Euro falls to 0.83825 pounds as French bond yield hits 5%

Key Facts

The euro fell against sterling on Wednesday, 21 October 2026, with a reference rate of 0.83825 pounds, according to the European Central Bank, as French bond yields climbed to a new high. The single currency's reference rate stood at 0.84028 pounds in the previous session, with the comparison between the two reference rates showing sterling extending its gains against the euro. In debt markets, the yield on French ten-year government bonds reached 5% on Wednesday, according to Reuters. The agency described the level as the highest in 24 years, as French markets faced fiscal and political pressures. The currency and bond moves coincided with an acceleration in British inflation in September from the previous month's reading.

Britain's Office for National Statistics reported that annual consumer price inflation rose to 3.5% in September from 3.1% in August. The office identified transport as the largest upward contributor to the change in the annual rate, with motor fuels playing a prominent role within the category. In its bulletin, it said "transport, particularly motor fuels, made the largest upward contribution," identifying the main driver of the month's acceleration in inflation. In another sign of British price pressures, Investing reported that core services inflation reached 3.7% in September. The website's report linked the reading to stronger expectations of a Bank of England interest rate increase in November, with the bank's base rate at 3.75% and its inflation target at 2%.

In France, data from the National Institute of Statistics and Economic Studies showed public debt rising to 119.0% of gross domestic product at the end of the second quarter, from 117.5% at the end of the first quarter. French public debt stood at 3,595.5 billion euros after increasing by 59.6 billion euros during the quarter, according to the institute. On the budget, Reuters reported as discussions began that Prime Minister Sebastien Lecornu was seeking to reduce the deficit next year. Lecornu is targeting a deficit of 5% of gross domestic product in 2027, compared with an estimated 5.4% for the current year, 2026. The plan places the deficit reduction target alongside the rise in the debt stock and its ratio to output in the second quarter, while Reuters also cited widespread protests across France among the pressures facing its markets.

Bond market pressures extended to the spread between French and German yields, which reached about 157 basis points, according to Reuters. The French yield premium thus approached levels last seen in 2011, as the French ten-year yield reached 5%. The euro had come under an earlier wave of pressure in early October, when Reuters coverage linked its moves to fears of contagion from turmoil in French bonds. On 5 October 2026, the euro fell below 1.12 dollars, hitting its lowest level against the U.S. currency in 17 months, according to the agency. The euro also declined against sterling, the Swiss franc and the Japanese yen in that session, alongside its fall against the dollar.

On French economic activity, the overall business climate index stood at 96 points in September, according to the National Institute of Statistics and Economic Studies. The index fell one point from the previous month, adding a deterioration in the business climate to the backdrop of rising public debt and bond market pressures. In Britain, annual inflation of 3.5% exceeded the Bank of England's 2% target, while the announced base rate remained at 3.75%. The British picture thus combines accelerating consumer prices, a contribution from transport to the increase, and core services inflation of 3.7%, according to Investing's report. The website's expectations of a rate increase in November relate to the bank's next meeting, with its decision scheduled for 5 November 2026.

Among upcoming events, the European Central Bank's official calendar includes Christine Lagarde's participation in an on-stage discussion at the Museum Reinhard Ernst in the German city of Wiesbaden. The National Institute of Statistics and Economic Studies will release the next French business climate reading on 22 October 2026, after September's index fell to 96 points. Markets are also looking ahead to Moody's review of France's credit rating on Friday, according to Investing's report, following the rise in yields and widening spread over German bonds. The Bank of England will then announce its next interest rate decision on 5 November 2026, following the release of September's reading showing an acceleration in British inflation. That will be followed by the next British inflation report on 18 November 2026, according to the date announced by the Office for National Statistics.
