest economies.

The two yields are moving apart because the two economies face opposite problems. American long-term rates are rising on an oil-driven inflation impulse, heavy Treasury issuance and the prospect of a Federal Reserve increase. Chinese yields sit near multi-decade lows because domestic demand is weak and the People's Bank of China is holding policy loose. A gap this wide gives global investors a strong incentive to hold dollar paper rather than yuan paper, which pressures the Chinese currency and limits how far Beijing can ease without importing capital outflows.

The squeeze shows up immediately in Asian project finance. The Asian Infrastructure Investment Bank is developing a platform to pool money from pension funds, insurers and other institutional investors, aiming to roughly quadruple the private capital it mobilises for infrastructure across the region, against an estimated $1.7 trillion of annual need. Every one of those projects competes against a risk-free dollar yield that has just become materially more attractive.

There is a sound-money reading of the same numbers. For two decades the dollar system exported cheap credit to emerging Asia. That flow now runs in reverse because Washington itself must pay more to borrow, and the discipline is being imposed by bondholders rather than chosen by policymakers.
