European bond yields hit multi-year highs as Hormuz tensions escalate

European government bond yields rose sharply on Friday, August 14, with Germany's 30-year yield climbing to around 3.72% — its highest level since 2011 — and France's 10-year yield breaching 4% for the first time since 2009, as the ongoing U.S.-Iran standoff over the Strait of Hormuz continued to rattle markets.lse+1

The sell-off in European bonds came on a day when the United Arab Emirates blamed Iran for firing drones at two tankers operated by state-owned Abu Dhabi National Oil Company (ADNOC) as they transited the strait, an escalation that the UAE called "acts of piracy." The United States said on Thursday it could maintain its naval blockade of Iran indefinitely, while Tehran has refused to reopen the waterway until Washington removes economic sanctions and releases frozen Iranian assets.apnews+2

Fiscal Pressures Compound Geopolitical Risks

The yield surge reflects more than geopolitical tensions. Germany's 10-year benchmark rose 5 basis points to 3.19%, up 6 basis points on the week, while France's 10-year yield jumped roughly 10 basis points intraday to approximately 4.04%. Analysts pointed to mounting fiscal spending across major European economies — Germany plans to issue approximately €82 billion in 10-year federal bonds in 2026 to fund expanded defense and infrastructure programs, while France's persistent deficits continue to weigh on investor sentiment.news.futunn+2

The widening spread between French and German yields signals that investors are demanding a higher risk premium for France's fiscal trajectory. European equities felt the pressure: France's CAC 40 fell 0.16%, the UK's FTSE 100 declined 0.21%, and Italy's FTSE MIB dropped 0.20%, though Germany's DAX bucked the trend with a 0.51% gain.investinglive+1

ECB Rate Expectations Firm

Traders in money markets were pricing in around 40 basis points of further European Central Bank tightening this year, up about 2 basis points from the start of the week. Nordea forecasts three quarterly 25-basis-point hikes — in September, December, and March 2027 — bringing the deposit rate from 2.25% to 3%.corporate.nordea+2

"We see more chances for rate hikes to be priced out and Bund yields to test the lower bound of their range," said Christoph Rieger, head of rates at Commerzbank, pointing to subdued U.S. inflation data that could cool expectations. U.S. retail sales released Friday fell 0.6%, well below the 0.1% gain expected, while the University of Michigan consumer sentiment index dropped to 51.0 — data that weighed on the dollar but failed to halt the rise in longer-term yields on either side of the Atlantic.lse+1
