Political fragility has significantly increased debt servicing costs for European governments, with the UK bearing the largest burden. Research by Allianz Trade indicates that political instability in Westminster has added roughly $35 billion to UK taxpayers' debt-servicing charges since the end of quantitative easing in 2022. This figure represents a persistent premium investors demand for holding UK government bonds, driven by repeated bouts of political uncertainty over tax and spending decisions.
The infamous "mini" Budget in September 2022, proposed by Liz Truss, exemplified this, causing long-term gilt yields to surge by as much as 120 basis points and leading investors to label it a "moron premium." The UK government is projected to pay around $110 billion in debt interest this year alone, nearly double the defense budget.
Across eight European countries tracked by Allianz, political fragility has added between 2% and 5% to annual debt servicing costs. The cumulative cost for all these countries combined stands at approximately $98 billion since 2022. The UK accounts for the largest share of this, with its costs over four years totaling about $41 billion euros (approximately $35 billion USD). This underscores that bond markets are now more sensitive than ever to political shifts across Europe, with a 10-point decline in political stability (ICRG's 100-point scale) increasing sovereign bond yields by an average of 106 basis points, according to Bruegel.
