Today’s Numbers
5.3% (US 10-year Treasury yield) · 1.70% (China 10-year government bond yield) · ¥358bn (offshore “dim sum” bond issuance, H1 2026). A gap of about 360 basis points between Washington’s and Beijing’s borrowing costs is pulling the world’s borrowers toward the yuan.
On Monday, the US 10-year Treasury yield pushed to a fresh high not seen since 2002, around 5.3%, and the dollar index climbed to its strongest level since April 2025. Mainland China saw none of it: onshore markets are shut for Golden Week until Thursday. The offshore yuan drifted only to about 6.71 per dollar, still roughly 6% stronger than a year ago. That calm hides Beijing’s best opening for financial statecraft in years. As Washington’s borrowing costs climb, China’s benchmark 10-year yield sits at 1.70%.

Start with the spread. Any government, company or development lender choosing a currency to borrow in faces a simple sum: dollars cost more than 5% at the risk-free end, yuan less than 2%. That gap is fuelling a borrowing rush. Foreign issuers sold ¥160bn of panda bonds, which are yuan debt issued inside China, in the first half of 2026. They also sold ¥358bn of offshore dim sum bonds. Both are up more than 60% on a year earlier, Goldman Sachs figures show.
The first winners are borrowers with a yuan option. Kenya converted its Standard Gauge Railway debt from dollars into yuan last October and put the saving at about $215mn a year. Pakistan’s 2025 refinancing with China Development Bank, Bank of China and ICBC was rolled over in renminbi rather than dollars, and Ethiopia has sought the same treatment. Each conversion lets China’s state lenders lend their own currency instead of dollars they must find abroad.
The second winner is the People’s Bank of China. Official reserves reached $3.4383tn at the end of August, the highest since 2015. That month it added 20 tonnes of gold, the largest purchase of its 22-month buying streak. China’s directly held US Treasuries fell to $618bn in July, the lowest since 2008, just as Washington needs more buyers.
The losers are dollar-indebted emerging-market governments without a Chinese lifeline, and the US Treasury itself, which is replacing patient central-bank buyers with price-sensitive private money.
There is a catch for borrowers. The yuan’s 6% rise against the dollar over the past year eats into the interest saving for anyone whose income is in dollars. That is why the PBOC’s habit, since November 2025, of setting its daily fix weaker than market forecasts matters beyond trade. By capping appreciation, Beijing also protects the new yuan debtors it is courting.
Why It Matters
The currency of a debt is a currency of dependence. A government that owes dollars ultimately answers to the Fed’s rate path and, in a crisis, to the IMF and the US Treasury. A government that owes yuan must either earn yuan, through exports to China, or borrow it, through one of the PBOC’s bilateral swap lines. Each conversion moves a slice of a debtor’s financial vulnerability from Washington to Beijing.
The irony is that Washington is financing the shift. The same fiscal and inflation worries pushing US yields to 24-year highs are what make Beijing’s money look cheap by comparison. China’s low yields are not a sign of strength. They reflect weak domestic demand and investors’ disappointment with the latest stimulus. But in foreign policy, cheap money spends regardless of why it is cheap.
The limits are real. The yuan still accounts for only about 3% of global payments, capital controls keep China’s onshore markets half-closed, and borrowers know Beijing’s terms come with political strings. Goldman’s warning fits: a boom built on low rates rather than trust may not last. Cheap funding wins a debt deal; it does not by itself win a reserve currency. But for finance ministries from Nairobi to Islamabad facing dollar costs above 5%, the choice is no longer theoretical.
Watch For
Wednesday, 7 October: the State Administration of Foreign Exchange publishes September reserve data, including the PBOC’s gold holdings. A 23rd straight month of gold buying, with gold above $4,100 an ounce, would confirm that Beijing is using its dollar inflows to move away from US debt, not to rebuild its Treasury holdings. A pause would suggest that the strong dollar and high gold prices are finally testing that strategy.
