US Treasury to buy back 10- and 20-year bonds worth $6 billion
The US Treasury announced on Wednesday, September 9, that it plans to buy back 10-year and 20-year US government bonds worth $6 billion to boost liquidity and support government bond prices under pressure from rising bond yields. This buyback amount is three times the normal buyback level and higher than what US Treasury Secretary Scott Bessent said in August, when he indicated the buyback of older bond issues would be increased by at least two times, or about $4 billion. However, the market had expected the buyback to be between $6 billion and $10 billion, making the announced $6 billion the lower bound of expectations. As a result, the market reacted negatively and long-term bonds saw selling pressure, with the 10-year bond yield reaching 4.841%, while the 20-year bond yield rose to 5.314%, and the 30-year yield jumped 5 basis points, breaking above 5.3%. The buyback will be conducted on Thursday, lasting 20 minutes and ending at 2:00 p.m. US Eastern Time. The rise in US bond yields stems from multiple factors, including rapidly increasing government debt that just surpassed $40 trillion, inflation concerns from import tariff measures, the Iran war, and crude oil prices breaking above $100 per barrel on Wednesday.
US Treasury Buys Back Long-Dated Bonds Worth Up to $6 Billion, Tripling Its Usual Pace
The US Treasury announced it will buy back up to 6 billion dollars in long-dated government bonds, three times the normal level of 2 billion dollars, amid pressure from surging bond yields and rising government debt. The actual buyback will take place on Thursday, running for 20 minutes and ending at 2:00 p.m. Eastern Time. The Treasury said future operations will be at least 4 billion dollars. The move follows Treasury Secretary Scott Bessent's statement on August 19 that he would increase buybacks of already-issued securities by at least double the normal level. Although the measure aims to keep liquidity stable in the 10-year and 20-year bond markets, the market reacted negatively: the 10-year bond reached 4.841%, the 20-year rose to 5.314%, and the 30-year broke through the 5.3% level that the market sees as key, most recently yielding 5.307%. US government bond issuance this year is up 11.8% from 2025, while publicly held debt of 31.8 trillion dollars has risen 8.2%.

US Treasury Expands Bond Buyback Cap to 92 Billion Yen
The US Treasury announced on the 9th that it will expand the maximum buyback amount for long-term bonds to $6 billion (approximately 92 billion yen). The bonds targeted are those with maturities of 10 to 20 years, and the first buyback will be conducted on the 10th. The Treasury had indicated a plan to increase the per-operation cap to $4 billion, more than double the current level, but by adding further to the initial plan, it aims to curb interest rates that have been on an upward trend without stopping. However, in the financial markets on the 9th, the yield on 10-year Treasuries temporarily reached the 4.85% range, the highest level in about 2 years and 10 months since November 2023. The yield on 20-year bonds also surged. With views spreading that the buyback scale is insufficient, bond selling progressed due to disappointment.
Treasury Doubles Long-Dated Bond Purchases, Complicating Fed Policy
The U.S. Treasury Department announced on August 19 that it will double its purchases of long-dated Treasury bonds from $2 billion to $4 billion, a surprise intervention that complicates the Federal Reserve's inflation fight. Treasury Secretary Scott Bessent's move aims to push down yields on 10-, 20-, and 30-year bonds, which have surged to near multidecade highs amid above-average inflation, the removal of forward guidance by Fed Chair Kevin Warsh, and U.S. debt crossing $40 trillion for the first time. The intervention could lower corporate borrowing costs and mortgage rates, but it may force Warsh and the FOMC to raise the federal funds target rate to maintain price stability, especially as core PCE inflation shows the Iran war's price pressures have become entrenched. Warsh, sworn in on May 22, faces a dilemma: act against sticky inflation and risk angering President Donald Trump and halting the AI-driven stock rally, or do nothing and let inflation accelerate.

US Treasury doubles debt buyback to steady bond market
The US Treasury is doubling its buyback of government debt to steady the bond market amid investor concern over high inflation. Yields on 10-year, 20-year and 30-year Treasury notes hit 20-year highs this week, with the 30-year yield reaching its highest since 2007, before dropping after Wednesday's announcement. The Treasury said the move reflects its desire to provide greater liquidity support to the long-term bond market. The action follows the Trump administration's intervention to prop up the yen in partnership with Japan, a large holder of US Treasuries. Annualized US inflation was 3.4% in July, down from 4.2% in May but nearly 1% higher than 2025 rates, while gas prices are on track for the highest August on record at $4.08 a gallon.

US 20-year Treasury auction tests investor appetite amid global bond rout
The U.S. Treasury will auction $16 billion of 20-year bonds on Wednesday, with investors expected to demand a yield near 5.28%, the highest since the tenor was introduced six years ago. The auction comes as the U.S. budget deficit has reached nearly $1.8 trillion this fiscal year and the national debt is expected to soon breach $40 trillion. Last week's 30-year auction yielded 5.216%, the highest in a quarter-century, while the 30-year Treasury yield briefly hit 5.327% on Tuesday, its highest since June 2007. The Treasury announced it will at least double debt buybacks targeting 10- to 30-year maturities, which helped ease yields on Wednesday. Analysts cited fiscal deficit concerns as the dominant driver of the long-end selloff, with global yields also rising due to deficits and higher energy prices from the Iran conflict.
