Advanced economies face tighter monetary options as demographic and fiscal strains build
Central banks under pressure

Rising old-age dependency and weaker public finances are reshaping how central banks can respond to inflation across advanced economies. Economist Charles Goodhart says those pressures are limiting the effectiveness of interest-rate policy and increasing the risk that fiscal needs constrain monetary independence.

Highlights

  • Goodhart and Pradhan argue that advanced economies face constrained inflation management as aging populations, deteriorating dependency ratios, and weak fiscal positions reverse past disinflationary trends.
  • Goodhart warns that fiscal dominance will increase pressure on central banks, making governments more resistant to policy tightening needed to return inflation to target levels.
  • Policymakers may need closer fiscal-monetary coordination or demand-restraining tools like financial repression, though these introduce distortions; near-term AI-driven data centre and energy spending is inflationary.

Goodhart book thesis on policy constraints

As reported by Financial Times, Goodhart argues in his new book with Manoj Pradhan, The Unanchored Central Banker, that worsening fiscal positions and adverse demographic trends are making inflation management harder for central banks. He says the disinflationary era from the 1990s to around 2020 is driven less by central bank action than by a powerful labour supply shock, including China and eastern Europe joining the global trading system, lower fertility rates and rising female labour-force participation.

He says those forces are now reversing as labour-force growth slows, the number of older people rises and dependency ratios deteriorate. In his view, this shift, combined with a much weaker fiscal backdrop than he and his co-author had previously expected, means monetary policy cannot easily operate in its conventional form, especially through higher interest rates.

Goodhart says fiscal dominance is likely to place increasing pressure on central banks because governments are far less comfortable with rising borrowing costs than with the long period of falling nominal and real rates. He says that in advanced economies, central banks are likely to face greater resistance when trying to tighten policy enough to bring inflation back to target.

On possible alternatives, he says policymakers may have to consider closer fiscal-monetary coordination or other tools to restrain demand, including forms of financial repression, though he notes such approaches bring distortions and difficult trade-offs. He also says AI's long-term impact remains uncertain, while current spending on data centres and energy is inflationary rather than disinflationary in the near term.

Our earlier article on April U.S. household finances highlighted that PCE inflation remained well above the Federal Reserve’s 2% target even as consumer spending stayed resilient and income growth flattened. We noted that weakening household balance sheets and the gap between core PCE and core CPI were complicating the case for near-term rate cuts and keeping policy debate focused on how tight conditions may need to remain.
