Core conclusion · Tlines extraction

Foreign investors held about $9.2 trillion of US Treasury debt at end-2025, roughly 31% of publicly held debt, but foreign holdings have grown more slowly than total Treasury supply. Within foreign holdings, private investors now account for 58.1% versus 41.9% for official institutions, and the official share of foreign Treasury holdings fell from 59% in 2020 to 43% in 2025. State Street argues de-dollarization headlines are less relevant than this buyer-mix shift, which implies a more price-sensitive investor base, potentially higher term premium, greater volatility and a Treasury market that may need to offer more yield to absorb rising supply.

Key arguments

  • De-dollarization headlines are less relevant than the changing composition of Treasury demand; gradual reserve diversification matters more than any near-term loss of dollar dominance.
  • Foreign holdings have grown in dollar terms but not kept pace with Treasury supply, so other buyers must step in to balance the market.
  • Private investors, now 58.1% of foreign holdings, are more price-sensitive than official reserve managers, so Treasuries increasingly compete for capital and may require higher yields to absorb supply.
  • A more price-sensitive buyer base may raise term premium and volatility, with implications for duration, credit, mortgage and refinancing costs.

Main risks

  • The key risk is not a sudden end of dollar dominance or disappearing Treasury buyers, but a market increasingly reliant on price-sensitive investors to absorb growing debt supply.
  • A higher term premium and greater volatility could raise refinancing costs, alter mortgage prepayment behavior and increase mark-to-market swings, especially for longer-duration securities.
  • Fiscal conditions, auction dynamics and uncertainty around inflation and Fed policy could amplify yield moves as the buyer base changes.
