China’s holdings of U.S. Treasury securities fell to $590.7 billion in August, the lowest level since August 2008 and the first reading below $600 billion in 18 years. The figure comes from the Treasury Department’s Treasury International Capital report released October 16, which showed Beijing shedding $27.3 billion of Treasury debt in a single month and $109.0 billion over the past year. Japan stayed the largest foreign creditor at $1,068.3 billion but cut its own position by $35.6 billion, while the United Kingdom added $11.2 billion to close above $1 trillion for the first time at $1,009.5 billion. Total foreign holdings still rose, reaching $9,331.7 billion from $9,248.4 billion in July, because private buyers in Europe and the Caribbean more than replaced what official institutions sold. That split is the part worth watching. Foreign official accounts, meaning central banks and sovereign funds, trimmed holdings for a second straight month to $3,755.6 billion, down $164.2 billion from a year earlier. Those are the buyers Treasury counts on to absorb a rising auction calendar, and the yields they set feed into the mortgage and auto loan rates households pay. The 7.00% prime rate behind credit card and HELOC pricing still answers to the Federal Reserve, which next meets October 28. The composition of the national debt ownership base answers to the auction calendar.
- China held $590.7 billion of Treasury debt in August, the lowest total since August 2008.
- Beijing cut $27.3 billion in one month and $109.0 billion over 12 months, a 15.6% decline.
- The United Kingdom topped $1 trillion for the first time, at $1,009.5 billion, within $58.8 billion of Japan.
- Total foreign holdings rose to $9,331.7 billion, but official accounts fell to $3,755.6 billion.
- The 10-year Treasury note closed at 5.10% on October 15, with prime at 7.00%.
What Changed: Below $600 Billion for the First Time Since 2008
Treasury publishes country-level holdings of U.S. government securities each month with a six-week lag, and the August 2026 table put China, Mainland at $590.7 billion. July stood at $618.0 billion and June at $633.4 billion, so the position has dropped in each of the last three reported months. Treasury’s historical series shows the last reading under $600 billion was August 2008, when China held $573.7 billion on the way up. By September 2008 the figure had already passed $618 billion, and it did not return to this territory for 18 years. The decline from the November 2013 peak of $1,316.7 billion now totals $726.0 billion, a 55.1% reduction.
Scale matters when reading the number. China’s $590.7 billion is 6.33% of the $9,331.7 billion foreigners hold in total, down from 7.56% a year earlier. Treasury cautions in the notes to the table that the data come from U.S. custodians and broker-dealers, so securities a government holds through a custodian in London or Brussels can be attributed to that intermediary rather than the beneficial owner. Belgium, home to a large custodial operation, holds $490.5 billion and added $19.8 billion in August. That caveat limits how much any single country line can carry, which is why the official-sector aggregate discussed below is the more reliable gauge of central bank behavior.
Who Bought Instead: Britain Crosses $1 Trillion
The headline total rose even as the two largest holders sold, and the United Kingdom explains most of the gap. British holdings reached $1,009.5 billion in August from $998.3 billion in July, the first time the line has printed above $1 trillion in the TIC record. A year earlier the figure was $901.3 billion, so Britain has added $108.2 billion over 12 months, almost exactly offsetting the $109.0 billion China shed. The United Kingdom now trails Japan by $58.8 billion, the narrowest gap between the top two foreign holders in the series. London functions as a booking center for hedge funds, asset managers and sovereign accounts worldwide, so the British line reflects leveraged private demand far more than it reflects official reserves.
Japan’s position tells a different story. Tokyo held $1,068.3 billion in August, down $35.6 billion in the month and $141.6 billion from the April reading of $1,209.9 billion. Canada added $38.3 billion to $464.6 billion, the Cayman Islands rose to $463.0 billion, and Luxembourg reached $448.2 billion. India added $17.1 billion to $219.7 billion and has rebuilt its position from $181.0 billion in April. The pattern across those lines is consistent: domiciles associated with private asset managers and leveraged funds grew, while the two large reserve managers reduced. That rotation changes the character of the buyer base even when the aggregate looks stable.
The Official Sector Is the Number That Matters
Treasury separates foreign official holdings, the central banks and sovereign wealth funds, from everything else. That line fell to $3,755.6 billion in August from $3,773.1 billion in July and $3,919.8 billion a year earlier, a 12-month decline of $164.2 billion. Official accounts now hold 40.2% of all foreign-owned Treasury debt, down from 42.4% in August 2025. The retreat is concentrated at the short end. Foreign official holdings of Treasury bills dropped to $312.2 billion from $354.4 billion in July and $457.3 billion in April, while official holdings of bonds and notes edged up to $3,443.4 billion. Central banks are letting bills mature without rolling them.
Timing explains why that detail carries weight. Treasury has leaned heavily on bills to fund the deficit, and bills stood at $7.118 trillion on September 30, or 22.4% of the $31.835 trillion in marketable debt. When official buyers step back from the front end, dealers and money market funds have to absorb the supply, and they price it. Recent auctions have cleared at elevated levels: the 30-year bond sold October 8 at a high yield of 5.618% with a bid-to-cover ratio of 2.54, and the 10-year note cleared 5.300% on October 7. Treasury sells $13 billion of 20-year bonds October 21 and $26 billion of 5-year notes October 22, the next direct test of demand.
