London stocks opened slightly weaker on Thursday as investors weighed conflicting signals surrounding ongoing negotiations between the United States and Iran, despite increasingly optimistic comments from U.S. President Donald Trump regarding the possibility of a diplomatic agreement.
By 07:14 GMT, the FTSE 100 had fallen 0.28%, while European markets showed a firmer tone, with Germany’s DAX rising 0.20% and France’s CAC 40 gaining 0.41%. Sterling was broadly stable against the dollar, with GBP/USD up 0.18% at 1.3621.
Trump signals optimism over potential Iran agreement
Market sentiment was influenced by comments from President Trump, who told reporters at the White House that discussions with Tehran over the previous 24 hours had been “very good” and that reaching a deal remained “very possible.”
In later remarks to PBS, Trump said he believed an agreement could potentially be finalised before his scheduled visit to China next week, although he warned that military action could resume if negotiations fail.
Iran’s Foreign Ministry stated that no formal response had yet been delivered to Washington’s latest proposal, with diplomatic communication continuing through Pakistani mediators.
Reuters, citing both a Pakistani source and an individual briefed on the talks, reported that the two sides were nearing agreement on a short memorandum aimed at formally ending the conflict. Meanwhile, Axios reported that a proposed 14-point framework included commitments from Iran not to pursue nuclear weapons development and to suspend uranium enrichment activities for at least 12 years.
Iranian officials issue warnings amid ongoing talks
Despite the diplomatic progress, tensions remained elevated. A senior official from the IRGC Navy warned that any renewed US military action would trigger a response “beyond the enemy’s calculations.”
Iran’s parliamentary speaker also criticised Washington’s strategy around the Strait of Hormuz, describing it as “Operation Trust Me Bro” and claiming the approach had failed.
