19.08.2026 - Treasury Rushes to Stabilize Yields
Just one day after long-term US Treasury yields surged to levels not seen in nearly two decades, Washington is stepping in.
The US Treasury Department announced that it will at least double the size of its liquidity-support debt buybacks in the long end of the Treasury market, starting September 9. The measures specifically target the 10–20 year and 20–30 year maturity segments, where pressure has been particularly pronounced.
The maximum size of individual buyback operations will increase from USD 2 billion to at least USD 4 billion.
The objective is clear: improve liquidity and relieve pressure in the long end of the US government bond market.
The market reaction was immediate. Treasury yields dropped sharply, while US equity futures jumped, once again showing how sensitive equity markets have become to developments in the bond market.
Yesterday's move in the 30-year yield to a new 19-year high was another warning signal. Today, Washington responded.
Markets:
Equities: Mixed as the news impact was only short lived
Bonds: yields falling across the globe - US 10y yield above 4.65%, Japan 10y yield 2.90%
Commodities: Oil prices slightly higher, WTI around USD 86/barrel and Brent around USD 91/barrel
Precious metals prices jump higher, gold close to USD 4’460/oz, silver moves towards USD 65/ozCurrencies: US dollar falls, Japanese Yen strengthened, USDJPY 157
Cryptos: higher - Bitcoin above USD 65k
Volatility: The VIX index little changed with level above 15 (still good opportunity for hedging)
My View: Market intervention continues and is a clear sign how dramatic the situation is, less than half a step towards the edge.
The bigger question is: for how long can this work?
Calling today's announcement outright "market manipulation" may be too simplistic, because Treasury buybacks are an established debt-management tool designed to improve market liquidity. But the broader pattern is becoming increasingly difficult to ignore.
Whenever financial conditions become uncomfortable, another measure appears to stabilize markets. The Treasury is now increasing its presence precisely where the pressure has become most visible: the long end of the US government bond market.
This can certainly provide short-term relief. But it does not address the fundamental reasons why long-term yields have been rising.
The US debt burden remains enormous. Fiscal deficits remain elevated. Refinancing costs are increasing. Inflation remains above the Fed's target. And the government continues to require substantial amounts of new financing.
Furthermore, major holders of US Treasuries, such as China and Japan, have increasingly been on the sell side, adding further pressure to an already strained bond market.
Buying back bonds can improve liquidity. It cannot make the underlying debt problem disappear.
The political dimension should also not be underestimated. With the November midterm elections approaching, the Trump administration has a strong incentive to prevent a disorderly rise in yields and a corresponding correction in equity markets.
In my view, the stock market remains one of the administration's strongest economic arguments going into the midterms. Washington therefore has every incentive to keep financial conditions supportive for as long as possible.
The question is what happens when markets begin to demand fundamental solutions rather than additional support measures. For now, investors are celebrating lower yields and higher equity prices.
But today's intervention reinforces my broader view: The bond market is increasingly signaling the key risk for global financial markets, and the growing public debt problem remains one of the most underestimated risks.