What Changes for Your Money
Nothing in the TIC report moves a consumer rate directly, and no lender reprices because of a monthly custodial survey. The transmission runs through Treasury yields. Foreign holdings of $9,331.7 billion equal 28.7% of the $32.538 trillion in federal debt held by the public, so the willingness of that group to keep buying helps set the level of the Treasury yield curve. The 10-year note closed at 5.10% on October 15 and the 30-year bond at 5.43%. Fixed mortgage quotes are priced off the 10-year, so sustained official selling tends to show up in current mortgage rates with a lag of weeks rather than days.
Short-term borrowing costs follow a different channel. Credit card APRs, HELOCs and most variable business lines sit at a margin over the 7.00% prime rate, which moves only when the Federal Open Market Committee changes its target range. The Federal Reserve reported the federal funds effective rate at 3.88% on October 15 and the primary credit rate at 4.00%. Deposit pricing tracks short-term Treasury yields instead, and with the average rate on outstanding Treasury bills at 3.870% on September 30 there is limited pressure on banks to cut. Savers comparing high-yield savings accounts and CD rates should watch the October 28 decision rather than this release. Borrowers weighing personal loan offers face fixed quotes set off longer yields.
Treat the TIC report as a signal about the long end, not the short end. If you are deciding between a fixed-rate and a variable-rate loan, the relevant question is whether you expect the 10-year yield to stay near 5.10%. Lock a fixed rate when you need payment certainty for more than three years. Keep a variable balance only if you can retire it before the next repricing. Check the yield, not the headline country figure, before you commit.
Frequently Asked Questions
How much U.S. debt does China hold?
China held $590.7 billion of U.S. Treasury securities in August 2026, according to Treasury’s Treasury International Capital report released October 16. That is the lowest monthly total since August 2008 and down from $618.0 billion in July. China is the third-largest foreign holder, behind Japan at $1,068.3 billion and the United Kingdom at $1,009.5 billion.
Who is selling U.S. Treasury bonds?
Official institutions are the net sellers. Foreign central banks and sovereign funds reduced their combined holdings to $3,755.6 billion in August from $3,919.8 billion a year earlier, a drop of $164.2 billion. Most of that came out of Treasury bills, where official holdings fell to $312.2 billion from $457.3 billion in April. By country, Japan cut $35.6 billion in August and China cut $27.3 billion. Private investors moved the other way, which is why the total foreign holding still rose to $9,331.7 billion.
Who owns most of the U.S. Treasury debt?
Domestic holders own the majority. Federal debt held by the public was $32.538 trillion on October 15, 2026, and foreign investors accounted for $9,331.7 billion of it as of August, roughly 28.7%. The remainder sits with U.S. mutual funds, pension funds, banks, insurers, state and local governments, the Federal Reserve and individual savers. A further $7.850 trillion of total debt is intragovernmental, owed to trust funds such as Social Security rather than to any outside investor.
Who are the largest foreign holders of U.S. bonds?
Japan ranks first at $1,068.3 billion in August 2026, followed by the United Kingdom at $1,009.5 billion and China at $590.7 billion. Belgium holds $490.5 billion, Canada $464.6 billion, the Cayman Islands $463.0 billion and Luxembourg $448.2 billion. Treasury notes that custodial reporting can attribute securities to the country of the custodian rather than the owner, so financial centers such as Belgium, the Cayman Islands and Luxembourg appear larger than their domestic savings would suggest.
Does foreign selling raise my mortgage rate?
Indirectly, and not on the schedule of any single report. Fixed mortgage rates are priced off the 10-year Treasury note, which closed at 5.10% on October 15, 2026. When foreign official buyers reduce their share of each auction, remaining investors generally require a higher yield to absorb the supply, and mortgage quotes follow within weeks. A single month of selling by one country rarely registers. A sustained decline in official demand across quarters does, and it can be offset by softer inflation data.
Does this change my credit card APR or savings rate?
No. Credit card APRs and HELOC rates are set at a margin over the prime rate, which is 7.00% and changes only when the Federal Open Market Committee adjusts its target range. The next scheduled decision is October 28, 2026. Savings and CD yields track short-term Treasury yields, and the average rate on outstanding Treasury bills was 3.870% on September 30. Foreign holdings data affect neither channel on their own, so the Fed meeting is the event to watch.
Watching Foreign Demand Through the October 28 Fed Meeting
Two dates matter next. The 20-year bond auction October 21 and the 5-year note auction October 22 will show whether private demand can keep absorbing supply at current yields, and the October 28 FOMC decision sets the rate at which the bill portion of the debt is refinanced. September TIC data arrive in mid-November. Ongoing figures are tracked on our page on who owns the U.S. debt, the interest on the national debt tracker, and the 2026 Fed meeting schedule.
