U.S. Treasury yields rose and oil prices climbed on Monday, September 28, 2026, following President Donald Trump’s rejection of an Iranian peace deal and his stated plans to continue military strikes after the November midterm elections.
Diplomatic Breakdown Shakes Energy Markets
Financial markets reacted sharply to geopolitical friction in the Middle East at the start of the week. U.S. Treasurys rose in early European trade, while German 10-year Bund yields reached their highest level since 2009, driven higher by yet another setback in diplomatic talks. Market sentiment shifted after President Donald Trump turned down a seven-day truce proposal from Iran, and later said he expects further talks while also stating he rejected an Iran offer to reopen the Strait of Hormuz. Peace negotiators are currently pressing Tehran to make concessions on its nuclear program to revive ceasefire discussions with the United States. The diplomatic breakdown immediately impacted energy commodities. Oil prices climbed more than 2%, keeping the geopolitical risk premium elevated. S&P GSCI Petroleum Index data showed the index at 392.67 PTS, reflecting a 1st Jan change of +79.78%.
Stock Futures Slip Amid Central Bank Pressures
Stock futures across major U.S. indexes slipped early Monday. Dow Jones futures, S&P 500 futures, and Nasdaq futures all pointed downward as investors weighed rising commodity costs against upcoming economic releases, including crucial reports on U.S. inflation and jobs data.
Analysts warned that sustained high energy prices could constrain central bank policy. Tickmill Group cautioned that if energy costs remain elevated, central banks will have less room to ease monetary policy and greater incentive to keep inflation risks front and center. Meanwhile, investors increased bets on the Bank of England increasing interest rates in November.
Safe-Haven Assets Shift as European Equities Rise
European gas prices rose by more than 2%, matching the upward momentum in crude oil. The fading prospects for U.S.-Iran diplomacy also drove investors toward safe-haven assets, boosting the U.S. dollar while gold prices dropped as rising oil reinforced expectations of potential Federal Reserve rate actions next month. According to ING, the euro experienced a drop but might find its footing against the dollar over the course of the week since its latest pullback appears somewhat excessive. Bitcoin also fell during the session.
In the EMEA region, European shares rose Monday, boosted by pharmaceutical and auto stocks, while technology weakened. Eurozone government bond yields began the session slightly lower, though they could encounter a difficult week given that bond issuance will be heavy and oil prices remain high, while Treasurys might find some relief this week due to a scarcity of new supply. Meanwhile, U.K. sovereign bond yields ticked upward and stayed at elevated levels, with Treasury yields also climbing on the day amid pressure from higher oil prices, trading near yet staying under recent multiyear peaks.
Corporate Investments and Economic Outlooks
Marieke Blom, chief economist at Dutch bank ING, offered an economic perspective on Europe, arguing that an excessive despondency about its current condition as it faces a host of economic challenges may be one of the more pernicious, embarking on a mission to correct some of the gloomier misconceptions in a commentary titled Looking at Europe’s Glass as Half-Full.
In the meantime, the French utility and energy corporation TotalEnergies SE detailed its strategic targets for scaling up energy production past 2030, backed by annual capital expenditures amounting to billions of dollars. Between the years 2027 and 2032, the enterprise intends to direct $14 billion to $17 billion annually into investments, and anticipates that its oil and gas division will achieve a yearly output growth of approximately 2% to 3% spanning 2030 to 2035, supported by its internal pipeline of organic projects.
