Eurozone bond yields surge after Trump declares Iran ceasefire ‘over’

Eurozone government bond yields surged on Wednesday to their highest levels in roughly a month after U.S. President Donald Trump declared the memorandum of understanding underpinning the ceasefire with Iran was "over," sending oil prices sharply higher and reigniting expectations of further European Central Bank tightening.

Oil Shock Drives Selloff

Germany's 10-year Bund yield, the benchmark for the 21-member eurozone, climbed as high as 3.076% on Wednesday, up from 2.991% at the session low, according to Wall Street Journal market data. The move came as Brent crude jumped roughly 5% following Trump's remarks at the NATO summit in Turkey, where he called the MoU with Iran "a waste of time" and said the agreement was finished.wsj+4

France's 10-year OAT yield rose to 3.90%, its highest level since 2009, according to Il Sole 24 Ore Euronext N.V.. The French yield had already touched that threshold in May amid broader fiscal concerns, but Wednesday's oil-driven inflation fears pushed it back to that level. Trading Economics data showed the French 10-year yield rose 12 basis points from the prior session.lemonde+2

ECB Rate Path Repriced

The bond selloff reflected a swift repricing of ECB rate expectations. The central bank raised its deposit rate to 2.25% from 2% at its June 11 meeting — its first hike since 2023 — to combat inflation driven by the Iran war's impact on energy costs. Policymakers had since signaled patience, with Reuters reporting in late June that the rapid retreat in oil prices had eased the urgency for further action.reuters+2

But Trump's declaration upended that calculus. Prior to Wednesday, money markets had priced in roughly a one-in-three chance of a July 23 hike, with a full increase not expected until October. The renewed geopolitical shock is now likely to bring forward those expectations, analysts said.reuters+1

Fragile Equilibrium Shattered

The escalation marks the collapse of a diplomatic framework that had briefly calmed markets. The U.S. and Iran signed a memorandum of understanding in June calling for an immediate cessation of hostilities and the reopening of the Strait of Hormuz to shipping. Oil prices had retreated from crisis highs near $90 a barrel to below $73 by early July.reuters+1

The ECB next meets on July 23. One ECB insider told Reuters last month that it would take a new spike in oil above $100 per barrel to prompt a rate increase at that meeting. With Brent now surging from pre-crisis lows, that threshold may be approaching faster than policymakers anticipated.finance.yahoo
