Higher rates expose governments’ debt dilemma
Can Governments Afford These Interest Rates?
Persistent inflation and rising borrowing costs are forcing governments to confront how they will finance large liabilities without destabilizing markets or currencies.
- 1Higher rates are increasing governments’ debt-interest burdens just as inflation keeps pressure on central banks.
- 2The Bank of England’s quantitative-tightening choices could influence gilt supply, yields and future borrowing costs.
- 3Financial repression, currency devaluation and capital controls emerge as possible responses to unsustainable public finances.

John Stepek argues that financial repression may return as governments struggle with debt interest, and says holding gold remains reasonable.
The brief
Merryn Somerset Webb and John Stepek begin with AI’s competing narratives: existential risk, corporate responsibility and incentives that can encourage both dismissal and exaggeration.
They then ask whether higher borrowing costs could puncture the AI investment boom, contrasting the Federal Reserve’s rate decision with the Bank of England’s stance.
The Bank of England’s quantitative-tightening plans take center stage, including its pause in long-dated gilt sales and the effect of bond supply on yields.
Persistent inflation and a possible 25% energy-price rise could keep UK rates higher, increasing the share of government revenue absorbed by debt interest.
The discussion’s sharpest turn considers financial repression, currency devaluation and even capital controls as governments search for ways to manage their liabilities.
