Recent trends reveal a significant shift in how foreign investors approach US Treasury bonds, traditionally viewed as a stable financial refuge during periods of global uncertainty. This change in investor sentiment might hint at upcoming instability in the Treasury bond market, prompting market analysts and participants to closely monitor developments.
A financial strategist from Tandexo delves deeper into this evolving landscape, clarifying what reduced foreign demand could imply for US economic stability.
Notable Drop in Treasury Demand
According to recent insights from Bank of America, there’s a clear sign of declining foreign appetite for US Treasury bonds, raising concerns about potential volatility in the bond market. In a report titled “Foreign UST Demand Shows Cracks,” the bank highlighted the unusual scenario of foreign buyers, including central banks, significantly reducing their Treasury purchases.
A senior rates strategist from Bank of America noted that holdings of US dollar assets have decreased by more than $60 billion since early April. The most recent 20-year Treasury bond auction saw particularly low foreign participation, the weakest since July 2020.
Custodial holdings, referring to US Treasury securities held by foreign central banks at the Federal Reserve, have fallen notably, down $17 billion last week alone and totaling a $48 billion decline since March.
Why Reverse Repos Matter

Another indicator, the Federal Reserve’s use of reverse repurchase agreements (reverse repos), has also signaled this diminishing interest. Reverse repos allow institutions to temporarily lend cash to the Fed overnight, securing the loan with high-quality short-term Treasury bonds as collateral.
Since late March, reverse repo balances have shrunk by approximately $15 billion, hinting at lower Treasury demand among global central banks.
These signs collectively underline a shift from earlier in 2025, when Treasury demand was significantly driven by broker-dealers and foreign investors. Now, this trend appears to be reversing, posing questions about future demand sustainability.
Atypical Behavior Amid Weak Dollar
What makes the current trend particularly unusual is that foreign demand typically rises during periods when the US dollar weakens, as Treasury bonds become cheaper and more attractive to international investors. This year, the US dollar index has fallen by over 9%, yet foreign central banks are not capitalizing on this opportunity as they historically have.
Previously, persistently low interest rates around the globe drove international investors toward US Treasurys for better returns. Foreign investors have accumulated historically high holdings of long-term US government bonds, especially those with maturities over 10 years. Consequently, any adjustment to these holdings could disproportionately impact market stability.
Concerns About US Fiscal Health and Tariffs
Why the sudden shift away from Treasurys? Market observers point to increasing concerns about America’s fiscal trajectory, particularly its growing deficit, and broader economic anxieties linked to trade tensions.
Uncertainties driven by tariffs and recent fiscal policies from America’s current administration are prompting foreign investors to diversify away from US assets, thus reducing Treasury bonds’ perceived safety and appeal.
These concerns about America’s fiscal condition and its economic outlook, compounded by ongoing trade disruptions, make foreign investors hesitant to maintain or increase their exposure to US debt. Analysts note that foreign investors, traditionally key players in the Treasury market, scaling back their purchases could lead to higher market volatility and possibly higher yields if this trend persists.
Implications for Market Stability
Reduced foreign involvement in the Treasury market raises questions about who will absorb upcoming bond issuances needed to finance the US government’s deficit spending. A persistent drop in foreign demand could force the Treasury to offer higher yields to attract other investors, thus raising borrowing costs and impacting the broader economy negatively.
Additionally, if foreign central banks continue reducing their Treasury holdings or raising hedge ratios, this might amplify currency volatility and further destabilize financial markets. Investors must now closely watch these trends, as they will influence future interest rate decisions, currency valuations, and broader market dynamics.
Conclusion: Preparing for Potential Volatility
While the Treasury market remains one of the world’s largest and most liquid, shifts in foreign investor behavior could introduce unexpected turbulence. Analysts agree that the current reduction in foreign demand is noteworthy and potentially worrying if prolonged.
For market participants, closely tracking central banks’ actions and global investor sentiment is now crucial. This change in foreign demand underscores broader concerns about America’s fiscal policies and global economic conditions. A financial expert from Tandexo suggests that continued vigilance is necessary, as any further signs of weakness in Treasury demand could signal significant upcoming market adjustments.
