Foreign Treasury Holdings Fall as Yields Hit 2007 Highs

Foreign holdings of US Treasuries declined in June as the benchmark 30-year yield surged to its highest level since 2007, with ING warning the bearish tone has further room to run. The headline foreign holdings figure fell to $9.299 trillion from $9.371 trillion in May, led by reductions from Japan, the UK, and China. Meanwhile, the yield on the 30-year Treasury bond reached 5.321% as of 02:05 UTC today, its highest point since the middle of 2007, reflecting ongoing pressure in the long end of the curve. ING analysts announced on 18 August 2026 that structural factors including geopolitical tensions and increased credit issuance argue for continued upside pressure on yields.

Context — why foreign Treasury selling matters now

Foreign demand for US government debt is a critical pillar supporting federal borrowing. The last time China's holdings fell to current levels was in September 2008, during the global financial crisis. Today's macroeconomic backdrop features substantially higher real yields, which ING characterizes as a normalization toward pre-crisis norms rather than a dislocation. The immediate catalyst for renewed selling pressure is the lapse of a 60-day truce between the US and Iran without resolution. Previous yield spikes above 4.65% on the 10-year note typically elicited calming rhetoric from the Trump administration regarding diplomatic progress with Iran, which has been notably absent this time. This absence removes a psychological support mechanism that previously capped energy price spikes and Treasury volatility.

Data — what the Treasury flow numbers show

Five concrete data points illustrate the June shift in foreign Treasury activity. Total foreign holdings decreased by $72 billion to $9.299 trillion. Japan remained the largest non-US holder despite reducing its position by 2.3% to $1.116 trillion, well below its November 2021 peak of $1.325 trillion. The United Kingdom, often viewed as a proxy for hedge fund activity due to its custody hub status, trimmed holdings by 1% to $939.9 billion. China's holdings dropped 4% to $633.4 billion, marking their lowest level since September 2008 and representing a 13% year-over-year decline. Transaction data presents a conflicting picture, with one measure showing a modest $6.8 billion net inflow while ING's TIC-based calculation indicates a $72 billion net liquidation by foreign holders in June.

Overall net capital inflows into the United States remained strong at $133.5 billion in June, virtually unchanged from May's $131.5 billion. This stability was supported by substantial inflows into risk assets, with equities drawing $181.4 billion and corporate bonds attracting $35.6 billion. The disparity between strong overall capital inflows and specific Treasury outflows suggests rotation within dollar-denominated assets rather than broad dollar divestment. The three-month trend shows net foreign selling of $56 billion against twelve-month net buying of $205 billion, indicating the June move may represent a tactical shift rather than a strategic departure.

Analysis — what it means for markets and sectors

ING's analysis suggests the Treasury selloff reflects structural normalization rather than temporary dislocation. Real yields adjusting toward pre-financial-crisis levels represent a return to historical norms after years of suppression through unconventional monetary policy. The bank identifies two additional pressure points: sustained credit issuance from hyperscaler technology companies and the absence of diplomatic reassurance regarding Iran. These factors create marginal but persistent upward pressure on both yields and energy prices. Credit spreads remain relatively contained despite the yield move, suggesting the repricing reflects rate expectations rather than credit deterioration.

The eurozone banking system shows parallel tightening dynamics. Excess reserves have declined by approximately €300 billion this year to €2.16 trillion, pushing the overnight ESTR rate to its widest spread versus the ECB deposit rate since early 2021. This gradual liquidity reduction contrasts with more abrupt historical tightening episodes. Banks currently maintain reserve buffers well above minimum requirements and show reluctance to utilize ECB facilities due to perceived stigma. ING anticipates this dynamic will eventually force banks to increase use of ECB operations, tentatively projecting early 2027 as the inflection point. This gradual tightening supports structural cheapening views for Bund spreads over the medium term.

Outlook — what to watch next in Treasury markets

Traders should monitor two specific catalysts for Treasury direction. The next US-Iran diplomatic developments will test whether the administration resumes its pattern of yield-curve calming rhetoric when the 10-year approaches 4.65%. The timing of major hyperscaler credit issuance announcements will indicate whether private supply continues to pressure Treasury term premia. Key technical levels include the 5.321% area on the 30-year yield, which represents the 2007 high, and the 4.65% threshold on the 10-year note that previously triggered administrative response.

In European markets, the ESTR-deposit spread warrants monitoring for signs of accelerated liquidity tightening. A sustained move beyond current widest levels since early 2021 would signal mounting pressure on bank funding costs. The ECB's weekly liquidity operation usage, currently at €16.5 billion down from €22 billion in early August, provides a gauge of banking system stress. A material increase above typical 2026 allocations would indicate the transition to tighter conditions is accelerating ahead of ING's early 2027 projection.

Frequently Asked Questions

What does falling foreign Treasury holdings mean for the US dollar?

The impact on the US dollar remains limited because overall capital inflows held steady at $133.5 billion in June. While foreign investors reduced Treasury exposure by $72 billion according to ING's measure, they allocated $181.4 billion to US equities and $35.6 billion to corporate bonds. This rotation within dollar assets rather than away from them suggests the dollar's reserve currency status remains intact. The diversification into higher-risk assets within the US market may actually reflect confidence in American economic growth relative to other developed markets.

How do current Treasury yields compare to historical averages?

The 30-year yield at 5.321% exceeds any level seen since 2007, but ING emphasizes that real yields (adjusted for inflation) are normalizing toward pre-financial-crisis norms rather than reaching unprecedented territory. Before the 2008 crisis, real yields routinely traded higher than during the subsequent decade of quantitative easing and financial repression. The current move represents a return to historical patterns where government debt offered positive real returns, which ING characterizes as healthy normalization rather than dislocation.

What is the significance of China reducing Treasury holdings?

China's 4% reduction to $633.4 billion represents the lowest holding level since September 2008 and a 13% year-over-year decline. While geopolitically significant, the practical market impact is mitigated by China's diminished role as a Treasury buyer over the past decade. China's holdings peaked at $1.325 trillion in November 2021 and have trended lower since. Other buyers including Belgium, Canada, and Switzerland have partially filled the gap, with these nations appearing as net buyers in June according to TIC data.

Bottom Line

Structural normalization of real yields combined with geopolitical tension and credit supply creates persistent upward pressure on Treasury yields.
