The Limits of Big Government: Rising Bond Yields Signal End of Post-Pandemic Fiscal Illusion

In late 2021, The Economist devoted significant coverage to what it described as the dawn of a 'new era of big government,' highlighting trillions in pandemic spending and expanded welfare states across advanced economies as a necessary response to crisis. By October 2025, the same publication warned of looming 'fiscal crises' in the rich world, with public debt near historic highs and bond markets pushing back against unchecked borrowing.

This shift reflects a broader market verdict now unfolding in 2026. Sovereign bond yields have surged across developed economies to multi-decade highs: U.S. 10-year Treasuries briefly exceeded 5%, UK gilts hit levels unseen since 2007, German Bunds reached 2011 peaks, and French yields surpassed 4% for the first time since 2008. Drivers include persistent fiscal deficits (averaging over 4% of GDP in advanced economies), heavy issuance, inflation concerns, and reduced central bank support.

France exemplifies the strain. Public debt is projected to reach 119.3% of GDP in 2026 and 121.7% in 2027—the highest since 1978—amid deficits around 5.4% of GDP and subdued growth revised down to 0.5%. Similar pressures appear in the UK, Japan, and the U.S., where interest costs now rival defense spending.

The original analysis correctly identifies that repeated stimulus and expansive fiscal-monetary coordination have fueled inflation and stagnation rather than sustainable growth. Central bank losses and bond market resistance further undermine the prior paradigm of unlimited intervention. While geopolitical factors play a role, the core issue remains structural: incentives distorted by high taxation, subsidies, and regulation erode wealth creation.

Deeper connections emerge in how these dynamics intersect with demographics and productivity. Aging populations amplify entitlement pressures, while AI-driven capital demands compete with government borrowing for savings. Without credible paths to fiscal balance—through growth-oriented reforms, deregulation, or spending restraint—markets may force adjustments via higher rates, crowding out private investment and prolonging affordability crises.

Evidence from bond markets and official forecasts suggests the 'big state' model has reached practical limits, validating critiques of multiplier myths and statism. Citizens and policymakers face a choice between restoring credibility through restraint or risking prolonged stagflationary pressures.
