Global Long-Term Bond Yields Rise to Post-Financial Crisis Highs, More Debt Means Rates Resemble Credit Ratings
Global long-term government bonds are facing a sell-off, with the yield on the 30-year U.S. Treasury rising to about 5.31%, the highest since 2007; the yield curve spread between 2-year and 30-year U.S. Treasuries has widened to 113 basis points.
The U.S. Treasury recently issued $42 billion in 10-year and $25 billion in 30-year bonds, with awarded yields of 4.683% and 5.216%; the latter is the highest financing cost for that maturity since 2001, reflecting investors' demand for higher term compensation.
The yield on France's 30-year government bonds has risen to nearly 4.9%, the highest since mid-2008; the UK's long-term bond yield is close to 6%, while Canada's 30-year yield has reached its highest level since 2010, and Germany's yield is at its highest since 2011.
The yield on Japan's 10-year government bonds has risen to about 2.93%, the highest since 1996; the 30-year yield is around 4.06%, close to the historical high set in May. Expectations of potential interest rate hikes by the Bank of Japan, yen pressure, and massive government debt are driving up long-term financing costs.
The rise in U.S. long-term Treasury yields occurs against a backdrop of relatively mild inflation data and market expectations that the Federal Reserve will remain on hold in the short term, indicating that the sell-off is driven not only by recent policy rate expectations but also reflects a repricing of long-end term premiums, supply, and fiscal risks.
Contributing factors include the nearly $2 trillion annual fiscal deficit in the U.S., a national debt close to $40 trillion, ongoing expansion of long-term government bonds, and increased corporate financing demand driven by the AI investment boom; traditional long-term bond buyer demand has weakened, further diminishing the absorption capacity for new supply.
In market mechanisms, when the government simultaneously increases long-term bond issuance, inflation remains persistently above central bank targets, and investors are concerned about fiscal sustainability, buyers will demand higher yields to compensate for term, inflation, and credit dilution risks. Rising yields mean falling bond prices and will elevate the discount rates for housing mortgages, corporate bonds, private credit, infrastructure financing, and stock valuations. Beneficiaries include holders of cash and short-term bonds that can lock in high coupons; those under pressure include highly leveraged governments, refinancing companies, long-duration growth stocks, and assets reliant on low-rate valuations.

After the 2008 financial crisis, major central banks suppressed long-term government bond yields through zero interest rates, quantitative easing, and asset purchases, allowing governments to extend debt maturities at extremely low costs. The current market is reversing this structure: the Federal Reserve is no longer a continuous price-sensitive buyer of long-term Treasuries, and the Bank of Japan is gradually withdrawing its strong suppression of its domestic yield curve, while traditional overseas reserve managers and pension funds have reduced marginal demand for ultra-long bonds. As a result, long bond yields have begun to rise independently of short-term policy rates.
The change in funding pathways lies in the Treasury converting new deficits into more medium- to long-term bond supply, forcing investors to reallocate between 'buying government long bonds, buying high-coupon corporate bonds, buying AI capital expenditure-driven stocks, or holding short-duration cash instruments.' Increased AI infrastructure financing has raised corporate demand for long-term capital, competing with government bond issuance for the same pool of long-term savings; when supply grows faster than the demand from insurance companies, pension funds, foreign central banks, and asset managers, rising yields are not just short-term trading fluctuations but necessary price adjustments for market clearing.
This can be contrasted with the 'taper tantrum' of 2013 and the 2022 UK LDI crisis. The core of 2013 was the expectation of reduced bond purchases by the Federal Reserve, while the core of the 2022 UK situation was the shock from fiscal plans and pension leverage unwinding; the current situation is more akin to a combination of cross-border fiscal expansion, persistent inflation, and structural contraction of long-term buyers. The rise in Japanese yields is particularly significant: if Japanese institutions find domestic bond yields attractive, they may reduce overseas bond allocations or repatriate funds, thereby impacting the marginal demand for global dollar, euro, and pound bonds.
Essentially, this represents a shift in pricing power: the pricing power of long-term funds is shifting from central bank balance sheets back to private buyers demanding real returns. The mechanism is that short-term rates are directly anchored by central bank policy, while long-term rates equal future short-term rate expectations plus term premiums; when investors are concerned about inflation, supply, fiscal discipline, and monetary purchasing power, term premiums will rise, meaning that even if the central bank does not raise rates, the long-term financing costs for governments and corporations will still be elevated by the market. Long-term bonds are no longer just safe-haven assets but have become real-time indicators of fiscal credibility and inflation expectations.
