A synchronous sell-off has pushed the yields of major long-term bonds to levels unseen in many years, and in some cases, decades. The yield on 30-year US Treasury bonds reached approximately 5.25%—the highest level since 2001—while the yield on 30-year German Bunds approached 3.73%—the highest level since 2011.
"Good morning from Germany, where the bond market is sending an unambiguous signal: the yield on 30-year German Bunds has risen to 3.73%—the highest level since 2011," wrote German journalist, author, and senior financial editor Holger Zschaepitz on X. "Germany now pays as much for borrowing as it did during the euro crisis era. The era of ultra-cheap money is over."
The yield on long-term French OAT bonds (short for Obligations Assimilables du Trésor) has returned to levels characteristic of the global financial crisis period. The yield on Japan's 5-year government bonds rose above 2.14%, marking a clear break after years of artificially soft monetary policy.
Investors Demand Compensation
Bond yield is the price governments pay investors for their money. When yields rise sharply, bond prices fall, and borrowing quickly becomes more expensive.
For over a decade after the 2008 financial crisis, central banks kept rates low and purchased vast amounts of government debt. This drove down yields, which in Europe and Japan even fell below zero. The pandemic doubled down on this trend: governments borrowed freely, and central banks prevented the market from asking inconvenient questions.
This scheme is collapsing. Investors providing credit for decades ahead now want protection from inflation, rampant bond issuance, and the erosion of the purchasing power of the cash they will get back.
"This week has seen a significant rise in the yields of long-term government bonds in heavily indebted European countries," explained Robin Brooks, a senior fellow in the Economic Studies Program at the Brookings Institution. "The situation is most notable in France, where the yield on 10y10y (orange line) and 10y20y (red line) has reached new historical highs."
Brooks added:
"The market's patience with fiscal dysfunction is running out."
Debt Markets Begin to Dictate Terms
The pressure point is fiscal policy—the growing gap between government spending and tax revenues. The United States, France, Japan, and other developed economies have accumulated massive debt while simultaneously increasing spending on defense, infrastructure, energy, and addressing aging populations.
In the US, according to recent estimates, the federal government's annual interest expense has exceeded $1 trillion. Each refinancing cycle locks in higher rates, turning yesterday's debt into tomorrow's budgetary problem.
France has its own political and budgetary issues. Bond market participants are closely watching spending negotiations and debt forecasts, contributing to the rise in French bond yields compared to German benchmark bonds.
Germany, long considered the eurozone's most reliable borrower, plans to increase spending on infrastructure and defense. This means a larger supply of bonds, i.e., more government debt competing for investors' money.
Central Banks Exit the Market
Japan's actions are hard to ignore, as the Bank of Japan for years suppressed yields through yield curve control—a policy designed to keep borrowing costs low. As it gradually unwinds this regime, markets are re-pricing for higher rates and much less official support.
"Cheap money was a temporary phenomenon," wrote the Wealthmoose account on X. "Debt is forever. Now the bond market is presenting the bill."
The same trend is visible elsewhere. The Federal Reserve and other central banks have shrunk their bond portfolios through quantitative tightening, thereby removing a major buyer from the market.
Governments are flooding the market with bonds while central banks are buying fewer and fewer of them. Private investors can buy these securities, but only at higher yields. This extra compensation is the term premium—the fee for locking money away in long-term bonds.
The Bill Extends Beyond Government Budgets
The rise in long-term yields primarily hits households through mortgage rates. In the US, 30-year mortgage rates often follow Treasury yields, making home buying and refinancing more expensive.
Businesses face higher rates when issuing long-term bonds. Stocks also suffer as higher bond yields attract cash flows and reduce the present value investors assign to distant future profits. Savers, pension funds, and insurance companies can earn more on bonds. However, this resource reallocation comes at a high cost to governments and borrowers accustomed to the cheap money era.
