5.42%: 20-Year Treasury Yield Jumps As Foreign Demand Hits A Low

Indirect bidders, the foreign-buyer proxy, took just 52.1% of the reopening, down from the 62-80% range seen earlier in 2026.
- 5.42%: the high yield on the reopened 20-year bond, CUSIP 912810UX4, September 15.
- 5.204%: the yield one month earlier, at the prior reopening of the same bond.
- 52.1%: the indirect-bidder share, foreign proxy demand, versus 62-80% in other 2026 sales.
Why it matters: When the usual foreign buyer will not take the debt, the government simply pays more to whoever will.
