September 11, 2026 — The U.S. Treasury market remains under sustained selling pressure, with the 10-year yield approaching 5% and the 30-year yield briefly reaching 5.35%. The move highlights how strongly markets are pricing in a prolonged high-rate environment. Even as the Treasury Department increases its long-dated Treasury buybacks, inflation risks, fiscal deficits and growing demand for long-term capital continue to push yields higher. At the same time, rising oil prices and stronger rate-hike expectations are adding pressure ahead of the CPI release, while the AI infrastructure investment boom is creating another major source of demand for long-term funding.
Treasury Yields Approach 5% Despite Larger Buybacks
The pressure on the U.S. Treasury market has remained intense. On September 11, the 10-year Treasury yield rose to around 4.94%, while the 30-year yield briefly touched 5.35%, underscoring the extent to which markets are pricing in a prolonged period of elevated interest rates.
The Treasury Department has raised the cap on long-dated Treasury buybacks to $6 billion. However, it purchased only $5.19 billion, while Treasury yields continued to rise.
The episode suggests that Treasury buybacks can improve market liquidity and help manage supply-demand conditions, but they are unlikely to reverse the structural forces driving long-term yields. Inflation, fiscal deficits and persistent demand for long-term capital remain more powerful forces in determining the cost of government borrowing.
Rising Oil Prices Add to Inflation and Rate-Hike Risks
Higher oil prices are adding another layer of pressure to the Treasury market. Rising energy costs could push inflation expectations higher and encourage investors to increase their bets on further Federal Reserve tightening.
Market-implied odds of a rate hike have risen to 71%, suggesting that the bond market has already started pricing in a more restrictive policy path even before the CPI release.
The key issue is therefore not simply the outcome of a single inflation report. Markets are also assessing whether energy costs, tariffs and supply-chain pressures could cause underlying inflation to lose its downward momentum.
If these pressures prevent inflation from continuing to cool, the Federal Reserve could face greater difficulty in easing policy. That would keep pressure on both short-term rate expectations and longer-term Treasury yields.
AI Infrastructure Investment Is Increasing Demand for Long-Term Capital
Another structural factor is the capital expenditure boom surrounding AI infrastructure. Heavy corporate borrowing to finance data centers, computing capacity and related infrastructure means the U.S. government is no longer the only major claimant on long-term capital.
As governments and corporations compete simultaneously for funding, investors may demand higher yields to absorb the growing need for long-term financing. This creates an additional challenge for the Treasury Department because buybacks alone cannot eliminate broader competition for capital.
The implication is that long-term Treasury yields are increasingly being shaped by the overall cost and availability of capital rather than by Treasury operations alone.
Why Some Investors See Higher Treasury Yields as Fundamental
Stanley Druckenmiller has argued that, given the current scale of capital spending and competition for funding, Treasury yields may be "a little low." His view highlights a broader shift in how some investors interpret the latest rise in yields.
Rather than treating higher yields solely as a temporary reaction to market sentiment or policy expectations, investors may increasingly see them as a reflection of underlying fundamentals.
This distinction matters because it changes the question facing the Treasury market. If higher yields are primarily driven by structural demand for capital, policy operations may have less ability to push borrowing costs back down without addressing the underlying supply and demand dynamics.
What Higher CPI Could Mean for Treasury Yields and Crypto Liquidity
The next major test will be the CPI release. If inflation comes in hotter than expected, rate-hike expectations and long-term Treasury yields could reinforce each other, further tightening financial conditions.
For crypto and other risk assets, higher Treasury yields can increase the pressure on market liquidity as investors reassess the relative attractiveness of riskier assets under a higher-rate environment. A hotter CPI could therefore create additional headwinds for crypto market liquidity.
If inflation instead moderates, markets will have to reassess whether elevated Treasury yields can retreat as rate expectations ease. The reaction will depend not only on the CPI figure itself, but also on whether investors believe the structural demand for long-term capital remains strong enough to keep yields elevated.
Treasury Market Shifts From Policy Support to Fundamental Pricing
The central question facing the Treasury market is no longer simply how much debt the Treasury Department can buy back, but what level of yield investors require to absorb the growing supply of long-term U.S. debt.
This marks a gradual shift in the market debate. Rather than focusing solely on whether policy tools can influence Treasury prices, investors are increasingly asking whether those tools can overcome the underlying fundamentals driving the cost of capital.
With inflation, energy prices, fiscal deficits and AI-related capital demand all contributing to the outlook, the direction of Treasury yields will remain closely tied to whether the market sees these pressures as temporary or structural.
