$40T U.S. Debt and Japan Rate Risks Pressure Global Bonds | Bitunix Market Update

September 2, 2026 — Global bond markets are facing renewed pressure as high debt levels and elevated interest rates converge across the United States and Japan. The U.S. 10-year Treasury yield has risen to around 4.8%, while the 30-year yield remains above 5%, with the Treasury Department's expanded buyback program providing only limited support.

The market is increasingly looking beyond short-term liquidity conditions toward the structural forces behind long-term yields, including the $40 trillion U.S. debt burden, large fiscal deficits, persistent inflation, and the term premium. At the same time, a more hawkish Bank of Japan could encourage Japanese capital to return home, adding another potential source of pressure to global bond markets.

U.S. Treasury Yields Remain Elevated as Fiscal Pressure Builds

The U.S. 10-year Treasury yield has risen to around 4.8%, while the 30-year yield remains above 5%. The limited impact of the Treasury Department's expanded buyback program suggests that long-term Treasury pricing is increasingly being driven by structural factors rather than short-term liquidity conditions alone.

With U.S. government debt approaching $40 trillion, large fiscal deficits and substantial long-term financing needs are increasing the compensation investors may demand to hold longer-dated government debt. This is reflected in the growing importance of the term premium in Treasury pricing.

Treasury buybacks can improve market liquidity and temporarily support longer-dated securities, but they cannot fundamentally eliminate the supply pressure created by continued government borrowing. As a result, the direction of long-term Treasury yields remains closely tied to fiscal policy, inflation expectations, and global demand for U.S. debt.

Fed Rate-Hike Expectations Keep Pressure on U.S. Rates

Federal Reserve policy remains another important source of pressure. At Jackson Hole, Fed Chair Kevin Warsh emphasized that PCE inflation remains at 3.7% and that underlying inflation has not improved sufficiently, suggesting that the Fed still has more work to do to bring inflation back toward its 2% target.

Several Fed officials have also recently argued that monetary policy may not yet be restrictive enough. With the U.S. economy remaining relatively resilient, the Federal Reserve has limited room to ease policy quickly.

This creates a difficult combination for the Treasury market. Short-term yields remain supported by rate-hike expectations, while long-term yields face additional pressure from fiscal supply and the term premium. Even without another Fed hike, long-term funding costs can therefore remain elevated.

Bank of Japan Normalization Adds Pressure to Global Bonds

The pressure is not limited to U.S. Treasuries. The Bank of Japan is also signaling a more hawkish policy stance, with Governor Kazuo Ueda and board member Hajime Takata highlighting upside risks to inflation.

Japan's 10-year government bond yield has risen to around 3%. If the Bank of Japan proceeds with another rate hike in September, the relative attractiveness of Japanese domestic assets could increase further.

This could encourage Japanese investors to repatriate capital, potentially reducing demand for overseas bonds and creating additional selling pressure on U.S. Treasuries. The effect would extend beyond Japan and the United States, as global investors reassess the relative returns and funding costs across major bond markets.

The broader implication is that global bond pricing is increasingly being shaped by U.S. fiscal deficits, Japanese monetary normalization, and elevated real interest rates at the same time.

What Higher Long-Term Yields Mean for Gold

Gold faces a more complicated outlook under these conditions.

Higher Treasury yields typically increase the opportunity cost of holding gold, while a stronger U.S. dollar can add further pressure to the precious metal. If rising yields are primarily driven by expectations for additional Fed tightening, gold could therefore face greater short-term headwinds.

The picture changes if long-term yields rise mainly because of fiscal risks and a higher term premium. In that case, elevated Treasury yields may themselves reinforce concerns about U.S. debt sustainability and fiscal credibility.

Gold could then retain its appeal as a hedge against longer-term fiscal and credit risks, even while interest rates remain high. The key variable is therefore not simply whether Treasury yields rise or fall, but why they are moving.

Crypto Markets Remain Sensitive to Dollar Liquidity

Cryptocurrencies face a different transmission mechanism. Bitcoin and other high-volatility assets remain particularly sensitive to changes in dollar liquidity, real interest rates, and broader risk appetite.

If U.S. employment and inflation data remain strong enough to reinforce expectations for additional rate hikes, elevated Treasury yields could continue to constrain valuations across high-beta assets. Higher risk-free returns increase the opportunity cost of holding assets with greater volatility.

Conversely, if economic data weaken materially and long-term Treasury yields begin to decline, financial conditions could provide more room for equities, gold, and crypto assets to recover.

For Bitcoin, the most important variables therefore remain the interaction between U.S. inflation, employment, Treasury yields, and dollar liquidity, rather than the Fed policy rate in isolation.

September Outlook: Monetary Tightening or Structural High Rates?

The central question for September is whether elevated interest rates remain primarily the result of monetary tightening or evolve into a longer-term structural phenomenon driven by fiscal pressure and global capital supply and demand.

If stronger economic data reinforce rate-hike expectations, U.S. Treasuries and high-valuation assets could remain under pressure. Meanwhile, a more hawkish Bank of Japan could add another layer of competition for global bond capital.

If economic activity weakens materially and inflation continues to moderate, declining long-term Treasury yields could create more liquidity space for risk assets. Gold could also benefit if falling yields are accompanied by a weaker dollar and continued concerns over fiscal sustainability.

For global markets, the key issue is therefore the interaction between Fed policy, long-term Treasury yields, U.S. fiscal conditions, and Japanese monetary normalization. These factors will determine whether the current high-rate environment remains a temporary phase of monetary tightening or becomes a more persistent constraint on global asset valuations.
