Sterling at a 17-Month High Against the Euro: Reading a Session Driven by French Unrest

Key takeaways

1. Sterling rose 0.25% to 84.11 pence per euro on Monday 19 October after touching 83.95, its strongest level since May 2025 (Reuters).

2. The euro fell 0.14% to $1.1223 as violent weekend protests in France widened the French–German 10-year spread to 144 basis points, from about 110 in late September (Reuters).

3. When a cross moves sharply, check which leg is doing the work: here the euro weakened while sterling was flat against the dollar.

The development

The euro opened the week under pressure after some of the worst unrest France has seen in years. President Emmanuel Macron condemned "shocking" scenes of violence on the sidelines of cost-of-living protests, and Prime Minister Sebastien Lecornu asked local authorities to impose partial curfews (Reuters, 19 October).

In Asian trade the euro fell 0.1% to $1.1230; by the New York session it was down 0.14% at $1.1223 (Reuters). The spread between French government bonds (OATs) and German Bunds widened to 144 basis points, from around 110 in late September. Against sterling the move was larger: the pound rose 0.25% to 84.11 pence per euro after reaching 83.95, the strongest since May 2025, while it slipped 0.05% against the dollar to $1.3327 (Reuters). European natural gas prices also rose to a four-year high.

Market transmission

The French story reaches the euro mainly through the bond market. A wider OAT–Bund spread signals that investors demand more compensation to hold French debt, which raises questions about fiscal policy and political stability in the euro area's second-largest economy. One strategist told Reuters that the unrest matters for the euro mainly through French bonds rather than directly.

Sterling benefited by contrast. Stronger-than-expected UK growth data for August and reduced concern about the UK fiscal path supported the pound (Reuters). Because EURGBP is a cross between two European currencies, it isolates relative European risk better than either pair against the dollar.

What to monitor next

• The OAT–Bund spread in the London session (07:00–16:00 UTC), as the clearest gauge of French risk.

• UK labour-market data on Tuesday 20 October and September CPI on Wednesday 21 October, both at 06:00 UTC.

• Moody's scheduled review of France's credit rating on Friday 23 October (Newsquawk).

• European gas prices, which weigh on the euro area's terms of trade.

Reusable lesson

Decompose a cross into its two dollar legs. On Monday, EURUSD fell while GBPUSD was nearly unchanged, so the EURGBP move was a euro story. That tells you the next information to watch is French and euro-area news, not UK data. Reversing the logic, a cross move driven by sterling would point you to the UK calendar.

Invalidation and risk

The euro weakness could reverse quickly if French authorities restore calm or if budget negotiations produce a credible outcome, narrowing the bond spread. Strong UK data are already partly priced, so a softer UK CPI print on Wednesday could reduce sterling's support. Political headlines can arrive outside normal hours and gap prices at the Asian open.
