The euro slid by more than 2% against the British pound in October, marking its worst monthly performance since July 2022. The primary driver was the sharp contrast between an emerging fiscal crisis in France and unexpectedly disciplined budget policy in the UK.

Britain’s Prime Minister Andy Burnham’s maiden budget proved so cautious that markets were immediately reassured. The 10‑year gilt yield obediently fell to a five‑week low of about 5.25%. Citigroup strategists promptly lifted their view on UK bonds, while analysts at asset manager Legal & General hailed London as “Europe’s most responsible player.”

Across the Channel, the picture looks radically different. Paris’ attempts to plug a massive budget hole have pushed borrowing costs to 25‑year highs. With national elections looming, France has been shaken by street protests over the rising cost of living, and the political turmoil is dragging the euro lower. Wells Fargo strategists expect EUR/GBP to slide to about 0.83 by year‑end.

Rabobank notes with some irony that the UK still faces its own fiscal challenges, leaving sterling looking weak versus the dollar. Yet in light of France’s financial troubles, Britain now appears to investors as an island of relative stability.
