European government bond yields moved lower on Monday as investors responded to the commencement of U.S.-Iran diplomatic discussions and prepared for comments from senior European Central Bank officials later in the day.
The benchmark 10-year German government bond yield eased to 2.975%, after having climbed about 7 basis points on Friday. The German two-year note, which is closely watched for signals about expectations for ECB policy, fell to 2.63%.
Markets across the euro zone experienced a volatile spell last week. Sovereign bonds initially rallied on reports that a Washington-Tehran peace agreement had been signed, but volatility returned on Friday when the U.S. unexpectedly withdrew from scheduled talks, triggering a sharp rise in oil prices and prompting a classic flight-to-safety trade in fixed income.
Over the weekend the geopolitical picture remained unsettled. U.S. and Iranian negotiators met in Switzerland on Sunday, but that diplomatic engagement was accompanied by heightened rhetoric: U.S. President Donald Trump warned of the possibility of new military strikes against Iran and linked that rhetoric to hostilities attributed to Hezbollah in Lebanon.
Iranian negotiators said privately that substantive progress was being made behind closed doors, but the absence of detailed public information kept many fixed-income investors wary.
Complicating the risk assessment for markets, conflicting accounts emerged about the status of the Strait of Hormuz. Iranian authorities asserted the strategic waterway had been closed again, yet maritime tracking data showed ships still transiting the passage. The divergence between those claims and observed shipping movements left markets navigating an unclear supply outlook for energy flows.
Attention in financial markets also turned to the European Central Bank. ECB President Christine Lagarde and Chief Economist Philip Lane were scheduled to speak later on Monday, and traders were looking for signals on how the bank plans to weigh lingering inflationary pressures - including those amplified by recent conflict-driven shocks - against tentative signs that hostilities in the Middle East may be subsiding.
Elsewhere in Europe, yields on British government gilts rose. The 10-year gilt yield climbed to 4.85%, while the two-year gilt yield increased to 4.25%. Those moves followed media reports that Prime Minister Keir Starmer was reportedly set to step down after an internal rival, Andy Burnham, won a parliamentary election contest, according to the reports cited in market coverage.
Market participants remained focused on the dual forces of geopolitical developments and central bank communications, both of which were driving intra-European moves in sovereign debt markets as investors sought clarity on future policy and supply risks.
